For decades, CarnoSyn® has helped everyday and elite athletes train harder and recover faster. CarnoSyn® 4X quadruples bioavailability in a proprietary formula for efficacious dosing without paresthesia.

The proprietary, patent-pending ingredient gives sports nutrition brands a new way to deliver trusted CarnoSyn® beta-alanine benefits to a wider audience with greater efficiency, improved user experience, and lower cost-in-use potential.

“The CarnoSyn® brand name has stood for trusted performance in sports nutrition for more than 20 years, and CarnoSyn® 4X represents the next evolution of that legacy,” said Kenneth Wolf, President and Chief Operating Officer of NAI. “CarnoSyn® 4X gives formulators a way to expand the beta-alanine audience, reaching consumers who may have avoided it because of the tingling sensation, while reinforcing the CarnoSyn® name as a trusted on-pack signal of performance.”

Backed by more than 55 clinical studies, the CarnoSyn® portfolio remains the only beta-alanine with New Dietary Ingredient (NDI) status. This innovation gives sports nutrition brands flexibility to pursue line extensions and launch new products featuring beta-alanine across more usage occasions and consumer needs. CarnoSyn® Brands continues to build on its leadership in performance nutrition by delivering clinically supported beta-alanine solutions that meet the evolving needs of brands and consumers alike.
