Activlab EAA Xtra is a unique supplement containing a mixture of exogenous amino acids, which are crucial for body regeneration, and a set of B vitamins, which support weight training and optimise functioning of the whole body. The product is ideal as a dietary supplement of active people who want to provide themselves with the best possible conditions for improving their strength, endurance and health.

Exogenous amino acids, also called EAA (Essential Amino Acids) is a group of 8 amino acids of great importance for every person, especially for athletes. The body is unable to synthesize these compounds on its own, therefore their high supply together with diet or supplementation is extremely important. They are so important to the human body, because they are a basic element of skeletal muscles, as well as many other tissues. They are necessary for many processes taking place in the body, allow the formation of some hormones and can serve as a source of energy. They can also reduce fatigue during training. In addition, some of them significantly affect our mood, being the precursors to important neurotransmitters, such as serotonin and melatonin.

EAA anabolic properties
To increase muscle mass, it is necessary to meet 3 basic conditions: provide the muscles with an appropriate stimulus, fulfil higher energy demand and supply a lot of good quality protein. The term ‘good quality protein’ refers to the type of amino acids it is made of. To maximise muscle growth, you gave to provide yourself with high supple of BCAA amino acids (Branched Chain Amino Acids), which are leucine, isoleucine and valine, being also part of EAA. They are responsible for activation of mTOR kinase, which initiates muscle protein biosynthesis leading to muscle growth. Appropriately high amount of amino acids in the diet may contribute to the improvement of the nitrogen balance in the body, which also results in faster regeneration and thus increase in muscle mass.

Protection against muscle catabolism
During weight reduction, the body tries to maintain the energy balance through the breakdown of its own tissues (mainly fat cells), which is obviously a desirable effect. However, catabolic reactions may also affect muscles, thereby reducing their hard-earned volume. High content of wholesome proteins may, however, counteract this phenomenon, therefore it is worth making every effort to ensure that the proteins consumed are of the highest possible quality. Taking EAA can be an excellent way to supplement protein in general or its types with a worse aminogram, as it contains essential amino acids.

Higher level of energy and endurance
Another argument for supplementing EAA is the ability of these amino acids to boost energy level during physical effort. Taking the supplement before training allows to do more repetitions and decreases fatigue. In this way an athlete is able to complete a heavier training, which will stimulate his muscle mass to grow even more, or - in case of reduction - will be a signal to keep up the existing muscle mass.

Group B vitamins contained in the supplement support functioning of the nervous and circulatory systems and boost anabolic potential. This vitamin group is characterized by an extremely wide spectrum of activity in the human body, which is related to the role of cofactors in the enzymatic reactions performed by these compounds. It is also worth adding that some of them have an anabolic effect, such as vitamin B12 contained in this preparation as 5'-deoxyadenosylcobalamin. This substance has been the subject of many studies in terms of supplementation improving sports performance from the mid-20th century.

In addition, these vitamins improve the condition of the skin, hair and nails, and pantothenic acid (also known as vitamin B5) is ideal to alleviate acne and other skin diseases. The manufacturer has ensured excellent absorption of the included vitamins by using advanced forms that absorb more quickly and show greater bioactivity. It is also worth adding that 1 portion covers 50% of the demand for all basic B vitamins.

To sum up, Activlab EAA Xtra is a supplement in the form of easily soluble powder, dedicated to active people who want to speed up the achievement of their dream figure and ensure high level of energy during training.

Isoleucine is an essential branched amino acid (BCAA), leucine-isomer. It has anti-catabolic action ( protects muscle against decay), glucogenic (an alternative energy source when the level of glucose after exercise decreases, helps for the regulation of blood glucose levels, reduces the deficiency of fatty acids), anti-catabolic (muscle protects against decay), reduces stress. It participates in the synthesis of proteins (including the synthesis of hemoglobin). It is an essential part of the regeneration of damaged tissues of the body, and after intense training. It occurs in products containing animal protein (meat and dairy products, eggs, dairy products) and plant (almonds, walnuts) and dietary supplements.
Isoleucine is applied with other branched chain amino acids: leucine, valine, and in the supplement complex type of BCAA, in the proportions: leucine: isoleucine: valine = 2: 1: 1. The supplements used in competitive sports requiring increased strength, the bigger share of isoleucine is used.
Dosage: No standard daily use. Frequently applied directly after the workout during the decrease of the glucose level of or at fatty acid deficiency.




Leucine is an essential amino acid, one of the three branched chain amino acids, ketogenic, its isomer is isoleucine. It affects the secretion of anabolic hormones (insulin, combined carbohydrates), acts on enzymes (mTOR) starting the process of muscle protein synthesis and controlling its course. Protein synthesis by leucine is affecting the development of bones, muscles and skin. It reduces the fat tissue. Without the availability of leucine, protein synthesis is impossible. It naturally occurs in animal products (such as eggs, meat, dairy and fish), plant origin, and as a post-training supplements, BCAA, EAA, no-boosters, creatine stacks, carbohydrate supplements. Ir is also in the form of mono-preparation supplements. It is one of the most important amino acids for the athlete's body, basically in every sports discipline.
Dosage: The demand is 5-10 g / 24h, dosage pre- and post-workout and in the morning after waking up.




