Branch Chain Amino Acids

I was thinking of taking BCAA's along with my diet as they appear as a staple in most weight training diets...until I found this:

Some research has shown that BCAA supplementation (typically 10-20 grams per day) does not result in meaningful changes in body composition, nor does it improve exercise performance or enhance the effects of physical training. However, BCAA supplementation may be useful in special situations, such as preventing muscle loss at high altitudes and prolonging endurance performance in the heat. Studies by one group of researchers suggest that BCAA supplementation may also improve exercise-induced declines in some aspects of mental functioning.

Has anyone got any input to make on this?
 
There is no point in supplementing with pure BCAAs.. just take a regular protein supplement (if you don't get enough from your diet, or just to get some protein + carbs in quickly and easily after your workout), it contains BCAA and is A LOT cheaper.
 
no need to supplement with any amino acids, as you get amino acids from the protein supplement and from your daily diet.
 
Thanks Karyk, save me some cash
