Biotin

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a crucial role in various metabolic processes in the body. It is essential for the metabolism of carbohydrates, fats, and proteins. Biotin is also important for the health of the skin, hair, and nails.

Functions of Biotin

• Metabolism: Biotin is a coenzyme that helps in the metabolism of carbohydrates, fats, and proteins. It is involved in various enzymatic reactions that convert these macronutrients into energy.
• Skin, Hair, and Nails: Biotin is often associated with promoting healthy skin, hair, and nails. It is involved in the production of keratin, a protein that makes up the structure of these tissues.
• Gene Expression: Biotin plays a role in gene expression and cell signaling, contributing to the regulation of various cellular processes.

Sources of Biotin

Biotin is found in a variety of foods, including:

• Egg yolks
• Nuts and seeds
• Meat (especially organ meats such as liver)
• Fish
• Whole grains
• Legumes

Biotin Deficiency

A deficiency of biotin is rare, but it can lead to symptoms such as hair loss, skin rash, and neurological problems. Certain conditions, such as pregnancy or long-term antibiotic use, may increase the risk of biotin deficiency.
