WebJan 8, 2024 · Carnosine is a dipeptide (a combination of two amino acids) of beta-alanine, and histidine linked together, a.k.a. beta-alanyl-L-histidine ( 1 ). It’s found in the brain, kidney, and muscles of fish, birds, and mammals (like you and me) although it’s primarily found in red meat ( 2 ). WebIntroduction: Beta-alanine (BA) is a popular ergogenic supplement because it can induce muscle carnosine loading. We hypothesize that, by analogy with creatine supplementation, 1) an inverse relationship between urinary excretion and muscle loading is present, and 2) the latter is stimulated by carbohydrate- and protein-induced insulin action.
