Choosing the Right Glutathione: A Buyer's Guide

Introduction to Glutathione

Meet Glutathione - your body's own superhero antioxidant! It's like the avenger of your cells, fighting off free radicals and keeping your body in tip-top shape. Glutathione is made up of three trusty sidekicks - cysteine, glycine, and glutamic acid. Together, they form a dynamic trio, ready to take on any villain that threatens your skin.

But here's the plot twist: as we age, Glutathione's powers start to dwindle. With less synthesis and more oxidative stress, it's like our hero's strength is fading away. So how do you replenish this power ingredient and unleash its full potential for your skin?

That’s why many turn to Glutathione supplements to level up their defenses and unlock all these amazing benefits. Ready to dive into the world of Glutathione supplements? Let's embark on this epic journey together!

Glutathione's Benefits and Uses

Glutathione offers many science-backed health benefits:

  • Antioxidant Benefits

Glutathione is the body's master antioxidant. It helps protect cells from oxidative stress and free radical damage. This may help reduce inflammation, improve immunity, and slow aging.

  • Detoxification

Glutathione binds to toxins in the liver and helps convert them to less harmful compounds that can be excreted from the body. This is a key role in liver health and preventing damage.

  • Skin Health

Glutathione helps regenerate vitamin C and E in the skin, supporting collagen production. This promotes smooth, youthful looking skin. Ever dreamt of having a shield against UV damage and aging? Well, Glutathione's got you covered! It's like a skincare superhero, hydrating your skin, improving elasticity, and keeping you looking youthful. With its powers to slow down cellular aging and thwart damage across your body, Glutathione is the ultimate fountain of youth.

  • Liver Health

The liver requires ample glutathione to function properly. Glutathione enables the liver to remove toxins and process nutrients. It may help treat or prevent liver disease.

But fear not! Glutathione still has plenty of heroic deeds up its sleeve:

  • Immune Support

Glutathione supports healthy immune function in several ways. It helps white blood cells produce cytokines to fight infection. It also supports lymphocyte activity for an adaptive immune response.

Types of Glutathione Supplements

When shopping for glutathione supplements, you'll find there are a few different forms available.

Reduced Glutathione

- Reduced glutathione is the most common and well-researched form of glutathione supplement.

- It consists of the glutathione molecule in its active, antioxidant state.

- Reduced glutathione is reasonably well-absorbed when taken orally, with higher doses generally leading to increased blood glutathione levels.

- Reduced glutathione supplements are widely available and affordable. They provide a simple, proven way to increase your glutathione levels.

Liposomal Glutathione

- Liposomal glutathione comes encased in phospholipid bilayers called liposomes. This theoretically protects the glutathione from breaking down in the gut so that more can be absorbed into the bloodstream.

- However, there is little evidence that liposomal glutathione has superior bioavailability compared to regular reduced glutathione. More research is needed in this area.

- Liposomal glutathione supplements tend to be significantly more expensive than standard reduced glutathione. They may not provide enough added benefit to justify the higher cost for most users.

Acetyl Glutathione

- Acetyl glutathione supplements have an acetyl group attached to the glutathione molecule.

- This acetylation is said to help glutathione better penetrate cell membranes and raise intracellular glutathione levels. However, human studies are currently lacking.

- Acetyl glutathione supplements are not as widely available as regular reduced glutathione. The long-term effects and optimal dosing are unknown.

- For most people, regular reduced glutathione likely provides the best value and safety profile. But acetyl glutathione is an interesting new option for those looking to experiment.

So in summary, regular reduced glutathione supplements are the most proven and cost-effective option right now. Liposomal and acetyl glutathione offer potential advantages but may not provide enough extra benefit for their higher price tags. More research is still needed on these newer forms of glutathione supplements.

Factors To Consider When Choosing a Glutathione Supplement

When selecting a glutathione supplement, there are several key factors to take into account:


Bioavailability refers to how well your body can absorb and utilize the glutathione. Make sure that the format you choose protects the glutathione from being broken down in the digestive tract, resulting in significantly higher absorption and bioavailability. Poor bioavailability would mean the glutathione gets degraded in your stomach, so make sure you opt for enteric coated capsules which delay release until the small intestines. Sublingual tablets that dissolve under the tongue also help avoid degradation.


Glutathione dosage can range widely from 250mg to 1000mg per day. Lower doses are safer and more appropriate for general wellness. Frequency also varies - some take glutathione daily, while cycling on and off may help sensitivity. Follow dosage instructions on the specific supplement.

Additional Ingredients

Some glutathione supplements add complementary antioxidants like vitamin C, alpha lipoic acid (ALA), milk thistle, N-acetyl-cysteine (NAC), and selenium. These can help boost glutathione levels and activity. Avoid supplements with unnecessary fillers, preservatives, colors, and additives. Revered for their antioxidant prowess, Glutathione supplements like Setu’s Skin: Renew contain Vitamin C to neutralize free radicals and reinforce cellular defenses, supporting the body in its battle against oxidative stress.


When taking a glutathione supplement, it's important to follow the proper dosage guidelines to get the full benefits. Here are some key things to know about glutathione dosage and usage:

Typical Dosages

- The typical dosage for glutathione supplements ranges from 250mg to 1000mg per day. Lower doses around 250mg are common for maintenance or preventing deficiency. Higher doses around 500-1000mg are used for skin health, anti-aging, and other therapeutic benefits.


- Most oral glutathione supplements are taken once or twice per day. Dividing the daily dosage into smaller doses improves absorption.

- IV glutathione is administered in sessions ranging from weekly to a few times per month. This provides a high dose less frequently.

When to Consume

Oral glutathione is best taken on an empty stomach which aids absorption. It's often recommended to take it first thing in the morning or in between meals.

Length of Use

- Glutathione supplements can be taken for short or long periods, depending on your individual requirements. You can take it short-term, such as for 2-4 weeks. For ongoing benefits, you can also consume it long-term for months.

- It's generally considered safe to take glutathione supplements long term due to it being an antioxidant your body produces naturally. However, it's a good idea to cycle off every 6 months.


When it comes to choosing a glutathione supplement, several factors should be taken into account. Glutathione is an antioxidant with numerous benefits, such as immune support, detoxification, and skin health. When selecting a brand, it's essential to opt for those using patented ingredients and maintaining high manufacturing standards. Dosage recommendations typically range from 250 to 500 mg per day, ideally taken on an empty stomach for optimal absorption. However, it's crucial not to exceed the recommended dosage to prevent potential side effects.

To enhance glutathione absorption, consider taking it alongside vitamin C, NAC, alpha lipoic acid, or milk thistle. When comparing products, pay attention to the type of glutathione, dosage, additional ingredients, and price per serving. By following these tips, you can confidently select a glutathione supplement that meets your specific needs and goals, ensuring effectiveness without compromising quality.
