Vitamin D or calciferol

(1)

Vitamins are essential to proper body function. They are involved at low concentrations in many vital processes.

Vitamin D is part of the lipid-soluble vitamins, meaning that it is absorbed together with fats. It is one of the few vitamins that the body can produce.

Where to find vitamin D?

90% of vitamin D is produced by our body through exposure of the skin to the sun. Our diet provides the rest (oily fish, liver, egg yolk, oysters).

Vitamin D and sports

Vitamin D is essential to athletes as it promotes the intestinal absorption of calcium and phosphorus, thus enhancing bone mineralization. It thereby promotes bone development in children and helps prevent osteoporosis. Vitamin D also plays an important part in the fight against infections.

Vitamin D needs

The needs in adults are 5mg / day.

Vitamin D deficiency is common in the general population. It results in weak bones due to demineralization. Supplementation can be recommended in autumn and winter, whereas vitamin D overdoses are exceptional.
