if any were produced it would have to be a tiny amount, maybe produced by "microflora"? when you don't get dyskinesias after eating a lot of protein or surge of dopamine and when you don't develop pd like symptoms when fasting for a week one might think the amount of dopamine getting to the parts of the brain where it is needed is very tightly controlled. and think about how little dopamine one really needs on a daily basis when 24mg of requip can control symptoms for a day. and not all of that gets into the right spot in the brain.
