Trusted by 1000s for better gut health
What Makes Us Different
Most supplement companies cut corners where you can't see - using overseas manufacturing, skipping independent testing and loading products with gut-irritating fillers. We take the harder, more expensive path because your gut health deserves better than “industry-standard”.
Third-Party Tested In The USA
Most companies only test their products internally - we do both. Our formulas get tested in-house, then verified again by independent ISO-certified labs where scientists screen for contaminants and validate our allergen-free promises. Because we believe your gut health journey deserves nothing less than exceptional quality.

United StatesA good daily supplement for gut health
I started taking Gut L-Glutamine a couple of years ago after trying another supplement for gut health from Amazon. After doing some research on those ingredients, I switched to this product from Essential Stacks, also from Amazon. I decided to buy directly from Essential Stacks since I was moving away from Amazon purchases. It, along with taking an IBGard peppermint capsule, has given me relief from periodic pain in the lower left quadrant of the stomach which my doctor could not determine a cause. I continue to mix a measured amount in 8 oz glass of water each day for ongoing relief.
United StatesHelpa tremendously with rosacea
I take three times the recommended dose and find that, with the proper diet, this helps tremendously with my rosacea. Worth every penny.
United StatesLove this product!
This product is a total life saver. Totally fixes my digestive issues. I take it sporadically through the week. And if I get stressed I take it twice daily and I really feel the difference. I have recommended this product to so many people!
United StatesExcellent bloating relief
Whenever I run out of this product, I immediately order more. It really helps with my bloating, I just add it to my greens powder every morning!
United StatesThis product just works.
