Vitamin D3 Vegan is a unique formula specifically developed for vegans, strict vegetarians, or for those who prefer a non-lanolin form of vitamin D3. Sourced from lichen, this plant-based liquid formula is in the natural form of vitamin D (cholecalciferol) and is better absorbed and utilized by the body. Natural vitamin D3 helps regulate the body's levels of calcium and phosphorus, increases mineralization in the bones, and helps prevent vitamin D deficiency.* This product does not contain lanolin or fish oil.
