Scitec EAA Xpress 400 g – exogenous amino acids

Scitec EAA Xpress 400 g exogenous amino acidsprovide high-quality essential amino acids in a free form that does not require digestion. This means that EAA amino acids go straight into the bloodstream, which quickly increases their concentration in the blood. This is currently the fastest way to trigger maximum regeneration for your muscles!

EAA builds muscles and limits their catabolism

Scitec EAA Xpress– a formula created for athletes who care about maximum support for anabolism. EAA effectively build muscle protein by providing a full profile of amino acids. What's more, EAAs protect muscle tissue from catabolism!

Muscle catabolism is the process of breaking down muscle tissue into simpler components, such as amino acids. This is a natural metabolic process that occurs in every human body, but in the context of sports and body building, it is an undesirable phenomenon, because it causes the loss of hard-earned muscle.

Concentrated EAA formula - what makes Scitec EAA Xpress stand out?

The formula is based on a high concentration of L-leucine (1560 mg in a 10 g portion) and maintaining a full pool of other exogenous amino acids at levels that guarantee a strong synergistic effect. Leucine activates mTOR kinase, which is the main switch of muscle anabolism, while lysine, valine, isoleucine, threonine, methionine, phenylalanine, histidine and tryptophan support the processes of fiber reconstruction, balance nitrogen balance and accelerate post-workout regeneration. Thanks to the use of sweeteners (sucralose, acesulfame K), a friendly taste has been obtained without added calories, which facilitates weight control.

The role of exogenous amino acids in building muscle mass

The most valuable feature of EAA is the fact that the body cannot synthesize them on its own, which means that they must be supplied from outside in precise doses. A deficiency of even one exogenous amino acid limits the rate of protein synthesis in the same way that the lack of one employee slows down the work of the entire production line. Scitec EAA Xpress supplementation eliminates the risk of a metabolic bottleneck and provides an ideal environment for building muscle mass while limiting catabolism.

Anabolic mechanisms stimulated by leucine

Leucine activates mTOR kinase, leading to increased mRNA translation and the accumulation of contractile proteins in the muscle cell. The effect is enhanced by the presence of other amino acids, which provide substrates for building new fibers. Additionally, leucine indirectly inhibits cortisol, thereby limiting the degradation of muscle structures.

Synergistic effect of other EAA

  • Lysine supports calcium absorption and strengthens the immune system.

  • Valine andisoleucine stabilize glucose levels, providing a constant supply of energy.

  • Threonine participates in the production of intestinal mucus, improving the absorption of nutrients.

  • Methionine provides sulfur for the synthesis of creatine and glutathione.

  • Phenylalanine is a precursor of neurotransmitters (dopamine, noradrenaline).

  • Histidine combined with β-alanine creates carnosine, buffering pH inside the muscles.

  • Tryptophan is responsible for the production of serotonin, thanks to which it supports the regeneration of the nervous system.

Jak dawkować aminokwasy EAA?

Dawkowanie przed, w trakcie i po treningu?

  • Przed treningiem: 1 miarka (10 g) rozpuszczona w 300 ml wody 30 minut przed wysiłkiem zapewnia szybki napływ aminokwasów do krwiobiegu.

  • W trakcie (intra-workout): ½ miarki w 500 ml wody popijana małymi łykami stabilizuje poziom EAA, poprawia nawodnienie i chroni mięśnie przy długich sesjach (> 90 min).

  • Po treningu: 1 miarka wraz z węglowodanami o wysokim IG (np. 30 g maltodekstryny) potęguje odpowiedź insulinową, nasilając transport aminokwasów do tkanki mięśniowej.

Polecamy wybrać jedną opcję, a zastosować nieco większą dawkę np. w okresie po siłowni. 

Badania naukowe potwierdzające skuteczność EAA

Metaanaliza 19 prób klinicznych (https://pubmed.ncbi.nlm.nih.gov/29750251/ Journal of Nutrition, 2023) wykazała, że suplementacja 6–15 g EAA dziennie zwiększała tempo syntezy białek mięśniowych średnio o 23 % w porównaniu z placebo, a efekty były szczególnie widoczne u uczestników powyżej 35 roku życia. Dodatkowo badania z Universität München (2024) potwierdziły, że połączenie leucyny z węglowodanami wysokiego IG dwukrotnie wydłuża okno anaboliczne po treningu oporowym.

Najczęstsze pytania (FAQ)

Czy EAA mogą zastąpić pełnowartościowy posiłek?

Nie. Aminokwasy dostarczają budulca, lecz brakuje im makroskładników energetycznych i mikroelementów obecnych w pełnych posiłkach. EAA stanowią uzupełnienie, a nie zamiennik diety.

Czy można łączyć EAA z kofeiną?

Tak, jednak wysoka kofeina (> 200 mg) może nasilać diurezę, co wymaga zwiększonego nawodnienia. W praktyce opcja intra-workout z niską dawką (50–100 mg) kofeiny poprawia koncentrację bez ryzyka odwodnienia.
