> Does anyone know if 40 mg of Zinc and 2 mg Copper daily is a dosage that might induce copper deficiency? Thanks...Peace...Saturn.Most people get more copper in their diet than they require. Zinc deficiency is commonplace, however.
You're probably within the safe zone, statistically. Usually, it's thought that zinc starts hogging the shared uptake pumps at intakes of 50-80 mg/day, or thereabouts. Complete inhibition of copper uptake requires even higher doses, generally in the 150 mg ballpark.
I usually recommend 30 mg Zn from supps as the UL.
