Vitamin D3

Vitamin D3, also known as cholecalciferol, is produced in the skin when it is exposed to sunlight, can be consumed in the diet, and is a hormone naturally produced in the body. Vitamin D3 is a fat-soluble vitamin that helps regulate calcium and phosphate levels in the body. It is important for bone and muscle strength and supports immune function.

You can buy Vitamin D3 prescribed by a medical practitioner, filled by an FDA-registered pharmacy.

How Does Vitamin D3 Work?

Keep Your Bones Strong

Vitamin D is available in foods, supplements, and sunlight. Once absorbed, vitamin D undergoes two hydroxylations, one in the liver and one in the kidney, to become active. Vitamin D is critical to maintaining bone density. When blood calcium levels fall, calcium will be pulled from the bone to compensate, decreasing bone density. Vitamin D binds to receptors on responsive genes and stimulates the production of proteins. The parathyroid hormone controls the production of active D3 (cholecalciferol).
