Jarrow L-Carnosine is a dietary supplement that supports healthy aging and cellular renewal by inhibiting glycation and damage caused by free radicals. L-carnosine is a type of dipeptide found naturally in the skin, heart, muscles, brain, and other tissues. It helps reduce glycation, the uncontrolled crosslinking of sugar molecules to proteins, which can lead to loss of cell function and accelerate aging. L-carnosine is also beneficial because it prevents oxidative stress caused by free radicals. Plus, it supports healthy cognitive function by reducing lipid peroxidation and keeping cell membranes stable in the brain.
