Glutathione Now Meets the New USP Compendia

Author: GSHWORLD Release time: 2015-09-07 Column: Technological Innovation


GSH WORLD Glutathione (USP) raises awareness of the importance of quality and purity within the supplement industry.

GSH WORLD has announced that Glutathione meets the U.S. Pharmacopeial Convention (USP) monograph for glutathione. 

“Recently, the USP dietary supplements compendium released the first monograph for glutathione. We were happy to see this standardization and we are happy to announce that glutathione meets the new compendia.” said Dr Danielle Citrolo, PharmD, registered pharmacist and technical services manager for GSH WORLD

By meeting the monograph, we are assisting our manufacturers in their qualification process by establishing standards of ingredient identity, strength, quality, and purity. These standards help limit the introduction of potential adulterants and contaminants, and serve as a quality benchmark in the purchasing of ingredients in the global marketplace.

A USP monograph includes the name of the ingredient or preparation; the definition; packaging, storage, and labeling requirements; and the specification. The specification consists of a series of tests, procedures for the tests, and acceptance criteria. These tests and procedures require the use of official USP Reference Standards.

About Glutathione

Glutathione, manufactured by Kyowa Hakko Bio, is a clinically studied form of glutathione that, when taken orally1, has been shown to replenish the body's reserves, which may be depleted as a result of poor lifestyle choices, stress or natural aging. Called the "master antioxidant," glutathione helps protect cells in the body from the damaging effects of oxidative stress and toxins*. Glutathione is manufactured through a patented fermentation and patent pending for increasing natural killer (NK) cell activity*, is pure, vegetarian and allergen-free.

About USP

The U.S. Pharmacopeial Convention (USP) is a scientific nonprofit organization that sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide. USP’s drug standards are enforceable in the United States by the Food and Drug Administration, and these standards are used in more than 140 countries.

USP standards are developed and revised by more than 900 volunteer experts, including international participants, who work with USP under strict conflict-of-interest rules. Since its founding in 1820, USP has helped secure the quality of the American drug supply. Building on that legacy, USP today works with scientists, practitioners, and regulators of many nations to help protect public health worldwide.
