“Clinicians determine a person's vitamin D status by measuring 25-hydroxyvitamin D3, or 25(OH)D3 — the inactive circulating form of vitamin D. However, a new technique, high-throughput liquid chromatography-tandem mass spectrometry (LC-MS/MS), allows researchers to quantify additional vitamin D metabolites.”

“Vitamin D was classified as sufficient above 50 nmol/L, insufficient above 30 through 50, and deficient at 30 or below. Each group was compared with adults who had neither abdominal obesity nor low vitamin D, accounting for demographic, health, and lifestyle differences.”

“The assessments indicated that approximately 90 percent of the patients had low vitamin D levels, even when the data were adjusted for age and severity of illness. The patients with low vitamin D levels spent an average of six days longer on mechanical ventilation compared to patients with higher levels.”

“Evidence now suggests vitamin D also influences body composition and muscle strength. A recent study in mice showed that high vitamin D intake increased muscle strength and mass without altering body weight.”

“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.”

“How do I decide how much vitamin D to supplement with? Can you get too much vitamin D? Is there a difference in vitamin D made from the sun versus a supplement? What form of vitamin D is more bioavailable and absorbed better?”

“Observational data demonstrate that people who take vitamin D regularly are 34 percent less likely to develop COVID-19. Findings from a recent study show that high-dose vitamin D booster therapy reduces the risk of death among COVID-19 patients.”

“Vitamin D did not make the full four-hour response larger, which argues against a broad increase in post-exercise muscle protein synthesis. Instead, it may have changed early protein handling, giving muscle tissue a stronger early supply of essential amino acids needed for new muscle-protein production.”

“Findings in a recent report indicate that vitamin D may reduce the number of cancer deaths, saving thousands of dollars. The authors of the study drew on data regarding age- and sex-specific cancer deaths in the German Center for Cancer Registry.”

“Vitamin D is a fat-soluble vitamin that plays key roles in several physiological processes, including immune function. Robust evidence demonstrates links between poor vitamin D status and severe outcomes following infection with SARS-CoV-2, the virus that causes COVID-19.”
