Vitamin B7 (Biotin)
Vitamin B7 (Biotin)
Overview:
Vitamin B7, commonly known as biotin, is a water-soluble vitamin that plays a key role in the metabolism of carbohydrates, fats, and proteins. It is also important for maintaining healthy hair, skin, and nails.
Sources:
Biotin is found in a variety of foods, including eggs, nuts, seeds, fish, meat, and certain vegetables like sweet potatoes.
Functions:
Metabolism: Biotin acts as a coenzyme for carboxylase enzymes, which are involved in the synthesis of fatty acids, gluconeogenesis, and the metabolism of amino acids.
Hair, Skin, and Nails: Biotin supports the health of hair, skin, and nails, often being used to prevent hair thinning and improve nail strength.
Deficiency:
Biotin deficiency is rare but can lead to symptoms such as thinning hair, skin rashes, conjunctivitis, and neurological issues like depression and lethargy. Certain conditions, like biotinidase deficiency, can increase the risk.
Toxicity:
Biotin is generally considered safe, with no known toxicity. Excessive intake from supplements does not appear to cause adverse effects due to its water-solubility and the body’s ability to excrete it efficiently.
