Jarrow Formulas Glutathione Reduced features the primary ingredient of reduced, non-oxidized glutathione, a sulfur-containing tripeptide. Each capsule of Jarrow Formulas Glutathione Reduced contains 500 mg of reduced glutathione. Glutathione Reduced plays a role in balancing the redox potential of cells and regulating detoxification processes.* By supplementing with Glutathione Reduced, you can support your body's natural detoxification mechanisms and cellular balance.* Glutathione Reduced helps protect cells from oxidative stress.* Glutathione Reduced has the ability to support the regeneration of antioxidant forms of vitamins C and E. These vitamins, known for their antioxidant properties, become oxidized during their function. Glutathione Reduced helps convert them back into their reduced, antioxidant forms.* Jarrow Formulas Glutathione Reduced is crafted to meet the needs of various dietary preferences and restrictions. It is Non-GMO, suitable for vegans, and does not contain gluten, making it a versatile and inclusive choice. Take 1 capsule per day with a meal. Jarrow Formulas’ original goal has always remained the same: To design superior dietary supplements that help empower individuals to take charge of their own health.*These statements have not been evaluated by the Food and Drug Administration.

Glutathione (GSH) is a tri-peptide composed of the amino acids glycine, cysteine, and glutamate. As one of the primary protective molecules in the body it is found, inside and outside of cells, in all tissues and body fluids. GSH is most highly concentrated in the liver, spleen, kidney, eye-lens, erythrocytes, and leukocytes. Higher glutathione status and/or dietary intakes have been correlated with cardiovascular, oral and eye health, as well as increased vitality with aging.*
The best food sources of glutathione are fresh fruits and vegetables and newly prepared meats. Since most methods of food processing destroy glutathione, the excessive intake of processed foods may be leading to modern diets that are often devoid of glutathione. Studies evaluating dietary intake from food have found wide variations amongst individuals: 3-250 mg/day (mean: 35 mg/day). Additionally, body-stores tend to decrease with age and even fluctuate throughout the day.
Good By Mouth
Since GSH is a peptide, many assume that it is completely digested by enzymes in the intestines. Further fueling this assumption, early studies did not find an appreciable increase in plasma levels after GSH ingestion. However, it now appears that GSH's uncommon linkage amongst the glutamate side-chain and the cysteine residue makes GSH partially resistant to common peptide cleavage enzymes. This not only impacts its digestion, but also its regulation inside the body. Numerous studies have now demonstrated that oral glutathione is bioavailable and that blood levels may stay relatively constant even as tissue levels rise.
Oral glutathione feeds bodily tissues via three routes 1) absorption intact in the intestines followed by tissue uptake from blood, 2) degradation to its constituent amino acids in the GI tract, cellular absorption, then intracellular GSH re-synthesis, and 3) terminal passage into cells that line the GI tract. The availability of L-cysteine is the bottleneck for glutathione synthesis in the body, since cysteine is the least prevalent of glutathione's three constituent amino acids in the diet. This is one reason N-acetylcysteine (NAC) is also used to support glutathione levels. Overall, there are about 15 grams of GSH in the body, of which roughly four grams can be found in the liver.
RedOx & Detox
GSH is the major endogenous antioxidant produced by the body, possessing a substantial reduction-oxidation (i.e. "redox") potential. Thus it can participate both directly and indirectly in the neutralization of free radicals and reactive oxygen species. It also helps maintain levels of exogenous antioxidants, such as vitamins C and E, in active forms. And of course, GSH is a cofactor for the enzyme glutathione peroxidase, which primarily protects the body from oxidative damage.*
GSH is added to lipophilic toxins, waste and xenobiotics in the liver during phase-2 detoxification to make them water-soluble and allow excretion from the body. As one example, GSH is necessary for the detoxification of methylglyoxal, a toxin produced as a by-product of human metabolism and thought to be a source of advanced glycation end-products (AGEs).* GSH is also necessary to avoid acetaminophen toxicity. In fact, GSH levels are often intentionally bolstered in cases of overdose. GSH keeps the acetaminophen metabolite NAPQI from binding to thiol groups of cellular proteins and causing cell-death.
What's Your G-Ratio?
The ratio of reduced glutathione to oxidized glutathione within cells is often used as a measure of cellular toxicity. In healthy cells and tissue, more than 90 percent of the total glutathione pool is in the reduced form (GSH) and less than 10 percent exists in the disulfide form (GSSG). An increased GSSG-to-GSH ratio is considered indicative of oxidative stress and sometimes tissue dysfunction. Besides a poor diet, other lifestyle factors like smoking cigarettes, excessively consuming alcohol and chronically taking medications can alter the GSSG-to-GSH ratio. If your G-ratio needs work, try Jarrow FORMULAS Glutathione Reduced.
