need advice on zinc tablet dosages

i have found 2 sites that sell zinc with trace copper, what would anyone suggest to these:

Zinc Gluconate 25mg
Copper Gluconate 1400mcg

or

15mg Zinc*, 0.5mg Copper

each says 1 tablet should be taken daily, however i have been told 50mg is more beneficial to our condition, taking more than one tablet wont fuck me even more??

thanks
