Dietary Supplement Liver/Detox Foundational Sustained Release NSF Certified Sport Gluten Free Thorne's Glutathione is NSF Certified for Sport®. It occurs naturally in cells and is a cofactor in dozens of enzymatic reactions involved in detoxification. As an antioxidant, glutathione directly quenches several reactive oxygen species (free radicals). The body's benefits from maintaining a normal level of glutathione include support for liver function, pulmonary function, immune function, bowel health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health. Glutathione-SR is a breakthrough in glutathione supplementation because its sustained-release formula protects it from stomach acid and digestive enzymes, allowing for a slower release and a more steady level in the bloodstream of this essential nutrient. Glutathione is the most abundant anti-oxidant. Since training and competition create more oxidative stress and damage, athletes have a higher need for antioxidants. Exercise longer than 60-90 minutes significantly decreases glutathione levels in the blood, so supplementing is beneficial for endurance and ultra endurance events. The liver is the body's largest reservoir for glutathione. A potent endogenous antioxidant, glutathione is essential for the liver's phase I and phase II detoxification. However, negative lifestyle issues and adverse conditions that affect liver health can result in a decreased amount of glutathione in the liver. Maintaining an optimal level of glutathione appears to be important for supporting cognitive function, especially during aging. The normal process of aging is associated with a decrease in glutathione activity, which can result in increased oxidative activity. Less than an optimum level of glutathione is observed in individuals experiencing a decline in cognitive function. Conversely, individuals who live to 100 tend to have higher glutathione activity. Although a common mistaken belief is that glutathione is not well absorbed when it's taken orally, significant data confirms that glutathione is efficiently absorbed across the intestinal epithelium by a specific uptake system. Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations.

Glutathione is an important anti-oxidant. This is a good sustained-release form of glutathione. Thorne is one of the best brands iherb carries. At the same time, as one would expect, their products are more expensive than average, Glutathione-SR being no expection, as the cost per capsule exceeds 0.5 euros.
Paying a bit more for quality goes a long way with this glutathione product from Thorne. I had visible improvement to complex and skin elasticity as well as an improvement in digestion and liver function in just a few weeks. I highly recommend and will buy again.
I’ve been using Thorne’s Glutathione-SR for a few months, and the difference in my skin is incredible. It looks brighter, clearer, and overall healthier. This supplement has helped reduce dullness and even improved the texture of my skin. I love that it’s a sustained-release formula, which ensures consistent support throughout the day. Highly recommend for anyone looking to enhance their skin health from within!
Thorne Glutathione-SR is an absolute game-changer for my daily wellness routine. I've tried other glutathione supplements, but the sustained-release formula from Thorne truly sets this one apart. It gives me confidence that I'm getting steady, all-day absorption of this critical "master antioxidant." Here's what I've experienced: • ⚡️ Increased Energy and Vitality: I noticed a boost in my overall energy levels within a few weeks. I feel more ready to tackle the day and have less of that mid-afternoon slump. • ✨ Skin Glow: A surprising, but welcome, benefit has been the visible improvement in my skin. It looks brighter, clearer, and has a healthy, natural "glow-up." • 💪 Better Recovery and Detox: As an active person, I appreciate the added support for detoxification and managing oxidative stress. I feel like my body is recovering faster, and my overall immune function seems stronger. • ✅ High-Quality and Trustworthy: Thorne is a brand I trust implicitly. Knowing it's NSF Certified for Sport and doesn't contain unnecessary fillers gives me peace of mind about what I'm putting into my body.
Thorne is a trustworthy company. I reached out to them with concerns about one of the ingredients, and they readily explained its purpose and why it was included. I truly appreciated their clear and professional response. If you ever have concerns, I encourage you to contact them directly through their website. They replied within 2–3 business days, so be patient—they go above and beyond. I’m taking this supplement for added immunity, and within just a few days I’ve noticed subtle improvements: better digestion, more regular bowel movements (no diarrhea at all), and improved sleep. This is exactly what I was hoping for, and I’m excited to see the effects after 3–4 weeks. My plan is to keep this in my daily routine for several months, and then move to a maintenance dose. I will continue transitioning more of my supplements to the Thorne brand, gradually. While their products are not the cheapest, my health is worth the investment—and I’m already experiencing the benefits. I carefully research every supplement and its ingredients before making a decision, and Thorne has never disappointed me. I pray it works just as well for you, too.
This sustained-release glutathione is exceptional for combating oxidative stress. I’ve tried many brands, but Thorne’s formula resists stomach acid breakdown, ensuring optimal absorption. Within a month, my skin looked brighter, and I recovered faster from workouts. It also supports liver detox, which is crucial as estrogen declines. The capsules are small and easy to swallow. Pricier than some options, but the quality justifies it.
Thorne, Glutathione-SR, 60 Capsules (175 mg per Capsule) Score: 8/10 Introduction & context: This supplement delivers reduced glutathione in a sustained-release format, claiming to support antioxidant defense, detoxification, and cellular health. Each capsule contains 175 mg, priced at a premium. Third-party tested by NSF. Evidence summary: Human trials are limited but promising. A small RCT (N=29) using 250 mg/day showed improvements in markers of oxidative stress after 4 weeks. However, doses above 200 mg lack robust clinical data. The sustained-release form may enhance absorption, but direct comparisons are scarce. Formulation & quality analysis: Utilizes Setria® glutathione, a well-regarded form. Sustained-release technology is supported by pharmacokinetic studies showing prolonged plasma levels. No major contaminants detected in NSF testing, but proprietary blend opacity remains a minor concern. Safety & interactions: Generally safe; mild gastrointestinal issues reported. Caution in individuals with glutathione-related disorders. Potential interactions with nitrosoureas and cisplatin. Personal experience: Noted subtle improvements in energy and skin clarity, but benefits were not definitive. Cost outweighed perceived effects. Value & practicality: At $0.86 per 175 mg dose, it’s pricey relative to evidence strength. Liposomal formulations might offer better bioavailability at a similar cost. Overall verdict: Strong evidence for antioxidant support, but high price and limited high-dose trials temper enthusiasm. Suitable for those prioritizing sustained glutathione delivery. Who it's for: Individuals with specific oxidative stress concerns or glutathione deficiency. I’d consider alternatives like liposomal glutathione for better value.
