hey there LR glad you are hopping on the zinc wagon
personally my copper levels are fine so i haven't worried about supplementing it. as far as i know you're not supposed to take in more than 2-3 mg of copper per day and the zinc to copper ratio is supposed to be 10:1.
have you had your copper tested? i would check before supplementing...
here's a neat reference:
