Add To Cart
Klean SR Beta-Alanine delays fatigue, supports muscle endurance, and supports exercise capacity during short periods of intense effort. The ingredient SR Carnosyn® is a clinically researched, sustained-release formula that simplifies daily dosing and enables better muscle retention, with fewer side effects and simpler dosing than standard beta-alanine. Train harder, stronger and more effectively with Klean SR Beta-Alanine today!*

When you perform high-intensity exercise, hydrogen ions surge into your muscles (often referred to as lactic acid buildup), causing the “burn” you’re all too familiar with and hindering muscle performance.

So you rack the weights, slow down, or take a break and try to ignore the thought that if you could just push just a little harder, for a little longer, maybe you could speed up your gains and improve your performance.

At least, that’s how it usually goes—but not if beta alanine has anything to say about it.

As a supplement with an impressive list of performance benefits that’s gaining popularity quickly, beta alanine is an amino acid that has been shown to help boost work capacity at high intensities and short durations.

By increasing carnosine, a naturally occurring compound found in muscle tissue, beta alanine supports buffering of lactic acid, the cause of the “burn” you feel during exercise, delay fatigue, and boost work capacity by up to 15%.

In other words, for activities requiring repeated bouts of high intensity output like sprinting, jumping, cycling, martial arts, and strength training (to name a few), beta alanine delivers the extra punch needed to maintain maximum power output longer.

With benefits like these, it’s no wonder beta alanine is making itself a “must have” in every athlete’s or serious gym goer’s nutritional regimen.

Lactate Clearance. The ability to remove lactic acid from the muscle allows for continued contraction, leading to more reps, and thus more overload, which is key for improvements in strength and muscle gain. One study showed that beta alanine supplementation demonstrated a greater lactate clearance when compared to the placebo.

Promote Aerobic Performance. Maximal oxygen consumption - the highest rate of oxygen consumption attainable during maximal or exhaustive exercise - is a cornerstone measurement for aerobic performance and overall fitness. When combined with high-intensity aerobic training, beta alanine supplementation was shown to help support endurance over a placebo.

Increase Resistance Training Volume. Greater resistance training volumes – the amount of reps completed for a given exercise – result in superior increases in muscular size. A study that examined the bench press volumes in football players found that supplementation with beta alanine resulted in increased bench press volumes and lower subjective feelings of fatigue.


There’s no doubt that beta alanine has a place in every athlete or fitness enthusiast’s nutritional strategy, but not all products are created equal. You may have heard or experienced what many athletes describe as a "tingling sensation" from products containing beta alanine. We use a carefully sourced time-release formula that manages to deliver a high caliber of impact to performance without uncomfortable sensations.

Similarly, while many beta alanine supplements out there are packed full of unwanted fillers (like stearates, corn syrup, and hydrogenated vegetable oils), you won’t find any of that stuff here.

Put simply, Klean’s beta alanine has been developed with the highest standards, providing the performance you need and the quality you deserve.

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. Every product that carries the NSF Certified for Sport® mark has undergone stringent laboratory testing to confirm content, purity and compliance
