L-Glutamine: Health Benefits, Dosage, Side Effects & Supplements

Glutamine is an important amino acid required to serve many critical roles in the body. This conditionally essential amino acid, being the most abundant, is found in the liver, skeletal muscles, plasma, lungs, intestines and brain.  

The body can produce glutamine. Its concentration and availability depend on the balance between its synthesis, release and uptake by organs and tissues in the whole body. Glutamine requirement increases in our body under conditions like intense physical activities, surgery, or infections. Under such cases, it becomes essential to supply glutamine externally to meet the demands. 

The low glutamine concentration affects the whole body because many metabolic pathways and mechanisms dependent on glutamine availability are affected, resulting in low immunity levels.

Glutamine exists in two forms: L-Glutamine present in food sources and dietary supplements and D-Glutamine, which is biologically unavailable. Eggs, meat, dairy products and tofu are some glutamine-rich foods. Glutamine supplements are available in powder and capsules form that is pretty popular among bodybuilders and fitness lovers.

As mentioned above, glutamine is involved in many bodily processes, and the next section will discuss why you should not underestimate glutamine. 

Why do we need glutamine?

Let us have a detailed overview of glutamine benefits and uses.

  1. Strengthen immune health: Studies indicate that glutamine is an essential modulator of our immune cells – macrophages and lymphocytes. During infections, the utilization of glutamine by the immune cells rises; hence the external supply of glutamine becomes imperative to maintain the total plasma glutamine concentration. Low levels may increase the risk of subsequent infections. In addition, glutamine has been shown to suppress the levels of certain inflammatory compounds. Therefore, make sure that you don’t have glutamine deficiency if you want your immune system to run strongly.
  2. Amplify athletic performance: If you are into intense workouts or any endurance sport, glutamine supplementation might benefit you. Athletes prefer taking glutamine because of its potential to boost the recovery process. This amino acid has been shown to ease muscle soreness and speed up recovery. A study published in the Journal of Human Sport and Exercise observed that glutamine supplementation improved male athletes’ exercise performance during an eight-week resistance training program. Another study published under the British Journal of Sports Medicine noticed that L-glutamine supplementation weakens DOMS effects when ingested for four weeks.  
  3. Promote muscle growth: Glutamine assists in the transportation of nitrogen in the body required for new muscle synthesis and maintaining a positive nitrogen balance. Also, glutamine supports the secretion of the Human Growth Hormone (HGH), leading to lean muscle mass gain and fat loss.  
  4. Healthy gut: Lack of glutamine can affect intestinal health significantly. People suffering from severe gut issues like leaky gut or Inflammatory Bowel Syndrome (IBS) can go for L-glutamine supplements to improve the symptoms and gut functioning. Glutamine serves as fuel for synthesizing the gut lining that acts as a protective barrier between the small intestine and external blood and prevents the entry of harmful toxins and pathogens. Go for Nutrabay Pure L-Glutamine, the best glutamine supplement for leaky gut. 
  5. Support Rehydration: Muscle cramp is a common issue faced during intense workouts due to sweating and sodium excretion. Some studies also indicate that glutamine might help prevent sodium loss, dehydration and muscle cramps when consumed during a workout or post-workout in the presence of glucose. 

When to take glutamine?

Glutamine supplements are widely available in powder, tablets or capsules. Beginners can take 5 grams of L-glutamine tablets or powder before or after the workout. However, pro athletes can also go up to 30 grams of glutamine per day, divided into three dosages. Ten grams each before, during and after the workout. 

Pregnant or lactating women or people with existing medical conditions must take medical advice before starting the glutamine supplement.  

Are there any side effects of taking glutamine?

Long-term oral glutamine supplementation is associated with no adverse effects and is absolutely safe. Numerous studies have been administered to assess the same, and an intake of approximately forty-five grams for six weeks reported no glutamine side effects.
