Natural Alternatives International (NAI) is a contract manufacturer of private-label nutritional supplements, including vitamins, minerals, and herbs. NAI manufactures products to customer specifications in capsule, tablet, chewable, and powder formats, while customers handle their own marketing and distribution across direct sales, e-commerce, and retail channels. Along with manufacturing, NAI provides bundled services such as custom formulation, regulatory assistance, packaging design, and clinical study support. The company operates manufacturing facilities in California and Switzerland. In addition to contract manufacturing, NAI owns a patent estate for beta-alanine, an amino acid ingredient used in sports nutrition and wellness. Through this business, NAI sells raw materials and licenses related patents and trademarks under the CarnoSyn brand family. NAI's contract manufacturing revenue depends on customer order volumes, manufacturing capacity utilization, and input costs for raw materials, while its licensing segment generates revenue from royalties, licensing fees, and direct ingredient sales. NAI's strategy focuses on expanding its manufacturing customer base and broadening beta-alanine applications into general wellness and healthy aging markets.
