BCAA PRO 4:1:1 200 Tablets by YAMAMOTO

BCAA PRO 4:1:1 by Yamamoto Nutrition is a blend composedof 100% pharmaceutical-grade, certified branched-chain amino acids(BCAAs) obtained throughplant fermentation, in a 4:1:1 ratio. Branched-chain amino acids (BCAAs) are three amino acids that belong to the group of essential amino acids—those that the human body cannot synthesize on its own in sufficient quantities to meet its needs and must therefore beobtained through the diet. It is important to remember that BCAAs are part of the essential amino acids (EAAs), and that amino acids are the organic molecules our body uses to formproteins.

The formula is also enriched withvitamin B1,whichsupports normal energy metabolism, andvitamin B6,whichhelps reduce tiredness and fatigue and maintain normal protein and glycogen metabolism.

BCAA PRO 4:1:1 features a 4:1:1 ratio of L-leucine, L-isoleucine, and L-valine, meaning itcontains a higher proportion of leucine: this amino acid is, in fact,essential for protein synthesis. Below are the main characteristics of these three amino acids:

• Leucine: It occurs naturally in milk, corn, chicken, and eggs. It plays an important role in muscle function and serves as an alternative energy source during intense physical activity.

• Isoleucine: It is found primarily in corn, potatoes, chicken, eggs, peanuts, bresaola, and lamb. It is closely linked to glucose requirements (it is, in fact, classified as a glucogenic and ketogenic amino acid), prevents the breakdown of structural proteins, and promotes recovery after prolonged physical exertion.

• Valine: It is found in abundance in egg white powder, soy protein, spirulina, and dairy products. It plays an important role, particularly in tissue repair.

BCAAs are one of the most popular dietary supplements among athletes, bodybuilders, and fitness enthusiasts in general. These amino acids are essential for muscle protein synthesis and therepair of muscle tissuedamagedduring exercise.

They account for approximately35% of the essential amino acids in muscle proteinsandare particularly important for maintaining and building lean muscle mass. In addition, BCAAs can helpreducemusclefatigue and improve performance during exercise.

One of the main benefits of taking BCAA supplements is their ability to increase muscle protein synthesis: leucine appears to be the most important amino acid for stimulating muscle protein synthesis, as it activates a metabolic pathway called mTOR.

In addition to their branched-chain structure, another distinctive feature of these amino acids lies in their metabolism. In fact,they are the only amino acids that are not metabolized in the liver but instead pass directly into muscle tissue.There, they are metabolized by the enzyme BCAA aminotransferase, which, as noted, is not present in the liver.
All three branched-chain amino acids are insulinogenic, but unlike other amino acids that stimulate insulin, they are not glucagonogenic. This property has attracted the interest of the supplement market due to the benefits of insulin spikes following physical activity.

Quality comes first

What is a branched-chain amino acid supplement used for?

Branched-chain amino acids have three main functions: they areused for protein synthesis,where—along with the other 17 alpha-amino acids—they serve as the building blocks of proteins; they areused for energy; andthey act as signaling molecules.
