Beta-alanine is widely used in the sports and fitness industry as a dietary supplement to enhance athletic performance. It increases carnosine levels in muscles, which helps buffer acid buildup during high-intensity exercise, delaying fatigue and improving endurance. This makes it particularly beneficial for activities like sprinting, weightlifting, and interval training.

In the medical field, beta-alanine is being studied for its potential role in improving muscle function and reducing symptoms in conditions like aging-related muscle loss and chronic fatigue. It may also support recovery in patients undergoing physical rehabilitation.

Additionally, beta-alanine is used in cosmetic formulations for its antioxidant properties, helping to protect skin from oxidative stress and improve overall skin health. Its versatility across fitness, health, and skincare highlights its broad range of applications.
