Vitamin A - Everything you need to know

In the following you will learn everything important about vitamin A. Among other things, how much you should take and which foods belong to the vitamin A suppliers. Did you know that vitamin A plays an important role in the visual process?

What is vitamin A?

Vitamin A, like vitamins D, E and K, belongs to the group of fat-soluble vitamins. It is absorbed into the blood in the small intestine through food and can be stored in the liver. There are also different forms of vitamin A, such as retinol, retinal, retinoic acid or beta-carotene. Beta-carotene, however, is only considered a precursor to vitamin A. This is then converted into active vitamin A in the body.

What foods contain vitamin A?

Vitamin A, like many other vitamins, can be absorbed through food. Foods of animal origin, such as liver, sea fish, eggs, milk and dairy products, are particularly rich in vitamin A. Foods of plant origin are rich in beta-carotene. This is often found in large quantities in carrots, spinach, broccoli, cherries, grapefruit or peppers, but our One Bear A DAY vitamins also contain this important vitamin.

What are the benefits of taking vitamin A?

Vitamin A plays a very important role in the visual process. It is part of the retina, which is responsible for distinguishing between light and dark.
In addition, vitamin A has a positive effect on the reproductive process, as it is essential for the production of testosterone, for the development of the placenta and for the maturation of the foetus.
Vitamin A is also needed for bones and teeth. In the cosmetics industry, it is used in creams and serums to build and regenerate the skin. Retinol, in particular, is a component of many cosmetic products because it is converted to retinoic acid in the skin. It is reported to improve skin elasticity.
Beta-carotene, on the other hand, has an antioxidant effect, protecting cells from oxidative stress known as free radicals. These include UV rays, exhaust fumes and other harmful factors.


"Vitamin A is mainly involved in growth, cell formation, reproduction and vision. In addition, vitamin A is also one of the antioxidants that protect cells from oxidative stress. That's why it's so important to take, and it's important not to miss out."
