What does Vitamin D3 do?
Vitamin D3 (cholecalciferol) is synthesized in the skin through UVB radiation. It regulates calcium and phosphate metabolism and is therefore crucial for strong bones and muscle function. Furthermore, it plays an important role in immune defense and is associated with a reduced risk of infections and fatigue.
Studies show that supplementation is particularly beneficial during winter months or with low sun exposure. The liquid form in MCT oil (from coconut) ensures optimal absorption of the fat-soluble substance.
