L-Carnosine is a dipeptide composed of beta-alanine and histidine, which can inhibit many biochemical changes caused by aging.L-carnosine is a dipeptide of the amino acids β-alanine and histidine, which has the potential to inhibit many of the biochemical changes that accompany aging [1]. Carnosine also has some antioxidant effects. The antioxidant mechanism of carnosine is attributed to its chelation of metal ions, superoxide dismutase (SOD)-like activity, and ROS and free radical scavenging capabilities [2].
