What is BCAA and Its Benefits?

If you are not so fitness conscious then you might not be familiar with BCAA. So for your benefit, let us tell you more about it. BCAA or Branched Chain Amino Acid are useful in gaining weight. These three amino acids namely Leucine, Isoleucine, and Valine are combined together to speed up and increase the size of your muscles as well. Leucine is beneficial in muscle protein synthesis wherein Isoleucine encourages the reception of glucose into the cells.

Taking these three separately is a different story. Combined together they are very powerful and useful.

So what exactly do they do?

What is BCAA

  • It is an enhancer. It enhances muscle protein synthesis. Taking this while you engage in resistance exercises trigger mTORC1 which is vital in muscle building. But even without exercise, the intake of BCAA ensures that fat gain is minimal and it helps the body maintain good metabolism.
  • It is effective in burning fats. BCAA works this way, it increases your muscles while decreasing body fats. One of its key components, Leucine is known to be the best in achieving leaner muscles. It also helps maximize the usage of energy and fat oxidation while Isoleucine does the work with glucose tolerance.
  • It helps improve the maturity of strength while training. Several researches has been conducted and gave similar conclusions. BCAA has been proven to increase strength by about 31% in average on all kinds of exercises. It is highly advisable to take in amino rich foods that are also rich in protein like meat, eggs, protein shakes and supplements to achieve better results.
  • It has the same muscle building effect on both young and old users. Taking Leucine alone may cause imbalance in the blood amino acid levels but taking BCAA makes it balanced. Studies say that protein synthesis is increased by as much as 145% if taken after workout.
  • It decreases fatigue and increases endurance. These are two of the major factors being considered before and during strength training. The training itself increases fatigue and strain in the body and could weaken you. BCAA can be burned as energy during workout thus increasing your energy bank. On the other hand, BCAA prevents tryptophan from reaching the brain. Tryptophan is dangerous since it produces serotonin once reaching the brain. Serotonin on the other hand increases tiredness and fatigue.

  • In addition to improving endurance, it also helps prevent muscle loss during trainings. Tearing of muscles and damages are very common during training due to the dropping of plasma levels. BCAA helps prevent this from happening often, although it is really inevitable.
  • BCAA contains anti – aging properties and are known to increase mitochondria. In some cases, it is also used in the medical field in the treatment of disease like cancer and liver diseases as well as the prevention of muscle loss. This is also helpful in reducing the risks of diabetes. Over all, BCAA can also be used in a therapeutic manner.
