Hi Healthgirl
If you are getting too much zinc (either through diet and/or supplementation) this can cause your copper levels to drop. The important test number is the zinc:copper ratio. It should be a ratio of around 0.7:1.0
Watch for hidden zinc in other supplements eg: multivitamins, combo supplements etc. The tolerable upper intake of zinc recommended by the NIH for an adult is 40mg of Elemental Zinc daily. Taking excess zinc over a long period can cause toxicity. Elemental zinc is the amount of actual zinc mineral in a compound eg zinc sulphate (many supplements only list the compounded amount so may not reflect the actual amount of Elemental Zinc.)
Sorry if this isn't very clear. Here's a link to the NIH website that has more info. You may also find other info about low copper by searching the site:

Hope this helps and you get some answers soon.
