Klean SR Beta-Alanine

Klean SR Beta-Alanine by Klean Athlete and Douglas Laboratories supports muscle capacity and lessens muscle fatigue to benefit athletic performance. The amino acid beta-alanine supports muscle function by acting as a buffer to delay the onset of muscle fatigue.

Klean SR Beta-Alanine and the entire Klean Athlete line have undergone rigorous testing by the NSF Certified for Sport program which was created to meet the growing demands of athletes, coaches and healthcare professionals to certify that sports supplements are safe and free from banned substances.


  • Supports muscle performance
  • Improves muscular endurance
  • Helps balance pH levels during exercise

Functions and Mechanism of Action

Carnosine (beta-alanyl-L-histidine) is present in high concentrations of human skeletal muscle. The rate limiting precursor in carnosine synthesis is beta-alanine (BA). Hydrogen (H+) ions are produced when lactic acid levels rise during prolonged and intense exercise.

The production of lactic acid can also result in higher acidity within the muscle and decreases the ability of the muscle to contract. BA helps balance pH levels during high intensity exercise. Higher carnosine levels in the muscle buffer the production of hydrogen ions. This allows for the muscle to contract with force and maintain endurance by delaying the onset of muscular fatigue.


2 tablets contain:

  • Beta-Alanine (as SR CarnoSyn) – 1.6 g

Other ingredients: Hydroxypropyl methylcellulose, dicalcium phosphate, corn starch, microcrystalline cellulose, hydroxypropyl cellulose, vegetable stearate, silicon dioxide.

Non-GMO, Gluten-free

Suggested Use

Take 2 Klean SR Beta-Alanine tablets 2 times daily or as directed by a trainer, health coach, or healthcare professional.

Athletes may choose to obtain optimum beta-alanine intake by employing a “loading” phase into their workout regimen by ingesting higher amounts per day for a period of time before reducing the beta-alanine intake amount to a more typical maintenance dose of 3.2 g.

Several peer-reviewed studies have used SR CarnoSyn®to maximize beta-alanine loading with the dosage amounts of up to 6.4 g. Using this patented sustained release formulation, paresthesia is reduced and higher doses of beta-alanine can be ingested.

Side Effects

SR Carnosyn is a sustained release beta-alanine formulation designed to slow absorption, improve body retention, and reduce the sensory sensations in the skin known as paresthesia, a common side effect of beta- alanine consumption.
