There are many types of vitamins in daily life, and the body needs a large amount of vitamins to maintain normal needs. However, different types of vitamins have different differences in supplementation. So, what is the difference between Vitamin D2 and D3?

There are two common types of Vitamin D, including Vitamin D2 and D3. Vitamin D2 belongs to calciferol, and Vitamin D3 belongs to cholecalciferol. Regardless of which one, they all belong to specific substances and need to be converted by renal and liver cells to promote the absorption of calcium and phosphorus in the colon. When there is a deficiency of these two vitamins, the body’s ability to absorb calcium and phosphorus will decrease, thereby affecting the body to a certain extent.

When Vitamin D2 and D3 are shown in specific situations, their functions are the same, both can promote human growth and development and the intake of nutrients, but their sources are different. Vitamin D2 is obtained from food or green plants, while D3 is naturally produced through the skin after direct sunlight exposure.

Vitamin D2 and Vitamin D3 differ not only in appearance, Vitamin D2 is a colorless, milky white crystal, while Vitamin D3 is a crystal. Regardless of which vitamin D is taken, it cannot be digested and absorbed in time in the body and is excreted with feces. Therefore, it should be taken after meals to be better digested and absorbed by the body.
