Our Members Asked:
Does taking vitamin C (1,000 mg) deplete copper in the body?
Answer:
High-dose vitamin C can potentially lower copper levels, although the effect seems to be modest, as described in the Concerns and Cautions section of the Vitamin C Supplements Review.
A better-known and established cause of copper deficiency is supplementing with high doses of zinc, as zinc competes with copper for absorption. This is why copper is added, for example, to vision supplements that contain large amounts of zinc.
