• BETA-ALANINE

• GLYCINE

  Glycine is the smallest amino acid — a building block of proteins and collagen — and at the same time an inhibitory neurotransmitter in the central nervous system. It acts as a ligand for glycine receptors (influencing neural tone and relaxation) and as a co-agonist of the NMDA receptor (synaptic plasticity, learning processes). At the tissue level it supplies substrate for the synthesis of collagen types I and III, and in metabolism it participates in bile-acid conjugation, detoxification and one-carbon cycling. This dual role — structural and signalling — explains why it works well for many supplementation goals.

• GLUTAMINE

• CITRULLINE

• L-tryptophan

  L-tryptophan is an essential amino acid, meaning the body cannot produce it on its own and must obtain it from the diet. In practice, L-tryptophan supplementation is most often chosen by people who want a structured way to support evening calm, sleep quality, and nervous system recovery after a demanding day. It is a solution for those who are not looking for a “strong hit”, but rather consistent support for physiological processes linked to the circadian rhythm and neurotransmitter balance.

• L-TYROSINE

  Tyrosine is a precursor for the catecholamine pathway. Simply put, the body can produce L-DOPA from tyrosine, followed by dopamine and then noradrenaline. The enzyme tyrosine hydroxylase, considered to be the rate-limiting step in catecholamine synthesis, plays a key role in this process. This explains why tyrosine appears in the literature in the context of "performance support" under stress: when the rate of neurotransmitter consumption increases, the supply of substrate may help maintain the efficiency o
