Joe Boland via Dr. Axe – When is the best time to take vitamins: morning or night? The timing of supplements can influence their absorption and effectiveness. Taking vitamins and supplements is a great way to support overall health, but timing matters when it comes to maximizing their benefits. Utilizing supplements at the right time can enhance their absorption and effectiveness, which begs the question: When is the best time to take vitamins and other supplements? While some vitamins and minerals work best when taken with food, others are better absorbed on an empty stomach. In addition, certain combinations can enhance or inhibit absorption, making it crucial to plan your intake accordingly. Understanding when to take supplements can help optimize their benefits. This guide, supported by scientific research, will help you determine the best time to take vitamins for maximum impact. When is the best time to take vitamins: morning or night? The timing of supplements can influence their absorption and effectiveness. Water-soluble vitamins, such as vitamin C and B vitamins, can provide an energy boost, making them ideal for the morning. Fat-soluble vitamins, including vitamins A, D, E and K, are best taken with meals for improved absorption, particularly meals with healthy fats, such as coconut oil, eggs, avocado, etc. On the other hand, some minerals, like magnesium, have a calming effect and may be better suited for nighttime use. While many people take their vitamins in the morning out of habit, the best time depends on the type of vitamin and how your body absorbs it. However, whenever you find is best for you, whether out of routine or for how you’ve found your body best responds, is the best time to take vitamins and other supplements. In fact, studies have relayed that taking vitamins consistently at the same time each day helps with adherence and absorption. Best time to take water-soluble vitamins Water-soluble vitamins, such as vitamin C and B-complex vitamins (including B12, B6 and folate), dissolve in water and are best taken on an empty stomach for maximum absorption. They dissolve in water and are not stored in the body, requiring regular intake. Vitamin C Vitamin C is best taken in the morning or midday on an empty stomach to enhance absorption. It’s a good idea to use your vitamin C early in the day to support immune function and reduce fatigue. Sunlight and other factors can lead to oxidation of vitamin C, which could lower its effectiveness. That’s why it’s recommended to take it early and store it in a cool, dark place. Ingesting probiotics with vitamin C can also lead to better absorption. B vitamins Research has shown that B vitamins help convert food into energy, making them most effective when taken in the morning. Since they play a role in energy production, they are best taken early to avoid sleep disturbances. You can take B vitamins with food, but it’s not necessary. It’s a good idea to take them with water or your morning beverage of choice. Taking B vitamins together, such as in a B-complex supplement, is ideal, as they work better together. Using them in combination with probiotics can also enhance their absorption. B-complex vitamins include: Vitamin B1/thiamine Vitamin B2/riboflavin Vitamin B3/niacin Vitamin B5/pantothenic acid Vitamin B6/pyridoxine Vitamin B7/biotin Vitamin B9/folate (folic acid) Vitamin B12/cobalamin The best time to take vitamins that are water-soluble is typically considered early and on an empty stomach, but you can take them any time of day that works for you. They also can be taken with or without food, along with water or your drink of choice. Best time to take fat-soluble vitamins Fat-soluble vitamins (A, D, E and K) are stored in the body’s fat tissues and liver. These vitamins require dietary fat for optimal absorption, making them most effective when taken with a meal containing healthy fats. To maximize benefits, take fat-soluble vitamins with breakfast, lunch or dinner. Here’s more on when is the best time to take vitamins that are fat-soluble: Vitamin D Studies have indicated that taking vitamin D with a meal containing fat increases its bioavailability. For example, a study published in the Journal of the Academy of Nutrition and Dietetics found that vitamin D absorption improved significantly when taken with a fat-containing meal. Doubling up by pairing vitamin D and vitamin K is a good idea, as vitamin K helps your body absorb more vitamin D. The best time to take vitamins D and K together is typically thought to be in the morning or afternoon, when the sun is out, since sunlight is the main way humans obtain vitamin D. Vitamin A Vitamin A is best taken with meals that contain healthy fats like olive oil, avocado or nuts to optimize absorption. It can be taken any time of time, and it’s a good idea to take it with the same meal (breakfast, lunch or dinner) every day if possible. Vitamin E Research has shown consuming vitamin E with healthy fats can boost its absorption greatly, so the best time to take vitamins like E is mealtime, whether that’s morning, noon or night. Vitamin K As mentioned, the best time to take vitamins that are fat-soluble are mealtimes, but vitamin K is a bit unique compared to other fat-soluble vitamins. Vitamin K stands out due to its three distinct forms: phylloquinone (vitamin K1), menaquinones (vitamin K2) and menadione (vitamin K3). K1 and K2 are found in foods (K1 in leafy greens, K2 in some animal foods) and often included in supplements, while K3 is rarely found in either. Both K1 and K2 can be taken at any time of day, but K2 supplements are best absorbed when paired with a meal or snack containing fat. For optimal results, try to take vitamin K separately from vitamins A and E, as