Branched-chained amino acids (BCAA) are amino acids having alphatic side-chains with a branch ( a carbon atom bound to more than two carbon atoms. Among the proteingenic amino acids,there are three(3) BCAA’s ; leucine,isoleucine,and valine. This group of amino acids help maintain muscle tissue; they are also needed times of physical stress and intense exercise.
The BCAA’s are among the nine(9) essential amino acids for humans, accounting for 35% of the essential amino acids in muscle proteins and 40% of the performed amino acids required by mammals. Some weight lifters believe that consuming a higher percentage of BCAA’s is better for increasing lean muscle mass than consuming proteins with relatively fewer BCAA’s. Athletes involved in intense training may often taken 5 grams of leucine,
4 grams of valine, and 2 grams of isoleucine per day to prevent muscle loss and increase muscle gain.
The human body cannot produce these essential amino acids that’s why in order to have these,we need to eat protein rich foods. Dairy and red meat are good sources of BCAA’s.
And it’s best to take BCAA along with whole proteins such as lean meat or poultry, as well as multiple vitamins and minerals,especially with B group vitamins.
