Researchers Discover a Hidden Vitamin D Problem That Persists Year-Round

A new study suggests that some groups may not experience the expected seasonal boost in vitamin D levels, even during the sunniest months of the year. Many people assume that spending more time outdoors during summer naturally restores vitamin D levels after the darker winter months. But new research suggests that for some groups, that [...]

Constantly Tired? Scientists Say These Vitamin Deficiencies May Be Why

Scientists have uncovered a potential nutritional link to chronic fatigue. Healthy adults with signs of vitamin B12 and folate deficiencies were more likely to experience fatigue or lower motivation. Chronic fatigue has become a common part of modern life. Many people struggle with long work hours, packed schedules, and persistent exhaustion that never seems to [...]

Doctors May Need To Rethink Calcium and Vitamin D Recommendations After Major Review

New evidence suggests calcium and vitamin D supplements may do far less to prevent fractures and falls than widely believed. Calcium and vitamin D supplements, whether taken separately or together, provide little to no meaningful benefit in preventing fractures or falls in most older adults, according to a major review published in The BMJ. Nearly [...]

Could Low Vitamin D Be Making Your Pain Worse?

Low levels of vitamin D may make recovery from breast cancer surgery more painful and increase the need for opioid medications, according to research published online in the journal Regional Anesthesia & Pain Medicine. Researchers say patients with vitamin D deficiency (below 30 nmol/L) could potentially benefit from taking supplements before undergoing a radical mastectomy. [...]

New Vitamin B12-Based Therapy Could Change How Brain Cancer Is Treated

Researchers have identified a vitamin B12–based compound that appears capable of crossing the blood–brain barrier and selectively accumulating in glioblastoma tissue. For decades, one of the biggest problems in brain cancer treatment has had little to do with killing cancer cells and everything to do with reaching them. The brain’s protective blood-brain barrier (BBB) blocks [...]

This Common Vitamin May Help Stop Prediabetes From Turning Into Diabetes

Vitamin D may help prevent type 2 diabetes in people with specific genetic variations, offering a possible path toward personalized diabetes prevention. More than 40% of U.S. adults have prediabetes, a condition in which blood sugar levels are elevated but not yet high enough for a type 2 diabetes diagnosis. New research suggests vitamin D [...]

Vitamin C May Fight Cancer in a Surprising Way

Intravenous vitamin C may help fight cancer and reduce treatment side effects, though it remains experimental. Linus Pauling’s theory was flawed but partly correct. Few scientists shaped modern chemistry as profoundly as Linus Pauling. The American researcher won two Nobel Prizes and helped uncover the nature of chemical bonds and the structure of proteins, achievements [...]

New Study Reveals How Vitamin D Could Calm Gut Inflammation

Vitamin D supplementation may help rebalance immune responses to gut bacteria in people with IBD, though larger controlled studies are needed. Vitamin D supplements may influence how the immune system reacts to gut bacteria in people with inflammatory bowel disease (IBD), according to a study led by Mayo Clinic and published in Cell Reports Medicine.

Experts Reveal the Surprising Cancer Link Behind a Common Vitamin

Vitamin B12 is essential, but more is not always better. Researchers say extremely high levels may signal underlying illness, while balanced intake is key for long-term health. We’ve all heard the advice: eat plenty of fruits and vegetables, get enough vitamins, and stay healthy. In general, that guidance is sound. But some nutrients are more [...]

A Simple Vitamin May Hold the Key to Treating Rare Genetic Diseases

A new study suggests that certain genetic diseases may be treatable with carefully matched vitamins, including a deadly childhood disorder that responded strikingly to vitamin B3. Scientists at Gladstone Institutes have taken an unusual route in the search for treatments for deadly genetic diseases. Rather than choosing a disease first and then looking for a [...]

A Common Vitamin Could Hold the Key to Treating Fatty Liver Disease

A hidden molecular switch linked to liver disease may be reversible, using an unexpected, familiar compound. About 30% of people worldwide are affected by metabolic-associated fatty liver disease (MASLD), a condition closely tied to obesity and type 2 diabetes that can quietly progress to liver damage. Despite its growing impact, treatment options remain limited. New [...]

New Research Shows Vitamin B12 May Hold the Key to Healthy Aging

Vitamin B12 may shape metabolism and aging more than previously understood. Vitamin B12 is typically associated with red blood cells and nerve health, but new research from Cornell University suggests its influence reaches much deeper into how the body produces energy and maintains muscle. The study, published in the Journal of Nutrition, reveals previously unrecognized [...]

Researchers Unveil Groundbreaking Sustainable Solution to Vitamin B12 Deficiency

A modified form of Spirulina may offer a more sustainable source of vitamin B12. A new study suggests that Spirulina, long promoted as a nutrient-rich food, may finally overcome one of its biggest nutritional weaknesses. Researchers report that a specially grown form of the blue-green algae can produce biologically active vitamin B12 at levels comparable [...]

Popular Vitamin D Supplement Has “Previously Unknown” Negative Effect, Study Finds

A new meta-analysis is challenging long-standing assumptions about vitamin D supplements. New research from researchers at the University of Surrey, the John Innes Centre, and Quadram Institute Bioscience is raising questions about a common choice in supplements: vitamin D2 versus vitamin D3. Their findings suggest the two forms may not be interchangeable and, in some [...]
