Vitamin D supplements do not protect against COVID-19

No, the pill sun is not a real shield from Covid. However, hope for easy and inexpensive COVID-19 vitamin D prophylaxis seemed plausible. Several studies have shown that people who develop severe COVID often lack this protein, which is known to play innate immunity to respiratory viruses. Even better, vitamin D has been shown to stimulate the expression of peptides that bind to the coronavirus Spike protein and prevent it from binding to our cells ’ACE-2 receptors. British researchers developed a Phase 3 clinical trial to test this hypothesis (called CORONAVIT), the findings of which were published online in 2022. March 23 pre – printing (not yet reviewed). Unfortunately, their results show that vitamin D supplements do not affect the chances of developing Covid.

Supplements increase the amount of vitamin D.

In this randomized study, the researchers wanted to determine whether correcting for vitamin D deficiency with dietary supplements could protect against Sars-CoV-2 coronavirus. A total of 6,200 participants aged 16 years and older (median age 60.2 years) were divided into three groups: a control group, a group treated with a low dose of vitamin D (800 IU daily), and one who had a higher dose of vitamin D. doses of this vitamin (3 200 IU per day; IU or IU in French as the ‘international unit’ used to measure the amount of pharmacological product). Participants received food supplements at home for six months – from 2020. December. until 2021 June
