L-Carnosine
Based on 2 publication(s) in Google Scholar
L-Carnosine is a dipeptide composed of beta-alanine and histidine. L-Carnosine is an endogenous metabolite found in human brain, muscle and gastrointestinal tissues and is present in all vertebrates. L-Carnosine is a non-enzymatic free radical scavenger and natural antioxidant with anti-inflammatory and neuroprotective properties that can inhibit biochemical changes associated with aging.

L-Carnosine is a dipeptide of the amino acids beta-alanine and histidine and has the potential to suppress many of the biochemical changes that accompany aging[1].
L-Carnosine also exhibits some antioxidant effects. The antioxidant mechanism of L-Carnosine is attributed to its chelating effect against metal ions, superoxide dismutase (SOD)-like activity, and ROS and free radicals scavenging ability[2].
