Dr. Wang Lei
Vitamin D promotes the body's absorption of calcium. Without sufficient vitamin D, even a high dietary intake of calcium may impair calcium absorption, leading to decreased blood calcium levels and disrupting the body's calcium balance. Low phosphorus levels can also cause certain damage to the kidneys. In such cases, consuming more vitamin D can help the body absorb phosphorus and maintain phosphorus balance.
