A study of more than 5,500 people suggests that monitoring hormone levels and managing weight may help reduce the risk of premature death. For adults over 50, excess abdominal fat and low vitamin D levels may form a particularly dangerous combination. A study of more than 5,500 people found that participants with both conditions had [...]

Vitamin B12 is needed in only trace amounts, yet its absence can have far-reaching effects. Two micrograms is an almost unimaginably small amount. It weighs less than a tiny fragment of a grain of table salt. Yet adults need only around this amount of vitamin B12 each day, depending on the guideline used, to support [...]

Lower vitamin C levels were linked to reduced brain volume and weaker neural connectivity in older adults, suggesting a potential connection between nutrition and brain health. Could a common vitamin help preserve the brain as we age? A new study of more than 2,000 older adults in Japan found that people with lower levels of [...]

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 [...]

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 [...]

A vitamin D-based therapy may help remodel the protective barrier surrounding pancreatic tumors, offering a potential new treatment strategy. Pancreatic cancer is notoriously difficult to treat in part because tumors surround themselves with a dense, protective barrier that blocks drugs and suppresses immune activity. Now, a small clinical trial led by researchers at Dana-Farber Cancer [...]

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 [...]
