I'm not sure if they're still available or not but when my son was around that age (10 yrs ago) I tried him on these natural chewable tablets called "Calm Kids" they were basically made from dried Apricots. They worked like magic and then didn't need all the medications the doctors were pushing (tried to say he was addhd??) they took about a week to take action but he was like a completely different child once they 'kicked in'.
