Train harder for longer with support for muscle output and endurance.

Beta Alanine-SR supports your training goals by benefiting muscle output and helping to reduce fatigue and soreness. Sustained-release technology provides long-lasting benefit while minimizing side effects.

Beta alanine, an amino acid, plays an integral role in muscle health and endurance. Beta alanine enables the body to produce carnosine, which is stored in muscle. Carnosine buffers the pH of muscle tissue so it produces energy efficiently without excessive lactic acid buildup, which can cause fatigue and soreness.

Beta alanine is not just for athletes. Beta alanine muscle content also decreases with age. This, combined with powerful antioxidant support, makes Beta Alanine-SR a great option for aging individuals who wish to support muscle health and longevity.

The best food sources of beta alanine are animal protein like meat and fish. Because the best food sources of beta alanine are animal protein, like meat and fish, individuals who are vegetarian or follow a mostly plant-based diet have less carnosine in their muscles compared to individuals who eat more animal protein.
