What is Biotin?
Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin essential for metabolizing fats, carbohydrates, and proteins. It's often marketed as a beauty supplement due to its role in maintaining healthy hair, skin, and nails.
Hair, Skin, and Nails
Biotin is a cofactor for carboxylase enzymes involved in synthesizing fatty acids and amino acids needed for keratin production—the protein that makes up hair and nails. Deficiency can lead to brittle nails and hair loss.
Metabolic Function
Beyond beauty, biotin plays a crucial role in energy metabolism, helping your body convert food into usable fuel. It's also involved in gene expression and cell signaling.
Food Sources
Egg yolks, organ meats, nuts, seeds, and legumes are good dietary sources. Note that raw egg whites contain avidin, which binds biotin and prevents absorption—cooking neutralizes this effect.
Supplementation
While biotin supplements are popular for hair growth, benefits are most pronounced in those with actual deficiency. High-dose biotin can interfere with certain lab tests, so inform your healthcare provider if supplementing.
