“However, people with higher baseline vitamin D levels also benefited, although the effect was more modest (10 per cent risk reduction). Overall, the reduction in risk of acute respiratory infection induced by vitamin D was on a par with the protective effect of injectable 'flu vaccine against 'flu-like illnesses.”

“Conversely, people whose magnesium levels are sufficiently high require less vitamin D supplementation to achieve healthy levels. The recommended dietary allowance for magnesium for adults between the ages of 31 and 50 years is 420 milligrams for men and 320 milligrams for women per day.”

“Supplemental vitamin D intake, body mass index, and race/ethnicity had the greatest influence on vitamin D concentrations, and genetic variants had only a minor influence. Black women had the lowest vitamin D concentrations among the cohort, possibly contributing to their poorer outcomes following breast cancer diagnosis.”

“Young children who received supplemental vitamin D were less likely to have neurobehavioral problems later in childhood than those who didn't. Researchers gave 346 infants either low-dose (400 IU) or high-dose (1,200 IU) vitamin D daily from two weeks to two years of age.”

“Researchers measured concentrations of vitamin D in four regions of the participants' brains and reviewed the participants' cognitive assessments. They found that higher brain concentrations of vitamin D were associated with 25 to 33 percent lower odds of having dementia or mild cognitive impairment at the last assessment before death.”

“Vitamin D regulates over 900 genes in the body that affect the immune, musculoskeletal, and endocrine systems, among others. Previous research has shown that vitamin D deficiency may decrease athletic performance.”

“The study involved more than 12,000 adults who were dementia-free at the time of enrollment. Participants provided information about their vitamin D intake and underwent regular cognitive evaluations over a period of 10 years.”

“Interestingly, the association between low vitamin D concentrations and older brain age was only statistically significant for male participants. Vitamin D is a fat-soluble vitamin that is stored in the liver and fatty tissues of the body.”

“Vitamin D, a fat-soluble nutrient, is sequestered in adipose tissue, limiting its circulation—an effect amplified in obesity. Obese adults, for example, exhibit a 57 % smaller rise in circulating vitamin D3 after whole-body ultraviolet exposure and are more than half as likely to reach sufficient vitamin D levels than normal-weight adults.”

“The Endocrine Society defines optimal blood levels of vitamin D as 40 to 60 nanograms per milliliter (ng/mL). Unfortunately, approximately 40 percent of people living in the United States are vitamin D deficient, based on Endocrine Society standards.”
