Our formulas utilize Vitamin D3 (Cholecalciferol). D3 naturally synthesizes in your skin during exposure to sunlight and it’s also a commercially prepared supplement made from the lanolin retrieved from washing lambs’ wool.

(Note: This form of vitamin D is considered okay for vegetarians because the animals are not killed. If it comes to a choice between the commercial formulas and the small amount of vitamin D3 in our formula, vegans will have to make that decision for themselves.  Other than the D3, our formulas are vegan.)
