> And generally Phenylalanaline is better than some of the others. Why? Well because it's one step away from L-DOPA which is one step away from dopamine L-Phenylalanine is first converted to L-Tyrosine, which is then converted to L-DOPA, which is then converted to Dopamine. However, it's very misleading to reduce the body to basic formulas like this because these pathways from dietary amino acids to neurotransmitters are all regulated within the body at many different stages, so adding a little extra Phenylalanine to a meal isn't going to give you a dopamine boost. You consume a lot of Tyrosine in a standard protein like chicken breast (multiple grams, potentially) and nobody is getting high off of standard protein. The body is very good at regulating these things.
