L-carnosine is crucial for many normal body functions, including the proper function and development of the muscles, heart, liver, kidneys, brain, and many other organs. It plays several important roles in the body, acting as an acid buffer in muscle cells. It may also exert antioxidant activity and has been shown to inhibit lipid oxidation, including the oxidation of LDL and maybe a free radical scavenger. It seems to have the ability to buffer pH activity and appears to delay muscle fatigue. L-carnosine helps promote improved muscle endurance. It is widely used among athletes, bodybuilders, runners, cyclists, and more. Carnosine is also used to inhibit signs of aging and for relieving complications of diabetes such as nerve damage, eye disorders (cataracts), and kidney problems.

The common health benefits of L-carnosine include:

• Acts as an antioxidant [3]
• Improves cognitive function [4]
• Is an anti-aging [5]
• Improves learning and memory [6]
• Reduces stress and depression [7]
• Regulates immune system [8]
• Is an anti-inflammatory [9]
• Helps people fight cancer [10]
• Helps with diabetes [11]
• Helps people who have Alzheimer’s disease and Parkinson’s disease [12]
• Improves blood flow [13]
• Improves heart health [14]
• Enhances physical performance [15]
• Promotes eye health [16]
• Lowers blood pressure [17]
• Helps with autism [18]
• Improves kidney health [19]

L-carnosine helps reduce damaging protein glycation in the body. It has excellent antioxidant properties. It can greatly reduce damage from the highly reactive oxygen free radicals produced from the out-of-control oxidation of lipids and sugar that can occur in Metabolic Syndrome and diabetes. Moreover, this antioxidant effect occurs at concentrations of carnosine known to exist in the human body. In animal studies, the administration of high doses of carnosine reduced oxidative damage in the brain and blood during periods of high stress. In a study using rats made salt-sensitive with stress hormones, intravenous administration of carnosine decreased their blood pressure and reduced sympathetic nervous system activity in their kidneys.
