Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.
Vitamin D is responsible for proper absorption of calcium, so you need lots of this vitamin every day for optimal bone strength. Vitamin D-3 is the form found in many supplements and most foods that are rich in vitamin D, and it's the kind your body makes when you get sun exposure. Although D-3 is beneficial, too much can lead to toxic effects.
