Let's Talk About L-glutamine; It could be a game-changer for your DV!

Updated: Mar 18, 2023




If you haven't heard of L-glutamine, you might be missing an opportunity to reduce DV flare-ups! In this post, we will review what L-glutamine is, its benefits, and possible side effects; we will also provide links to additional sites for additional information and studies. As always, we are not doctors at Viva Gastro. We are providing pertinent information and experience so you can have productive visits/conversations with your doctor.


What is L-glutamine?


L-glutamine is an amino acid that is commonly found in the human body and plays an important role in many physiological processes, including the maintenance of gut health.

Some studies have suggested that supplementing with L-glutamine may help to reduce inflammation and improve symptoms in people with diverticulitis.

One of the critical benefits of L-glutamine is its ability to support the health of the gut lining, which can help to reduce inflammation and improve gut function. In addition, L-glutamine has been shown to improve the barrier function of the gut, which can help to prevent the leakage of harmful bacteria and toxins into the bloodstream.


L-glutamine is a beneficial nutrient for the intestines for several reasons:

  1. Maintains the integrity of the intestinal lining: L-glutamine is the primary energy source for the cells that line the intestines (enterocytes). This helps to maintain the integrity of the intestinal lining, which is crucial for preventing harmful substances from leaking into the bloodstream.

  2. Supports gut health: L-glutamine has been shown to help maintain a healthy balance of gut bacteria, support the growth of beneficial gut bacteria, and reduce inflammation in the gut. This can help to improve overall gut health and reduce the risk of various digestive problems.

  3. Reduces inflammation: L-glutamine has anti-inflammatory properties and has been shown to reduce inflammation in the gut. This is particularly important for people with inflammatory bowel diseases (IBD) such as Crohn's disease, Diverticulosis and ulcerative colitis.

  4. Improves nutrient absorption: L-glutamine can help to improve nutrient absorption in the gut, which can be particularly beneficial for people with malabsorption syndromes or other gut-related health problems.

It also has these additional benefits:

  • Improves overall health of the digestive tract by regulating cell division of the intestinal lining

  • Assists the body in producing glutathione, which is a potent antioxidant

  • Helps the body maintain pH balance

  • Helps maintain muscle mass

  • It helps in cellular and systemic detoxification

  • Promotes healthy neurological function and improves memory and learning

It is worth noting that while L-glutamine can provide many benefits for gut health and Diverticulosis, it is important to speak with a healthcare provider before starting ANY new supplement regimen. Everyone's body is different, it is important to discuss if you have any underlying conditions that supplents could exacerbate.

***If you have any of the following conditions, it is recommend NOT to take supplements/eat foods with Glutamine without talking with your doctor first. There are situations where it is fine, but your doctor needs to make that decision based on your particular situation:***

  • Kidney or liver disease

  • Reye’s syndrome

  • Cancer


L-glutamine is many foods, meat, dairy, and plant-based protein sources such as beans, raw spinach, parsley and red cabbage. We have a list of the top foods below.

I highly recommend adding the following to your diet; they are foods that have the most L-glutamine benefits.

  • Asparagus

  • Cottage cheese

  • Ricotta Cheese

  • Broccoli rabe

  • Fish, cod and salmon are highly recommended. Saltwater fish has more glutamine than freshwater

  • Seafood in general

  • Bone broth

  • Chicken/Beef/Lamb/Turkey/Venison/Pork

  • Spirulina

  • Chinese cabbage

  • Red Cabbage - Raw is best but could be a trigger for flare-ups; for some people

  • Milk, grass-fed is better/has more glutamine

  • Eggs

  • Yogurt

  • Nuts

  • Beans - Soybeans and kidney have higher amounts of glutamine

  • Parsley

  • Dark Leafy Greens

  • Legumes - chicpeas, peas, lentils

  • Spinach

  • Tofu

I use the following supplement daily/every other day, especially when I feel discomfort/pain or a flare-up coming on. I have found that it reduces the pain and duration of my flare-up. I mix it in with bone or chicken broth. FYI, there are a lot of snake oil salesman/websites and blogs out there trying to sell very expensive L- Glutamine products. Always do your own research, I did a lot of research, and I went with the one below for the following reasons: They are located/headquartered in the USA, and this product is made in a GMP-compliant facility using the highest quality ingredients and simple/clean formulations. They do 3rd party testing on top of that.

Dosage Suggestions: Always check with your doctor before taking, but here are dosage recommendations for the above product. It is recommended to start with 2-5 grams twice a day. I do 3 g per day and have seen results. There is some conflicting info on dosage; best to check with your doctor before taking more than that.


Some say up to 10 grams twice a day is good for you. The FDA has approved L-Glutamine at levels of 30 grams a day/15 grams twice a day for both short bowel syndrome and sickle cell; the second link below to the Mayo Clinic has more details; the third link is to the FDA regarding approval, and for what.
