Glutamine is the most abundant amino acid (the building block units of protein) in the body and is involved in more metabolic processes than any other amino acid. Glutamine is especially important in serving as a source of fuel for cells lining the intestines and for the proper functioning of white blood cells. It is important to these cells because glutamine is utilized at higher rates by these cells and other rapidly dividing cells. Without glutamine, these cells do not divide properly.

The importance of glutamine is well-appreciated in conventional medicine. It is an extremely important component of intravenous feeding mixes in hospitals because double-blind studies have shown to dramatically increase survival in critically ill subjects.

Glutamine Protects and Heals the Gut

Glutamine is indicated in conditions linked to increased intestinal permeability (a “leaky gut”) including inflammatory bowel disease, celiac disease, diabetes, high sugar intake, and use of various drugs (in particular nonsteroidal anti-inflammatory drugs and prednisone). Glutamine is helpful in fighting the leaking gut by increasing energy production within the intestinal lining as well as by strengthening the tight junctions between cells.

Glutamine supplementation is a very important consideration in preventing some of the intestinal damage caused by chemotherapy and radiation. It has also been shown to prevent the mouth ulcers (stomatitis) and suppression of the immune system in cancer patients receiving chemotherapy

Glutamine supplementation has also been shown to be of value in patients undergoing abdominal surgeries such as gastrectomies, sigmoidectomies, cholecystectomy, colectomies, and rectal resections. Trauma from abdominal surgery may also compromise the intestinal lining and lead to a leaky gut. Glutamine supplementation has been shown to help reduce markers of intestinal permeability after abdominal surgeries.

Glutamine is also helpful in healing peptic ulcers. In a double-blind clinical study of 57 patients, those taking 1.6 g/day of glutamine showed better results than those patients using conventional therapy alone. Half of the glutamine patients showed complete healing within 2 weeks and more than 90 percent showed complete relief and healing within 4 weeks. It is believed that glutamine promotes the manufacture of protective mucoproteins that line the stomach and small intestine.

Glutamine Enhances Muscle Growth and Athletic Performance

Glutamine is the most abundant amino acid in the blood and in the free amino acid pool of skeletal muscle. Glutamine stimulates the synthesis and inhibits the degradation of proteins and is an energy source for muscle cell division. Glutamine is also a precursor for the synthesis of amino acids, proteins, nucleotides, glutathione, and other biologically important molecules. Glutamine has an anabolic effect on skeletal muscle.

There is some evidence that over-training results in low glutamine levels and that glutamine supplementation can help prevent over-training in the first place as well as help an athlete recover from over-training. Plasma glutamine concentrations increase during exercise. However, during the post-exercise recovery period, plasma concentrations decrease significantly. Several hours of recovery are required before plasma levels are restored to pre-exercise levels. If recovery between exercise bouts is inadequate, the acute effects of exercise on plasma glutamine concentrations can be cumulative leading to very low levels of glutamine.  This situation can have extremely detrimental effects on athletic performance and muscle growth. Glutamine supplementation has been shown to boost muscle levels of glutamine and promote muscle protein synthesis. However, it does not appear to enhance exercise performance in the absence of glutamine shortages in the body. The clearest benefit of glutamine supplementation in athletes is in the prevention of infections.

Glutamine Supplementation Improves Immune Function

Glutamine supplementation has been shown to boost immune function and fight infection. These effects have been best demonstrated in endurance athletes (extreme exercise suppresses the immune system) and critically ill subjects. It is not known if glutamine supplementation enhances immune function in healthy individuals.

Glutamine – Usual Dosage

Glutamine is available in capsules, tablets, and powder. The typical dosage of glutamine is 3 to 5 grams daily. An alternate recommendation is 20 to 30 grams of whey protein concentrate.

Glutamine – Side Effects

No side effects have been reported at dosages as high as 21 grams per day.

Glutamine – Drug Interactions

No adverse drug interactions are known. Glutamine may reduce some of the side effects of drugs on the gastrointestinal tract.

Dr Murray Profile Picture

This article was written by Dr. Michael Murray, one of the world’s leading authorities on natural medicine. For the past thirty-five years, Dr. Murray has been compiling a massive database of original scientific studies from medical literature. He has personally collected over 65,000 articles from the scientific literature, which provide strong evidence on the effectiveness of diet, vitamins, minerals, herbs and other natural measures in the maintenance of health and the treatment of disease. It is from this constantly expanding database that Dr. Murray provides the answers on health and healing on

L-Glutamine is an amino acid found in the skeletal muscles of the body. The amino acid is responsible for protein synthesis within the muscle cells. It is also needed for the proper function of the immune system. Taking dietary supplements of L-glutamine and eating a diet rich in lean proteins could help you to boost your workout.

