Do you notice any difference between L-Tyrosine, L-Phenylalanine, and DL-Phenylalanine?
I read about the research behind them, have used L Tyrosine, it's ok for me, good focus for an hour or max 2 with some anxiety.
I've looked into Phenylalanine for comparison as a lot of people online swear by it as opposed to L Tyrosine for some reason (reasons weren't clear to me), and to make things more complicated, some people were swearing by L, others the DL versions..
So for people who have tried multiple or all 3, what's your experiences? How do they differ for you?
