What a high Vitamin D Total-25 Hydroxy means, and common causes

A level above 100 ng/mL is higher than needed and almost always comes from taking too much supplement. Very high levels can raise blood calcium.

Common causes: Excessive vitamin D supplements or injections, usually self-prescribed or repeated without retesting. Sunlight alone does not cause toxicity.

What a low Vitamin D Total-25 Hydroxy means, and common causes

Below 20 ng/mL is deficient and 20 to 29 is insufficient. Deficiency is extremely common in Indian cities even in sunny months.

Common causes: Limited sun exposure, indoor work, air pollution, sunscreen, darker skin, covering clothing, obesity, malabsorption, and chronic kidney or liver disease.

Frequently asked questions

30 to 100 ng/mL is considered sufficient. Below 20 is deficient and 20 to 29 is insufficient.
