D3 vs. D2- Which Form is Better?

Vitamin D3, also known as cholecalciferol, is the biologically active form of Vitamin D. It is found in animals, and supplements containing it often source from things such as lanolin and fish liver oil, but it is also found in egg yolks, butter, and liver. Vitamin D2 is known as ergocalciferol, and is the inactive form that is found in plants such as mushrooms or fortified grain products. Studies have shown that vitamin D3 is 87% more bioavailable than vitamin D2, as it can be readily utilized by the body and does not need to be converted, thus, if you do not follow a vegetarian/vegan diet, vitamin D3 is recommended. *Vegan forms of vitamin D3 are sourced from lichen, a composite organism that is both a fungus and algae.
