Laboratoires S.M.B.’s Vitamin D3
The adjuvant of choice against COVID-19
What is Cholecalciferol ?
Cholecalciferol, also known as Vitamin D3 is a precursor of the active vitamin D, which is involved in various metabolic processes. It is a secosteroid that is produced by exposure to sunlight or obtained through food. Nevertheless, these physiological intakes are not sufficient to ensure adequate levels of vitamin D in the body and supplementation is mandatory.
What role does Cholecalciferol play in COVID 19 infection ?
Vitamin D3 deficiency is widespread throughout the population and among its symptoms, there is an increased susceptibility to infection, possibly to COVID 19.
It has been shown that the infection level within the population and the mortality rate were strongly associated to the level of vitamin D3
In parallel, Vitamin D has an established effect on the immune system and it has been shown that vitamin D3 supplementation reduces the susceptibility to respiratory tract infections
As a consequence, our Vitamin D3 product is an excellent adjuvant to treatment. It is capable of preventing white blood cells from releasing too many inflammatory cytokines (« Cytokine Storm »)which are responsible for the most severe and lethal cases of COVID 19.
