Support Your Bones With This Delicious, Vegan D3 Gummy. D3, or cholecalciferol, is the same kind of vitamin D that your body naturally produces, here in vegan, gummy form. Very few foods in nature contain vitamin D and most all D3 supplements are sourced from lanolin — the fat of lamb's wool. MaryRuth's D3 gummies, with three flavors in one bottle — strawberry, lemon, and orange — are made from non-GMO, vegan lichen! Vitamin D is an essential vitamin that aids the body in absorbing phosphorus and calcium, promoting a healthy immune response and maintaining normal bone health, as well as supporting muscle function.
