L-Glutamine Deficiency
While the body can produce L-Glutamine, certain factors can lead to a deficiency, including:
- Intense exercise or physical stress
- Injury or surgery
- Chronic illness
- Poor diet or malnutrition
Symptoms of L-Glutamine deficiency may include:
- Muscle wasting

L-Glutamine Dosage and Administration
The recommended daily dosage of L-Glutamine varies depending on individual needs and health status. Generally, a dosage of 5-15 grams per day, divided into smaller doses, is considered safe and effective. Factors such as age, body weight, and health conditions may influence the optimal dosage.
L-Glutamine supplements are available in various forms, including:
- Powder
- Capsules
- Tablets
For optimal absorption, L-glutamine should be taken on an empty stomach, either 30 minutes before or 2 hours after a meal.
Potential Side Effects and Precautions
While L-Glutamine is generally considered safe, some individuals may experience side effects, such as:
- Digestive discomfort (bloating, diarrhea, or constipation)
- Headache
- Nausea
- Skin rash
Pregnant and breastfeeding women should consult with their healthcare provider before taking L-Glutamine supplements. Individuals with certain health conditions, such as liver or kidney disease, should also seek medical advice before supplementing with L-Glutamine.
L-Glutamine may interact with certain medications, including:
- Anticonvulsants
- Chemotherapy drugs
- Lactulose
L-Glutamine and Mental Health
L-Glutamine plays a crucial role in brain function and mental health. As a precursor to the neurotransmitter glutamate, it helps regulate mood, cognitive function, and memory.
Studies have suggested that L-Glutamine supplementation may be beneficial for individuals struggling with depression, anxiety, and addiction. By supporting neurotransmitter production and reducing oxidative stress in the brain, L-Glutamine may help improve overall mental well-being.

L-Glutamine and Gut Health
L-Glutamine is essential for maintaining a healthy gut lining, which is crucial for overall digestive health. By supporting the integrity of the intestinal barrier, L-Glutamine helps prevent leaky gut syndrome and reduces inflammation in the digestive tract.
Supplementing with L-Glutamine may be particularly beneficial for individuals with digestive disorders such as inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS). Studies have shown that L-Glutamine can help reduce intestinal permeability and alleviate symptoms associated with these conditions.
L-Glutamine and Athletic Performance
Athletes and fitness enthusiasts often use L-Glutamine supplements to support muscle recovery and growth. L-Glutamine can help minimize post-exercise muscle soreness and improve overall athletic performance by reducing muscle breakdown and promoting protein synthesis.
L-Glutamine may also help improve endurance by reducing fatigue and supporting energy production during prolonged exercise. Combining L-Glutamine with other performance-enhancing supplements, such as creatine and branched-chain amino acids (BCAAs), may benefit athletes and bodybuilders.

L-Glutamine for Gut Health and IBS
I can’t speak for any of the other benefits, but I’ll note #3: Digestive Health. In my research to improve my mom’s GI health (cholecystectomy, celiac disease, chronic diarrhea, poor nutrition uptake, etc.), L-Glutamine kept popping up with a fair amount of research supporting it and it being advised by GI specialists.

L-Glutamine for Sugar Cravings and Alcohol Addiction
I’ve been using glutamine for several years. Initially, I was using it to curb sugar cravings, but after a terrible experience with food poisoning I also value using it for gut healing/health.

Potential Side Effects and Precautions with L-Glutamine
I have tried glutamine and it was utter trash. It exacerbated my underlying mystery disease. Irritability, brain fog, fatigue, insomnia from what I can remember. You can argue whether it was due to glutamate, ammonia, (lack of) lipopolysaccharide, or something else. One thing is for sure, I will never touch that shit again. Strange though because I find protein and protein powders completely safe.
