The problem with a lot of the hype around certain supps is actually the way the science behind their function is interpreted... the branched chain amino acids and glutamine for example both play very important roles at a cellular level in muscular growth and repair, but that doesn't necessarily mean that in all circumstances supplementing with them directly will make a lot of difference.
For example, many people add glutamine and BCAAs to whey... since whey is already about 40% BCAA and 10% glutamine on average, you'd probably gain no advantage from doing this if you were already getting enough whey.
However, taking these things at different times (like glutamine first thing in the morning on an empty stomach and the BCAAs between meals) might well give an advantage. It does depend a lot though on your overall intake of amino acids from all sources, as well as your current caloric intake as Glen suggests... that's where the problems with using studies to back up usage of these supp's come into it as in many of the studies that manufactureres use to recommend a supp they restrict dietary protein in order to get a stronger measurement of the effect of the supplement... so the studies often only show how effective that supplement would be if you didn't eat (a totally unrealistic situation!).
Most supps can be useful in certain circumstances but not in all, and the most important thing is always diet, which once right can often render a lot of supp's pretty useless.
BCAA's and L-Glutamine are not "essentials" or must-have's. A good protein powder has adequate BCAA's and glutamic acid and is an essential since most of us do not get enough protein from dietary sources.
