Unparalleled quality
and consistency —
produced in Japan
Located in every cell of our body, Glutathione is a tripeptide comprising glutamic acid, cysteine, and glycine.
Time exposes the body to toxins and pollutants from inside and out. These, along with health, stress, and other factors can contribute to immune system deficiency.
As we age, the volume of glutathione maintained in the body reduces dramatically, and can benefit from supplementation.
OPITAC™ Glutathione is L-Glutathione Reduced, widely noted for having antioxidant activity. As a supplement it’s taken to support detoxification, to brighten complexion,
and to maintain liver health and immune system strength.
OPITAC™ Glutathione is produced by KOHJIN Life Sciences, a subsidiary of Mitsubishi Corporation Life Sciences, which has been producing it consistently in GMP-certified manufacturing facility in Japan.
*As of November 1, 2023
OPITAC™ Glutathione is produced in KOHJIN Life Sciences facilities, located in Oita Saiki city in Japan.
KOHJIN Life Sciences was established at the Saiki Plant in 1962, beginning with yeast production through the fermentation of wood molasses. Since then, over half a century it has continued to improve the technologies related to microbial fermentation, with yeast serving as the core product, mainly for food ingredients and pharmaceuticals.
Breakthrough clinical findings proving that OPITAC™ Glutathione is absorbed in the human body by oral ingestion were first published following a study conducted in 2013 in collaboration with a team from Kyoto Prefectural University and Kyoto University.
Since then, this has been reaffirmed and expanded on in repeated peer-reviewed clinical studies.
Glutathione is a naturally-occurring tripeptide that is produced in the human body. OPITAC™ Glutathione is the world’s only glutathione that has been notified to the U.S. Food and Drug Administration (FDA) as GRAS.
OPITAC™ Glutathione is derived from torula yeast, which is also approved by the U.S. FDA as edible yeast.
At least 100, and up to 500, milligrams daily, depending on the application and regulations applying in each country. Please contact us for more information.
It was inspired by the words “optimize” and “intact”.
Optimize, because the underlying mission guiding all of Kohjin’s research and development, as well as the fundamental function of glutathione in the body, is the optimization of health.
“TAC” commemorates the breakthrough human clinical study establishing single-dose, intact bodily absorption of glutathione for the first time, in 2013.
