> 1) Is it essential that you take DL-Phe or L-Tyr with absolutely no other substances? You see, I also take Diazepam in the morning and I'm wondering if it would be OK to take the DL-Phe or L-Tyr together with the Diazepam. Or will these substances interact with eachother or otherwise compete for similar enzymes and chemical pathways in my system thereby reducing the efficacy of one or the other (or both) of these substances in my body?I can't conceive of a problem with taking diazepam and amino acids together. The issue is one of not having protein in your gut so that the amino acid transporters which uptake tyrosine or phenylalanine are not busy with other aminos.
> 2) I know that to get the same dopamine effect that ideally I should approximately double the dose of DL-Phe over the amount of L-Tyr that I currently take each morning. However, I have had a look in my local health food store and a bottle of 500mg DL-Phe tablets is actually more expensive than a bottle of 500mg L-Tyr tablets.
I'm surprised to hear that.
>Therefore, taking cost considerations into account, my question therefore is would you consider that a 500mg dose of DL-Phe would be more beneficial than a 500mg dose of L-Tyr notwitstanding that less dopamine will be produced in my body, BUT because this lower dopamine production is offset by an approximately equal amount of PEA production in my body from the d-isomer in the DL-Phe? In other words will I get a better result from a higher outright dopamine concentration in my body OR will a better result be achieved with a lower concentration of dopamine acting in concert together with an approximately equal concentration of PEA in my system?
If I had to choose, I'd go with the DLPA.

> bluedogJust a thought, but maybe you might check around on the Internet. You might find prices more to your liking, and you can get your duet for the price of a solo.
