“Most studies seem to show a reduction in all-cause mortality (or improvements of various outcomes) when blood status is above 40ng/ml but not in excess of 60ng/ml. I've referred to this as the Vitamin D sweet spot before and I think it makes a good argument for blood testing occasionally.”

“Findings from a recent study suggest that supplementation with calcifediol, an intermediate molecule in the production of the active form of vitamin D, reduces the risk of death due to COVID-19. Unlike other vitamins – trace nutrients that must be consumed in the diet – vitamin D is a steroid hormone that is produced in the body.”

“> "For the babies who had very low vitamin D, their risk was about twice as high as those babies who had optimal vitamin D," says McGrath. > "But the amazing thing was that the study that was based in Denmark, where low vitamin D is quite common, we found that if vitamin D is linked to schizophrenia our statistics suggest that it could explain about 40% of all schizophrenias.”

“A key limitation is that this was a later analysis of a trial originally designed for asthma, not cognition, so the memory findings should be treated as suggestive. Still, the results raise the possibility that prenatal vitamin D could influence specific aspects of later cognitive performance.”

“From the article: > It's commonly believed that sun exposure is key to maintaining normal levels of vitamin D and therefore assumed that Mediterranean women are at lower risk of hypovitaminosis than those from Northern Europe. However in countries such as Spain, Italy, Greece and Turkey, Vitamin D deficiency occurs in up to 90 % of pregnant populations.”

“Severity: “Based on CDC criteria, among our study patients, 74% of those had severe COVID-19 infection. The data analyses revealed that the severe disease infection was less prevalent in patients with vitamin D sufficiency (63·6% vs. 77·2% p=0·02).” Mortality: No one under the age of 40 died. In those over 40, 20% were vitamin D insufficient but they comprised of 90.3% of the deaths.”

“A new study shows that lifestyle modifications, including exercise, vitamin D intake, and cognitive training, improve functional brain connectivity in older adults with mild cognitive impairment. The study involved 120 older adults (ages 60 to 80 years) with mild cognitive impairment.”

“While this data is very interesting and in line with many other associative studies... to definitively prove that the link that vitamin D and breast cancer survival is causal, randomized clinical trials vitamin D supplementation vs placebo would be necessary.”

“The average vitamin D level among women whose children developed ADHD was 29 nmol/L. There are biologically plausible explanations for the association between developmental vitamin D deficiency and an increased risk of offspring ADHD.”

“Each 10nmol/L increase in vitamin D in the blood was associated with a 0.78 mL/kg/min increase in VO2 max. This was an observational study so it is impossible to say whether vitamin D improves exercise capacity but the association was strong and increased in a dose-dependent manner.”
