Does Vitamin D Protect Against Covid-19? In any case, this appears to be demonstrated by a recently published study in the UK. But if we are to make sure we are not deficient, vitamin D is not a preventative treatment and overdoses must be avoided.
Early studies showed it in the spring: being deficient in vitamin D makes you more vulnerable to the coronavirus. According to the results of a study of 216 patients and recently published in the Journal of Clinical Endocrinology & Metabolism, 82% of patients with Covid-19 who had to be hospitalized had a D deficiency. In the general population, only 40% people are lacking. As we know, vitamin D plays an important role in immunoregulation. According to numerous studies, it would also have a protective effect against viral and respiratory infections.
Free vitamin D for people at risk in the UK
This observation from the medical profession was heard by the British authorities: Secretary of State for Health and Social Protection Matt Hancock announced on November 7 that the elderly and vulnerable people would receive free vitamin D from December and for 4 months. . Several million people are affected, including those who are immunocompromised, suffering from severe respiratory ailments or suffering from cancer.
How to avoid vitamin D deficiency?
If reliable studies are still lacking to raise vitamin D to the rank of protective hormone against Covid-19, it remains that since the spring ANSES (National Agency for Food, Environmental and Occupational Safety) had encouraged the French to monitor their intake of vitamin D While it can be taken in the form of food supplements, it is even better assimilated when it comes from food. Foods rich in vitamin D are numerous: fatty fish (salmon, mackerel, sardines), organ meats (chicken or cod liver), egg yolk, butter or even cheese. It is also important to take advantage of the sun’s rays for about fifteen minutes every day, which, even hidden behind the clouds, allows our body to synthesize this vitamin D.
However, be careful not to exceed the maximum recommended dose, which is 4,000 IU of vitamin D per day. In rare cases, too high a dose can be harmful, including causing hypercalcemia affecting the kidneys.
