Thanks for this thread, and chemistry lessons

I couldn't help but notice the role of phenylanaline here, and it is in those 5-hour energy drinks which give us such a boost....I've posted about it before and we have speculated here what it is that helps....I had concluded, based on the collective wisdom here, that it probably was the B vitamins in it, yet B reduces (for some reason I still dont' understand) the efficacy of sinemet, so maybe that's not it....

And if it were the B vitamins, why would the manufacturer put the phenylanaline in? What role does that ingredient play? If it has no role, it wouldn't be in there....same with tyrosine, it's in there as well...

I noticed just this past week a news article stating that the FDA wants to regulate energy drinks.
