Vitamin D3 5000 IE

Vitamin D is a fat-soluble vitamin and can be ingested via food or synthesized endogenously in the body. Therefore, the absorption can be achievied via two different ways.

When ingested via food, vitamin D, due to its fat solubility, is absorbed together with the lipid metabolism in the intestine. During the endogen synthesis, the vitamin is produced via several metabolic pathways from cholesterol. The UVB rays of the sun convert the cholesterol derivate 7-dehydrocholesterol into pre-vitamin D3 and then into the active vitamin D3. After entering the blood circulation from the skin, vitamin D3 (cholecalciferol) is adsorbed to the vitamin D binding protein (DBP) and transported to liver and kidney. There it is transformed into the active vitamin D hormone. This hormone is again bound onto the DPB and transported to several tissues and organs. There it can unfold its health-related effects together with the vitamin absorbed from food.

To verify its health effects, Vitamin D3 5000 IU is derived from wool fat. The vitamin is contracted in form of oil, so that the stability and optimal freshness can be kept. Together with olive oil, the liquid oil is filled into a capsule, so that the vitamin is still optimal bioavailable.

According to the European Food Safety Authority (EFSA) has vitamin D several positive effects on the health, like:

• the contribution to the normal function of the immune system and healthy inflammatory response,
• the contribution to the maintenance of normal muscle function,
• the contribution to the maintenance of normale bones and teeth.
