I only ever bothered with a B-complex, Tyrosine, and 5-htp as recommendations from the Mood Cure. The rest is really stuff you can get in a multi. Except maybe Magnesium? I forget. Anyway, I hope you figure out what works for you!
FYI, I went off 5-HTP for a bit last summer. Felt good. Might've backed off on the Tyrosine too. When my gut problems started in August (chronic constipation), my mood plummeted and I had to go back on. Since then, I've had to stay strict primal, and then paleo, because I'm now intolerant to dairy. I've felt so much better since then and am starting to back off on the 5-HTP. Striving for good health can only help your brain!
Have an awesome day!
