Also called vitamin B7, B8 or H, the biotin It is a vitamin of group B, which plays a prominent role in the metabolization of proteins, carbohydrates and fats, deriving its name from the Greek word “biotos”, which can be translated as “life” or “sustenance”.

In this way, direct reference is made to the role of biotin in releasing the energy stored in food, which helps preserve the life of the body’s cells.

This water-soluble vitamin, which is therefore not stored in the body, requires, due to this characteristic, a regular and constant consumption, to avoid a deficit of it.

Among the main sources of biotin we have foods such as oats, nuts, milk, rice and cheeses, as well as others a little specific such as carrots or mushrooms.

In certain circumstances, it is even advisable to take it through supplements, either with a single ingredient, in this case biotin itself, or within a multivitamin alternative.

Although the biotin requirements of our body will depend on the state of health, age and lifestyle that we lead, it is advises a maximum of 450 mcg daily of this vitamin.
