Biotin is a water-soluble B vitamin typically found in liver,
egg yolk, cereals, legumes and nuts. In the body, biotin
is found in low concentrations in the brain, liver and muscle
tissue. Biotin is utilized to synthesize intracellular carboxylase
enzymes and is essential for normal skin and hair growth.
The various carboxylase enzymes are important for lipid
metabolism and energy production (ATP) via synthesis of
oxaloacetate. Alcohol decreases biotin status in the body.
