Vitamin D protection from the effects of COVID-19

Vitamin D protection from the effects of COVID-19

Posted On: 07/05/2020

A very recent study of 10,933 people from 25 trials conducted in 15 countries has shown how important Vitamin D is in protecting us from Acute Respiratory Infections (ARI), such as those resulting from seasonal flu and coronavirus infections.

Vitamin D supplementation is recommended for people who have low levels of the vitamin, such as those being denied sunshine by remaining indoors. For more information see the plain English summary and scientific paper here:

Vitamin D supplementation to prevent acute respiratory infections: individual participant data meta-analysis

Key results

"Overall, vitamin D supplements reduced the risk of having at least one ARI from 42% to 39%. We also showed that vitamin D had greater protective effects when it was given daily or weekly to people with the lowest vitamin D levels: the risk of having at least one ARI was reduced from 60% to 32% in these individuals. Vitamin D was not effective in protecting against ARIs when it was given in large, widely spaced doses. Taking vitamin D supplements was found to be safe."
