Beta Alanine-SR supports muscle capacity and fights muscle fatigue to benefit athletic performance.* Because acidity is a major contributor to muscle fatigue, the presence of carnosine helps maintain a normal pH in muscles by buffering the hydrogen ions created when muscles generate energy.* Beta alanine, an amino acid, is required to create carnosine.* Supplementing with beta alanine will support muscle health, muscle work capacity, and perceived time-to-exhaustion in anaerobic exercise that lasts 1-4 minutes and aerobic exercise that lasts longer than four minutes.*Carnosine's absorption is poor, and tends to be lower in females and in individuals who limit animal protein in their diet. Sustained-release beta-alanine supplementation, such as Thorne's Beta Alanine-SR, has been shown to increase carnosine concentrations in the muscle.* Beta Alanine-SR is NSF Certified for Sport® and the PureTab® sustained-release delivery system minimizes tingling sensations and maximizes absorption.* • Muscle/Tendon* • Sports Performance*
