The Best Branched Chain Amino Acids or BCAA’s for Men and Women 2020!

BCAAs or branched chain amino acids refer to a group of amino acids (leucine, isoleucine, and valine) that cannot be produced naturally within our body. As one of the top-recommended supplements for CrossFit, it is recommended to supplement BCAA for women and men in order to stimulate protein synthesis, aid in recovery, and in some cases prevent fatigue.

Of the three amino acids of BCAAs, leucine is considered the most important as it drives protein synthesis which is crucial for muscle repair and the development of new muscle growth.

Isoleucine assists with glucose absorption into cells which supplies muscle tissues with energy during intense or extensive workouts, valine also does this but to a lesser degree.

You can and do obtain BCAAs through foods such as eggs, meat, whey protein, etc but it takes hours to digest and you may intake negligible amounts. That is why supplementing BCAAs is crucial as they require no digestion and can be rapidly absorbed into the bloodstream which results in an immediate energy source and muscle aid.
