Not all of them contain those additives [1] (I believe coconut oil is needed because cholecalciferol is not water soluble), but yes, I agree that they should not be pushed as a substitute for sunlight if you have the choice: > Each concentrated drop delivers 400IU of vitamin D3, the form naturally found in the body, blended with premium quality fractionated coconut oil. The sugarless formula has no artificial colours, flavours, or preservatives, so it won't interfere with feeding.
