Dietary vitamin D intake is only about ten percent. Sun rays and the skin are important in vitamin D production (endogenous synthesis). The body hardly produces vitamin D in winter, because it needs UVB to make provitamin D3. Then this is converted by the liver cells in the storage form calcifediol, which regulates the bone and calcium metabolism.

What is vitamin D good for? The main vitamin D function in the body is in the area of the bones. But the vitamin has many other tasks, so you should pay special attention to the vitamin D intake.
Healthy levels of vitamin D ensure that bone stem cells form, and vitamin D is important for the metabolism of the mineral phosphate, which is bound in the human body in bones and teeth.
In addition, vitamin D regulates the calcium balance. This mineral is instrumental in building and maintaining bones and teeth.
Other functions of vitamin D, however, which are not sufficiently scientifically proven:
- Support immune system
- Anti-carcinogenic effect (tumor preventive)
- Protection against Parkinson’s and dementia
- Reduce the risk of multiple sclerosis
- Protection against rickets
- Symptom relief in asthma
- Protection against depression
How much vitamin D do you need now? According to estimates of experts, the vitamin D requirement of an adult is 20 μg daily of vitamin D. Infants need half of them. Dietary intake is usually not enough to reach that level unless the body produces vitamin D, and the DGE recommends taking a supplement containing vitamin D.
Previously, children had to take cod liver oil that was rich of natural vitamin D, nowadays there are tasteless pills and tablets with vitamin D. Babies need the vitamin (and possibly even as a baby in the form of a substitution) to prevent rickets, the lack of mineralization of the bones.
Vegans should pay particular attention to their vitamin D value, or the appropriate nutritional choices and enough time in the sun. Vitamin D is only contained in a few vegan foods, for example in avocado or mushrooms.
