Biotech Glutamine Zero is a post-workout dietary supplement containing as much as 11g of L-glutamine in one portion, that is an endogenous amino acid that allows effective regeneration and increased muscle resistance to damage and fatigue, as well as strengthening general immunity.

The product is in the form of a readily soluble powder available in several flavours. It does not contain aspartame or preservatives. It’s a perfect complement to the diet of any athlete who wants to conveniently provide his body with the highest quality, easily absorbable building material and an agent accelerating muscle recovery.

L-glutamine is the most commonly occurring amino acid in our body, located mainly in the muscles and in the blood plasma. We can partially synthesize it ourselves from glutamic acid, but in some states, such as excessive stress or increased physical activity, the demand for this amino acid increases and it must be additionally supplied from the outside.

Anabolic and anti-catabolic effect of glutamine
Glutamine is a protein amino acid, which means that it’s part of proteins, both those that are building blocks and others, e.g. enzymatic ones. In addition, it’s a substrate for glycine (another protein amino acid). In case of increased demand for glutamine and its insufficient supply in the diet, the body acquires it from skeletal muscles, which can unfortunately stimulate their catabolism. For this reason, it’s extremely important to ensure proper supplementation with L-glutamine to protect muscles from catabolism, especially in physically active persons.

Glutamine is also a nitrogen donor for many anabolic processes and participates in the synthesis of purines and pyrimidines that are part of nucleic acids. Moreover, research shows that increased supply of glutamine intensifies protein biosynthesis in muscle fibres and reduces leucine oxidation, positively affecting its increased amount in muscles. 

An efficient source of energy and easier glycogen renewal
Glutamine can be the second source of energy for cells after glucose, especially for those that are intensely dividing. In a series of reactions of a complex process called glutaminolysis, this amino acid is converted to pyruvic, lactic or citric acid, which are substrates for the reactions from which the cell derives energy (e.g. gluconeogenesis or the Krebs cycle).

Glutamine helps replenish glycogen resources in the muscles, which translates into their faster readiness for training. It’s also the main energetic substrate for bone marrow and leukocyte cells and contributes to the increased rate of their division, thanks to which it can positively affect the condition of the immune system.

In addition, it has been proven that L-glutamine can inhibit sudden, rapid increases in blood glucose and insulin secretion in response to a meal consumed, so that energy supplied with food is released in a more subdued manner and can be used more effectively by the body.

Support for the metabolism of nitrogen compounds and protection against free radicals
Glutamic acid has the ability to bind to toxic ammonia formed, for example, as a result of amino acid transformation. After its binding, it becomes glutamine and forms a reservoir of this harmful compound, which in the form of glutamine can be safely transported with blood.

Thus bound ammonia is then detached and used in the urea cycle for the synthesis of urea subsequently removed in the urine. This way, glutamine and glutamic acid are involved in the excretion of harmful metabolites from the body.

Glutamine is not only an ammonia donor in the ornithine cycle, but also a precursor of citrulline - one of the amino acids also involved in this cycle. Citrulline stimulates the synthesis of nitric oxide in the body and supports the removal of toxic ammonia from the body

In conclusion, Biotech Glutamine Zero is a supplement that provides one of the most important amino acids in our body. Glutamine is a compound with a wide effect. Its most important tasks include promoting regeneration as well as supporting the work of the muscular and immune systems. It’s also a valuable source of energy for many tissues.

Energy value


The energy value is determined by the chemical composition of the food product, by means of the so-called. physiological equivalents energy., determining the value of metabolic energy contained in 1 g of the component. Most commonly used is the equivalent of Atwater: protein 4 kcal/g for carbohydrates 4kcal/g, and for fat 9kcal/g.




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.


Saturated fatty acids


Saturated fatty acids are a group of fatty acid having different carbon chain lengths, in which except for the carboxyl group, each of the carbon atoms is linked by a single bond. Saturated fatty acids are commonly known as bad fat, which might adversely affect the cholesterol level, in particular by the action of acids: lauric, myristic, palmitic, and therefore their consumption should be reduced. Research carried out in this matter do not confirm entirely the prevailing beliefs.




