What is the purpose of BCAA?
You get them from eating protein, and they are what your body uses to build muscle protein. Branched-chain amino acids (BCAAs): BCAAs are a class of essential amino acids that the body can use for energy and muscle synthesis. The branched-chain amino acids include leucine, isoleucine, and valine.
Branch chain amino acids (BCAA’s) consist of leucine, isoleucine and valine which constitute 1/3 of your muscle protein. There purpose is to reduce muscle fatigue and recovery time, help mitigate the loss of other amino acids from the muscle during exercise and help the body absorb and synthesise protein.
How Do Branched-Chain Amino Acids Work?
BCAAs make up a large chunk of the body's total amino acid pool.
Together, they represent around 35–40% of all essential amino acids present in your body and 14–18% of those found in your muscles.
Contrary to most other amino acids, BCAAs are mostly broken down in the muscle, rather than in the liver. Because of this, they are thought to play a role in energy production during exercise.
BCAAs play several other roles in your body too.
First, your body can use them as building blocks for protein and muscle.
They may also be involved in regulating your blood sugar levels by preserving liver and muscle sugar stores and stimulating your cells to take in sugar from your bloodstream.
What's more, BCAAs may help reduce the fatigue you feel during exercise by reducing the production of serotonin in your brain.
Leucine is thought have the biggest impact on your body's capacity to build muscle proteins. Meanwhile, isoleucine and valine seem more effective at producing energy and regulating your blood sugar levels.
