Tongkat Ali extract (Malaysian ginseng) is produced from the root of Eurycoma longifolia, a tropical plant native to Southeast Asia. The root is extracted using hot water or hydroethanolic methods and standardized for quassinoid content, primarily eurycomanone.
Clinical research supports Tongkat Ali's ability to support healthy testosterone levels, improve male fertility parameters, reduce cortisol, and enhance exercise performance and body composition. The extract also demonstrates anti-estrogenic, adaptogenic, and antimalarial properties. Commercially, Tongkat Ali is one of the fastest-growing men's health supplement ingredients, used in testosterone support products, sports nutrition, and vitality formulations.
