Beta-Alanine is a non-essential beta amino-acid made with CarnoSyn, a patented ingredient clinically proven to reduce muscle fatigue by counteracting the development of lactic acid, created by an influx of Hydrogen ions (H+). When Beta-Alanine is readily available in the bloodstream, Carnosine levels rise which delay the buildup of H+ ions, translating into delayed muscle fatigue, better strength, endurance, and optimized performance. When you need one more rep, Beta-Alanine will help you get it.
