amino acids

does your body make its own amino acids??

Yes. There are two classifications of amino acids: essential and non-essential. The body can synthesize the non-essential amino acids (i.e. alanine, arginine*, asparagine, aspartic acid, cyctine*, glutamic acid, glutamine*, glycine*, proline*, serine, and tyrosine*) from the other amino acids that are consumed in the diet. The ESSENTIAL amino acids (i.e. histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine), however, canNOT be made by the body, and MUST be consumed through either diet or supplementation (Wardlaw & Hampl, 2007).

* These amino acids are also classed as 'semi-essential', because they are synthesized from ESSENTIAL amino acids (Wardlaw & Hampl, 2007).
 
okay my dad was tellin me that all the "crap" i take (amino acids) is bad, and that if i keep taking them my body will stop "producing" them

Nice post!
The body can produce all the none essential amino acids from the essential amino acids.

They are also regarded as "semi-essential" because, under certain circumstances such as injury (tissue catabolism, bone damage/remodelling, leaky gut, and so on) or during growth processes, these otherwise non-essential amino acids become more or less essential.

your not alone, i get **** from the guys at work about protein shakes and my purple wrath now i tell them its cordial
 
It's best not to listen to anyone who isn't familiar with supps. According to my dad my protein shakes are going to make me fat, and he is 40 pounds overweight.

My mom is convinced that creatine is a steroid.

Your body WON'T stop producing AA, regardless of supplementation. I wouldn't listen to your dad, then, when it comes to this, if he is not familiar with nutrition, physiology, etc.

Dead on. People assume far too much, and critisize anything that is unfamiliar or strange to them. Just because you're taking a heap of pills, etc. does not make you unhealthy or any likely to die any earlier or so forth. The best thing to do would be to EDUCATE them on WHY you use said products if they continue going on about it. Otherwise, ignore them or tell them to be quiet.

I talked with layne about this awhile ago, esp since its not in Xtend, he had a pretty solid reason for it, but I moved passed it once he explained it. I'll try to dig up some info

thanx!
looking forward to reading the logic.
ive heard people discuss the psychological/safety issues of too much tryptophan... however from a anabolic/metabolic standpoint i am curious to know- becauce tryptophan is a rate limiting AA when it comes to protein synthesis.
 
The evidence I've found so far relates to the tryptophan/bcaa ratio, and most sites say to supplement bcaa's to limit the amount of tryptophan that is streaming through your body. Most evidence supports that during exercise free tryptophan begins to rise in your system crossing the blood brain barrier and induces fatigue. At this point I don't see a need to supplement it pre-workout, but nothing against it post-workout.
 
However Leucine inhibits the metabolism of tryptophan. In many cases where folks use Leucine and experience depression- this is usually the problem...

Using EAAs (with tryptophan) however would be ideal postworkout for recovery. I agree preWO one may run into fatigue issues.
