Our immune systems are under constant stress from air pollution, allergens, and pathogens. That’s why many Americans are looking for ways to support their immune health and help protect themselves from these threats.
Thankfully, we can promote immune health by supplementing with glutathione. This powerful antioxidant can help protect the respiratory system, support cell detoxification, and promote a strong immune response.
So it’s no wonder why the market is being flooded with hundreds of glutathione supplements. However, not all of these supplements are made equal. Some have undesirable fillers or lack the right dosages.
That’s why Consumers Survey compiled years of research. In this guide, we discuss and reveal the Top 5 glutathione supplements on the market today.
How Do Glutathione Supplements Promote Immunity?
Glutathione is a very powerful antioxidant. Our bodies produce it naturally to help fight off threats like pathogens and pollution. However, we don’t always produce enough glutathione.
Studies Show Glutathione Helps:
- Promote Cell Detoxification
- Ease Coughing
- Support Mental Clarity
- Improve Energy Levels
Avoid Raw Glutathione
Some supplements contain glutathione itself. We recommend avoiding them because glutathione as an ingredient isn’t very absorbable. On the other hand, our bodies can readily convert an amino acid called L-cysteine into glutathione. That’s why we recommend glutathione supplements that contain L-cysteine.
On top of L-cysteine, a quality immunity formula includes complementary ingredients that support your body’s defenses.
Your Glutathione Supplement Should Contain:
L-Cysteine
Studies show that taking L-cysteine helps increase your glutathione production, which supports a strong immune system. For best results, we recommend supplements with at least 500mg of L-cysteine.
African Geranium
Also known as Pelargonium sidoides or umcka, this botanical has been widely thought to support immune cell function. In particular, umcka can help promote quicker recovery and resistance to unwanted particles.
Elderberry
Elderberry has been shown in many studies to help improve immune health and help the body recover faster. Elderberry helps glutathione deliver its best immunity benefits.
Zinc
This nutrient promotes a strong immune response, aids your body’s ability to fight off environmental threats, and plays a critical role in natural cell detoxification.
Vitamins C, D, & E
These vitamins help support natural tissue repair, maintain normal cell health, and boost immunity. When combined with glutathione, these vitamins provide powerful support for healthy cell detoxification.
What to avoid
Raw Glutathione
We can't absorb raw glutathione well, so taking it in supplement form leads to limited immunity benefits. That's why we recommend looking for immunity supplements that contain at least 500mg of L-cysteine, an amino acid our bodies easily convert into useable glutathione.
Weak Dosages
Since our bodies don’t always produce enough glutathione on their own, we recommend supplements with strong L-cysteine dosages. Look for a formula with at least 500mg of L-cysteine.
Undesirable Fillers
Cheap fillers like magnesium stearate and titanium dioxide are used to cut down on costs during the manufacturing process. However, they can become toxic to your system and have negative effects on your immune system in large doses.

2. L-Cysteine by NOW Foods
Great Immunity Supplement
NOW Foods’ Glutathione provides a strong 500mg dose of L-cysteine as well as a couple of supporting nutrients, including B and C vitamins.
However, this supplement lacks several complementary, immune-supporting ingredients, including elderberry, zinc, and umcka. As a result, it doesn't provide the best immune defense.
That said, its strong L-cysteine dosage and lack of soy, gluten, and GMOs makes it a strong supplement. It earns the number 2 spot on this list.
3. glutathione Force by Bulletproof
Good Immunity Supplement
Bulletproof’s Glutathione Force contains a respectable dose of raw glutathione and some supporting nutrients.
However, this supplement’s immunity support falls short. It contains raw glutathione instead of L-cysteine, so it can’t offer sufficient protection against pollutants and pathogens. It also lacks any ingredients that deal specifically with air pollution.
As far as raw glutathione supplements go, however, Bulletproof makes a strong one free with no undesirable fillers. We gave it the #2 spot on this list.

4. Glutathione By Thorne Research
Adequate Immunity Supplement
Thorne Research’s Glutathione provides 200mg of raw glutathione, as well as a number of supporting nutrients.
However, this supplement contains limited ingredients that help your body resist air pollution. Without this critical support, Thorne Research’s glutathione supplement doesn’t sufficiently protect your immune system or body from coughing, chest discomfort, or wheezing.
While its money-back guarantee only lasts for 60 days, it still beats out many other supplements. Thorne Research gets the number four spot.

5. Glutathione By Swanson
Average Immunity Supplement
Swanson’s Glutathione is very pure, containing nothing but a 200mg dose of the raw antioxidant.
However, this supplement’s immunity and respiratory support could both be stronger. Its glutathione dose is on the weaker side, and using the antioxidant’s raw form is thought to lead to lower absorbability.
While it only extends for 30 days, we do appreciate Swanson’s money-back guarantee. On top of that, we admire Swanson’s commitment to purity. It deserves a shout-out on this list.
