PowerBar® High Intensity Sustained Release Beta Alanine dietary supplement provides an even supply of beta-alanine to your muscles. Beta-alanine works by increasing muscle carnosine levels, buffering lactic acid that builds up during high-intensity exercise, which can reduce muscle burn and fatigue. Designed for endurance, team, and strength athletes, these beta-alanine tablets are formulated to help enhance both high-intensity training and performance.