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.




The sugars are the major digestible fuel in the body. We divide them into mono saccharides - glucose (dextrose), fructose (fruit sugar); di- (di-saccharides) - lactose, maltose, sucrose; complex sugars - starch. Most of them changes into glucose during the burning process. Sugars are sweet and increase the glycemic index (except fructose). The healthiest source of acquisition of simple sugars is a diet containing the so-called. products of the first milling and fresh fruit and vegetables in the raw form.


Consumed during a strength workout, they delay fatigue, affecting the proper hydration of the body and keeping parts of glycogen. After finished workout,they accelerate the regeneration of the body and complement energy expenditure. The excess sugars result in the accumulation of excess fat and increase of fatty tissue. A responsible use of sugars is recommended for diabetics, both for hyperglycaemia (glucose level above the normal), and hypoglycaemia (blood sugar levels below normal). Excess consumption of simple sugars can cause tooth decay.
Simple sugars are included in many dietary supplements, most commonly used in the carbohydrate and protein and carbohydrate supplements.
Dosage: for competitive sport athletes it is recommended to consume simple sugars only during workout and immediately after workout.




Proteins (proteins, polypeptides) is a polymer, of which the basic units (monomers) are amino acids. Protein is composed of carbon, oxygen, nitrogen, hydrogen and sulfur, and is an elementary nutrient necessary for the proper functioning of the body, an ingredient and a component of tissues, part of the hormones and enzymes and other bioactive substances. Protein determines the proper metabolism and energy processes, as well as all other life processes. The sources of natural proteins are foods of animal origin (including meat, fish, eggs, dairy products) and plant origin (legumes, soy). Deficiency of protein leads to protein malnutrition and a significant weakening of the body. It can lead to anaemia, reduced immunity, muscle relaxation, disorders of the digestive system. Also, overdose protein is undesirable because it can lead to acidification of the body, and interfere with the digestive system and an increase in the concentration of homocysteine ​​in the blood. It is a component of many supplements and nutrients necessary for the proper functioning of the body, both showing a low physical activity, or training the strength and endurance competitions.
Dosage: strength athletes: approx. 1.7 - 2.5 g / 1 kg of body weight; endurance athletes and strength -endurance athletes approx. 1.3 - 2 g / 1 kg of body weight, people with low activity approx. 0.8 - 1.1 g / 1 kg of body weight / 24h. In estimating the amount of protein, you should take into account the intake of other nutrients (carbohydrates and fats)




Salt (sodium chloride, or table salt), natural source of electrolytes (chlorine and potassium), regulating water and electrolyte and acid-base balance of the body, affecting the nervous system and blood pressure. Sodium is an essential element for the proper growth. The proper dose of salt prevents overheating of the body and solar stroke. It provides the proper functioning of muscles and nerves the body. Chlorine in combination with sodium, is involved in the digestive process and maintains acid-base balance in the body, as antitoxin removes toxic products of metabolism in the liver. Salt is a flavour component and preservative of many foods, nutritional supplements and mixtures of electrolytes, available at

Dosage: no specific standards of consumption, used so as to provide sufficient amount of electrolytes to the body (sodium and chloride).




L-glutamine - amino acid building endogenous proteins, glutamic acid amide. In the human body it is responsible for the synthesis of proteins, acid-base balance and removing ammonia outside of the organism. With the shortage of energy taken from the muscle tissue, glutamine with alanine participate in the process of gluconeogenesis, and participate in the production of glucose substrate. L-glutamine has a direct impact on the proper functioning of the digestive system and immunity of the organism. Participates in the synthesis of one of the most powerful antioxidant - glutathione. It has anti-catabolic potential. It is found naturally in foods of animal and vegetable origin and high protein supplements. Used as mono-preparation or multi-component amino-acid supplements and supplements enhancing biological recovery after exercises, often in combination with BCAA.
Dosage: 5-20 g per day (portioned during the day, and after training and waking up). The minimum dose used in supplementation is 2-15g per 1 serving.
