Our pure liquid vitamin D3 is sourced from lichen, an organism that arises from algae. Unlike traditional vitamin D3 supplements sourced from lanolin, we can assure you are getting the purest, more natural vegan source of D3 from our drops. Vitamin K2 ensures that the calcium is transported to your bones where it is needed most. Our vitamin D3 drops do not contain any sugar, salt, starch, wheat, gluten, yeast, milk, soy derivatives or artificial preservatives. 1000 IU of Vitamin D3 made from lichen (plant-based) and 45 mcg of Vitamin K2 - 2 month supply Other ingredients: MCT Oil Organic (from coconut oil) 2 oz.
