Just wanted to save all of you out there a few bucks who supplement with BCAAs, with the expectation of more gains from them.
This video hits the nail on the head (http://www.youtube.com/watch?v=5mdJOgbdlV4)
, and it's exactly what I've thought myself all along, albeit more detailed.
BCAAs are simply building blocks of protein, therefore protein will surely contain BCAAs. As IceCreamFitness says in this video, protein contains 20-25% BCAAs already. He goes on to explain that even if one would consume less protein than 1g/1b bodyweight, they could still get the amount of amino acids that are necessary to facilitate muscle growth. The only situation where consuming a BCAA supplement would be effective, would be for a vegan who takes in very, very little protein.
Moral of the story: 99% of the population does not need BCAA supplements. Just putting that out there.
Edit: his math was a bit off in the link I posted, here is his correction (http://www.youtube.com/watch?v=KddKF8YGyto)
. No big deal, the point still stands.
