First thing, just to be clear: <a href="">tyrosine</a> and <a href="">tyramine</a> are two different things.

Tyrosine is present in a ton of foods -- poultry, fish, peanuts, almonds, avocados, dairy, lima beans, pumpkin seeds, sesame seeds, bananas, and soy products. It can also be synthesized in the body from phenylalanine, which is found in soy, egg whites, dairy, nuts & seeds, and meat & fish. Between these two things, tyrosine deficiency is almost unheard of, so I doubt supplements would have much effect.

Tyrosine is used by the body to make L-DOPA, which in turn is used to make the neurotransmitters dopamine, norepinephrine, and epinephrine. You need the enzyme <a href="">tyrosine hydroxylase</a> to turn tyrosine into L-DOPA, but in the rare case that you don't produce enough of that enzyme, you get <a href="">a very different disorder from ADHD</a> -- one that looks a lot like Parkinson's. And if you have enough of the enzyme, and enough tyrosine, adding more isn't going to convert it into greater amounts of neurotransmitters. The conversion reactions are self-limiting; your body quits making more when it thinks it has enough.

If you want to get more tyrosine, I'd recommend eating more cheese over paying for supplements. :)

One more thing: here's a link to several huge, detailed blog posts that discuss tyrosine, its metabolism and effects in gory detail:
