The role of vitamin D

1. Improve fatigue

Vitamin D is good for promoting the functioning of the body's immune system. When our immune system is low, we may have general fatigue and the whole person is tired. At this time, we need to supplement vitamin D. Lack of vitamin D, we may have seasonal fatigue, especially in winter. Vitamin D supplementation is very important to improve body fatigue and improve body immunity.

2, promote bone growth

Vitamin D is an essential nutrient for human bone growth. Vitamin D can promote bone growth by increasing the absorption of calcium and phosphorus in the small intestine, thus promoting bone calcification. According to research, children, pregnant women and the elderly, a daily supplement of 300-400 national units of vitamin D is beneficial to promote the absorption of calcium in the body. Therefore, if we find that the calcium in the body is not fully absorbed, the calcium content is too low, you can supplement calcium on the basis of appropriate vitamin D.

3, regulating calcium and phosphorus metabolism

The main function of vitamin D is to regulate calcium and phosphorus metabolism, to promote intestinal calcium and phosphorus and bone calcification, and to maintain blood calcium and phosphorus balance. Active vitamin D acts on the nucleus of small intestinal mucosal cells, thus promoting the biosynthesis of troponin. Calcium transporter protein binds to calcium to form a soluble complex, promoting calcium absorption. Vitamin D promotes the absorption of phosphorus, which may be indirectly absorbed through calcium. Therefore, vitamin D can maintain the balance of calcium and phosphorus in the body to a certain extent, which is more conducive to promoting the calcification of bone tissue.
