>Being that the price difference is huge when you are taking high doses (and buying in bulk), my question is, does the b6 and C really make that much of a difference in absorption of Tyrosine?
Well, that is beside the point. What matters is that our genetically controlled enzymes have prerecorded instructions on how much tyrosine to convert to this and that. Any extra is discarded or converted to other substances.
You don't see many success stories of 5htp or tyrosine. Once in a while on the net, or in a book some doctor wrote claiming it works on their patients (but reading the fine print says if it is more than mild depression you should see a doctor for medication).
People get short-term blips of improvement, or deterioration, from these isolated substances. Probably the most reliable thing is that 5htp can usually be counted on for deep sleep with vivid dreams.
Both have not had good clinican testing. In the ones that were done, way back in 1980's, both substances failed to improve even a single patient.
But, in a couple of those 1980s studies, the one supplement that did show some surprising results was DL-Phenylalanine. Might want to consider that one instead of tyrosine. Regardless, keep in mind, your body will limit how much it uses for the desired goal you have in mind.
All this of course assumes that the theory of low brain chemicals is accurate. It doesn't even touch on other topics such as receptor sensitivity, receptor damage, receptor density, other hidden as-of-yet undiagnosed conditions.
