A single drop of Super Daily D3 delivers the health benefits of vitamin D3 in a range of doses for adults or a 400 IU dose for babies and kids. It promotes teeth, bone, and muscle health; immune and cardiovascular system function; and calcium absorption, the press release says. The drops are vegetarian, non-GMO, dairy-free, and unflavored. Carlson uses a unique single drop delivery system that provides the exact recommended dose, while removing the risk of contamination that can occur with standard droppers.
