Ultra High Strength Glutathione Capsules - 1000mg Concentrated Formula - 98%+ Highly Purified and Bioavailable - Non-GMO Fermentation - 120 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 compounds in each serving that give glutathione its powerful properties.

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.

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.

Quality, First, and Foremost - Toniiq products are produced in a GMP-certified, state-of-the-art manufacturing facility in the USA.

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.

Liposomal Glutathione 1500mg, Oral Glutathione Liquid, Glutathione Supplement with Vitamin C & Hyaluronic Acid, Superior Absorption, 60 ml

Main Highlights

Master Antioxidant: Glutathione has been termed “the master antioxidant” because of its ability to quench free radicals and protect cells from damage. When taken as part of your daily routine, glutathione may help protect skin and promote a more youthful appearance by reducing signs of aging.

High-Strength Formula: Each serving of our liposomal glutathione liquid delivers 1500mg of high-quality glutathione to your body. It is carefully formulated with L-Glutathione (reduced), Phosphatidylcholine, Vitamin C, Aloe Vera Oil, and Hyaluronic Acid to ensure superior absorption and maximum effect.

Advanced Liposomal Delivery: Glutathione (reduced) is a supplemental form of glutathione. The reduced form is stable and possesses antioxidant properties. However, glutathione is a large molecule and is poorly absorbed on its own. Liposomes are microscopic spheres made of phospholipids that envelop nutrients like glutathione to help your body absorb more glutathione.

Why Liposomal Glutathione: We take our liposomal glutathione supplements seriously. Made with the highest quality ingredients, our formula is gluten-free, soy-free, wheat-free, dairy-free, and contains no added sugar.

Liquid Glutathione: You can take it in various ways: place it directly in your mouth and swallow, or mix it with your favorite juice or water. For best results, take 2ml (approximately 30 drops) daily. No more hard-to-swallow pills or capsules! This product is intended for adults only.
