Meet the new generation of
NFL hopefuls who use
CarnoSyn® to help them
achieve their gridiron dreams.




CarnoSyn® is the go-to ingredient in sports nutrition formulas, proven by science to extend endurance, speed recovery time and build more muscle, faster. CarnoSyn® beta-alanine is a naturally occurring amino acid that works as a buffer to delay the onset of muscle fatigue and failure.

Manufactured under a strict quality control process, CarnoSyn® contains clean ingredients and ZERO banned substances.


Load, Dose & Stack for Success

CarnoSyn® can help YOU build more muscle, recover faster and reach your athletic goals – but only if you load and dose the right amount. Make sure you know how much is required to achieve peak performance, and how and when to properly stack CarnoSyn® for proven results.

Look for the CarnoSyn® Logo

The Top Sports Nutrition Brands Trust CarnoSyn® and ONLY CarnoSyn® beta-alanine for their products. Confirm safety and quality - always look for the CarnoSyn® logo on your pre- and post-workout formulas.



How does CarnoSyn® beta-alanine work?

CarnoSyn® beta-alanine is a non-essential amino acid that binds to histidine to form muscle carnosine. Carnosine buffers, or neutralizes, the hydrogen ions (lactic acid) that lead to muscle fatigue and failure.

What’s the difference between CarnoSyn® and SR CarnoSyn®?

The CarnoSyn® brand features two ingredients: CarnoSyn® instant release beta-alanine and SR CarnoSyn® sustained release beta-alanine. Both ingredients deliver the same benefits for athletic performance: increased strength, enhanced endurance, faster recovery, and greater mental focus. Sustained release SR CarnoSyn®, is a new delivery form of CarnoSyn®, which delivers higher dosing levels of beta-alanine. SR CarnoSyn® results in a sustained release beta-alanine that stays in the body longer for carnosine synthesis. The net effect is higher muscle retention of carnosine, facilitating better, faster, muscle-building results.

Does SR CarnoSyn® beta-alanine eliminate paresthesia?

SR CarnoSyn® features a sustained release profile designed to buffer paresthesia associated with instant release beta-alanine. Sensitivity may vary depending upon the individual and the dosage amount and variety of food intake prior to supplementing with SR CarnoSyn®.

Does CarnoSyn® contain any banned substances?

No. CarnoSyn® beta-alanine is safe and contains zero banned substances.

Why is ingesting carnosine directly ineffective?

Ingested carnosine breaks down in the body into beta-alanine and histidine on absorption from the gut and only micro amounts are found in the blood stream. Research has shown that enough histidine is naturally present in the body to meet the demands of muscle for synthesis of carnosine, and that the limiting factor is beta-alanine. Beta-alanine supplementation augments the small amounts available from (1) synthesis in the liver, and (2) from the ingestion of meat and fish. Supplemental beta-alanine combines with the naturally occurring histidine to increase the levels of carnosine.

Can you combine CarnoSyn®/SR CarnoSyn® with other supplements?

Yes. Users can take CarnoSyn® and SR CarnoSyn® beta-alanine alone or in combination with other ingredients.

Why do vegetarians need to supplement muscle carnosine?

Most individuals do not consume enough beta-alanine in their diets to increase athletic performance. And, because beta-alanine is most often found in meat sources, vegetarian athletes can have an even greater need to supplement beta-alanine levels. The synthesis of beta-alanine in the liver, the only source available to vegans, is very low in humans and can only maintain low levels of muscle carnosine.
