Since the beginning of the health crisis, several reviews of the scientific literature seem to confirm the interest in vitamin D supplementation, identified since 2017 by the World Health Organization as an effective means of preventing respiratory tract infections. One such study summarizes: “Adequate vitamin D supplementation should be implemented in populations where vitamin D deficiency is widespread. There is nothing to lose from this implementation and potentially a lot to gain ”.
England, Norway …
At this stage, the WHO does not (yet?) Recommend such integration to prevent Covid-19. But some countries are taking the lead. Thus, in England, the government officially asked its public health agencies to produce recommendations for its use in the context of the pandemic. It is preparing, according to the Daily Telegraph, to provide free doses of vitamin D to 2 million elderly and vulnerable people, since December and for a period of 4 months.
In Norway, it is the traditional cod liver oil, very rich in vitamin D, that is of interest to researchers. Oslo University Hospital last week appealed to 70,000 volunteers for the large study, which will end in April 2021. “Half of the 70,000 participants will be taking cod liver oil every day, while the other half will receive a placebo. Participants will not be informed which group they belong to ”, specifies the hospital, which wants to measure the possible benefits of cod liver oil on Covid-19, but also on flu and colds.
And in France?
A trial is underway at Angers University Hospital. The CoVit-Trial project, coordinated by this CHU and which includes patients from 8 other hospitals, aims to “evaluate the effectiveness of administering a high dose of vitamin D compared to a standard dose in elderly patients with Covid-19”. clinical trial will end in early 2021 and its conclusions are eagerly awaited “given the high level of evidence this study could provide. No data are available from an interventional study in the elderly.
In early October, in a study published in Nutrients, the CHU’s geriatrics team concluded that regular vitamin D supplementation in elderly, frail and hospitalized patients with Covid-19 was associated with a less severe form and with better survival rate. This work involved 77 patients.
Good to know: According to the public version of the Vidal Medical Dictionary, “an overdose of vitamin D causes nausea, headache, muscle and bone pain, heart rhythm disturbances and calcium deposits in the kidneys, blood vessels, heart and lungs. severe, life-threatening kidney problems. ”These side effects appear as soon as the daily intake exceeds 50,000 IU, equivalent to 1.25 mg per day.
