One of my favourite supplements and amino acids L-Glutamine – it might sound like the name of a science fiction character, but it’s a versatile amino acid with an impressive array of health benefits. Found naturally in foods like eggs, beef, and dairy, L-Glutamine is also available in supplement form, making it even easier to reap its rewards. In this fun and fact-filled article, we’ll explore the science-backed benefits of L-Glutamine and why you should consider including it in your daily regimen as I beleive it is a must if you train regularly.
L-Glutamine is one of the most abundant amino acids in the human body, accounting for about 20% of the total amino acid pool. It’s considered a conditionally essential amino acid, which means that although the body can produce it, there are times when the demand for it exceeds the body’s ability to synthesize it, such as during periods of intense exercise, illness, or stress. In these cases, supplementation can be really beneficial as your body will recover faster and your imune system will be stronger which will allow you to keep pushing boundaries and achieve better results. I alwayes use additional L-glutaminesupplementation on top of my diet when I want to perform better for example if I’m in a period of building strength, muscles or I try to burn more fats.

The Science-Backed Benefits of L-Glutamine

1. Boosting gut health
Your gut health plays a significant role in your overall well-being, and L-Glutamine is here to save the day. Research has shown that L-Glutamine is a primary fuel source for cells lining the intestines and without it, these cells may waste away. This is how L-glutamine promoting gut barrier integrity and reducing intestinal permeability. This helps maintain a healthy gut environment, which in turn supports the immune system and overall health. Glutamine is not only essential for maintaining optimal immune function, but it also plays a crucial role in supporting the function of white blood cells. Animal studies have demonstrated that glutamine possesses anti-inflammatory properties, further showcasing its diverse range of health benefits.
2. Reducing exercise-induced stress
Exercise can be stressful for your body, but L-Glutamine is here to help. Research indicates that L-Glutamine supplementation can reduce the levels of stress hormones, such as cortisol, released during intense exercise. This may help improve overall recovery and reduce the negative effects of exercise-induced stress on the body.
3.Аccelerating muscle recovery and growth
If you’re looking to level up your workouts, L-Glutamine could be your new best friend. Studies have demonstrated that L-Glutamine supplementation can help reduce muscle soreness and promote faster recovery following intense exercise. Additionally, L-Glutamine has been shown to support muscle growth by increasing protein synthesis and reducing muscle breakdown.
4. Enhancing immune function
As a superhero amino acid, L-Glutamine doesn’t shy away from defending your body against invaders. L-Glutamine has been shown to support immune function by providing fuel for immune cells and promoting the production of essential immune molecules, such as cytokines. This makes L-Glutamine a valuable ally in warding off infections and maintaining overall health.

5. Supporting brain function

The big one – L-Glutamine is not only a muscle and immune system booster; it’s also a brain supporter. L-Glutamine is a precursor for the neurotransmitters glutamate and gamma-aminobutyric acid (GABA), which play essential roles in cognitive function and mood regulation. By supporting the production of these neurotransmitters, L-Glutamine may help improve memory, focus, and overall brain health.

Incorporating L-Glutamine into your daily routine is a relatively simple process. You can obtain this powerful amino acid from both dietary sources and supplements. Here are some strategies to help you get your daily dose of L-Glutamine. You can�found in a variety of protein-rich foods, which can be easily incorporated into your daily meals. Some excellent dietary sources of L-Glutamine include:

  • Meat: beef, chicken, pork, and turkey
  • Fish: salmon, tuna, and other fatty fish
  • Dairy: milk, cheese, and yoghurt
  • Eggs
  • Legumes: beans, lentils, and chickpeas
  • Nuts and seeds: almonds, peanuts, and sunflower seeds
  • Vegetables: cabbage, spinach, and broccoli

If you’re struggling to meet your L-Glutamine needs through diet alone, especially during periods of intense exercise, illness, or stress, you may consider taking an L-Glutamine supplement. These supplements come in various forms, such as powders, capsules, and tablets. I prefer using powders as I’m sure its 100% pure L-glutamine. I like Reflex L-Glutamine, usually 500g as it’s the best price to dose ration. During intense weeks the way I intake this supplemtn is 5g in the morning , 5 g 15-20 min before my workout, 5 g immediately after my workout and 5 g before bed but as alwayes you should consult a healthcare professional or a registered dietitian to determine your dosage and the best way for you to top up your L-Glutamine.�
