Activlab BCAA Xtra Instant is the highest-quality amino acid supplement, providing high doses of branched-chain amino acids (BCAA) and L-Glutamine. This product is characterized by excellent solubility in water and is very effective in covering the increased demand for branched chain amino acids, especially in people who perform strength sports.
Branched-chain amino acids (BCAAs) are a group of amino acids having branched carbon chains in their chemical structure. This group includes three amino acids: valine, leucine and isoleucine. Below are their properties:
BCAAs inhibit catabolic processes in the body
Branched chain amino acids have the ability to increase the use of fat as an energy source. Therefore, energy is obtained from triglycerides derived from fat cells. Thanks to this, the loss of fat tissue is faster and, what is important in conditions of increased protein demand – the body does not break down the proteins present in our muscles. BCAAs thus prevent the loss of muscle mass due to an insufficient number of calories in the diet.
Increased vitality after a workout
After an intense effort, we usually feel very exhausted. This can be partially reduced by supplying the right amount of carbohydrates before a workout – which will prevent drastic declines in energy after training. Another way is to take this supplement because branched chain amino acids have the ability to lower the concentration of tryptophan, which is a substrate for the synthesis of serotonin responsible for the post-workout fatigue.
Increased protein synthesis and faster muscle mass gain
BCAAs, in particular, L-Leucine, which is the strongest branched amino acid, can significantly accelerate protein biosynthesis. This occurs by increasing the number of calcium ions bound inside the cell by calmodulin. It is a signal activating the mTOR complex that has the ability to intensify protein formation processes that are crucial for the proper functioning and structure of the muscle system.
Like other BCAAs, leucine may also prevent muscle atrophy caused by various diseases and inhibit catabolism.
L-Glutamine is the most abundant protein amino acid in our muscles. It is true that it can be synthesized by our body, but the need for this amino acid increases significantly as a result of physical effort. For this reason, glutamine supplementation is sometimes needed to get the best training results. It supports the building of muscle mass and promotes the renewal of glycogen resources.
Anabolic action of glutamine
Glutamine as a protein amino acid is necessary for the synthesis of all proteins in the body. Similarly to Branched Chain Amino Acids (BCAAs), it can inhibit catabolic processes associated with insufficient glutamine supply. In people experiencing a lot of stress or struggling with various diseases, the demand for this amino acid increases significantly. Its supplementation helps to cover this demand and provide a muscle-friendly anabolic environment.
Faster resynthesis of muscle glycogen
L-Glutamine may in specific cases be a direct source of energy. It is transformed into such organic acids as pyruvic, lactic or lemon. These, in turn, may be included in the Krebs cycle from which ATP is formed or constitute a precursor to glucose in the process of gluconeogenesis.
As a result, by stimulating the formation of glucose in the cell, glutamine contributes to faster replenishment of glycogen stores – to be later used as a source of energy for the work of muscle cells. Faster re-synthesis of glycogen facilitates the regeneration of muscles, so that they may be ready for another workout earlier.
In summary, Activlab BCAA Xtra Instant is an amino acid formula that provides the supply of compounds that help to build good quality muscle mass. The branched amino acids and glutamine present in this supplement support protein biosynthesis and promote muscle regeneration after training. The product dissolves easily in water, making it extremely convenient to use.

Glutamine (L-glutamine) - endogenous amino acid building proteins, glutamic acid amide. In the human body it is responsible for the synthesis of proteins, acid-base balance and removing ammonia from 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. Glutamine has a direct impact on the proper functioning of the digestive system and immune immunity of the organism. Participates in the synthesis of one of the most powerful antioxidant glutathione. It has anti-catabolic potential. It can be found naturally in foods of animal and vegetable origin, protein supplements. Used as mono- or multi-component amino acid supplements, and supplements improving biological recovery after exercise, often in combination with BCAA.
Dosage: 5-20 g per day (portioned during the day, and after training and waking up). The supplementation uses the minimum dose of 2-15g to 1 serving.
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.
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.
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.
