Vitamin D and Immune Health

Low levels of vitamin D in the blood (25-hydroxyvitamin D) are associated with higher risks of acute upper and lower respiratory tract infections such as flu, according to a systematic review based on 39 human epidemiological studies. (1)

During late winter and early spring, solar radiation is weak and the vitamin D synthesis via our skin is at its lowest. As a result, our serum vitamin D levels are much lower compared to during summer. (2) It is especially important to supplement vitamin D via diet and supplement during this time.

Vitamin D is a very important nutrient for our immune system. (3) For example, vitamin D stimulates the expression of anti-microbial peptides in immune cells and in epithelial cells lining the respiratory tract. These peptides help protect the lung from infection. (4)

Pooled data from 25 randomized controlled trials involving nearly 11,000 subjects found vitamin D supplementation reduced the risk of acute respiratory tract infection. The protective effects were more evident in those who received vitamin D regularly and those who had low serum vitamin D at baseline. (5)

Maintaining healthy vitamin D levels helps support immune function in the long term.

However, please note there are no studies investigating the effect of vitamin D on the immune response to the novel coronavirus. There is no clinical evidence showing vitamin D helps prevent, reduce, or treat COVID-19 infection.
