Read all latest medical research on vitamins and minerals. en-us Sun, 09 Aug 2026 08:49:10 EDT Sun, 09 Aug 2026 08:49:10 EDT 60 https://www.sciencedaily.com/images/scidaily-logo-rss.png https://www.sciencedaily.com/news/health_medicine/vitamins/ For more science news, visit ScienceDaily. https://www.sciencedaily.com/releases/2026/08/260806050717.htm Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more like an experimental cancer drug than an ordinary supplement. Early studies suggest it may damage vulnerable cancer cells, reduce treatment side effects, and possibly improve outcomes for some patients.

Ferulic acid suppressed contractions triggered by several chemical messengers in laboratory experiments. The discovery could eventually support new dietary approaches for diarrhea-related digestive disorders, although it may make constipation worse.

The SPF 30 formula could make sunscreen easier and more appealing to use across a wider range of skin tones. Sun, 19 Jul 2026 23:32:12 EDT https://www.sciencedaily.com/releases/2026/07/260718010200.htm https://www.sciencedaily.com/releases/2026/06/260624025511.htm Osteopenia is a common but often overlooked condition that causes bones to become less dense and more fragile. Because it develops silently, many people only discover they have it after a fracture or bone scan. Aging, menopause, poor diet, and inactivity can all contribute to bone loss. Fortunately, exercise, adequate calcium and vitamin D, and other healthy habits can slow or even partially reverse the decline. Thu, 25 Jun 2026 00:25:26 EDT https://www.sciencedaily.com/releases/2026/06/260624025511.htm https://www.sciencedaily.com/releases/2026/06/260623083116.htm Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy. The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago. Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly. This could explain why some people experience fatigue and brain fog even before traditional signs of deficiency show up. Thu, 25 Jun 2026 10:57:39 EDT https://www.sciencedaily.com/releases/2026/06/260623083116.htm https://www.sciencedaily.com/releases/2026/06/260623083104.htm A study of nearly 300 people across northern Britain found that vitamin D levels often stay low all year in groups most at risk. Surprisingly, summer sunshine did not significantly boost vitamin D levels among older adults or people from minoritized ethnic backgrounds. Wed, 24 Jun 2026 00:45:50 EDT https://www.sciencedaily.com/releases/2026/06/260623083104.htm https://www.sciencedaily.com/releases/2026/06/260622014313.htm A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected. Mon, 22 Jun 2026 08:23:53 EDT https://www.sciencedaily.com/releases/2026/06/260622014313.htm https://www.sciencedaily.com/releases/2026/06/260621060318.htm Not all fats affect your body the same way. Researchers found that palmitic acid, a saturated fat common in many foods, may contribute to insulin resistance and type 2 diabetes by triggering inflammation, toxic fat buildup, and cellular stress. In contrast, oleic acid—the heart-healthy fat abundant in olive oil—appears to help protect insulin function and may even counter some of the harmful effects of palmitic acid. Sun, 21 Jun 2026 20:25:04 EDT https://www.sciencedaily.com/releases/2026/06/260621060318.htm https://www.sciencedaily.com/releases/2026/06/260614011852.htm For years, calcium and vitamin D supplements have been promoted as a simple way for older adults to protect their bones and prevent falls. But a massive review of nearly 154,000 people found that calcium, vitamin D, or a combination of both provided little to no meaningful protection against fractures or falls for most older adults. Mon, 15 Jun 2026 08:44:53 EDT https://www.sciencedaily.com/releases/2026/06/260614011852.htm https://www.sciencedaily.com/releases/2026/06/260606075852.htm A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a lower risk of developing dementia, while higher nitrate and nitrite intake from red meat, processed meat, and even drinking water was linked to a greater risk. Mon, 08 Jun 2026 01:07:34 EDT https://www.sciencedaily.com/releases/2026/06/260606075852.htm https://www.sciencedaily.com/releases/2026/06/260605023408.htm Supplements are often marketed as shortcuts to better health, but for many older adults, the real issue is whether they have a specific deficiency. Vitamins like B12 and D can play an important role when levels are low, while protein may be one of the most overlooked nutrients for maintaining strength and independence. More isn’t always better, though—some supplements can cause harm or interact with medications. Sat, 06 Jun 2026 08:40:28 EDT https://www.sciencedaily.com/releases/2026/06/260605023408.htm https://www.sciencedaily.com/releases/2026/05/260528082501.htm Feeling constantly drained might not just be about poor sleep or working too hard. Researchers in Japan found that low levels of key vitamins — especially vitamin B12 and folate — may quietly contribute to fatigue and lack of motivation, even in otherwise healthy people. Thu, 28 May 2026 23:23:48 EDT https://www.sciencedaily.com/releases/2026/05/260528082501.htm https://www.sciencedaily.com/releases/2026/05/260527023200.htm Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice — especially with iron supplements — experienced noticeable increases in hemoglobin levels. Since guava contains far more vitamin C than oranges, scientists believe it could become a simple, affordable nutrition tool in regions where anemia is widespread. Wed, 27 May 2026 03:09:36 EDT https://www.sciencedaily.com/releases/2026/05/260527023200.htm https://www.sciencedaily.com/releases/2026/05/260526233433.htm Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. By combining vitamin K with components related to vitamin A, the researchers developed compounds that were about three times more effective at turning neural stem cells into neurons than natural vitamin K alone. Wed, 27 May 2026 00:02:46 EDT https://www.sciencedaily.com/releases/2026/05/260526233433.htm https://www.sciencedaily.com/releases/2026/05/260526022009.htm Vitamin B12 has long been seen as a health hero, helping the body make red blood cells, repair DNA, and keep nerves functioning properly. But scientists are discovering that the story may be more complicated than simply “more is better.” While too little B12 can