L-Carnosine is widely used in anti-aging skincare products due to its ability to combat glycation, a process that damages proteins and contributes to skin aging. It helps maintain skin elasticity and reduces the appearance of fine lines and wrinkles. In dietary supplements, L-Carnosine supports cognitive health and neurological function. It acts as a neuroprotective agent, potentially improving memory and focus, and is studied for its role in managing age-related cognitive decline. It is also utilized in sports nutrition for its potential to buffer muscle acidity during intense exercise, thereby delaying fatigue and improving physical performance. In the food industry, L-Carnosine serves as a natural preservative, extending shelf life by inhibiting oxidation and protecting against spoilage. Research explores its benefits in managing diabetes complications, as it may protect tissues from high blood sugar damage, particularly in the eyes, kidneys, and nerves.
