Product Description

L-Glutamine
GI Support

The gut isn’t just the stomach. The gut is the entire digestive tract (from the mouth to the rectum) and is a complex mix of organs, microbes, hormones, and enzymes. How this complex mix of organs interacts dictates how well you will absorb the foods you eat. So what happens or doesn’t happen in your gut will inevitably impact your daily lifestyle. Because the digestive tract delivers the nutrients we eat to our bodies, there are many steps we can take to make sure we reap the full reward from these nutrients in terms of absorption, especially if someone is prone to gas, bloating, acid reflux, constipation, or other distress after eating. Optimal functioning of the gastrointestinal tract is vital to nutrient absorption, nutrient synthesis, the production of short-chain fatty acids for colon health, the elimination of waste, and proper immune function. An unhealthy diet, insufficient digestive enzymes, and taking various prescriptions can cause imbalances in the gut flora. That’s why supplementation is important, and it's is why Thorne offers well-researched, high-quality supplements that support a healthy gut.

Innovative Solutions

When the highest standards have been met, Thorne creates higher ones.

Sourcing Exceptional Ingredients

We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health.

Manufacturing the Right Way

We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified.

Four Rounds of Testing

We run four rounds of testing for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing, while most competitors test only one or two times. We test our raw materials, in-process batches, finish products, and product stability for each product.

Thinking Sustainably

We're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards.


Focus on sustainability

Compact by design from Climate pledge friendly. Certified by Amazon.

Small changes in product size & weight lead to lower carbon emissions.

We created Compact by Design to identify products that, while they may not always look very different, have a more efficient design. With the removal of excess air and water, products require less packaging and become more efficient to ship. At scale, these small differences in product size and weight lead to significant carbon emission reductions.

Here are a few of the many ways products can qualify:

Less packaging

Less air in container

More efficient shape

Waterless technology

Reviewed in the United States on May 8, 2022
I rented a house that had high levels of toxic mold/mycotoxins for 8 months and finally realized the reason for my numerous illnesses and debilitating sickness was from mold. I have CIRS and the mold took the worst toll possible on my gut. I developed food allergies to so many foods. I couldn’t eat anything without getting bloated, extremely tired, and out of breath. I was also always constipated and the only way I’d have a bowel movement was when I’d take my Adderall which I had to get in because the mold, but that caused me to have HORRIBLE IBS because my gut was so messed up! Detox is brutal and without a healthy gut, it’s impossible. I tried everything and spent HUNDREDS of dollars trying to heal my gut. Finally I read about this and figured I’d give it a try. I took it at like 2am one night on an empty stomach and I immediately felt gas leave my body and bloating go down. I for some reason only needed 3 hours of sleep that night instead of being able to sleep all day! When I woke up after a few hours, I felt SOO much better. INSTANT RELIEF! All the bloating was gone and I had almost completely normal bowel movements and better energy. After taking one the second night, I had healthy bowel movements, normal sleep FINALLY, no bloating, much less fatigue, etc. it truly was the only thing to be able to help me and I’m so grateful I’ve tried this. The only downside is it inhibits the absorption of my adderall a lot, but this has helped so much that soon I won’t need it anymore anyways. Thank you thank you thank you

Reviewed in the United States on October 11, 2019
My 13 year old daughter had a great amount of belly issues last year. When someone has stomach concerns, you rule out excessive worries, changes, diet, physical problems. We tried medication that suppressed stomach acids, meds to prevent the acid, anti anxiety meds. She was so bad at the beginning of the school year, vomiting was a daily occurrence. After an ER visit, multiple appts with the gastrologist, and endo scope and ZERO results, we tried many natural remedies that included going gluten free, probiotics and a variety of supplements. We tried other natural supplements. And tried to rule out conditions or symptoms by trial and error. This product has GIVEN MY DAUGHTER HER LIFE BACK!!! She was declining all social opportunities last year, scouting trips and sleep overs. It was debilitating to have belly pain after eating and eating from a very limited diet. THANK yoy so much for these pills. My daughter cautiously noticed a change right away. That was over 6 months ago. She takes the pill at night. NO ISsues or debilitating stomach problems. Stomach issues are super tricky to diagnose. We feel now that this supplement has helped what may be a leaky gut that was not found through a surgical procedure. Please, if you are having weird stomach issues and are looking for a remedy, try this product. My big girl has her life back!!!! Thank you thank you thank you!!!!!

My MD actually prescribed L-glutamine supplements for leaky gut, IBS and autoimmune-related problems. Following the doctor's recommendation, I started slowly with this product and experienced GREAT improvements in my digestive symptoms within one week.

Feeling confident, I slowly increased the dosage, and within the following week and a half, suddenly noticed strong, unrelenting heart palpitations and unexplained anxiety -- which I hadn't had in a long time. This particular supplement was the only new item I had added to my routine.

Other reviewers here have noted heart palpitations and arrhythmia issues after starting this, so I felt I should join the conversation and share my experience. I do think my bad side effects are dosage related. It's clear that I exceeded a safe dosage for me. If you research L-glutamine, you will find it can be harmful for some people using larger doses because it increases "excitatory" brain chemicals that trigger anxiety, heart rate, and so on. Start small. Be careful.

Not saying this doesn't work for digestive problems. It does work and it's a good quality product. But watch the dosage you start with -- and monitor how you feel after using consistently for more than a week. It took a week of use for the heart rate issue to show up. After I stopped the supplement, I returned to normal after 24 hours, no more heart palpitations.
