The Secret Service For Your Intestinal Wall

Watch this 2-minute video to see how Gut L-Glutamine nourishes your intestinal lining and protects your gut.

How It Works †

L-Glutamine is the most abundant amino acid in the body. So why use a supplement? Well, it turns out your intestinal cells gobble up roughly 1/3 of your body’s natural supply of glutamine. And if you have a leaky gut, you might require even more of this critical amino acid to repair bodily tissue, including your intestinal tract lining. You also likely need supplemental glutamine if you eat a vegetarian diet, because the foods with the highest amount of glutamine are animal-based. (Gut L-Glutamine is made by fermentation, so it is suitable for all diet types, including vegan/vegetarian.)
L-Glutamine is like a handyman for your gut wall. It makes things tighter and stronger. If you want the geeky explanation...L-Glutamine helps to tighten the junctions in between the endothelial cells in your mucosal barrier. The craziest part of all, is your gut wall is just a thin single-cell layer and runs over 15 feet long. It's like a fence made out of paper!
And if there are any large holes along this wall, then bad bacteria, undigested food and other metabolic waste may be able to enter the bloodstream. Hello leaky gut! Considering how fragile this barrier is and how stress depletes glutamine, it’s no wonder so many people have leaky gut symptoms. Thankfully, extra L-Glutamine can help.

How It Helps †

The Secret Service for your gut - L-Glutamine helps build a smart & strong gut wall that decides what goes through and what stays out. It's like having your own Secret Service team lining every inch of your 16 foot-long intestinal wall.
A healthy food buffet for your colon - not only is L-Glutamine the preferred fuel source for your small intestinal cells, but it’s also the best amino acid for your colon or large intestinal cells (we call them colonocytes). And this is important, because the colon is where the majority of your good & bad bacteria are found, a.k.a. the microbiome. Now, if you really want to geek out with us...research shows that properly-fed colonocytes help maintain balance in the lower digestive tract and transform dietary fiber into fermented, short-chain fatty acids. Both of which greatly contribute to overall gut health.
Does the work probiotics & enzymes can't - Why not just take a probiotic or digestive enzyme to overcome leaky gut symptoms like bloated belly, runny poop or a backed-up system? Think of it this way: taking them without L-glutamine, is like building a house without a solid front door. The living room may have the potential to be cozy, but without a barrier, the elements are going to creep in.
All-in-one gut, mood, brain & energy support - When your gut is strong and keeping out the inflammatory toxins, bad bacteria etc, the rest of your body can do what it does best.

Bailey Franzen RDN
Registered Dietician
As a registered dietitian, I'm experienced in helping clients meet their health goals with food and supplements. And the one thing I know is that if a product doesn’t taste good or is hard to mix, people stop using it. Which is why I’m so happy that Gut L-Glutamine comes as a very fine powder, that stirs easily in water and has a neutral flavor.
Richelle Godwin RDN
Registered Dietician
It uses the highest-grade L-Glutamine available and it is manufactured in a world class, NSF-certified facility right here in the USA.

Who It Is For
What does L-Glutamine actually do?
L-Glutamine is the most abundant amino acid in the body and the most important for maintaining the strength and integrity of bodily tissue, including the lining of the intestinal tract. In other words, L-Glutamine is the best fuel source for the cells that form the intestinal lining. Think about it this way...while Popeye ate spinach to grow his muscles, your intestinal wall likes to eat L-Glutamine! †
How does L-Glutamine help?
Studies show that supplemental L-Glutamine is mostly absorbed and metabolized in the tissues of the intestines. That’s great news if you have a leaky gut, which is caused by a weakening of the lining of the intestinal wall. Gut L-Glutamine supplies the extra glutamine needed to patch up and fortify the thin, single-layered mucosal barrier of the intestines. By strengthening and tightening up the junctions of the cells that line this barrier, L-glutamine prevents food particles, harmful bacteria and toxins from escaping into the bloodstream. When food particles and bacteria are kept in the intestinal tract where they belong, the body is more likely to maintain normal levels of inflammation, which supports all aspects of your overall wellness. †
How do I know if I should take this supplement?
Gut L-Glutamine may help if you experience any of the following symptoms: gas, occasional bloating, flatulence, GI discomfort, constipation or diarrhea. †
When should I take Gut L-Glutamine?
We recommend taking it first thing in the morning, with or without food. However, for best results, if we had to choose between with or without food, we’d pick without food. That’s because theoretically, you don’t want any other amino acids from the food you eat competing for your intestinal lining’s attention. And if you want to give even more support to your gut lining? You may also take a second scoop before dinner.
How should I take it?
Mix one scoop of Gut L-Glutamine powder (scoop provided) with 8 fl oz (240 ml) of water, or your favorite beverage. Do not mix Gut L-Glutamine with hot tea or any other hot beverages, as the heat may denature the amino acids. Also, if possible, avoid taking Gut L-Glutamine with any drinks that contain protein such as protein powder and milk. That’s because theoretically, you don’t want any other amino acids from the food you eat competing for your intestinal lining’s attention. Gut L-Glutamine is neutral-tasting and odor-free, and it mixes easily, so it’s a quick and easy digestive health supplement for your busy morning routine.
How much should I take?
Start with 1 scoop in the morning. Each scoop provides 5 grams of L-Glutamine. If you want a second scoop, take it before dinner.
How many servings / days supply?
Each tub contains 60 servings. A serving size is 5 grams (1 scoop). If you take just one scoop per day, one tub of Gut L-Glutamine will last your 2 months. And of course, if you go for two scoops per day, then it will last 1 month.
How should I store this?
Gut L-Glutamine does not need to be refrigerated. Store it in a cool, dry place.
How long till I feel a noticeable difference?
Because everybody is unique, it’s impossible to say with absolute certainty how long it will take to experience a positive outcome. However, being water-soluble, L-Glutamine gets absorbed in your body rather quickly. You may notice a difference within just days or weeks.
Does it contain gluten, dairy or soy?
No. Plus, it is 3rd party verified gluten, dairy and soy free.
Can I take Gut L-Glutamine with other Essential Stacks products?
L-Glutamine is safe to take in conjunction with all our other digestive health supplements.
Can children take Gut L-Glutamine?
We like to err on the safe side when it comes to children. So please consult with your child’s healthcare provider to determine if L-Glutamine is okay for them and what the appropriate dose would be.
Can pregnant or nursing mothers take Gut L-Glutamine?
Since research involving expecting- and breastfeeding mothers taking L-Glutamine is lacking, we recommend you consult your physician before using this or any dietary supplement. Also worth noting, L-Glutamine has been assigned to pregnancy “category C” by the FDA, which means that it is not known what impact it might have on an unborn baby or whether it passes into breast milk.
Are any medical issues contraindicated?
If you have any medical issues, please consult your physician before using this or any dietary supplement. In particular, those with kidney disease, liver disease or Reye's syndrome (marked by serious swelling in the liver and brain) should avoid taking L-Glutamine supplements.
Can I take it with my medications?
If you are taking any medications, please consult your physician before using this or any dietary supplement. In particular, L-Glutamine may reduce the effectiveness of certain anti-epileptic medications used to treat seizures.
