Energy balance

Beta-alanine supplementation (3-6 g/day for 4-8 weeks) delays fatigue in weightlifting by increasing muscle carnosine levels and buffering acidosis.

Take 3-6 grams of beta-alanine daily for at least 4 weeks to build up muscle carnosine. Split the dose (e.g., 2 grams twice a day) to avoid the harmless tingling sensation.

Beta-alanine increases carnosine levels in skeletal muscles, which plays a key role in reducing the accumulation of hydrogen ions (H+) during high-intensity exercise... thereby delaying the onset of acidosis-induced fatigue.
