|Calcitriol 0.25 mcg
Calcitriol is a form of vitamin D that helps in the absorption of calcium in the blood. Vitamin D3 helps process essential minerals in the body, like calcium and phosphorus. When the skin is exposed to sunlight, vitamin D is made by the body. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D from the sun, thus leading to vitamin D3 deficiency. Thus, supplementing is necessary to maintain optimum bone health.
