Doctor's answer (1)
Dr. Yang Ziqi
Vitamin D is a fat-soluble vitamin whose main functions and effects include:
1. Promoting calcium and phosphorus absorption: Vitamin D promotes the absorption of calcium and phosphorus in the small intestine, playing an important role in the formation and maintenance of bones and teeth. A deficiency in vitamin D leads to reduced absorption of calcium and phosphorus, affecting bone health. In children, it may cause rickets, while in adults, it may lead to osteomalacia or osteoporosis.
2. Bone health: Vitamin D regulates calcium and phosphorus metabolism, maintaining blood calcium and phosphorus levels within the normal range, thus directly influencing bone health. Adequate vitamin D helps prevent osteoporosis and fractures.
3. Immune system: Vitamin D also participates in immune regulation, helping to enhance the activity of immune cells and improve the body's resistance to infections.
4. Mental health: A deficiency in vitamin D may be associated with depressive symptoms, and supplementing with vitamin D may help improve mood.
