Our editors have researched and taken clean supplements for years. These are our picks for glutathione supplements with quality, third-party-tested ingredients.

Looking to up your wellness game this year? Many of the top wellness trends for 2026 have to do with supporting your health at a cellular level and focusing on longevity and healthy aging. Enter glutathione supplements. 

This compound is an essential and powerful antioxidant naturally produced in our livers. It protects cells from damage by neutralizing free radicals and supporting detoxification processes, and it’s often called the “master” antioxidant. Glutathione is also involved in the transport of amino acids across cell membranes.

And our bodies’ natural glutathione levels decline with age, stress, illness, and environmental toxin exposure. So if you’re in the market for a glutathione supplement, read on for our comprehensive guide.

What are the benefits of taking glutathione?

Because it can help reduce your body’s oxidative stress, glutathione can protect against chronic conditions such as diabetes, arthritis, and heart disease. It also aids with liver detoxification, which is especially important if you’re taking certain medications that cause your liver to work overtime (talk with your doctor before incorporating glutathione, of course). Glutathione works on a cellular level in each of your body’s cells, so it also aids with everything from immune health to skin health to cellular repair.

What should you look for in a glutathione supplement?

When shopping for glutathione supplements — and all supplements, really — we always look for the cleanest ingredients. That means buying from brands that prioritize third-party testing and don’t use any unnecessary fillers, dyes, or binders. We also love products that are made in the US and that come in more sustainable packaging.

Should you consider liposomal glutathione?

Liposomal glutathione is a popular form of glutathione you’ll find in several of the products below. Basically, in this form, the glutathione is protected in liposomes, which are fats, that shield the delicate glutathione from stomach acids so it better absorbs into your bloodstream during digestion. But not all brands use it—some use reduced glutathione, which is the compound’s active form and can be used by your body right away with no conversion.

Our criteria:

After researching, corresponding with brands, and combing through customer reviews, our editors have chosen the best clean and effective glutathione supplements to support cellular health and antioxidant defense. We update this list regularly with new, emerging favorites, and all of our picks are evaluated to meet the following criteria.

  • SCIENCE-BACKED | Glutathione supplements can be beneficial for many people (though not all, so be sure to consult your doc!). We’ve selected options that prioritize bioavailability (such as liposomal delivery or clinically studied forms), are easy to take, gentle on digestion, and supported by scientific research and practitioner use.
  • THIRD-PARTY TESTED | Each brand uses high-quality glutathione or glutathione-supporting compounds without synthetic fillers, artificial flavors, dyes, parabens, or unnecessary additives. The options on this list offer third-party testing or purity verification so you can feel confident in potency, absorption, and safety.
  • ETHICAL & SUSTAINABLE | These brands are transparent about sourcing, manufacturing practices, and ingredient integrity. They prioritize responsibly sourced raw materials, clean manufacturing standards, eco-conscious packaging, and ethical supply chains.

1. Thorne

American made
Cruelty free
Dairy free
Doctor approved
Gluten free
Science backed
Soy free
Subscriptions available
Vegan

Best For | Glutathione for athletes
Dose | 1 capsule taken twice or thrice daily
Prices starting at | $54; $1.80/serving

Like all Thorne supplements, their Glutathione-SR is rigorously third-party tested and designed with athletes in mind. While glutathione is our bodies’ most abundant antioxidant, it also depletes quickly once you’ve been exercising for over an hour—so endurance athletes might find it beneficial to supplement. Thorne’s product has a sustained release formula to provide more steady antioxidant support for helping the body respond to physical activity, taken in the form of one capsule two or three times daily. And, for athletes’ peace of mind, the supplement is NSF Certified for Sport, meaning it’s been tested to guarantee the absence of around 300 substances banned by major athletic organizations.

Customer Review | “I was recommended this from my nutritionist friend and it truly is a game changer. I didn’t realize how crucial it is for everyday living and ALSO basically killed my urge to drink alcohol. I was already cutting down but since taking Glutathione, the need/want isn’t really there anymore. If you want to improve your everyday life, this is a must have on your list!” – Dylan M.

2. Renue by Science

Third party tested
Vegan

Best For | A nighttime glutathione supplement
Dose | 1 capsule daily
Prices starting at | $52; $0.58/serving

Renue by Science’s Lipo Glutathione supplement is specifically formulated for absorption and bioavailability. Because the antioxidant is so susceptible to digestive enzymes, this capsule surrounds the glutathione in powder-based liposomes to protect it, helping the “Master Antioxidant” do what it does best: protecting cells from oxidative stress, helping detoxification pathways, and assisting cellular repair. This delivery method even helps sustain your blood levels of glutathione for a longer period of time. And because a serving size is only one capsule, this supplement is one of the most affordable on this list. The brand also makes a Restore PM supplement that combines glutathione with other ingredients like GABA, 5-HTP, apigenin, and melatonin. 

Customer Review | “This is easy to take and seems to be effective. Other liquid liposomals taste awful. It also had the desired effect on my liver indicators. Good product.” – Melanie Dubowski (Read more reviews.)

Each serving includes two capsules, and can be taken with it without food. Based in Boca Raton, Florida, the brand uses HDPE for all its packaging, one of the most commonly and easily recycled forms of plastic (so make sure you recycle after use!).

Customer Review | “I won’t beat around the bush, plan and simple, this stuff WORKS! Each morning I take a serving and head out for the day. My desire to work hard and actually have the energy to do so now is incredible. I’m focused, my body feels refreshed, and I actually feel like my old younger self.” – Justin B. (Read more reviews.)
