GLUTA + is a food supplement that provides 5 g per daily dose of KYOWA brand glutamine, particularly suitable for athletes who practice intense physical exercise. Glutamine is a conditionally essential amino acid, essential for many body functions. In particular, it is involved in protein synthesis, constitutes the main energy source for various cells of the system immune system and is involved in the body's antioxidant protective mechanisms.


Glutamine is a non-essential amino acid that can be synthesized by our body, mainly in muscle tissue starting from the arginine, ornithine and proline amino acids.

It constitutes 60-65% of all amino acids present in skeletal muscle. Glutamine is defined as a conditionally essential amino acid. In fact, although it can be synthesized from other amino acids, under certain stress conditions (such as trauma and particularly intense physical exercise) our body cannot produce sufficient quantities to meet its needs.

At sports level, scientific evidence has shown that endurance athletes who undergo intense training or competition are in a state of psychophysical stress and therefore the body cannot produce sufficient quantities of glutamine.  If the body's glutamine requirement is greater than its ability to produce it, the body itself may use protein deposits to release more of this amino acid. In these cases, glutamine supplementation may be useful to meet the needs of the body.

Glutamine is an amino acid that participates in several physiological reactions:

-it is directly involved in protein synthesis and has anti-catabolic properties

-it ensures the proper functioning of the nervous system, (precursor of glutamate)

- it has a detoxifying action, is useful in the disposal of post-workout toxins, as it promotes the formation of gamma butyric acid and glutathione (powerful endogenous antioxidant).

- it increases the volume of muscle cells, improving hydration and promoting the passage of nutrients that facilitate the biochemical and anabolic processes that take place in these cells.

- it strengthens the immune system, in particular playing a role of energy support in cells involved in defence mechanisms such as leukocytes, macrophages and neutrophils.

-it supports intestinal health thanks to its role on immune system cells, helps to maintain the integrity of the intestinal mucosa and in particular of the colon, preventing increased intestinal permeability.


Mix one serving (5g) with 250 ml of water or fruit juice, and take once a day preferably immediately after exercise.
