Which supplements support Dopamine production in the brain?

I have been treating my teen for PANDAS and related issues for over a year now. Lately, it has become clear to me that ADHD needs to be a major focus for us; I'm diving head-first into research and am wondering if anyone here can get me started, specifically talking about supplements that have helped you or someone you know. Step one will be giving her high quality green tea every morning for the L-theanine. What else?
