recommended use:

Take 1 tablet in the morning on an empty stomach, 1 tablet prior to a workout and 1 or 2 tablets after the workout. On non-workout days, take each tablet between meals.


Due to aggressive promotion of BCAA, the role of other amino acids has become somewhat neglected, if not forgotten. When you are on a low-carb diet or engaged in a long, intensive workout, you will certainly run low on glycogen. The combination of hungriness and exercise stimulates protein breakdown. When exercising your muscles, you do not only expect to maintain them. You want to increase their mass. This is why MUST AMINO SPORT proves indispensable.

As a result of breakdown, amino acid compounds can be metabolized to CO2 and H2O or used in gluconeogenesis (glucose formation). Amino acids can be divided into two groups according to their catabolic pathways – gluconeogenic amino acids (catabolized to pyruvate, α-ketoglutarate, succinyl-CoA, fumarate or oxaloacetate) and ketogenic amino acids (catabolized to acetyl-CoA or acetoacetate), also known as precursors of carbohydrates (glucose) and ketone bodies. Both BCAA and EAA are involved in anticatabolic protection, though a bigger role is played here by BCAA, especially due to their leucine administration. Many studies show the important role of BCAA in mitochondrial biogenesis, cell energy metabolism, and ROS scavenging systems because of their modulation of the mTOR/eNOS pathways. Thus, intake of BCAA, especially prior to workout, limits muscle breakdown and/or provides glucose as a source of energy for muscles. Since glucose is released to the bloodstream, it does not have to be drawn from muscle proteins to cause their breakdown. This is the reason why taking BCAA is preferable prior to (about half an hour) or during workout (especially at the beginning). This plays a key role during long, intensive exercises lasting for at least two hours. If you are a long distance runner, race walker, cyclist, swimmer, mountaineer, etc., supplements such as MUST AMINO SPORT are a must.

One desirable effect of using BCAA is to prevent the utilization of glucose and initiate the anticatabolic state. Another one is to achieve a strong anabolic effect, and this is where EAA come into play. In simple terms, the anabolic effect occurs when synthesis of protein is faster than its degradation (or catabolism). During exercises and shortly after them, the blood flow is greater than when resting. This is reflected in a higher protein synthesis, which in turn prefers to utilize EAA to make muscles grow. Generally speaking, BCAA, which are a part of EAA, are preferred for the anti-catabolic effect while the remaining EAA are preferred for the anabolic effect. When using both types separately, BCAA should be taken before while EAA after workout. EAA taken after workout facilitate regeneration and are irreplaceable in the case of vegans, who use plant proteins, deficient in the amino profile.

SAA (Silk Amino Acids, which include L-alanine, L-glycine, L-serine, L-valine, L-threonine, and others, whose content does not exceed 2%) are derived from hydrolyzed glycoprotein extracted from cocoons of the silkworm (Bombyx mori) and have long been valued in cosmetology (e.g. anti-wrinkle creams). Recent studies on mice reveal SAA’s potent role in increasing stamina and boosting testosterone levels. This is most of all beneficial for increasing energy and endurance, and is believed to have a reflection in human bodies too, though studies are still in progress.

MUST AMINO SPORT includes all other amino acids (AA), such as L-glutamic acid, L-aspartic acid, L-proline, L-thyrosine, and L-arginine. They facilitate recovery, provide a neurotransmission boost, stimulate the secretion of hormones involved in muscle development, help in performance during stressful periods, and regulate blood pressure and circulation via nitric oxide.

When confused whether to use amino acids or a protein shake, which amino acids to use and at what times, or if wonder how to fix a drink or shake when you are busy, you definitely need MUST AMINO SPORT. It solves all your concerns, providing the most complete source of amino acids on the market (SAA + BCAA + EAA + AA). In addition, it is available in the form of easy-to-consume tablets that can be taken wherever and whenever you need. If you are an active person, MUST AMINO SPORT is a supplement you simply MUST have.