they may interfere with each other’s absorption. On the other hand, combining vitamin K with vitamin D can be beneficial, as they work together to maintain healthy calcium levels and support strong bones. Best time to take multivitamins Multivitamins contain a mix of water-soluble and fat-soluble vitamins, making their timing slightly tricky. The best approach is to take them with a meal containing some fat to aid in fat-soluble vitamin absorption while ensuring water-soluble vitamins are utilized effectively. Multivitamins contain a combination of vitamins and minerals, some of which require fat for absorption while others do not. Because they often include B vitamins, which can boost energy, it is generally best to take multivitamins in the morning with food. Iron or magnesium However, if a multivitamin contains iron or magnesium, taking it later in the day may be preferable to avoid potential stomach discomfort. Research does suggest that taking multivitamins in the morning with breakfast improves compliance and absorption. Whether you opt for morning or night, consistency is key, so try to take your multivitamin at the same time each day if you can. Best time to take prenatal vitamins Prenatal vitamins are crucial for maternal and fetal health, often containing iron, folic acid and DHA, which are crucial for fetal development. Research has found that taking prenatal vitamins with food can reduce nausea, a common concern for pregnant individuals. Because iron absorption is optimized on an empty stomach but can also cause discomfort, taking prenatal vitamins with a light meal, such as breakfast, is recommended. Pregnant women can be prone to having sensitive stomachs during the morning, though, so some may prefer to take prenatal vitamins with dinner before bed. Here is a bit more on some prenatal vitamins to consume and the best time to take vitamins for pregnancy: Folic acid: Best taken in the morning on an empty stomach to enhance absorption. Iron: Should be taken separately from calcium-containing foods or supplements, as calcium inhibits iron absorption. DHA (omega-3s): Best absorbed with a meal containing healthy fats. It’s best to take prenatal vitamins at the same time every day for consistency’s sake. Best time to take minerals and other supplements When is the best time to take vitamins, minerals and other supplements not specified above? Here are some recommendations: Iron is absorbed best on an empty stomach but can cause stomach irritation. It’s best taken in the morning on an empty stomach with vitamin C for enhanced absorption, but it should not be taken with calcium or caffeine, which can make it harder to absorb. Ideally consume iron one to two hours before or after a meal. Known for its muscle-relaxing and sleep-promoting effects, magnesium may be best taken at night. You can also take magnesium in the morning with food or split into two doses divided between morning and night. More specifically, magnesium glycinate and magnesium threonate are better to take in the morning since they aid energy levels, while magnesium oxide and magnesium chloride may be best to take at night since they promote sleep. If consuming high doses (more than 500 mg) of calcium, split intake into multiple doses for better absorption. Similarly to iron, zinc should be taken one to two hours before or after eating a meal, and you can ingest it with or without water. You should not take it with fiber, calcium or iron, which can interfere with absorption. What vitamins should not be taken together? Certain vitamins and minerals can interfere with each other’s absorption: Calcium and iron: Compete for absorption. Take iron supplements separately from high-calcium meals or supplements. Zinc and copper: High doses of zinc can interfere with copper absorption. If supplementing both, take them at different times. Vitamin C and B12: Some research has suggested that high doses of vitamin C may reduce B12 absorption when taken together. Consider spacing them apart. Fat-soluble vitamins (A, D, E, K): Avoid taking high doses together, as they may compete for absorption. Vitamin C and iron: Vitamin C enhances iron absorption, but taking excessive amounts together may lead to gastrointestinal discomfort. It is best to consume them in moderate amounts. Calcium and magnesium: These minerals compete for absorption, so taking them together in high doses may reduce their effectiveness. Consider spacing them apart. Zinc and magnesium: High doses of zinc can interfere with magnesium absorption. To optimize benefits, take them at different times of the day. Conclusion Taking vitamins and supplements at the right time can enhance their effectiveness. To maximize the benefits of vitamins and supplements, it’s essential to take them when they can be utilized best and with the right combinations. Water-soluble vitamins like vitamin C and B-complex vitamins are best taken in the morning on an empty stomach, while fat-soluble vitamins should be taken with meals. Minerals like magnesium and iron have specific timing requirements for optimal absorption. For instance, magnesium may work better at night, and some nutrients should be spaced apart to prevent absorption interference. However, consistency appears to be the most important factor, so really the best time to take vitamins, minerals and other supplements is whenever you can on a consistent basis. Following a well-planned schedule based on research-backed guidelines can help you get the most out of your supplements. By aligning your supplement intake with your body’s needs, you can maximize their health benefits. Always consult with a healthcare professional before making significant changes to your supplement routine. To read the original article click here.

