Vitamin D3 (cholecalciferol) works in the body to help the absorption of calcium and phosphorus, all of which help to maintain healthy, strong bones, teeth and nails.
Vitamin D is made by the body when the skin is exposed to sunlight, but it can be hard to maintain high levels of this vitamin if you do not have much exposure to the sun, especially as it is also important to ensure you protect the skin against sun related conditions such as melanomas and sunburn. This is why health supplements that contain Vitamin D are part of many people’s defences against aging and poor health.
