  • Thorne Research Beta Alanine-SR is an amino acid that supports the muscles during activity.
  • Supports the buffering capacity of muscles
  • Increases carnosine levels in muscles
  • Helps maintain and promote muscle endurance and power output
  • Helps improve time-to-exhaustion during aerobic and anaerobic exercise
  • Provides antioxidant support
  • PureTab™ sustained-release delivery maximizes benefits while minimizing potential tingling
  • The amino acid beta-alanine is a rate-limiting cofactor required for the creation of carnosine, which is responsible for buffering hydrogen ions that are created during energy production in the muscle.
  • Carnosine helps maintain normal pH in the muscle, since acidity is a major contributor to muscle fatigue. Oral carnosine is poorly absorbed in all humans, and tends to be lower in females and those who limit animal proteins in the diet.
  • Sustained-release beta-alanine supplementation has been shown to increase carnosine concentrations in the muscle.* Supplementation with beta alanine supports muscle health, muscle work capacity, and perceived time-to-exhaustion in both anaerobic exercise lasting one to four minutes and aerobic exercise lasting greater than four minutes.*
  • Beta-alanine has also been shown to benefit athletic performance.*
  • For example, studies have shown improvements in fatigue in cyclists, 2,000 meter rowing time trials, strength in college football athletes, and sprint performance in endurance cyclists.*
  • Carnosine also has a role as an antioxidant, limiting the accumulation of free radicals from oxidation of lipid membranes.* PureTab™ sustained-release delivery system minimizes tingling sensations and poor absorption associated with doses of non-sustained release beta-alanine above 800 mg. Beta Alanine-SR is NSF Certified for Sport®.
