I have a question, about amino acids. WHat is the point of single amino acids. Like why would someone take L-Glutamin (for the immune system) or L-Cystine (Tons of benifits) alone, don't you get enough from protein powders? Or EAA's vs just taking protein.. the only 2 things I can think of is.. They require no digestion, and don't have to compete with each other.. Is that pretty much it? and how much do they really compete for each other. Does having more of ONE amino, mean it will have a greater chance of being taken up by the body?.. And if thats the case, wouldn't taking SINGLE amino acids for their health effects, be better away from protein? Anywase thanks in advance for answering this.
