Indications

Biotin is used for hair loss, for nails that are weak, brittle, splitting or soft, and for eczema and dermatitis.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Biotin, also called vitamin H, is an essential vitamin. The body needs it for fatty acid synthesis, amino acid catabolism and gluconeogenesis. It works as a cofactor in the enzymatic carboxylation of pyruvate and acetyl-CoA.

Biotin influences the growth and differentiation of epidermal cells, so it matters for the formation and renewal of skin, hair and nails. In hair roots it acts as a coenzyme for mitochondrial carboxylases and improves the keratin structure. When biotin is lacking, hair loss can occur, along with a number of systemic symptoms such as dermatitis and aciduria. Biotin is one of the most prescribed nutritional supplements for any kind of hair loss.
