Vitamin D is a term that refers to a group of five fat-soluble vitamins that are classified as secosteroids, with research suggesting vitamin D3 (cholecalciferol) as being the most important form in humans. Since we produce much of our natural vitamin D transdermally (through the skin) via sunlight exposure, it is imperative that oral supplementation of vitamin D come in the form of D3. This is the most bioavailable form of vitamin D in a softgel, maximizing its absorption into the body.

Vitamin D3 is structurally similar to cholesterol, and is converted via the liver and kidneys to its active form calcitriol. Calcitriol goes on to perform a multitude of roles in the body, and is particularly crucial for proper absorption of the minerals calcium, iron, magnesium, phosphate and zinc. Calcitriol also regulates bone growth and regeneration, as well as immune, cardiac, and neuromuscular functions.
