Vitamin D is a fat-soluble vitamin which means it is dissolved in fats. It usually exists in two forms: vitamin D2 and vitamin D3 (or cholecalciferol which is the most absorbent form). In the body, vitamin D3 has two origins: it is naturally synthetized by the skin exposed to sun’s ultraviolet actions and it is supplemented through the diet in a smaller quantity. Mainly stored in blood, muscles, adipose tissues, liver and kidneys, it has four predominant physiological functions:
• It maintains the phosphocalcic balance.
• It maintains muscle functions.
• It optimizes a proper functioning of the immune system.
• It is useful for keeping bones and teeth healthy.
Starting in autumn, when there is less sunshine, the synthesis of vitamin D progressively shrinks over the days to reach low rates in mid-winter.
Who needs vitamin D ? Women who are pregnant or breastfeeding, children, seniors, individuals with high skin pigmentation, individuals who are not exposed to the sun or those whose clothing cover the majority of the skin the whole year, need to take vitamin D supplements, at least from November to March-April.
