Vitamin D is often known as the “sunshine vitamin” because it is synthesized in response to exposure to sunlight. There are two major natural sources of vitamin D, cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2). Vitamin D3 is synthesized in the skin of many herbivores and omnivores upon exposure to UV light from sunlight.
