In reply to Free form AA's, whey, colostrum?, posted by MM on March 16, 2007, at 18:43:39
> Which is the best for getting/absorbing protein? I'm going to try an l-tryptophan supplement as well if that makes a difference (I already take taurine here and there). Are certain formulations(?) of protein more sedating/activating than others (like more or less tyrosine or whatever)? Any brand reccommendations? Thanks so much for any help with this.

Taurine is in meat, but nothing works like a couple of grams of the free form amino. I wouldn't select a protein source on the basis of its proportion of aminos, unless you're otherwise surviving on an incomplete protein source, such as corn.
I like whey protein over soy, but I really don't have a scientific argument for that.
In the interest of frugality, I'd start with the most basic (and cheapest) supplement first. Whey protein powder is really inexpensive, if you can find a source for it. It's used in commercial food production. I've obtained some from BulkFoods.com. Next up the expense list is hydrolyzed protein powder. The peptides are presumable broken down, freeing up individual aminos. Providing that is truly the case (I've never analysed a batch to be sure), uptake would proceed without requiring any digestion.
Commercial protein supps, such as you'll find at places like GNC, are way overpriced, IMHO. The flavourings and dispersants that are in there are really just for convenience. Protein powders don't taste very good. I blend the cheap stuff into chocolate soy milk, to which I also add various and sundry other supps.
I do not know the value of e.g. colostrum, or the stuff Declan mentioned. Contrary to standard wisdom, peptide fragments do indeed enter the bloodstream. I remember a study of the proteolytic enzyme bromelain (from pineapple waste), which found intact enzyme circulating in the bloodstream. This enzyme weighs something like 120,000 daltons, so it would be maybe 400 or 500 aminos strung together and twisted up? How could e.g. peanut protein cause anaphylaxis (systemic allergic reaction) if it wasn't absorbed intact? What I'm saying is that there might be something to these "special" proteins in colostrum. But they cost a lot of money.
