ACTIVLAB BCAA 1000 XXL is a dietary supplement that includes biologically active forms of branched-chain amino acids (BCAA). Each tablet delivers a total of 1000 mg of leucine, isoleucine and valine in the optimal proportions of 2:1:1.
The supplement is one of the most popular products used in sports supplementation. It is recommended for professionals and people who practice sports recreationally. It is beneficial for the improvement of physical capacity and endurance, it may delay the occurrence of fatigue during intensive physical exercise, and significantly speeds up the regeneration of the body.
BCAA (Branched-Chain Amino Acids) are amino acids with branched aliphatic side chain. The group consists of leucine, isoleucine and valine. These amino acids are essential, which means that the body is incapable of their production on its own and the only sources of their acquisition are external. BCAA are accumulated in the organism mainly in muscle tissue and constitute nearly 35% of muscle proteins. Their function is not only structural, but also regulatory. They affect the production of hormones and catecholamines, as well as stimulate protein synthesis. They can also be used as a source of energy.
Improvement of training efficiency
Intensive physical exercise is associated with considerable losses of BCAA, which suggest that the supplementation with this kind of amino acids may have a positive effect on the strength and endurance parameters. BCAA protect the central nervous system against fatigue, which is caused by long-lasting muscle work. Additionally, they positively affect energy processes and protects muscle fibers from the effects of catabolism.
A study compared the effect of BCAA supplementation on muscle strength. A group of 36 men who supplemented BCAA reported an increase in muscle strength, which was not observed in the group who only used protein or carbohydrate supplements. It has also been proven that BCAA supplementation can increase the endurance of athletes. Long distance runners who were given a BCAA supplement achieved much better results in races day after day.
Reduction of psychophysical fatigue
Maintaining a sufficiently high concentration of BCAA in the blood delays the signs of tiredness, that way allowing you to extend your training. This effect is possible thanks to changes in the central nervous system, and the most important role in this process is played by leucine.
Leucine competes with tryptophan for the same transporter and if its supply is high enough, it usually wins this battle. Thanks to this, the uptake of tryptophan in the brain is very limited. Tryptophan is used for the production of serotonin, which is responsible for the feelings of fatigue and tiredness. A decrease of its concentration will somewhat inhibit the production of serotonin, which is very desirable in long-lasting physical exercise because it allows to relieve the feeling of fatigue and exhaustion after a hard training.
BCAA reduce fatigue not only on the mental level, but also on the physical level. They can extend muscle work capacity by providing them with the necessary energy. Both isoleucine and valine can be easily converted into glucose, so after exhausting glycogen reserves, the body can use them as a secondary source of energy.
Improvement of post-workout regeneration
BCAA contribute to reducing some negative structural and metabolic changes associated with muscle damage resulting from strenuous exercise. Thank to that, they reduce the time needed for the biological regeneration of the body.
Researchers have proven that high BCAA concentration in the blood protects against the breakdown of muscle proteins and has a positive effect on the rate of glycogen deposit renewal. BCAA can also stimulate anabolic processes and promote the reduction of excess free radicals, whose significant amounts are produced during intensive physical exercise.
The subjective assessments of BCAA users show that thanks to supplementation, they recover faster after a hard training and experience less delayed onset muscle soreness (DOMS). Thanks to that, physical fitness in the days following intensive exercise is still at a very high level.
In conclusion, ACTIVLAB BCAA 1000 XXL is a supplement that can be recommended to practically any person who is physically active. The product has a beneficial effect on exercise capacity, and supports increased strength and endurance of the body. It also allows to shorten the time necessary for effective post-workout regeneration.
There are no unequivocal guidelines for the dosage of BCAA, but it is worth mentioning that excessive doses may have the opposite effect and decrease the body’s performance. For this reason, it is worth following the producer’s guidelines. Higher doses of BCCA (1 tablet for every 10 kg of body weight) are for professional athletes.
It is recommended that BCAA should be taken immediately after training on training days to reduce muscle damage caused by strenuous exercise.
Research suggests the synergy of BCAA with arginine and citrulline, so to achieve better results, you may complement your supplementation plan with these amino acids.
ACTIVLAB is one of the most respected brands among manufacturers of dietary and nutritional supplements for athletes and people, who have an active lifestyle. Among the company products, you can find carbohydrates, protein and amino acids, which support muscle building.

L-leucine, L-valine, L-isoleucine, bulking agent - microcrystalline cellulose, corn starch, gelatin, anti-caking agent - silicon dioxide.
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.
Dietary fibre is a mixture of undigested substances and not absorbed by the human body. Due to the properties divided into: insoluble fibre (e.g. cellulose [polysaccharide] found in fruits and vegetables), partially soluble fibre (including hemicellulose occurring with cereal grains and soluble fibre (including pectin, gums, mucilages [polysaccharides]). Dietary fibre affects the digestive system and gastrointestinal system regulating its operation. By filling the stomach (satiety) reduces appetite, lowers triglycerides and cholesterol and consequently can support the weight loss process and maintain a slim body. It also affects blood glucose levels and cleansing the body of toxins. Available in powder formulations (capsules, and powders), mainly containing the soluble fraction (pectin, gums and mucilages) diet and meal replacements.
Dosage: 10-20 grams per day, before or during meals with some water.
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)
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.
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.
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.
