The Alpha of the Betas

Proven Performance. Scientific Studies. Patent Protection.

CarnoSyn® beta-alanine is a leading ingredient in sports nutrition formulations and the only beta-alanine licensed under NAI's global patent estate for use as a human dietary supplement. Dr. Roger Harris, who changed the sporting world with groundbreaking research and inventions involving creatine, discovered the benefits of using beta-alanine as a human dietary supplement to support an increase in muscle carnosine and athletic performance.* Dr. Harris continues to lead NAI's global efforts to further expand their research and patent estate in the area of beta-alanine.

SR CarnoSyn® - Better, Faster Results!

SR CarnoSyn®, the new sustained release form of CarnoSyn®, has been studied for the past decade and until now was not commercially available in a powder application. SR CarnoSyn® delivers higher levels of beta-alanine more comfortably in a single dose. Higher doses and extended absorption convert to faster increases in muscle carnosine levels for maximum results.* SR CarnoSyn® delivers much higher dosage levels than instant release CarnoSyn® before reaching the typical paresthesia-sensation threshold. The net effect is greater muscle retention of carnosine.

Both CarnoSyn® and SR CarnoSyn® deliver a bio-friendly form of beta-alanine, a naturally occuring beta amino acid essential for the synthesis of muscle carnosine.* Muscle carnosine acts as a buffer, delaying the onset of muscle fatigue and failure. Dr. Harris found that supplementing the body’s beta-alanine stores increased muscle buffering capacity and resulted in greater physical working capacity, enhanced endurance and delayed fatigue.* The patented, scientifically proven uses of CarnoSyn® beta-alanine -- and now SR CarnoSyn® beta-alanine -- as dietary supplements are reshaping the futures of athletes everywhere.*

Backed by hard science, SR CarnoSyn® delivers added benefits:

  • Remains in the body longer to support maximum muscle retention.* 
  • Delivers a higher dose more comfortably. 
  • Elevates muscle carnosine levels with a higher dosage.* 
  • Simplifies daily dosing.
  • Suitable for all paresthesia-sensation thresholds.

Now Anyone Can Build a Better Muscle Faster™

Who can benefit from CarnoSyn® and SR CarnoSyn® beta-alanine? Lactic acid can build up as a result of many activities, from climbing the stairs to high-intensity exercises. Now with SR CarnoSyn® beta-alanine, the benefits are no longer just for athletes or body builders. It is for anybody who feels the burn. SR CarnoSyn® beta-alanine supplementation can benefit all active adults by decreasing the discomfort of muscle burn, delaying muscle fatigue, and maximizing results.* The latest muscle science innovation is SR CarnoSyn®.
