Introduction
Under normal circumstances, the reference range for 25-hydroxyvitamin D is generally greater than 50 nmol/L. 25-hydroxyvitamin D is an active metabolite of vitamin D2, primarily derived from ergosterol in plants. It helps promote better absorption of trace elements such as calcium and phosphorus in the human body and is used to prevent conditions such as chronic hypocalcemia, hypophosphatemia, and rickets.
Under normal circumstances, the reference range for 25-hydroxyvitamin D is generally considered to be greater than 50 nmol/L. Specific details are as follows:
25-hydroxyvitamin D is an active metabolite of vitamin D2, primarily derived from ergosterol in plants. It helps promote better absorption of trace elements such as calcium and phosphorus in the human body, and is used to prevent chronic hypocalcemia, hypophosphatemia, rickets, as well as conditions like regional enteritis and chronic diarrhea. When the level of 25-hydroxyvitamin D is greater than 50 nmol/L, it is generally considered sufficient. If the level falls between 30 and 50 nmol/L, it indicates a deficiency in 25-hydroxyvitamin D.
It should be noted that insufficient levels of 25-hydroxyvitamin D in the body may lead to systemic calcium deficiency, resulting in loose teeth, deteriorated bone health, and may also cause disturbances in phosphorus metabolism. It is recommended to get regular sun exposure and consume more eggs, dairy products, fish, animal liver, lean meat, and other foods to help supplement 25-hydroxyvitamin D.
