What is L-glutamine powder?

L-glutamine is a semi-essential amino acid that plays a central role as a building block for proteins throughout the body. As a dietary supplement, the active ingredient is offered in powder form because the dosage can be adjusted flexibly that way.

  • This amino acid makes up around 60% of the free amino acid pool in skeletal muscle
  • The body can produce it itself, but under high demand its own production is not always sufficient
  • The nutrient is involved in numerous metabolic processes, from the muscles to the immune system

The amino acid L-glutamine in sports and muscle building

In sports, the demand for this amino acid rises quickly. During intense training, muscle cells use up the reserves in the blood and in the muscles faster than the body can replenish them. If you are deliberately investing in muscle building and recovery, you should keep an eye on your own L-glutamine supply.

In the muscles, this nutrient is the most abundant free building block. The cells of the immune system and the gut also have a high demand for this amino acid. The higher the training intensity, the faster the body's own reserves are depleted.

For athletes who train regularly, targeted supplementation can secure the supply during periods of exertion. The recommended daily dose is 5g per day.

NanoPure® process: origin and manufacturing

The NanoPure® process developed by GN Laboratories relies on plant-based fermentation instead of chemical synthesis. What that means for you:

  • Purity above 99%, because no chemical residues from synthesis are produced
  • Completely plant-based: fermentation from corn starch, no animal-derived components in the entire process
  • Nothing unnecessary: no sugar, no flavorings, no colorings, no sweeteners, no anti-caking agents
  • Every batch is lab-tested for purity and quality

The result is a pure, taste-neutral powder that is equally suitable for vegans and athletes.

Taste, solubility and use

The powder has an almost neutral taste and can be combined in many ways. Here's how to use it best:

  • Add one scoop to your protein shake and shake well. Dissolves within 30 seconds.
  • Stir 5g into 200-300ml of water. Room temperature works best, as it improves solubility.
  • The powder stirs easily into smoothies, quark or yogurt. The neutral taste goes unnoticed there.

Frequently asked questions about L-Glutamine Powder

What is L-glutamine powder?
L-glutamine powder is a dietary supplement that supplies this semi-essential amino acid in pure powder form. Of all amino acids, it is the most common free building block in the human body and is particularly concentrated in the muscles. The powder form allows flexible dosing and can be easily stirred into drinks.

How do you take L-glutamine powder?
Dissolve one measuring spoon (5 grams) in 200-300 ml of water or a shake and drink. The ideal time for athletes to take it is directly after training to replenish the amino acid pool. As a daily supplement, the powder can also be stirred into smoothies, yoghurt or quark.

What does L-glutamine powder do?
L-glutamine supports the body during periods of stress by replenishing the amino acid pool. The amino acid has an influence on numerous metabolic functions. It supports the build-up and formation of proteins in muscle cells, is used by immune cells as an energy source and is a fuel for the cells of the intestinal mucosa.

Is this a vegan L-glutamine powder?
Yes, 100%. GN Laboratories produces NanoPure® L-Glutamine by fermentation from corn starch of plant origin. No animal ingredients or additives are used in the entire manufacturing process. The product is also free from additives.

How do I store L-glutamine powder correctly?
Store dry, cool and protected from light at room temperature. Close the can tightly after each use to prevent moisture from penetrating. Under these conditions, the powder remains stable until the stated best-before date.
