Zinc & copper

[Cash]

I heard that zinc supplements should be taken with copper because zinc lower copper levels, some say this only applies to large doses of zinc, others say this applies always.

What's the deal? I'm on 10mg picolinate, should this still apply?

It is believed that zinc and copper compete for absorption in the digestive tract so that a diet that is excessive in one of these minerals may result in a deficiency in the other. The RDA for copper in normal healthy adults is 0.9 mg/day.

Found what i was looking for, thanks for the link anyway.

Zinc and copper are needed in a 10 to 1 mg ratio for proper absorption and for the maintenance of the human body.
