Vitamin D is often discussed in relation to muscle health, but whether it changes the muscle's response to exercise and protein intake has remained largely unclear. In a new study, researchers tested whether vitamin D supplementation could amplify that response in healthy adults. The final analysis of the trial included 17 recreationally active adults who took either 3,000 IU of vitamin D3 per day or a placebo for 12 weeks. Before and after the supplementation period, participants came to the lab after an overnight fast, completed single-leg resistance exercise, and drank about 22 grams of wh... exercise muscle protein vitamin d
Read moreVitamin C supports collagen production and stress defenses, yet few studies directly measure how diet influences vitamin C inside living skin. A new study tackled this gap by tracking how increasing vitamin C intake from whole foods changes vitamin C levels inside different layers of human skin. The researchers worked with two cohorts. In the first cohort, they measured vitamin C in the dermis (the deeper, collagen-rich skin layer) and epidermis (the outer, cell-rich skin layer) from 38 adults undergoing elective surgery and related these values to fasting blood levels of vitamin C. In the se... skin vitamin c

Findings from a recent study demonstrate that including mushrooms as part of a healthy dietary pattern provides many essential nutrients. Mushrooms are edible fungi, generally categorized as vegetables in the human diet. They are rich sources of many vitamins and minerals, including B vitamins, potassium, and selenium. When grown in the presence of ultraviolet light, mushrooms are good sources of vita... nutrition micronutrients
Read moreA growing body of evidence suggests that vitamin D plays a critical role in preventing and treating COVID-19. Observational data demonstrate that people who take vitamin D regularly are 34 percent less likely to develop COVID-19 (https://academic.oup.com/ajcn/advance-article/doi/10.1093/ajcn/nqaa381/6123965). Findings from a recent study show that high-dose vitamin D booster therapy reduces the risk of death among COVID-19 patients. The retrospective, cross-sectional observational study involved 986 COVID-19 patients admitted to two hospitals in the United Kingdom (Royal Preston Hospital and ... vitamin d covid-19

From the article: > "Even marginal vitamin C deficiency in the mother stunts the fetal hippocampus, the important memory centre, by 10-15 per cent, preventing the brain from optimal development," says Professor Jens Lykkesfeldt.

Vitamin D is a hormone that regulates nearly 5% of the human genome and activates anti-inflammatory genes. 32 studies from January 1966 to January 2013 with more than 500,000 participants found that vitamin D blood levels between 40-60 ng/ml were associated with the lowest all-cause mortality.
