b-Hydroxyisovaleric Acid is a metabolite of the essential amino acid Leucine and is synthesized in the human body. Studies suggest that b-Hydroxyisovaleric Acid may have an effect on increasing muscle weight and strength. The presence of elevated b-Hydroxyisovaleric Acid is a sensitive marker of biotin deficiency and may indicate the presence of a genetic disorder such as biotinidase deficiency or holocarboxylase synthetase deficiency.
