> Thanks Larry That is truly useful to know. And answers my main q--if it is wise to tke tyrosine and phenylalanine separately to get higher benefit.

As you said, there is evidence that GABA cannot....Oh, absolutely, supplemental tyrosine and phenylalanine cross the blood brain barrier. They are pumped in. By taking them on an empty stomach (recommended) the supplement enters the blood in high relative concentration, and can monopolize the transporter. This permits a more drug-like physiological effect than can be derived from diet, e.g. protein consumption.
