What is vitamin D3?
Everyone is no stranger to vitamin D. It is a fat-soluble vitamin and is considered to be a hormone precursor that acts on calcium and phosphorus metabolism. It is closely related to sunlight, so it is also called “sunshine vitamin.”
So what about vitamin D3? Vitamin D3, also known as cholecalciferol, is a form of vitamin D that has been shown to be a truly active form of vitamin D in the body. There are currently at least 10 known vitamin Ds, but the most important ones are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).
Where does vitamin D3 come from?
Here we mainly talk about vitamin D3. It is mainly synthesized by the body itself. The skin of the human body contains a kind of cholesterol, which turns into vitamin D3 after being exposed to sunlight. Therefore, if the child can fully receive direct sunlight for 4 to 6 hours, the self-synthesized vitamin D3 will basically meet the needs.
but! Under the influence of air pollution and weather changes in various places, the time for people to receive sunshine in all countries is decreasing. In addition, many countries have clearly defined the time limit for receiving sunshine. Therefore, vitamin D deficiency is widespread throughout the world. . In addition, it is also necessary to consider problems such as an increase in skin cancer due to ultraviolet radiation.
What’s the use of vitamin D3?
Vitamin D3 has the following physiological functions:
- Improve the body’s absorption of calcium and phosphorus, so that the levels of plasma calcium and plasma phosphorus reach saturation.
- Promotes growth and bone calcification and promotes healthy teeth;
- Increases the absorption of phosphorus through the intestinal wall and increases the reabsorption of phosphorus through the renal tubules;
- Maintain normal levels of citrate in the blood;
- Prevent amino acid loss through the kidneys.
Do you think that vitamin D3 is nothing more than this?
International intensive research on vitamin D shows that vitamin D is no longer considered a nutritional necessity for the prevention of childhood rickets. The significance of vitamin D for health is more widely recognized and confirmed in numerous clinical trials, including:
- Reduce the incidence of common cancers such as breast cancer, lung cancer, colon cancer, etc.;
- Prevention and treatment of autoimmune diseases, hypertension and infectious diseases;
- Vitamin D regulates the development and function of the placenta, suggesting that maintaining a good vitamin D level in pregnant women can prevent pregnancy complications such as abortion, pre-eclampsia, and preterm birth;
- Getting enough vitamin D in the uterus and infants can reduce the incidence of type 1 diabetes, asthma and schizophrenia.
All in all, the treatment and prevention of vitamin D deficiency is very important for the overall health development of all people, especially for women and children!
