Acute pre-exercise supplementation of combined carnosine and anserine enhances initial maximal power of Wingate tests in humans.

J Appl Physiol (1985) 2021 Apr 29. Epub 2021 Apr 29.

Department of Movement and Sports Sciences, Ghent University, Belgium.

Classic in vitro experiments (Severin's phenomenon) demonstrated that acute carnosine supplementation may potentiate muscle contractility. However, upon oral ingestion, carnosine is readily degraded in human plasma by the highly active serum carnosinase-1 (CN1). We developed a novel strategy to circumvent CN1 by pre-exercise ingestion of combined carnosine (CARN) and anserine (ANS), the methylated analog with similar biochemical properties but more resistant to CN1.
