What is a2 vitamin?

Vitamin A2, also known as Dehydroretinol, is a less commonly found form of Vitamin A that is synthesized by animals, as opposed to plants. It is found primarily in animal products such as organ meats, butterfat, and eggs from pasture-raised hens. Its chemical structure is slightly different from that of the more commonly known Vitamin A1 (Retinol), and it is also less stable.

Vitamin A2 functions similarly to Vitamin A1, playing a critical role in maintaining healthy vision, skin, and immune system function. It also acts as an antioxidant, protecting the body from the damaging effects of free radicals.

There is some evidence to suggest that Vitamin A2 may be more readily absorbed and utilized by the body than Vitamin A1, but more research is needed to confirm this. Additionally, some people may be able to better tolerate Vitamin A2 than Vitamin A1 due to differences in their genetics or digestive systems.

Overall, while Vitamin A2 is not as widely studied or available as Vitamin A1, it still provides important health benefits and can be obtained through a diet rich in animal products from healthy, pasture-raised animals.
