“This supports arguments for designing clinical trials that can test whether or not vitamin D may be a viable intervention to lower the risk of the disease, especially in persons of color.” “These new results tell us that having vitamin D levels above those normally considered sufficient is associated with decreased risk of testing positive for COVID-19, at least in Black individuals,” said David Meltzer, MD, PhD, Chief of Hospital Medicine at UChicago Medicine and lead author of the study. A separate study recently found that more than 80% of patients diagnosed with COVID-19 were vitamin D deficient. In the current study, those results were further supported, finding that individuals with a vitamin D deficiency had a 7.2% chance of testing positive for the virus. This research is an expansion of an earlier study showing that a vitamin D deficiency (less than 20 ng/ml) may raise the risk of testing positive for COVID-19.
The research team is now recruiting participants for two separate clinical trials testing the efficacy of vitamin D supplements for preventing COVID-19. The study looked at data from more than 3,000 patients at UChicago Medicine who had had their vitamin D levels tested within 14 days before a COVID-19 test. Statistically significant associations of vitamin D levels with COVID-19 risk were not found in white people. While levels of 30 ng/ml or more are usually considered sufficient, the authors found that Black individuals who had levels of 30 to 40 ng/ml had a 2.64 times higher risk of testing positive for COVID-19 than people with levels of 40 ng/ml or greater. The study, published in JAMA Open Network on March 19, retrospectively examined the relationship between vitamin D levels and likelihood of testing positive for COVID-19.

Note that the longevity effects appeared limited to vitamin D3, though, the type derived from plants and animals-not vitamin D2, the type derived from yeast and mushrooms.
Benefits of vitamin d video skin#
(The lamps emit mostly UVA, which increases melanoma skin cancer risk while producing less vitamin D.) I also don’t recommend tanning beds because they can be both ineffective and dangerous. Mushrooms, interestingly, also make vitamin D when exposed to sunlight radiation, but most mushrooms found in the produce section of our local markets don’t have any vitamin D because they’re grown in the dark. If you don’t get adequate sun exposure, I recommend 2,000 IU vitamin D supplements daily, ideally with the largest meal of the day. It’s also been shown to improve pain from menstrual periods and help prevent respiratory infections.
Is it necessary to take vitamin D supplements? Vitamin D, which is made mostly by animals, including ourselves, when we’re exposed to sunlight, may help us enjoy a longer life based on randomized, controlled studies.