Vitamin D Deficiency Fuels Autoimmune Conditions, Dysregulating Immune Function

The AHA! Team — Fri, 22 Aug 2025 05:12:13 +0000

Lance D Johnson via Natural News – Autoimmune diseases have surged in lockstep with declining vitamin D levels, exposing a troubling paradox: as modern medicine advances, immune dysregulation grows more prevalent. Vitamin D transcends its common label as the “sunshine vitamin” by serving as a cornerstone of immune function and systemic health. Surprisingly, nearly one-third of Americans suffer from dangerously low levels, leaving them vulnerable to chronic illness. Recent scientific investigations highlight how this unseen deficiency exacerbates autoimmune conditions, including rheumatoid arthritis and multiple sclerosis, while also amplifying systemic inflammation. Beyond individual health, this crisis reflects broader societal failures — corporate interests have vilified sun exposure, public health policies neglect nutritional education, and modern lifestyles deprive people of natural vitamin D synthesis. Far from accidental, this deficiency epidemic highlights a troubling disconnect between our biological needs and the systems shaping our daily lives. Key points: Vitamin D regulates immune function, distinguishing between healthy cells and pathogens while suppressing inflammatory markers linked to autoimmunity. Deficiency escalates autoimmune risks, with studies showing 55% of rheumatoid arthritis patients and 42% of lupus sufferers lack sufficient levels. Low vitamin D correlates with MS progression, as every 10 ng/ml drop increases neuronal damage by 15%. Women face heightened vulnerability, with hormonal imbalances and conditions like PCOS exacerbating deficiency. Daily supplementation (5,000 IU) is essential to counteract food scarcity and sun deprivation. Vitamin D as the immune system’s master regulator Vitamin D is not merely a passive nutrient; it actively trains the immune system to distinguish between healthy cells and foreign pathogens. It accomplishes this by modulating inflammatory responses and suppressing autoimmune reactions. For instance, vitamin D promotes the production of regulatory T-cells, which act as immune peacekeepers by preventing misguided attacks on the body’s own tissues. Without sufficient levels, these protective mechanisms falter, allowing inflammation to spiral unchecked. Studies demonstrate that low vitamin D correlates with elevated autoimmune risks — 55% of rheumatoid arthritis patients and 42% of lupus patients exhibit significant deficiencies. Similarly, multiple sclerosis progression accelerates with each 10 ng/ml drop in vitamin D levels, increasing neuronal damage by 15-32%. Given these findings, maintaining optimal vitamin D status is not optional — it is a critical defense against immune dysfunction. The autoimmune crisis and vitamin D’s protective role Autoimmune diseases have surged in lockstep with declining vitamin D levels, exposing a troubling paradox: as modern medicine advances, immune dysregulation grows more prevalent. Functional medicine experts, such as Dr. Jennifer Bourgeois, emphasize that vitamin D deficiency disrupts immune tolerance — an essential process that prevents the body from attacking itself. Research published in Clinical and Experimental Rheumatology confirms that rheumatoid arthritis patients disproportionately suffer from insufficient vitamin D, while lupus studies reveal similar trends. Multiple sclerosis patients with low vitamin D levels face faster disease progression and more severe brain lesions. This data underscores vitamin D’s role in quelling inflammatory cytokines — molecules that fuel autoimmune destruction. To reverse this crisis, proactive intervention is essential, starting with widespread supplementation and sunlight exposure. Corporate interests, sunlight phobia and systemic sabotage Decades of corporate messaging have falsely demonized sun exposure, branding it as inherently dangerous while ignoring its role in vitamin D synthesis. The beauty and pharmaceutical industries have profited from this fear, aggressively marketing sunscreens and indoor lifestyles that disrupt natural vitamin D production. Dr. Katie Golden highlights the consequences: Over 20 million Americans now struggle with autoimmune conditions, many linked to chronic deficiency. Compounding the issue, modern dietary trends fail to fill this gap — breast milk often lacks sufficient vitamin D, and children weaned onto nutrient-poor juices risk deficiency early in life. Even vaccinations lose efficacy in individuals with low vitamin D, illustrating its broader immunological impact. Corporate profits from cosmetics and sunscreen overshadow an inconvenient truth: many beauty products contain toxins linked to autoimmune disease, while vitamin D itself helps detoxify such harmful compounds. A roadmap to recovery: Rebuilding immunity through vitamin D Restoring vitamin D to optimal levels — ideally above 50 ng/ml — requires daily supplementation, ideally 5,000 IU or more. While nutrient-dense foods like grass-fed liver and fatty fish offer support, modern lifestyles make supplementation indispensable. For women, addressing deficiency is particularly urgent; sufficient vitamin D halves breast cancer risk and mitigates conditions like PCOS. Despite these benefits, conventional medicine often overlooks deficiency’s role in disorders ranging from autism to diabetes. Functional medicine experts stress that autoimmune disease is not inevitable — rather, it results from systemic neglect of foundational health strategies. By prioritizing vitamin D replenishment, individuals can reclaim immune resilience and break the cycle of chronic illness. The solution lies not in passive acceptance but in proactive self-advocacy, demanding better public health policies and rejecting corporate-driven misinformation about sunlight and supplementation. The vitamin D crisis is a preventable epidemic rooted in misinformation and profit-driven health policies. Autoimmune disorders, chronic inflammation, and rising disease burdens need not be inevitable — they reflect measurable nutritional gaps. Achieving widespread immune resilience requires rejecting fear-based narratives about sun exposure, embracing supplementation when necessary, and demanding transparency from industries that prioritize profits over health.

