DL-Phenylalanine — Is It Excitatory?

[DebInAustralia]

Hello all,

I want to supplement with 5HTP as I suffer with anxiety/ocd/depression that has worsened significantly since the onset of my tinnitus 2 years ago.

However, I noticed it contains DL-phenylalanine. Is this excitatory? I am concerned about the effect this might have on my tinnitus.

thanks
