Heritage & History
American Health was founded in 1987 in Ronkonkoma, New York with a commitment to manufacturing nutritional supplements in the United States to quality standards that the founders felt were not being met by imported alternatives. The supplement industry had grown rapidly but quality control varied enormously, and American Health's founders believed that domestic GMP-certified manufacturing was the answer.
The company became known particularly for Ester-C, a patented calcium ascorbate form of vitamin C that is gentler on the stomach than standard ascorbic acid and is metabolized more slowly for longer-lasting blood levels. Ester-C became one of the most recognized vitamin C innovations in the supplement market, and American Health built a substantial product portfolio around it alongside probiotic supplements and multivitamins.
Made in Ronkonkoma, New York
American Health products are manufactured in their GMP-certified facility in Ronkonkoma, New York, on Long Island. The manufacturing process follows Current Good Manufacturing Practices (cGMP) established by the FDA, including testing of raw materials, in-process quality checks, and finished product testing before release. The New York facility allows American Health to maintain direct oversight of formulation and quality.
The product line includes Ester-C supplements in capsule, tablet, and chewable forms; probiotic supplements with multiple Lactobacillus and Bifidobacterium strains; and a range of vitamins and minerals. American Health products are available at natural food stores, vitamin specialty retailers, and online. For consumers who have been burned by supplement brands with quality issues and want the additional assurance of domestic GMP manufacturing, American Health offers a New York-made alternative backed by decades of production experience.
