Vitamin B7, also known as biotin or vitamin H, is a water-soluble vitamin that plays a key role in several important cellular processes. It is a cofactor for several enzymes involved in the metabolism of carbohydrates, proteins, and fats. It also plays a role in the synthesis of fatty acids and the production of glucose.
Biotin is involved in the production of energy in cells, and it also helps to maintain healthy skin, hair, and nails. Additionally, biotin is involved in the regulation of gene expression, and it plays a role in the development of the nervous system.
Biotin is found in a variety of foods, including egg yolks, liver, kidney, nuts, and legumes. The body is also able to produce biotin through the activity of bacteria in the gut. Biotin deficiency is rare, but it can occur in individuals who consume large amounts of raw egg whites or who have certain genetic disorders. Symptoms of biotin deficiency can include hair loss, skin rash, and neurological symptoms such as depression and fatigue. Supplementation with biotin can be beneficial for individuals with biotin deficiency or for those with certain health conditions, such as diabetes or pregnancy.
