Cosmetics
Anti-aging:L-carnosine has an antioxidant effect. It can scavenge free radicals, prevent the cross-linking of collagen, and slow down the aging process. It is often used in anti-aging serums, lotions, creams and other products for the eyes and face.
Anti-glycation: Its structure is similar to the glycation sites of proteins. It can prevent protein glycation, neutralize carbonyl groups, prevent the formation of damaging cross-links, and reduce the harm of glycation reactions to the skin, keeping the skin firm and shiny.
Food Industry
L-carnosine is an ideal food antioxidant. It can effectively inhibit the free radical reactions of unsaturated fatty acid glycerides in food, prevent the generation of peroxide values and aldehyde substances, ensure food safety, extend the shelf life of food, and has high safety.
Medical and Health Care
Antioxidant stress: As a multi-functional antioxidant active substance, it can stably protect cell membranes and inhibit intracellular peroxidation reactions. Its antioxidant capacity is stronger than that of traditional antioxidants such as vitamin C.
Improving peptic ulcers: The zinc-carnosine complex can effectively maintain the integrity and natural protection mechanism of the stomach, promote the healing of wounds such as gastric ulcers and duodenal ulcers, and also has an improving effect on gastroesophageal reflux and irritable bowel syndrome.
Immune regulation: It is the only physiologically active substance with immune regulation effects discovered so far and can be used to treat various immune diseases and diseases caused by immune abnormalities.
Neuroprotection: It is beneficial to brain health. It can delay the age-related degeneration of brain cells, improve memory and attention, and has potential value in preventing and treating neurodegenerative diseases. It can also relieve the symptoms of autism, although some of the effects still need to be further confirmed by the mainstream medical community.
Sports health care: It helps control muscle contraction, buffers lactic acid, delays muscle fatigue, improves muscle endurance; it can also prevent muscle tissue damage, inhibit the decomposition of muscle proteins by relevant enzymes, and promote protein synthesis and maintenance. It can be used as a sports nutrition supplement by athletes and fitness enthusiasts.