Tap Into Nature’s Power to Beat a SILENT Epidemic

The AHA! Team — Mon, 11 Aug 2025 05:26:53 +0000

News Staff via NaturalHealth365 – High blood pressure or hypertension is one of the most highly diagnosed conditions in American adults. Building on the research of the late Michael J. Gonzalez, DSc, NMD, PhD, whose passing shocked the holistic medical field due to complications from knee surgery, we now know that natural approaches to blood pressure management can be remarkably effective. Dr. Gonzalez’s dedication to understanding the role of natural compounds in health, particularly in his comprehensive research on hypertension, has forever left an impact on the field of nutritional medicine and human health. According to research, approximately one-third of adults in the United States have hypertension. It’s no wonder that hypertensive drugs like ACE inhibitors or beta blockers are among the most highly prescribed medications. While there are many different types of blood pressure medications, all have some form of side effect that is traded off for the benefit of lowering high blood pressure. With that said, there are many natural solutions for blood pressure, and a comprehensive study aimed to determine the most effective ones. Why high blood pressure is a silent threat (and why natural solutions matter) High blood pressure is an epidemic in the United States and most Western countries. Coupled with type 2 diabetes, hypertension is the leading cause of cardiovascular disease in adults, and usually not diagnosed soon enough to prevent significant arterial damage. Unfortunately, high blood pressure has no obvious symptoms, even at ‘stage 2,’ and modern guidelines have set healthy blood pressure at or under 120/80, which most people exceed. High blood pressure medication falls into a handful of categories, but they all perform the same role of reducing hypertension. All high blood pressure medication has some manner of side effects: fatigue, headaches, dry cough, water retention, constipation, and more. If there were foods that you could eat that had a profound effect on blood pressure, however, most people would opt for that instead of medication. That was the goal of this study referenced above – to find simple natural compounds with an effect on blood pressure without the side effects of medication. The most effective natural solutions that support healthy blood pressure The study looked at 29 potential blood pressure-reducing supplements and foods. Here are 10 of the most promising: Magnesium Magnesium plays a role in proper sleep, mood regulation, bowel motility, and blood pressure regulation. While observational studies show promising results, it’s important to note that clinical trials have shown varying effects. Magnesium can be found in dark chocolate/cocoa, leafy greens, pumpkin seeds, and various other sources. It’s best to consult a holistic healthcare provider for the proper amount if supplementing. Soy isoflavones Organic, non-GMO soy is a protein-packed alternative that can be consumed as tofu in stir-fry vegetable dishes or added to miso soup. Multiple studies indicate that soy can help reduce blood pressure when eaten regularly. Although, we would strongly recommend that you find a brand that uses “filtered” water – as its main ingredient – due to the chemicals found in most sources of drinking water. Taurine Taurine is an amino acid created in necessary amounts within the human body and through ingesting fish and meat. Research shows it effectively reduces blood pressure, primarily by calming the sympathetic nervous system and enhancing the production of nitric oxide, which helps relax blood vessels. Potassium Potassium is crucial for proper cardiac function and blood vessel relaxation. It’s readily available in spinach, wild caught salmon, avocado, and bananas. However, if you’re already taking blood pressure medication, consult your doctor before increasing your potassium intake, as some medications can affect potassium levels. Pomegranate juice Research shows pomegranate juice can help reduce blood pressure through its anti-inflammatory properties and ability to increase nitric oxide production. Clinical trials have demonstrated meaningful reductions in both systolic and diastolic blood pressure with regular consumption. Melatonin Beyond its role in sleep regulation, melatonin serves as a powerful antioxidant. Studies show it can help lower blood pressure, particularly in people with disrupted sleep patterns. The research suggests this effect comes from its antioxidant properties and ability to improve sleep quality. Garlic Garlic consistently proves its worth in cardiovascular health. Research shows it can help lower blood pressure by increasing nitric oxide production and reducing smooth muscle cell proliferation in blood vessels. It’s also a potent anti-inflammatory agent, contributing to its blood pressure-lowering effects. Fish oil The omega-3 fatty acids in fish oil, particularly from fatty cold-water fish like sardines, salmon, and anchovies, show significant benefits for blood pressure. The effect is especially pronounced in people with untreated hypertension. These polyunsaturated fatty acids reduce inflammatory compounds and improve blood vessel function. European mistletoe While less common, clinical research shows that European mistletoe extract, when taken consistently for 12 weeks, can significantly reduce blood pressure in people with hypertension. However, this should only be used under professional guidance. Coenzyme Q10 (CoQ10) This naturally occurring compound, found in grass fed meat, wild caught fish, and nuts, has shown promising results in blood pressure management. Research indicates it reduces oxidative stress and improves nitric oxide availability. Tap into nature’s evidence-based solutions While blood pressure medications may (sometimes) be necessary for a short period of time, nature provides multiple solutions for this common problem. Many whole foods offer profound benefits for blood pressure management and other health advantages. If you can achieve similar results through dietary changes and targeted supplementation, it’s worth exploring these natural alternatives under proper medical supervision. The key is to work with healthcare providers who understand both conventional and natural approaches to create a comprehensive strategy for maintaining healthy blood pressure levels. Dr. Gonzalez’s research helps remind us that the most effective solutions can sometimes be found in nature when properly understood and applied. Always consult with healthcare providers before changing your blood pressure management strategy, especially if you’re currently taking medication. And, always choose organic foods (as much as possible) to avoid unwanted chemicals.

WARNING: Your Protein Powder Might be Loaded with Toxic Heavy Metals

The AHA! Team — Mon, 14 Jul 2025 05:03:04 +0000

Stephanie Woods via NaturalHealth365 – Protein supplements are a big business in the United States. In 2023, the market exceeded $9.69 billion. As more people strive to improve their health, lose weight, and get more fit, this figure is expected to continue climbing. The general consensus among consumers is that protein supplements are “natural,” and since they are typically found in health food stores and wellness sites, then they must be safe. But are they? The Clean Label Project’s Protein Category analyzed 160 products from 70 of the leading brands for protein supplements. The 2024-25 Protein Powder Category Report provides vital data regarding some concerning ingredients and potential contaminants that consumers should know before taking them. The results are eye-opening. An alarming 47% of the products tested exceeded the toxic metal safety threshold set forth by California Proposition 65. In simple terms, most of the protein supplements tested were potentially unsafe. Understanding proposition 65: Context for the findings To put the findings in context, you have to understand Proposition 65. This California law has a list of chemicals maintained by the state. These chemicals are believed to cause reproductive harm or cancer in humans. Businesses must place warning labels on foods containing these chemicals at levels that exceed the “safe” levels set forth by the law. The Proposition 65 list contains many synthetic and natural chemicals commonly found as ingredients or additives in solvents, dyes, household products, pesticides, drugs, and food. These chemicals may be used in manufacturing or as a byproduct of a chemical process, such as fumes or exhaust. Key findings from the study The study tested 160 products from 70 popular brands for 258 heavy metals and chemicals, focusing on heavy metals and bisphenols. The analysis yielded a total of 35,863 findings. 47% of all tested products exceeded state or federal safety regulations, including Proposition 65. 21% of all products contained more than double the acceptable levels of lead as defined by Proposition 65. Organic protein powders: 79% exceeded Proposition 65 levels for lead. 41% contained over twice the acceptable levels of lead. Plant-based protein powders: 77% exceeded Proposition 65 levels for lead. Whey protein powders: 28% exceeded Proposition 65 levels for lead. Collagen protein powders: 26% exceeded Proposition 65 levels for lead. Chocolate protein powders: 65% exceeded Proposition 65 levels for lead. 29% contained over twice the acceptable levels of lead. These findings highlight significant safety concerns regarding heavy metal contamination in protein powders, particularly in organic, plant-based, and chocolate varieties. What should you look for in a protein powder? The analysis revealed that plant-based protein powders had the highest levels of contaminants, while whey-based protein powders showed the lowest levels. If you’re looking for a safer option, choosing a product with minimal contaminants is key. For added peace of mind, consider buying from Clean Label Project Certified companies. Some trusted brands include: Genetic Nutrition Gorilla Formula 23 Nutrabox Oziva Puori Ritual Wellbeing Nutrition Wicked Protein You can also visit the Clean Label Project website to learn about more certified products and make informed health choices. Editor’s note: I highly recommend LuvByNature Grazing Goat Whey Protein – which comes from goats that graze – 365 days per year – on pesticide and chemical free pastures. No hormones, antibiotics or pesticides are used – ever. This product is non-GMO and gluten free.

