  • Speeds up nutrient transport in the body
  • One of the most important indispensable amino acids
  • Formula enriched with vitamin B6 (pyridoxine)
  • Improves post-workout recovery
  • Boosts physical performance
  • Improves the body’s immunity

Extensor L-Glutamine is a dietary supplement which replenish the body with L-glutamine, one of the most important amino acids required for normal functioning of the body. The product features the highest purity of the raw material (the manufacturer declares 99.99% of the active ingredient) without any fillers and flavour enhancers. It contains also extra vitamin B6 as pyridoxine, required for normal metabolism of nitrogen compounds, especially in the case of their increased intake, which is a part of everyday life of individuals involved in sport in general.

L-Glutamine is responsible for supporting many bodily functions, among other things:
Protects the cardiovascular system – it functions primarily as a preventive measure for ischaemia and helps treat reperfusion injury. What is more, when it was used after a cardiac surgery (connected with cardiopulmonary bypass), it decreased damage markers of the body. This is related to studies about mechanisms of increase in glutathione concentration (one of the most important compounds of the body’s antioxidant system) and support for the expression of heat shock proteins.

Reduces inflammation – one of the defense mechanisms of the body is the response of leukocytes. Because of that, their adequate amount is a key factor for an effective anti-inflammatory response. The nourishment of leukocytes is glutamine which they cannot synthesise themselves and is necessary for their normal proliferation (the process of cell growth and maturation). To summarise, adequate glutamine levels are critical to the body’s leukocyte response to inflammation.

Supports the body during training – this effect is especially important during long-term physical activity. During 2-hour workouts, there was a noticeable decrease in glutamine levels in the body. Replenishing this nutrient is essential to maintain normal defense mechanism during physical activity (maintenance of adequate levels of IL-6, one of the most comprehensive interleukins stimulating the body’s defence mechanisms).

The studies have confirmed also an anticatabolic effect of glutamine because less amino acid were precipitated for glutamine conversion and leucine loss was minimised during emergency supplementation. It improved also glycogen restoration in combination with carbohydrates, since it maximises insulin release, which is required for speeding up glycogen synthesis and transport of nutrients in the body, including their supply to muscles.

Mixing studies describe intensified synthesis of muscle proteins. They show that it promotes this process during diseases or when we start training regularly after a longer break.

Supports the digestive system glutamine increases the synthesis of proteins in the digestive system (in particular intestines; essential to regenerative processes), improves intestinal tightness and permeability of nutrients. It contributes also to increased water absorption in the intestines (support for adequate hydration of the body). It may support also the body in the case of Crohn’s disease.

Glutamine is also used widely for serious diseases during hospital care. Requirements for this amino acid are particularly high in the kidneys, immune cells and intestinal mucosa to prevent emaciation of the body.

Glutamine is fortfied with vitamin B6 as pyridoxine whose demand should be higher as the consumption of protein or other amino acids increase because it is involved in the metabolism of amino acids. The recommended daily intake is on average 15 mg of vitamin B6 per 1 g of protein. In addition, it is responsible for normal conversion of precursors into the active dopamine and healthy serotonin levels.

It may help lose body fat and reduce cortisol and prolactin levels.

To sum up, Extensor L-Glutamine is a perfect suggestion for individuals seeking support for the body’s recovery during hard workouts and who also do not like any unnecessary additives in used products. It is a product of the highest quality for all persons who want only the best solutions.

Fat is an essential nutrient plant and animal organisms. Because of the nutritional value and composition of fats are divided into: saturated (mono-saturated and multi-saturated fatty acids) and unsaturated fatty acids (including essential fatty acids - EFA). The group of lipids include lipids (triacylglycerols, waxes), complex fats (glycolipids, phospholipids), sterols and isoprenoids. Saturated fatty acids is a group of fatty acids having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is bound by a single bond. May adversely affect the lipid profile, so they can be used in limited quantities. Fats are a concentrated source of energy, with different flavours, facilitating the consumption and swallowing of food. They have building functions (part of cell membranes and co-create the white matter of the brain). EFAs are precursors of tissue hormones and biologically active compounds. The unsaturated fatty acids include fatty acids from the group Omega-3, Omega-6 and Omega-9 (the last digit indicates, on which, counting of the end of the chain, there is a double bond in the appropriate carbon chain. The essential fatty acids include: acids, medium-Omega-3 [n-3 ] included in EFAs [essential fatty acids], and long chain (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) Omega-6 and Omega-9. the number indicates that the last double bond in the carbon chain is on the third from the end carbon atom. The acids from the omega 3 group are essential components of cell membranes, they are precursors of eicosanoids and biological activators. They must be combined with ingestion in suitable proportions of Omega-6 acids.
Dosage: Depending on demand and applied diet. It is generally accepted that fats should constitute 20-30% of the energy (calorie) of meals daily.




Carbohydrates are an essential nutrient. They are divided into: simple sugars (monosaccharides), disaccharides and polysaccharides. In terms of the human bioavailability of carbohydrates is divided into: digestabe, those which are digested in the gastrointestinal tract by transferring energy to the tissues or cells (such as starch, fructose) and indigestable, resistant to digestive enzymes (e.g. cellulose) . Affects blood glucose levels (glycemic index) and the metabolism of insulin (insulin index). The greatest demand for carbohydrates occurs before physical activity or in the middle of it, because they increase the exercise capacity, consumed after exercise provide regeneration. In the sports diet the absorption rate it is important of carbohydrates and reactions of the organism. Available in mono-preparation supplements and part of the energetic supplements, creatine stacks, nitrogen boosters.
Dosage: according to the statistics of the Institute of Food and Nutrition, carbohydrates should comprise about 50% of daily energy intake. In some diets, used
residual carbohydrate consumption, not exceeding 30g / 24h.




Calories are the conventional name of the unit expressing the energy value of food, the demand and energy expenditure in human body, which in fact is 1 kilocalorie (1 kcal). 1 kilocalorie is the amount of thermal energy required to heat 1 g of water and 1 degree Celsius. The SI unit of thermal energy is 1 joule (1J), equal to approximately 4,185 kcal.
The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents. Most often Atwater equivalent is used: ratio for protein 4 kcal / g, for carbohydrates 4kcal / g, and for fat - 9kcal / g.
The energy value carried out with the so-called. "Caloric bomb" is equivalent to the physical energy, amounting to 4.1 kcal per 1 g carbohydrate to 5.65 kcal per 1 g protein, 9.45 kcal per 1 g of fat.
Nutritional value, determines the suitability of a food product for realizing life functions of human, the higher it is - the higher bioavailability and lower quantity for consumption for obtaining the effects.