One of the leading ways in which your body benefits from L-glutamine supplements is by enhancing athletic performance during high-intensity workouts. If you are already an active person who has a regular fitness routine, kicking up the intensity of your workouts could cause you to be fatigued.

Supplementing with L-glutamine can help your body to repair minor muscle damage from intense workouts. It may also help you to digest your food better so that your body can be supplied with a regular source of energy during workouts of a long duration.

Some people also find that using L-glutamine helps to increase their muscle mass, which could be an effect of the repairs and protein synthesis performed by the amino acid.

You know the importance of what you eat and how it impacts the rest of your body. But what you might not realize is how your food is digested in your body. The process is important, as your digestive system isn’t only responsible for breaking down food, but also absorbing important nutrients in the body. This is the part that’s often overlooked, and what research is showing to be the catalyst for many digestive diseases, such as leaky gut, acid reflux, irritable bowel syndrome (IBS) and Crohn’s disease. 

What Are Digestive Enzymes?

Digestive enzymes—some of which are produced naturally in our body from the pancreas—help us break down the food we eat into smaller, absorbable particles. But there’s another way to score key enzymes—through the foods and plants we eat—and these enzymes play a different function. They help us absorb vital nutrients that we need to stay healthy. When you consume a few nutritious foods, such as vegetables, fruit, and herbs, and chow down on too many processed foods, you don’t obtain the digestive enzymes you need. This is problematic, because, without these enzymes, the body spends too much energy digesting what you eat, leaving you exhausted, depleted and, worst of all, inflamed inside. This inflammation plays a role in many chronic illnesses, such as diabetes, hypertension and high cholesterol. 

What Is Leaky Gut Syndrome? 

A lack of digestive enzymes can cause leaky gut syndrome—another unfortunate result of chronic inflammation in the digestive system. There are many culprits that cause leaky gut, including stress, medications, poor food choices or quality, alcohol, cigarettes, and even hormone changes. What does the term “leaky” really mean, you might be wondering? Essentially, a healthy gut absorbs nutrients, but an unhealthy gut “leaks” nutrients, which in turn triggers an inflammatory response in the body. 

6 Steps to Healing Your Gut

  1. My general recommendations for treating leaky gut—and boosting gut health in general—begins with food. I often suggest patients first remove gluten and dairy from their diet, as these proteins can be tough for your body to break down, worsening an already-inflamed digestive lining. Another tip is to cut back on alcohol and sweets, as these also upset your gut. Stick to no more than four drinks each week and keep your refined sugar intake to no higher than 40 grams each day. 
  2. Adding in foods that naturally contain digestive enzymes is a great strategy for improving digestive health and leaky gut. Avocados contain lipase, an enzyme that helps with digestion of fat, while pineapple and papaya are rich in amylase, which breaks down starch. Bananas and kiwi also contain digestive enzymes and ginger acts as a digestive aid as well.
  3. Certain supplements can assist in healing leaky gut, including probiotics, live bacteria, and yeast. I recommend taking a high-quality probiotic supplement to help balance the microbiome (the environment in which these bacteria thrive) and improve digestion and your body’s absorption of nutrients. I suggest looking for a high colony count (above 20 billion CFUs). 
  4. For a probiotic-rich beverage, sip on kombucha! It’s one of my family’s favorite drinks—even the kids love it. You can buy kombucha pre-made or make your own at home. Nondairy kefir, bone broth, and fermented vegetables are additional food-based sources of probiotics.
  5. L-glutamine is an amino acid that has shown benefits in healing leaky gut or malabsorption. Adding 1-2 grams of glutamine into your favorite morning smoothie is another trick to improving digestive health.
  6. Lastly, supplementing with digestive enzymes can improve the critical issue of absorption of nutrients from food. Choose an enzyme that has amylase, lipase, and protease. Some digestive enzymes also contain hydrochloric acid or HCL, to further help with digestion of food.

The state of your gut is key to your entire health picture! From digestion to immune function, energy levels and hormone balance—if you take the time to repair, balance and nourish your gut, you have the potential to see an impact on your whole body.

She is the author of the best-selling books “Super Woman RX” and “The 21-Day Belly Fix.” Personal health challenges in her twenties combined with a broken healthcare system motivated Dr. Taz to pursue an alternative definition of health and healthy living. As a young resident, she was sick and without answers, and began searching for help to heal her health issues. Studying various systems of medicine including Chinese Medicine, Acupuncture and Ayurveda, she found a wealth of information not yet taught in conventional medical schools. It led her to opening her now nationally-recognized practice, CentreSpring MD. Today, Dr. Taz and her team work relentlessly to find a patient’s core health problems, their center, in order to spring them forth in health, pulling from multiple systems of medicine, including integrative, functional, Chinese and holistic medicine.