Spirulina Protects Against Chronic Conditions, Scientists Reveal

The AHA! Team — Mon, 17 Mar 2025 05:30:10 +0000

Lori Alton via NaturalHealth365 – According to a new review published in the Journal of Dietary Supplements, spirulina can alleviate risk factors for heart disease. Let’s take a closer look at the outsized benefits of this tiny microbe. Retirement is supposed to be a time of relaxation and reward, in which people finally have the leisure and the means to pursue their favorite activities. But for many, the luster of these “golden years” is dimmed by poor health. The sad fact is that two out of every three Americans over the age of 60 are affected by chronic conditions such as heart disease, type 2 diabetes, and cancer. It turns out that spirulina, a single-celled blue-green algae, may potentially help protect against these conditions. Holistic doctors and researchers increasingly report that wise lifestyle choices (such as getting proper nutrition, appropriate supplementation, sufficient exercise, and restful sleep) can play a major role in preventing these potentially life-threatening ailments. And ongoing research continues to confirm this. According to a new review published in the Journal of Dietary Supplements, spirulina can alleviate risk factors for heart disease. Let’s take a closer look at the outsized benefits of this tiny microbe. Spirulina supplementation can help prevent cardiometabolic diseases The review focused on spirulina’s effects on risk factors for cardiometabolic diseases – a group of conditions that encompasses heart failure, heart attacks, strokes, type 2 diabetes, and nonalcoholic fatty liver disease. Since obesity, inflammation, abnormal cholesterol profiles, and imbalanced blood sugar can all “set the stage” for cardiometabolic diseases, researchers were eager to see if spirulina supplementation could ease these risk factors. The short answer to this question is an emphatic “yes.” Extensive studies cited in the review revealed that spirulina supplementation reduced body weight and waist circumference while lowering levels of inflammatory markers, triglycerides, and harmful LDL cholesterol. In addition, spirulina caused a beneficial increase in insulin sensitivity, leading to lower levels of both fasting and after-meal blood sugar. Impressed researchers declared the supplement “effective in reducing multiple risk factors for heart disease” and praised it as a “promising dietary intervention” with “consistent” benefits. Additional research supports spirulina’s anti-obesity effects In a 2017 double-blind, placebo-controlled clinical trial published in BMC Complementary and Alternative Medicine, obese participants who were given a gram of spirulina a day for twelve weeks significantly reduced their body mass and weight. In a separate study, two grams of spirulina powder a day for 12 weeks also reduced appetite, weight, and waist circumference. Multiple studies have also shown that spirulina suppresses pro-inflammatory cytokines and boosts important antioxidants such as glutathione and superoxide dismutase, helping ease oxidative stress and inflammation. Incidentally, spirulina can help prevent fat deposits in the liver, making it a valuable addition to your toolbox of natural nutrients to use against nonalcoholic fatty liver disease. This nutritious algae is packed with antioxidants, essential minerals, vitamins, and high-quality protein Spirulina’s “secret weapon” in supporting health appears to be a natural plant pigment known as phycocyanin. This compound – responsible for the algae’s eye-catching blue-green color – suppresses oxidative stress in fat cells, discouraging inflammation and enhancing the body’s sensitivity to insulin. Phycocyanin also increases cholesterol excretion – and gets a “helping hand” in this task from spirulina’s high levels of gamma-linolenic acid (GLA). This essential fatty acid has also been shown to regulate cholesterol levels. However, phycocyanin shouldn’t get all the credit for this algae’s health benefits. Spirulina contains many heart-protective polyphenols – such as resveratrol and quercetin – also found in apples, grapes, and onions. Finally, spirulina has an outstanding nutritional pedigree. In addition to being low in fat and calories (and comprised of 70 percent high-quality protein), spirulina contributes healthy amounts of zinc – necessary for proper immune function – along with magnesium and potassium, both needed to regulate heartbeat and blood pressure. While spirulina has played an important role in human diets worldwide since antiquity, its reputation as a “superfood” received a 20th-century boost when it was recommended by NASA as a food for astronauts on prolonged space voyages. By the way, spirulina is also believed to modulate the immune system and boost athletic performance and stamina. Aficionados claim that yet another of its “superpowers” is the ability to reduce the sneezing, itching, and congestion of hay fever (allergic rhinitis). Sprinkle on the spirulina powder and optimize your health Spirulina is available as a supplement in liquid extracts, powders, capsules, and tablets. Holistic healthcare providers typically recommend amounts from one to eight grams daily, but consult your holistic physician before adding spirulina to your health routine. Always use a high-quality product from a reputable vendor to avoid contamination with heavy metals and pollutants. Spirulina powder can be sprinkled over salads, added to soups, dips, baked goods, or mixed into your favorite smoothie or protein shake. As the new review suggests, spirulina seems custom-designed to support health and well-being. While the idea of consuming powdered algae may seem initially unappealing, learning about the potential health benefits may help change your reaction from an automatic “Yuck!” to an enthusiastic “Yay!” Sources for this article include: Tandfonline.com NIH.gov Springer.com Lifenotlabs.com Tandfonline.com To read the original article click here.

Bone Fractures, Lung Cancer, and Vitamin B12 Supplements?

