A doctor has provided 1 answer
Vitamin D3: Vitamin D2 is synthesized by plants and Vitamn D3 by humans when skin is exposed to ultraviolet B rays from sunlight. The Vitamin D2 and D3 are used by the kidneys to synthesize calcitriol , which is the active form in the body. Vitamin D3 is better utilized in the body than Vitamin D2. Therefore it is recommended to use Vitamin D3. Recommended daily dose varies depending on age.
