You usually can get enough BCAAs just with the meat you eat, and alot of protein shakes come with addition BCAAs added, like mine has about 8 grams per shake, and don't rely so much on the supplements, food is the best supplement you can take, and 3 shakes a day isn't necessary, just eat and you'll be fine. I am not saying to stop with the shakes, you may need the shakes to get your necessary nutrients, all I am saying is don't think they are some magical form of health elixer...