The AHA! Team — Fri, 14 Feb 2025 06:21:08 +0000

Michael Greger M.D. FACLM via Nutrition Facts – What do randomized controlled trials of high-dose daily vitamin B12 supplementation show about its effects on cancer risk, death, and longevity? In 2019, “Association of High Intakes of Vitamins B6 and B12 from Food and Supplements with Risk of Hip Fracture Among Postmenopausal Women in the [Harvard] Nurses’ Health Study” was published. Note, though, that only the combined high intake of vitamins B6 (≥35 mg/day) and B12 (≥20 mcg/day) was associated with an increased hip fracture risk. We know that treatment with high doses of vitamin B6 may increase hip fracture risk on its own. After a decade or so, those who had been taking high-dose (40 mg) B6 supplements had about a 40 percent higher hip fracture risk, but not those taking B12, as you can see below and at 0:35 in my video Do Vitamin B12 Supplements Cause Bone Fractures and Lung Cancer?. That’s what the Harvard study found, too. High intake of vitamin B12 alone was not associated with increased risk. In fact, some observational studies suggest a slightly lower fracture risk at high B12 blood levels. What we care about most, though, are interventional studies, where people are randomized to B12 so we can see what happens, and when we look at those, we find there is no increased fracture risk among those given B12. In conclusion, based on randomized controlled trials, high doses of vitamin B12 have not been shown to be associated with the risk of fractures. Okay, but what about this? In 2017, a study found that men taking vitamin B12 supplements appeared to have increased lung cancer risk. Now, the researchers didn’t find any such association in women, and the increased risk was mostly among men who smoked. Could it be that B12 was feeding budding tumors? It’s hard enough imagining a vitamin being carcinogenic on its own, especially if it somehow only affects men and not also women. “Replication of these ﬁndings in additional prospective studies with careful measurement of B vitamin supplement use is warranted.” And, indeed, when you put together all the observational studies, there is no signiﬁcant correlation between lung cancer and levels of B12 in the blood, whether you’ve smoked or not. If anything, most studies seemed to trend towards higher B12 levels being protective, as you can see below and at 2:03 in my video. Then, in 2018, a new study found an association between overall lung cancer risk and higher circulating levels of B12, again appearing to be more of a concern with smokers, as seen here and at 2:16 in my video. Now, this was another observational study. Those with higher B12 levels were just observed to have higher cancer levels. Those of you who have been following my work know the drill: There are two potential issues that arise in observational studies that prevent us from ascribing cause-and-effect: confounding factors, also known as “lurker variables,” and reverse causation. What might be a lurker variable in this case? What might be a third factor associated with both higher B12 levels and cancer that may be the true cause? Well, who has higher levels of B12 circulating in their blood? Those who eat a lot of meat and dairy, which are, in fact, “the most important contributors to serum vitamin B-12,” that is, B12 in our blood. And those who eat more meat do tend to have more lung cancer: “Dose-response analysis showed that consumption of red meat for 120 g per day might increase the risk of lung cancer by 35%, and consumption of processed meat for 50 g per day might increase the risk of lung cancer by 20%.” So, we’re generally talking about 35 percent more risk for every quarter-pound burger eaten each day and about 20 percent increased risk for every breakfast sausage link. It’s no wonder those with higher B12 levels in their blood could have more lung cancer. The B12 could just be a marker for meat intake. And, if you remember, reverse causation is when X may not lead to Y, but, instead, Y may lead to X. So, instead of high B12 blood levels leading to cancer, maybe cancer leads to high blood levels of B12. And, indeed, nearly 75 percent of patients diagnosed with cancer exhibit elevated B12 levels. So, elevated B12 levels may simply be a marker for cancer. Besides taking extra B12, there are all sorts of reasons your levels can rise, such as liver problems, kidney problems, bone marrow problems, and cancer, as you can see below and at 3:50 in my video. So, high B12 levels may just be a marker of brewing, but not yet diagnosed, cancer. What about observational studies specifically linking B12 supplement use to lung cancer, though? Those could also be reverse causation: “The consequence of being at risk for cancer is that patients will engage in healthier behaviors, including taking multivitamins (reverse causality). The well-established causes, such as smoking, chronic obstructive pulmonary disease, and previous cancers, are the real lung cancer risks.” So, we’re left with this “chicken or the egg causality dilemma,” which is why, ideally, we need randomized controlled trials to see if there’s any cause and effect. This became even more urgent with genetic evidence suggesting that those born with higher lifelong levels may be at increased risk. Thankfully, as you can see below and at 4:47 in my video, we do have randomized controlled trials—more than a dozen randomized controlled trials randomizing thousands of people up to 2,000 micrograms of B12 every single day for years, in fact. The findings? “Vitamin B supplementation does not have an effect on cancer incidence, death due to cancer, or total mortality.” And this includes specifically looking at lung cancer, as seen below and at 5:02 in my video. In fact, if anything, vitamin B supplements may actually lower the risk of the most dangerous form of skin cancer. If you missed my previous video, check out Do Vitamin B12 Supplements Cause Acne?. For my other B12 updates, see related posts below. All of these videos can be found in one digital download: Latest Vitamin B12 Recommendations. I’ve also explored vitamin B12’s role in stroke risk. See the related posts below. That series is available for digital download, too: Why Do Vegetarians Have Higher Stroke Risk?. Key Takeaways High intakes of vitamins B6 and B12 together are associated with an increased risk of hip fractures in postmenopausal women, but high B12 alone does not increase this risk. High doses of vitamin B12, based on randomized controlled trials, have not been shown to increase the risk of fractures, unlike high doses of vitamin B6. Some studies suggest that B12 supplementation may be linked to an increased risk of lung cancer in men, particularly smokers, though this association has not been consistently observed. Higher B12 levels in observational studies might be linked to higher meat consumption, which could be the true cause of increased cancer risk, rather than B12 itself. Elevated B12 levels may indicate underlying health issues like cancer, rather than being a direct cause of cancer, highlighting the importance of distinguishing between correlation and causation.

