what is the difference between vitamin d's
There are two different forms of vitamin D: vitamins D-2 and D-3. Vitamin D-2, or ergocalciferol, is the form made by mushrooms from exposure to sunlight. Vitamin D-3, which is also called cholecalciferol, is the type thatâs made in your skin. Both types must be converted into the hormone calcitriol before theyâre active and able to benefit your body.
