Vitamin D3 (cholecalciferol) is a fat-soluble vitamin and pro-hormone synthesized in the skin upon exposure to sunlight. It is distinct from vitamin D2 (ergocalciferol), which comes from plants. Vitamin D3 is considered more effective at raising and maintaining vitamin D levels in the bloodstream. Vitamin D is best known for its effects on calcium metabolism and bone health.