damage DNA and raise cancer risk, some studies suggest that extremely high levels — especially from long-term high-dose supplements — may also be linked to certain cancers or poorer outcomes in cancer patients. Wed, 27 May 2026 00:52:06 EDT https://www.sciencedaily.com/releases/2026/05/260526022009.htm https://www.sciencedaily.com/releases/2026/05/260523021820.htm A surprising study suggests vitamin D2 supplements may reduce the body’s levels of vitamin D3 — the more effective form of vitamin D. Researchers found D3 not only boosts vitamin D status more efficiently, but may also play a unique role in helping the immune system fight off viruses and bacteria. The discovery is prompting scientists to rethink whether D3 should become the preferred choice for supplementation. Sat, 23 May 2026 10:38:26 EDT https://www.sciencedaily.com/releases/2026/05/260523021820.htm https://www.sciencedaily.com/releases/2026/05/260522031001.htm Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain. Researchers at UC San Francisco found that older adults with “normal” but lower levels of active B12 showed signs of slower thinking, delayed visual processing, and more damage to the brain’s white matter — the communication highways that help different brain regions work together. Fri, 22 May 2026 08:33:40 EDT https://www.sciencedaily.com/releases/2026/05/260522031001.htm https://www.sciencedaily.com/releases/2026/05/260519224308.htm Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up using significantly more opioid medication to cope. Researchers say vitamin D may help regulate how the body processes pain through its effects on inflammation and the immune system. Tue, 19 May 2026 23:30:39 EDT https://www.sciencedaily.com/releases/2026/05/260519224308.htm https://www.sciencedaily.com/releases/2026/05/260517030515.htm Studies suggest watermelon could be a hidden powerhouse for better health. Researchers found that people who eat watermelon tend to have higher-quality diets packed with more vitamins, fiber, and antioxidants — while consuming less added sugar and saturated fat. Another study showed watermelon juice may help protect blood vessel function and support heart health. Sun, 17 May 2026 08:56:21 EDT https://www.sciencedaily.com/releases/2026/05/260517030515.htm https://www.sciencedaily.com/releases/2026/05/260515002158.htm Scientists have uncovered a surprising dark side to vitamin B2: it may help cancer cells stay alive. The vitamin supports a cellular shield that protects tumors from ferroptosis, a form of programmed cell death linked to cancer suppression. In lab tests, researchers used a vitamin B2-like compound called roseoflavin to break down that protection and trigger cancer cell death. Fri, 15 May 2026 07:44:45 EDT https://www.sciencedaily.com/releases/2026/05/260515002158.htm https://www.sciencedaily.com/releases/2026/05/260506225551.htm Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good. While biotin is often marketed for stronger hair and nails, there’s little evidence it actually helps cancer-related hair loss—and it can dangerously interfere with lab tests. Doctors say the supplement can distort key blood markers, potentially masking cancer recurrence or delaying treatment decisions. Thu, 07 May 2026 22:07:42 EDT https://www.sciencedaily.com/releases/2026/05/260506225551.htm https://www.sciencedaily.com/releases/2026/04/260428004119.htm A daily vitamin D supplement may quietly supercharge chemotherapy. In a small study, women who took low doses alongside treatment were far more likely to see their cancer vanish than those who didn’t. Since vitamin D also supports immune function—and many patients are deficient—it could be playing a bigger role than expected. Scientists say this affordable approach deserves much deeper investigation. Tue, 28 Apr 2026 01:03:03 EDT https://www.sciencedaily.com/releases/2026/04/260428004119.htm https://www.sciencedaily.com/releases/2026/04/260420014744.htm Cancer cells are known for their “glutamine addiction,” but many can escape this weakness by switching to alternative fuels. Researchers found that vitamin B7 acts like a metabolic “license,” enabling this escape route through a key enzyme. Without biotin, cancer cells lose that flexibility and stop growing. Mutations in a cancer-linked gene can make this vulnerability even stronger, offering a promising new target for therapy. Mon, 20 Apr 2026 07:14:27 EDT https://www.sciencedaily.com/releases/2026/04/260420014744.htm https://www.sciencedaily.com/releases/2026/04/260411081426.htm Scientists have achieved the unthinkable by stabilizing a highly reactive molecule in water, confirming a decades-old theory about vitamin B1’s role in the body. The breakthrough not only solves a scientific mystery but could revolutionize greener chemical manufacturing. Sat, 11 Apr 2026 08:33:37 EDT https://www.sciencedaily.com/releases/2026/04/260411081426.htm https://www.sciencedaily.com/releases/2026/03/260326075552.htm A new study reveals that high doses of antioxidants—often seen as harmless or beneficial—may actually impact future generations. Male mice given common supplements like NAC produced offspring with subtle but significant facial and skull changes. Researchers believe this is tied to altered sperm DNA, even though the fathers showed no outward health issues. Fri, 27 Mar 2026 08:41:19 EDT https://www.sciencedaily.com/releases/2026/03/260326075552.htm https://www.sciencedaily.com/releases/2026/03/260324080203.htm Researchers have identified microRNA-93 as a key genetic driver of fatty liver disease and discovered that vitamin B3 can effectively shut it down. This finding suggests a safe, widely available vitamin could become a powerful new treatment. Tue, 24 Mar 2026 08:09:15 EDT https://www.sciencedaily.com/releases/2026/03/260324080203.htm https://www.sciencedaily.com/releases/2026/03/260309225222.htm Colorblindness may be doing more than making traffic lights confusing — it could also be hiding a life-threatening warning sign. Researchers analyzing millions of medical records found that people with bladder cancer who are also colorblind have a 52% higher mortality rate over 20 years compared to those with normal vision. The likely reason: many people with color vision deficiency struggle to see red, making it harder to notice blood in urine, the most common early sign of bladder cancer.

