KOHJIN Life Sciences, a Mitsubishi Corporation Group Company, began its pioneering research on Glutathione nearly 50 years ago, first establishing it as an active pharmaceutical ingredient (API) for acute detoxification in Japan. KOHJIN’s high-quality Glutathione "OPITAC™" for food & nutrition grade is the only ingredient of its kind to hold U.S. FDA-Notified FULL GRAS status (GRN #000293), is HALAL (MUI #00310028570304/JAKIM #0100-01-147707) and KOSHER (KC #3721936-1) certified, and was the first to achieve JP & USP monograph designation.