Sara Middleton via NaturalHealth365 – Are you or someone you love one of the 300+ million people living with an anxiety disorder? If you are, we don’t blame you for being frustrated by conventional treatment options. Anti-anxiety drugs and antidepressants come with unpleasant side effects like weight gain, fatigue, and restlessness. So, if you’ve wondered if you’ll ever find a natural solution for your mental health trouble, you may want to start with magnesium. A 2024 study published in Current Pharmaceutical Design examined magnesium’s mental health benefits, focusing on its effects on anxiety. The researchers found that magnesium plays a crucial role in easing anxious thoughts and feelings by participating in key enzymatic reactions that stabilize neurotransmitters and aid in their release. In an earlier study, a team of researchers conducted a randomized controlled trial on the effects of magnesium supplementation for depression. Let’s take a look at what these scientists found. Magnesium supplementation improves quality of life in people with anxiety, study reveals In their study, the researchers recruited 126 adults from an outpatient clinic and randomly assigned them to a control group or a group that received magnesium supplements. After 6 weeks, the researchers discovered that daily magnesium supplementation improved depression and quality of life. “Similar effects,” the authors say in their conclusion, “were observed regardless of age, gender, baseline severity of depression, baseline magnesium level, or use of antidepressant treatments.” Incredibly, these positive effects were seen within as little as two weeks. Compare this to antidepressants, which typically take up to 2 to 3 months to start having any impact – if at all, since they don’t work for everyone. It’s not hard to imagine how magnesium may prove to be an effective natural solution for anxiety. For one thing, this essential mineral is involved in hundreds of physiological processes within the body – including those involving hormone function and regulation. Plus, other studies indicate that magnesium deficiencies are associated with an increased risk for depression, so it makes sense that by correcting a deficiency, a person may resolve or drastically improve their depressive or anxious symptoms. Amazingly, at least 50 percent of all Americans are magnesium deficient anyway! It’s time that more doctors and psychiatrists talk to their patients about natural options for their mental health issues, in addition to or even instead of toxic and conventional medications. Here’s how much magnesium you need and where to get it in your diet The authors of this study gave the experimental group 248 mg of magnesium per day in an over-the-counter supplement form. This is actually a conservative amount, at least according to the National Institutes of Health’s Office of Dietary Supplements. Generally, men and women are recommended to consume around 400 to 420 mg and 310 to 320 mg daily (respectively). Magnesium is safe and well-tolerated, but if you take too much too quickly, you may experience things like stomach upset and diarrhea. So, introduce your natural supplement slowly, and in the meantime, be sure to consume magnesium-rich foods like organic avocados, nuts and seeds, salmon, legumes, and dark chocolate.

New Study Reveals Declining Nutrient Intake Among U.S. Women of Reproductive Age

The AHA! Team — Wed, 20 Nov 2024 06:42:21 +0000

Pooja Toshniwal Paharia via News-Medical – Groundbreaking study reveals how chromatin and DNA methylation changes during brain development contribute to the risk of neuropsychiatric disorders like schizophrenia and bipolar disorder. A recent study published in JAMA Network Open compares trends in nutrient consumption from dietary sources and supplements in pregnant and non-pregnant women in the United States. The impact of nutrient deficiencies during pregnancy Nutritional status is crucial for maternal health and fetal growth, as it reduces the risk of chronic diseases in later life. Energy requirements are greater during pregnancy due to increased metabolic processes and workload on the lungs and the heart. During pregnancy, women require multiple nutrients, including protein for tissue growth, iron to produce red blood cells, folate to prevent neural disorders, calcium to develop strong fetal bones, and iodine for increased thyroxine secretion. Several studies have reported inadequate nutrient intake among pregnant women in the United States, with a high prevalence of magnesium, vitamin D, and vitamin E deficiencies. Pregnant women also consume less potassium, choline, and vitamin K, despite higher rates of nutrient supplementation than non-pregnant women. Furthermore, most pregnant women consume eicosapentaenoic acid (EHA) and docosahexaenoic acid (DHA) below the recommended threshold for optimal health. About the study The current study, which was conducted between February 2022 and July 2024, included 1,392 pregnant and 9,737 non-pregnant women between 20 and 44 years of age. Data were obtained from at-home interviews and visits to mobile examination centers. Study participants provided one or more 24-hour dietary recalls at mobile examination centers, followed by telephonic conversations. The study participants also provided information on their age, race, ethnicity, education, smoking status, and income-to-poverty ratio (PIR). Pregnancy status was determined from positive urine pregnancy tests and self-reported trimester. The primary study measures included the average regular consumption of micronutrients and macronutrients, as well as the prevalence of micronutrient intake insufficiency. The U.S. Food Security Survey Module was utilized to assess adult food security. Participant enrollment in the Food Stamps, Supplemental Nutrition Assistance Program (SNAP), and Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) was also recorded. Program enrollment was based on benefits received in the previous year. Data were also analyzed from ten National Health and Nutrition Examination Surveys (NHANES) cycles between 1999 and 2018. The National Cancer Institute (NCI) approach and linear regressions enabled the analysis, whereas the Simulating Intake of Micronutrients for Policy Learning and Engagement (SIMPLE) tool evaluated nutrient intake. Trends in supplement use and dietary intake The mean age of pregnant and non-pregnant women was 29 and 32 years, respectively. Among pregnant women, 27% and 34% were in their first and second trimesters, respectively. Dietary supplement use was significantly higher among pregnant women than non-pregnant women at 78% and 46%, respectively. The mean carbohydrate consumption reduced from 307 g/day during 1999-2000 to 275 g/day during 2013-2018 among pregnant women. Among non-pregnant women, carbohydrate intake reduced from 252 g/day to 217 g/day from 1999-2000 to 2017-2018. Between 1999-2000 and 2013-2018, an 11 percent point (pp) increase was observed in pregnant women who consumed below the Estimated Average Requirement (EAR) of vitamin A. The percentage of pregnant women who consumed below-EAR vitamin C also increased by 8.9 pp. Likewise, the percentages of non-pregnant women with insufficient consumption of vitamin A, vitamin C, and iron increased by 20, 11, and five pp, respectively, from 1999-2000 to 2017-2018. The average calcium consumption increased from 1,121 mg/day to 1,309 mg/day for pregnant women and from 850 mg/day to 981 mg/day for non-pregnant women. Among pregnant women, prevalence rates for insufficient intake were reduced by 16 pp for magnesium and 33 pp for vitamin K. Among non-pregnant women, insufficient consumption reduced by 16 pp of calcium, 16 pp of magnesium, and 33 pp of vitamin K. Pregnant women primarily reduced their carbohydrate intake from added sugars, fortified flour, and cereals. Health professionals advise limiting sugar intake; however, reducing fortified flour and cereal consumption could reduce the intake of vitamins A, C, magnesium, iron, and folate. Decreased use of supplements due to side effects like nausea and constipation could further reduce iron intake. Furthermore, reduced vitamin C intake may exacerbate iron inadequacy. Conclusions Carbohydrate, vitamin A, vitamin C, and iron intake has reduced in the past two decades among pregnant and non-pregnant women in the U.S. The nutrient gaps identified in the present study could inform regulatory, healthcare, and scientific communities to formulate policies and guidelines to improve nutrient intake by reproductive-age women in the U.S..

