Beta Alanine-SR (120tabs) by Thorne

Beta Alanine-SR is NSF Certified for Sport® and the PureTab® sustained-release delivery system minimizes tingling sensations and maximizes absorption.* 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.* Thorne’s Beta Alanine-SR 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 has been shown to benefit athletic performance.* For example, studies show improvements in fatigue in cyclists, in 2,000-meter rowing time trials, in strength in college football players, and in sprint performance in endurance cyclists.* Increasing the level of carnosine also provides an antioxidant effect by limiting the accumulation of free radicals from oxidation of lipid membranes.* The PureTab® sustained-release delivery system minimizes the tingling sensations and poor absorption associated with consuming non-sustained release beta-alanine above 800 mg.

Because an athlete needs to know that his or her supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents.