Lysine belongs to the group of 9 essential amino acids delivered into the body from outside (with food or as a supplement) .It is a building substance of protein (the muscle protein). It is available in food of animal origin (meat, dairy products) and vegetable (legumes). It plays an important role in many physiological processes (absorption of calcium, production of enzymes, hormones and antibodies), and arginine is a component of supplements that increase the synthesis of growth hormone (HGH stimulators). In the form of hydroxylysine (a component of collagen) recommended for the treatment of sports injuries, and prevention. In the case of stress and excessive physical and psychological overloads, it is recommended due to the function of lowering cortisol levels. Also it applies in medicine, in the treatment of anxiety and herpes. The share of lysine intake of daily doses of amino acids should not exceed 5.1%. Available for purchase at
In the processes of digestion of protein matter, as a result of decarboxylation of lysine, may be converted into cadaverine (biogenic amine) having a strong toxicity.
Dosage: the lack of a well-defined standard daily intake of lysine. The supplementation dosages regularly used: with arginine 500 mg - 2g (before bedtime) pre- and post-workout optionally with other amino acids.



Exogenous methionine is an amino acid containing sulphur in its composition. It provides multi metabolism, with the indispensable help of vitamin B6. Participates in the synthesis of phospholipids (e.g. Lecithin), carnitine responsible for transport in the body of long-chain fatty acids, burned in the mitochondria cells (organelles in cells with a separate kernel), along with cystine forms cysteine. It is in the body antioxidant function. Natural source of acquisition of methionine are high-protein foods of animal origin (eggs, meat, fish), vegetable (sesame seeds, grain products). Available in all protein and carbohydrate protein and amino acid supplements such EAA and contain so-called all-day amino acids, supporting the liver preparations and cosmetics supporting the growth and condition of hair, skin and nails.




Phenylalanine (essential amino acid) is provided from the outside with food or synthetic products. Its source are the high-protein foods and supplements, concentrates: protein, amino acid and nutritional supplements for athletes. Precursor of tyrosine, thyroid hormones and neurotransmitters (adrenaline, noradrenaline, dopamine), phenylethylamines (neuromodulator) and melanin pigments of hair and skin. Essential for the proper functioning of the nervous system. It has analgesic, antidepressant, and is used as an additive to supplements with thermogenic and stimulating action. It is a component of aspartame.
Excess phenylalanine consumed by people with neurological problems, may reduce the availability of other essential amino acid tryptophan of nervous system and consequently lead to a reduction in serotonin and exacerbate the depression.



Threonine - essential amino acid, or synthesized from food or (and) in the form of supplements. It takes part in the production of new muscle proteins. It is essential for the proper formation of the immune system is maintained in good condition the skin, bones. It affects the normal development of the enamel of teeth and the digestive system by acting positively on the liver and gastric mucosa. It is essential to the proper functioning of the nervous system. On the Polish there are no threonine mono-preparations. Available in the form of blends of amino acids (e.g.the type of EAA) and natural protein supplements.
Deficiency of threonine can cause neurological disorders and increased depression.
Dosage: the lack of standards of daily demand threonine. Doses customarily used in the supplementation.



Valine – is a branched essential amino acid, indispensible for the functioning of the nervous system (receiving of sensory information), involved in muscle protein synthesis and energy generation. Administration of additional doses of valine before exercise (or immediately after) has anti-catabolic effect, protecting the proteins and allowing them to rebuild. It is slightly stimulatory (delays symptoms of fatigue during workout), affecting the level and relations of neurotransmitters. It helps to protect the liver. It stimulates an increase in strength and muscle mass, participates in the reduction of body fat. BCAA, EAA, and other mixtures of amino acid supplementation, protein and protein supplements and carbohydrate-stacks, brings positive results in strength and endurance sports.
Valine deficiency can occur in case of increased energy needs of the body,
as the result of stress and too much stress load.


Vitamin B6


Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine) is soluble in the liquid. It participates in the metabolism of proteins, fats and carbohydrates. By reducing the amount of fat in the blood do not enable deposition of the body. It helps the absorption of magnesium and vitamin B12 (cobalamin). It works on the muscle antispasmodic and anti-inflammatory pain in the joints. It acts anti. It provides efficient operation of the brain. It increases energy increasing vigor of a man. The demand for vitamin B6 increases during pregnancy and breast-feeding infants. The natural product is: yeast, eggs, wheat germ, meat (liver), wheat bran, nuts, peanuts peanuts, soybeans. There is a hypothesis that can be synthesized by intestinal bacteria.
Deficiency of vitamin B6 causes abnormal metabolism of proteins, decrease in lymphocytes in the blood, causes a feeling of lethargy and fatigue intensifies.
Dosage: 1.5-2.5 mg daily (increased demand during pregnancy and lactation).




Biotin (vitamin H, co-enzyme R) is in a group of B vitamins, due to the presence of sulphur compounds it is involved in the synthesis of ascorbic acid (vitamin C). Also synthesized in the intestines. It enhances the production of hormones and regulates cholesterol levels. It reduces muscle pain. It prevents hair loss and graying of hair. It soothes the skin inflammations. No toxic effects. Often combined with other B group vitamins and vitamin A. The natural sources of biotin are: whole grain bread, yeast, eggs (yolk), milk, brown rice and cheese.

Daily demand: 100-300 mg per day


Folic acid


Folic acid - also known as vitamin B9, is a synthetic form of naturally occurring folates. It needs to be transformed to folates in order to be biologically active also in the human organism. Therefore, its supplementation is recommended to people who do not have problems with methylation processes.

The majority of people associate folic acid with the period of pregnancy. It is definitely a justified association. Proper supply of vitamin B9 conditions correct development of the fetus and prevents disorders of neural tube defects in a baby.

Supplementation with folic acid also demonstrates positive influence on the functions of the nervous system of adults. Some sources say that it is conducive to maintaining beneficial emotional states. Moreover, folic acid takes part in the process of erythropoiesis, thanks to which it enables efficient production of red cells.

Supplementation with folic acid should be also considered by men who deal with low sperm quality. It was proven that complementing the level of vitamin B9 is conducive to increasing reproductive abilities of men.
