About American Health
American Health has been manufacturing vitamins, Ester-C supplements, and probiotics in Ronkonkoma, New York since 1987, operating a GMP-certified domestic facility dedicated to supplement quality.
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.
