7Nutrition BCAA 100% 500g
7Nutrition BCAA 100% is a dietary supplement containing branched-chain amino acids L-leucine, L-isoleucine, and L-valine in the classic 2:1:1 ratio, which is considered in scientific literature to be the closest to the natural metabolic requirements of skeletal muscle. BCAAs belong to the group of essential amino acids, meaning that the human body is unable to synthesize them on its own and they must be supplied through the diet. Branched-chain amino acids constitute a significant portion of the muscle amino acid pool and are largely metabolized directly in muscle tissue rather than in the liver, which distinguishes them from most other amino acids.
Characteristics of BCAA amino acids
L-leucine
Leucine plays a special role in muscle protein metabolism. It is a signaling amino acid involved in the activation of the mTOR pathway, which is responsible for regulating muscle protein synthesis. Studies indicate that leucine is a key amino acid initiating anabolic processes in skeletal muscle after physical exercise and following protein intake.
L-isoleucine
Isoleucine participates in muscle energy metabolism and the regulation of glucose homeostasis. It is both a glucogenic and ketogenic amino acid, meaning it can be used as an energy substrate under conditions of increased metabolic demand.
L-valine
Valine contributes to maintaining nitrogen balance in the body and is part of the amino acid pool used in metabolic processes occurring in muscle tissue. It is an important structural component of muscle proteins and participates in energy metabolism during physical exertion.
The role of BCAAs in the body
According to scientific data, BCAA amino acids:
- constitute a significant portion of the amino acids present in muscle proteins,
- are intensively utilized by skeletal muscles during physical exercise,
- participate in the regulation of muscle protein synthesis and breakdown,
- are involved in energy metabolism under conditions of increased demand.
Why the 2:1:1 ratio?
The 2:1:1 ratio (leucine:isoleucine:valine) is the most commonly used and best-described BCAA proportion in scientific literature. The increased amount of leucine reflects its unique regulatory role in protein synthesis processes, while maintaining the presence of the remaining branched-chain amino acids necessary for metabolic balance.
