An article was just published the other day in which the International Olymmpic Commitee and the International Society of Sports Nutrition concluded that they do not recommend the use of BCAA supplements.
I published a podcast about this
I have been banging the table on this for years. I cannot think of one reason to use BCAA supplements. Instead, use any of my protein powders to increase muscle protein synthesis.
Here is another study for good measure.
Alex Rogers is a supplement manufacturing expert. He has been formulating, consulting, & manufacturing dietary supplements since 1998. Alex invented protein customization in 1998 & was the first company to allow consumers to create their own protein blends. He helped create the first supplement to contain natural follistatin, invented whey protein with egg lecithin, & recently imported the world’s first 100% hydrolyzed whey.