Little-Known Berry Shows Promise for Eye Health and Beyond

The AHA! Team — Mon, 07 Oct 2024 08:17:29 +0000

Patrick Tims via NaturalHealth365 – Nestled in the forests of Europe and North America lies a tiny berry with outsized health benefits. The bilberry, a close cousin of the blueberry, is emerging as a nutritional powerhouse that could revolutionize our approach to wellness and disease prevention. Often overlooked in favor of more common foods, this small, dark fruit packs a powerful punch when it comes to health benefits. Recent studies have uncovered a treasure trove of potential advantages, from boosting metabolism to safeguarding vision and even combating chronic diseases. Promising research: Bilberry extract and fish oil for severe dry eye relief This study investigated the effects of a dietary supplement containing bilberry extract and fish oil on severe dry eye symptoms. The research involved 24 subjects with severe dry eye symptoms, split evenly into intervention and control groups. The intervention group took a daily supplement containing 600 mg bilberry extract and 240 mg DHA-refined fish oil for 3 months, while the control group did not take any supplements. The study used several measurements to assess eye health: The Ocular Surface Disease Index (OSDI) score: A questionnaire that measures how much discomfort a person experiences from dry eyes. Non-invasive tear break-up time (NITBUT): A test that shows how quickly the tear film on the eye’s surface starts to break up, indicating how stable and effective the tears are. Phenol red thread test (PRT): A simple way to measure how much moisture the eye produces. Percentage of meibomian gland openings: This checks the health of glands that produce oils essential for preventing tear evaporation. These tests together provide a comprehensive picture of eye health and the severity of dry eye symptoms. After 3 months, the intervention group showed improvements in all outcome measures. Compared to the control group, there were significant improvements in OSDI score, NITBUT, and PRT. Notably, these improvements were consistent across different age groups, including both younger adults and middle-aged participants. The study suggests that dietary supplementation with bilberry extract and fish oil may improve both signs and symptoms of severe dry eyes, regardless of age. From eye health to cancer prevention The benefits of bilberries extend far beyond eye health. Emerging research indicates that these potent berries may play a role in supporting overall cardiovascular health. Some studies have shown that bilberry consumption may help decrease cholesterol levels, particularly LDL cholesterol, while increasing HDL cholesterol. This effect, combined with the berries’ potential to improve blood vessel function, makes them a promising natural ally in the fight against heart disease. Furthermore, bilberries show promise in blood sugar management, making them of particular interest to those at risk of or living with diabetes. The berries appear to have a positive effect on insulin sensitivity and glucose metabolism, potentially helping to regulate blood sugar levels and reduce the risk of type 2 diabetes. Bilberries’ anti-inflammatory properties also make them a subject of interest in cognitive health research. Some scientists believe that regular consumption of these berries might help protect against age-related cognitive decline and neurodegenerative diseases like Alzheimer’s, though more research is needed in this area. As if these benefits weren’t enough, bilberries are also being studied for their potential anti-cancer properties. The high levels of antioxidants in these berries may help protect cells from damage that can lead to cancer, and some laboratory studies have shown promising results in inhibiting the growth of cancer cells. While more research is needed to fully understand the extent of bilberries’ health benefits, the existing evidence paints a picture of a truly remarkable fruit. From supporting eye health to potentially fighting chronic diseases, these tiny berries pack a powerful punch when it comes to promoting overall wellness. As research continues, it’s likely that we’ll uncover even more reasons to add this superfruit to our diets. Harness the power of bilberries in your diet Incorporating bilberries into your diet can be both easy and delicious: Brew bilberry tea for a traditional remedy Add fresh or frozen bilberries to smoothies Consume bilberry extract supplements Enjoy handfuls of whole bilberries as a snack Whether you opt for fresh berries, supplements, or extracts, adding bilberries to your diet could be a simple yet powerful step towards better health. As always, consult with a holistic healthcare professional before starting any new supplement routine, especially if you have existing health conditions or are taking medications.
