Irishbookfairy hard to say about the serotonin. Everyone is different. I would say if you are eating enough protein everyday then you should be fine.
I’ve read Serotonin is pretty much a downer for people with ADHD because it lowers L-Tyrosine (found in meat) supplies. The L-Tyrosine is there to be converted to dopamine, and the Adderall helps the dopamine receptors scoop up the dopamine better. Or something like that. 
I have tried 5-ht which is a dietary supplement for serotonin, but it made me feel much more run down. It also made my autoimmune disorders worse. I then looked it up and it is recommended for people with health problems like mine to stay away from 5-ht and a lot of SSRI’s.
