NAI’s core operations include formulating, manufacturing, and marketing nutritional supplements. Based on its public descriptions, the company offers vitamins, minerals, herbs, and other nutritional supplements, as well as other healthcare products, to customers that market and distribute these products under their own brands. The Private-Label Contract Manufacturing segment provides manufacturing services to companies that sell nutritional supplements and related healthcare products, while the Patent & Trademark Licensing segment generates royalty income from license and supply agreements associated with the sale of branded ingredients.

Business Segments and Revenue Drivers

NAI reports that it operates through two main business segments: Private-Label Contract Manufacturing and Patent & Trademark Licensing. The company states that it derives the majority of its revenue from private-label contract manufacturing, where it manufactures nutritional supplements and other healthcare products for third-party brand owners. These customers then market and distribute the finished products to consumers in various markets.

The Patent & Trademark Licensing segment is associated with NAI’s branded ingredient business, primarily centered on CarnoSyn® beta-alanine and related products. NAI receives royalty, licensing, and raw material sales revenue from license and supply agreements tied to CarnoSyn® beta-alanine and its derivatives. Company press releases also highlight the development and commercialization of TriBsyn™, described as a carnosine booster derived from CarnoSyn® beta-alanine and formulated using proprietary technology.

CarnoSyn® Brands and TriBsyn™

NAI reports that CarnoSyn® Brands feature three clinically studied, patented and patent-pending ingredients available exclusively from the company: CarnoSyn® instant release beta-alanine powder, SR CarnoSyn® sustained release beta-alanine tablets, and TriBsyn™ powder. Public disclosures state that TriBsyn™ is a patent-pending formula that utilizes proprietary technology to increase beta-alanine bioavailability and absorption while effectively eliminating the common paresthesia sensation associated with efficacious dosages of beta-alanine.

In a published clinical study summarized by NAI and CarnoSyn® Brands, TriBsyn™ is described as an encapsulated low-dose beta-alanine complex that increased plasma beta-alanine concentrations compared to conventional beta-alanine, with reported elimination of paresthesia in the study group receiving TriBsyn™. NAI indicates that TriBsyn™ is positioned as a carnosine booster with applications in dietary supplements, medical foods, and other fortified food products, with a focus on areas such as muscle vitality, cognitive performance, and healthy aging.