A new study found that extended use disrupted iron and calcium levels in rats, changes associated with anemia and osteoporosis risk. Researchers also observed shifts in mineral balance across multiple organs. Experts say the medications are effective, but prolonged use without medical guidance could have unintended consequences. Thu, 26 Feb 2026 07:27:39 EST https://www.sciencedaily.com/releases/2026/02/260225081159.htm https://www.sciencedaily.com/releases/2026/02/260217005756.htm Researchers investigating crops grown in soil contaminated by the 2015 mining disaster in Brazil discovered that toxic metals are moving from the earth into edible plants. Bananas, cassava, and cocoa were found to absorb elements like lead and cadmium, with bananas showing a potential health risk for children under six. Although adults face lower immediate danger, scientists warn that long-term exposure could carry cumulative health consequences. Tue, 17 Feb 2026 07:07:09 EST https://www.sciencedaily.com/releases/2026/02/260217005756.htm https://www.sciencedaily.com/releases/2026/02/260204121547.htm People who switch to a fully unprocessed diet don’t just eat differently—they eat smarter. Research from the University of Bristol shows that when people avoid ultra-processed foods, they naturally pile their plates with fruits and vegetables, eating over 50% more food by weight while still consuming hundreds fewer calories each day. This happens because whole foods trigger a kind of built-in “nutritional intelligence,” nudging people toward nutrient-rich, lower-calorie options. Thu, 05 Feb 2026 10:04:34 EST https://www.sciencedaily.com/releases/2026/02/260204121547.htm https://www.sciencedaily.com/releases/2026/02/260203030551.htm Popular weight-loss drugs like Ozempic and Wegovy can dramatically curb appetite, but experts warn many users are flying blind when it comes to nutrition. New research suggests people taking these medications may not be getting enough guidance on protein, vitamins, and overall diet quality, increasing the risk of muscle loss and nutrient deficiencies. Wed, 04 Feb 2026 10:43:08 EST https://www.sciencedaily.com/releases/2026/02/260203030551.htm https://www.sciencedaily.com/releases/2026/02/260203030540.htm A massive Swedish study tracking nearly 28,000 people for 25 years found an unexpected link between full-fat dairy and brain health. Among adults without a genetic risk for Alzheimer’s, eating more full-fat cheese was associated with a noticeably lower risk of developing the disease, while higher cream intake was tied to reduced dementia risk overall. The findings challenge decades of low-fat dietary advice but come with important caveats. Wed, 04 Feb 2026 09:44:17 EST https://www.sciencedaily.com/releases/2026/02/260203030540.htm https://www.sciencedaily.com/releases/2026/01/260129080443.htm Collagen pills sound like a shortcut to younger skin, but solid evidence doesn’t back them up. Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead. Thu, 29 Jan 2026 23:30:21 EST https://www.sciencedaily.com/releases/2026/01/260129080443.htm https://www.sciencedaily.com/releases/2026/01/260127010154.htm A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives—commonly found in processed foods and drinks—is linked to a modestly higher cancer risk. While many preservatives showed no association, several widely used ones, including potassium sorbate, sulfites, sodium nitrite, and potassium nitrate, were tied to increased risks of overall cancer and specific types such as breast and prostate cancer.

