1ToniiqToniiq Ultra High Strength Glutathione Capsules - 1000mg Concentrated Formula - 98%+ Highly Purified and Bioavailable - Non-GMO Fermentation - 240 Capsules Reduced Glutathione Supplement
Main highlights- The Highly Purified Form of Glutathione - Toniiq Glutathione brings highly potent levels of liver support on the market. Our glutathione 1000mg contains an unprecedented purity level of 98%+ (most glutathione 500mg and liposomal glutathione products won't disclose their purity levels). Higher purity means more of the active compound in each serving that give glutathione its powerful properties.
- Quality, First, and Foremost - Toniiq products are produced in a GMP-certified, state-of-the-art manufacturing facility right here in the USA.
- Non-GMO Fermentation - Our glutathione is derived via a fermentation process to ensure a highly stable formula. Purity is attained using an advanced distillation process that involves fermentation, centrifugation, cell extraction, filtration, and crystallization. With its high levels of purity, our Glutathione also has high levels of bioavailability.
- Highly Purified and Bioavailable - Glutathione has amazing health benefits, but purity and absorption have always been a major challenge; something most other glutathione supplements don’t provide as it requires an extra step (and expense) in the manufacturing process. At a 98%+ purity level, Toniiq Glutathione provides some of the purest, most potent glutathione available.
- Each Batch is Individually Tested - We test each batch both ourselves and through a third-party independent laboratory to ensure your Toniiq product contains the correct standardized level of purity and active ingredients. We also test each batch for any possible additives, contaminants, and impurities to ensure the highest level of quality.
