Biotin, also known as vitamin B7, is a water-soluble vitamin that helps the body convert food into energy. It plays an important role in the health of skin, hair, nails, and the nervous system. Biotin can be found in a variety of foods, including eggs, milk, nuts, and legumes, and it can also be taken as a supplement. Biotin supplements are used to treat a number of conditions, including hair loss, brittle nails, and diabetes. Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin that plays a vital role in several bodily functions, including:
Metabolism: Biotin acts as a coenzyme, assisting enzymes involved in: * Carbohydrate metabolism: Converting carbohydrates into usable energy (glucose). * Fat metabolism: Breaking down fats for energy production. * Protein metabolism: Helping the body utilize amino acids, the building blocks of proteins.
Cell growth and proliferation: Biotin is essential for the normal growth and division of cells.
Other functions: Biotin also contributes to: * Maintaining healthy hair, skin, and nails. * Regulating gene expression. * Supporting proper nervous system function.
Sources of Biotin:
Biotin is naturally found in a variety of foods, including:
- Eggs (especially egg yolks)
- Organ meats (liver, kidney)
- Nuts and seeds (almonds, peanuts, sunflower seeds)
- Bananas
- Avocados
- Cauliflower

Deficiency and Supplementation:
Biotin deficiency is uncommon, but it can occur in individuals with:
- Poor diet: Lack of a balanced diet containing biotin-rich foods.
- Certain medical conditions: Affecting intestinal absorption or biotin metabolism.
- Long-term consumption of raw egg whites: Raw egg whites contain a protein called avidin, which binds to biotin and prevents its absorption.
