Thorne Vitamin D3 delivers liquid vitamin D3 with a precision bulb dropper that measures 2,000 or 4,000 IU precision doses. Because many individuals don't get enough vitamin D from sunlight, diet, or lifestyle, supplementation is essential — and vitamin D3 is more potent and better absorbed than the D2 form. The vegan, sustainably-sourced D3 pairs with a clean MCT oil base preserved with natural vitamin E.*
