NAI launches CarnoSyn 4X beta-alanine with four-times greater bioavailability and no paresthesia

Published: 22-Apr-2026

The brand has introduced a new patent-pending beta-alanine formulation delivering more than four times the bioavailability of standard beta-alanine without the tingling sensation that has historically limited broader consumer adoption of the ingredient

Natural Alternatives International (NAI) has announced the launch of new ingredient CarnoSyn 4X, calling it the "most advanced CarnoSyn beta-alanine formulation to date."

The company stated in its announcement that the ingredient delivers more than four times the bioavailability of standard beta-alanine and, crucially, does so without paresthesia, the tingling sensation often associated with beta-alanine usage.

NAI added that the patent-pending ingredient offers sports nutrition brands a new way to effectively deliver the trusted benefits of CarnoSyn beta-alanine to a broader audience while enhancing user experience and reducing costs.

"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.

With more than 55 clinical studies backing it, the CarnoSyn portfolio is the sole beta-alanine product with New Dietary Ingredient (NDI) status. This allows sports nutrition brands to expand their product lines and meet diverse consumer needs.
