WHY GLUTATHIONE IS ALL OVER YOUR SOCIAL MEDIA FEEDS

It feels as though every day I discover a new magic ingredient on TikTok, one that promises to heal my gut or give my skin radiance sans makeup. But when I saw people touting glutathione as the Goldilocks of antioxidants, I knew it was worth trying.

Celebrities like Gwyneth Paltrow and Kim Kardashian praise glutathione for its gut, skin, and overall body benefits, and while there are a lot of trendy ingredients, even experts agree that glutathione is more than just a fad. “Glutathione is your body’s master antioxidant, and it earns that title,” says Coco Pierrel, a certified integrative nutritionist and founder of Eat Shed Glow. “What makes glutathione the master is that it not only defuses damage from free radicals, but it also recharges your other antioxidants, like vitamins C and E, so they keep working.”

The irony of glutathione is that our bodies naturally produce the antioxidant. Still, factors like stress, pollution, alcohol, and age can diminish glutathione levels, which ultimately help protect our cells from these factors. It’s like a catch-22, which is why taking ingestible forms of glutathione can help boost cell protection, even when our bodies’ production declines.

Sounds promising, but how exactly does glutathione work, and what’s the right way to add it to your routine? Ahead, experts dive into the master antioxidant, its benefits, and the best ingestible forms, from drops to gels to capsules, to stock up on.

What Is Glutathione?

Pierrel says to think of the master ingredient as the rechargeable battery for the rest of your antioxidants. “Glutathione is a tiny molecule your body makes in every cell, built from just three amino acids, and it quietly does three jobs at once: it calms the damage that ages you from the inside, it powers your liver’s natural detox, and it keeps your whole antioxidant defense running around the clock,” she says.

You may be familiar with antioxidants, but Rachel Brief, a registered dietitian and wellness advisor attheLanby, says that glutathione is not like the antioxidants in superfoods like blueberries or kale. It’s an antioxidant produced in the liver that supports immune function, protects against oxidative stress and free radicals, and repairs cells. However, it declines with age, so adding a supplement can help support the processes, even as production drops off.

Why Should You Take Glutathione?

Glutathione is the Goldilocks of antioxidants—anyone and everyone can benefit from a boost of the antioxidant. However, if you’re looking to improve your gut health, boost immunity, and brighten and protect skin, glutathione is a great addition to your routine.

Amy Davis, a registered dietitian based in New Orleans, says that women can especially benefit from glutathione supplements for several reasons, first and foremost for hormonal benefits. “Glutathione plays a large role in clearing estrogen metabolites from the body,” she explains.

If you’re going through perimenopause or menopause, glutathione can be especially beneficial. Pierrel echoes this, adding that estrogen has antioxidant properties of its own, but as estrogen levels drop during perimenopause and menopause, oxidative stress rises. Since natural glutathione production also decreases, there’s little defense against the increase in oxidative stress. This is where supplementing glutathione to bring production levels back up comes in handy. And there’s a reason why glutathione is known for giving a “glow-up”—the ingredient has been said to support skin elasticity and even skin tone.

Around the same time perimenopause typically begins, collagen production and natural antioxidant defenses also decline, so experts recommend starting glutathione in your 30s (the earlier, the better). Aside from supplements, Brief mentions ways to support your body’s natural production of glutathione, including adequate protein intake, regular exercise, quality sleep, and a nutrient-dense diet—all easier said than done, but implementing good habits can have a greater impact than taking supplements.

What Are the Benefits?

Since every part of our body (our brain, skin, gut, and other organs) is affected by oxidative stress, glutathione is beneficial overall. For beauty benefits, most glutathione users notice their pigmented, lackluster skin brightens and glows. The antioxidant also improves gut function (from a calmer gut to more regular bowel movements), boosts immunity, increases energy, and accelerates metabolism. Since glutathione can benefit every system in our bodies, not all the benefits are seen immediately; for example, it supports cellular protection that helps prevent chronic health conditions down the road and promotes healthy aging.

How Much Glutathione Should You Take?

With any supplement, experts recommend starting small and working your way up to a higher dose. “For general antioxidant and immune support, research says around 250 to 500 milligrams a day,” Pierrel says. “If your goal is skin tone and radiance, that range moves up toward 500 to 1,000 milligrams a day.” Anywhere between 250 milligrams and 1,000 milligrams is the sweet spot, according to most experts. Luckily, most supplements are pre-dosed, so it takes the guesswork out of tracking milligrams. More important than the dosage is consistency. “This is what moves the needle,” Pierrel adds. She also says combining glutathione with vitamin C is one of “the smartest moves you can make,” as the two ingredients amplify each other’s effects.

Another reason glutathione has been trending: IV iterations, which Pierrel says are not just a fad. “The appeal is real, because it skips digestion and acts fast, which is exactly why it has earned its place in the wellness world,” she says. “If you go that route, the smart move is to do it with a qualified provider, since dosing is not standardized and, while reactions are uncommon, it is a medical treatment, not a casual add-on.”

Are There Downsides to Taking Glutathione?

The benefits of glutathione certainly outweigh any downsides. However, if you have a sensitive gut, an overload of glutathione can cause a slight disruption to digestion, which is why experts suggest starting with a smaller dose and working your way up. As with any supplement, it’s best to consult a doctor to ensure the ingredient is safe for you to take.
