Have you been thinking about taking an oral glutathione supplement, but with so many alternatives available on the USA market, you are unsure which one is best? To assist you in selecting the best glutathione supplement, we have listed the top 3 brands available in the USA market.

But before that we need to understand some basic fundamentals of choosing the best glutathione supplement.

What To Look For In The Best Glutathione Supplement?

Unfortunately, getting enough glutathione from your diet alone is difficult due to stress, bad diet, or disease — so you'll need to supplement it if you want greater health.

The most effective way to increase your glutathione levels is to take a supplement containing all three of its building blocks: cysteine, glutamine, and glycine.

Finding the best glutathione supplement can be tricky, as there are many factors to consider. Here are some key things to look for:

Form of Glutathione:

  • Reduced L-glutathione: This is the most effective form of glutathione, as it is readily absorbed by the body.
  • Liposomal glutathione: This form is encased in fat-like spheres, which can help to improve absorption through the intestinal wall.
  • Acetyl-L-glutathione: This form may be better absorbed than regular L-glutathione, but there is less research on its effectiveness.


  • Choose a reputable brand: Look for brands that have a good track record and that manufacture their products in GMP-certified facilities.
  • Third-party testing: Make sure the supplement has been tested for purity and potency by a third-party lab.
  • Limited ingredients: Avoid supplements with a lot of fillers, additives, or artificial ingredients.


  • The recommended dosage of glutathione varies depending on the individual and the condition being treated. However, most supplements range from 250mg to 1000mg per day.
  • It is important to start with a low dose and increase gradually as needed.

Look for glutathione supplements like Infinite Labs, which have a very clean and pure formula of Liposomal Glutathione. Infinite Labs’ Liposomal Glutathione+ contains no GMOs, no sugar, no gluten, no soy, and no artificial flavors or sweeteners.
