Active Ingredients & Science
The active ingredient in this supplement is L-glutamine in free form, an amino acid that is easily soluble and quickly absorbed by the body. Since L-glutamine is not bound to proteins or peptides in this product, it allows for smooth absorption and flexibility in usage. L-glutamine is one of the most common free amino acids in the body and plays a role in several physiological processes, including as a nitrogen carrier and as a precursor to important molecules. The product contains no added flavours or fillers, providing a pure and clear source of this specific amino acid.
Benefits & Uses

- Easy to mix: The powder form makes it simple to mix with water, juice, or your own nutritional shakes.
- Convenient for active individuals: Suitable for people who train or have increased amino acid needs in everyday life.
- Compatible with other supplements: Since the product is free from flavours and fillers, it can be combined with other dietary supplements without affecting taste or composition.
Usage & Dosage
The recommended dosage is 5 grams of L-glutamine per serving, equivalent to one scoop of the powder. It can be taken at any time during the day, with or without food, depending on your routines and needs. For optimal solubility, it is recommended to mix the powder in water or another preferred beverage. Many choose to take it after training or at other times when they want to ensure a stable amino acid intake. The product can also be combined with other amino acids or protein supplements for a broader nutritional profile.
