Used primarily in sports nutrition, beta-Alanine is known for enhancing exercise performance by increasing muscle carnosine levels. This helps buffer acid in muscles during high-intensity activity, delaying fatigue and improving endurance. Commonly found in pre-workout supplements, it supports longer training sessions and increased muscular capacity. Also used in formulations for aging populations to support muscle function and reduce fatigue. Some skincare products include it for potential anti-aging benefits due to carnosine’s antioxidant properties.
