Vitamin D3

Vitamin D3, also known as cholecalciferol, is one of the most important nutrients for human health. This vitamin is fat soluble and can be obtained from both food and sunlight.

Cholecalciferol is the active form of vitamin D3, which plays a key role in regulating calcium and phosphorus levels in the blood. It helps improve calcium absorption from the intestines and reduces calcium excretion through the kidneys. Vitamin D3 also helps maintain healthy bones and teeth, strengthens the body's immune system, and reduces the risk of developing certain diseases.

A lack of vitamin D3 can lead to a number of diseases such as osteoporosis, cancer, diabetes and cardiovascular disease. However, too much vitamin D3 can also be harmful to health.

The human body can synthesize vitamin D3 when the skin is exposed to ultraviolet rays from the sun. However, in some cases, such as in winter or when there is insufficient sunlight, it is necessary to obtain vitamin D3 from food or supplemental sources.

Good sources of vitamin D3 include fatty fish such as salmon, sardines and tuna, as well as egg yolks and dairy products. There are also special vitamin D3 preparations in the form of capsules, tablets and liquids that can be used to supplement the vitamin.

Overall, vitamin D3 plays an important role in maintaining the health of the body, especially the bones and immune system. It is necessary to monitor the level of vitamin D3 in the body and, if necessary, increase its intake through food or additional sources.
