3-Methylhistidine

3-Methylhistidine (3-MH) is a post-translationally modified amino acid which is excreted in human urine. Urinary concentration of 3-methylhistidine is a biomarker for skeletal muscle protein breakdown in humans who have been subject to muscle injury. Urinary 3-methylhistidine concentrations are also elevated from consumption of soy-based products and meat, particularly chicken.
