2. vitamin D3 and its functions

A good vitamin D3 supply is essential for humans. Vitamin D3 is the only vitamin that can be produced by the body in certain amounts. It is produced in the skin cells under the influence of solar radiation.

Functions of vitamin D3:

• Control of blood sugar
• Maintenance of a healthy immune system
• Regulation of calcium metabolism
• Growth of hematopoietic cells
• Promotion of bone growth
• Formation of proteins
• Bone mineralization

3. what is the daily requirement of vitamin D3?

The German Society for Nutrition recommends a daily amount of vitamin D3 of 4000 IU for an adult person. However, it should always be noted that height, gender and body weight play a major role in this. The age is especially important, because in children and infants the daily content is significantly lower. In pregnant and breastfeeding women, the daily amount of vitamin D3 increases significantly again.

4. vitamin D3 in the form of dietary supplements

Vitamin D3 is offered in the form of capsules and tablets. Both forms are easy to use and enter the circulation quickly. However, vitamin D3 tablets are sold in pharmacies, which in many cases contain artificial additives or are manufactured abroad. Vitamin D3 capsules often contain only the active ingredient in a vegetable cellulose shell and can therefore be produced without fillers. In general, it should always be ensured that the product has been produced in Germany to guarantee a consistently high preparation quality.

5. conclusion: which foods are rich in vitamin D3?

There are many foods which contain vitamin D3. Especially products of animal origin are rich in vitamin D3. These include fish, for example. An adult should consume about 4000 IU of vitamin D3 a day. The human body can produce vitamin D3 itself with the help of the skin. Supplementation of vitamin D3 in the form of dietary supplements can be very helpful.