They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and revealing new ones. The biggest surprise was a strong connection to vitamin B1, a common nutrient not usually linked to digestion. Thu, 22 Jan 2026 07:53:07 EST https://www.sciencedaily.com/releases/2026/01/260122074659.htm https://www.sciencedaily.com/releases/2026/01/260120015650.htm Scientists have uncovered a surprising reason why some chronic wounds refuse to heal, even when treated with antibiotics. A common bacterium found in long-lasting wounds does not just resist drugs. It actively releases damaging molecules that overwhelm skin cells and stop them from repairing tissue. Researchers discovered that neutralizing these harmful molecules with antioxidants allows skin cells to recover and restart healing. Tue, 20 Jan 2026 02:35:17 EST https://www.sciencedaily.com/releases/2026/01/260120015650.htm https://www.sciencedaily.com/releases/2026/01/260116035313.htm Bamboo shoots may be far more than a crunchy side dish. A comprehensive review found they can help control blood sugar, support heart and gut health, and reduce inflammation and oxidative stress. Laboratory and human studies also suggest bamboo may promote beneficial gut bacteria and reduce toxic compounds in cooked foods. However, bamboo must be pre-boiled to avoid natural toxins.

Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells. That leak may weaken muscles directly or activate processes that slowly break them down, offering a long-sought explanation for statin-related aches.

The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results.

Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal. People who ate two vitamin C–packed kiwifruit daily showed thicker, healthier skin. The findings suggest glowing skin really does start from within.

Kids on plant-based diets often had better heart health markers, including lower “bad” cholesterol, and consumed more fiber and vitamins. But the study also flagged common nutrient gaps—especially vitamin B12 and calcium—without supplementation. Experts say plant-based eating is achievable for kids, but only with careful planning. Sun, 21 Dec 2025 00:26:48 EST https://www.sciencedaily.com/releases/2025/12/251219093319.htm https://www.sciencedaily.com/releases/2025/12/251209043050.htm New research is challenging one of medicine’s oldest assumptions: that cancer must be attacked to be cured. By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor aggressiveness, cancer biomarkers, immune checkpoints, and stem-cell–related markers—all without side effects. Their approach focuses on “healing” tumors by eliminating harmful cell-free chromatin particles released from dying cancer cells, which normally inflame and worsen the disease. The findings hint at a future where inexpensive nutraceuticals could transform cancer therapy.

Cooking doesn’t improve absorption, but adding oil-based dressings—or even more advanced nanoemulsion sauces—does. These combinations dramatically increase access to kale’s carotenoids. The research could inspire new, healthier dressings designed to supercharge everyday vegetables.

The findings point not to the oil itself but to the fat-derived molecules it produces inside the body, called oxylipins, which can trigger inflammation, alter liver function, and influence genes tied to metabolism. Sun, 30 Nov 2025 10:46:22 EST https://www.sciencedaily.com/releases/2025/11/251129044503.htm https://www.sciencedaily.com/releases/2025/11/251118220052.htm Scientists have developed a new molecule that breaks down beta-amyloid plaques by binding to excess copper in the brain. The treatment restored memory and reduced inflammation in rats, while also proving non-toxic and able to cross the blood–brain barrier. Because it’s far simpler and potentially cheaper than existing drugs, researchers are now pursuing partnerships to begin human trials.
