I’ve been reading ‘Perfect Health Diet’ by Drs. Jaminet, and have just read the portion on zinc and copper.
They suggest that copper intake should be 2-4 mg per day, and zinc 15-30 mg per day.
On lifting days, I consume about 1.8 mg copper and 16 mg zinc. Non-lifting days: 3 mg copper, 28 mg zinc. I take Elitepro Minerals each day, so add 30 mg zinc.
Zinc and copper form the essential antioxidant superoxide dismutase, and studies show that zinc-copper balance are very important. In fact, they state “But high doses of zinc, such as 40 mg per day, are positively dangerous.”
“At 10 mg per day of zinc, 1.1 mg per day of copper are sufficient to achieve balance, but at 15 mg of zinc, 1.35 mg of copper are needed, and at 20 mg of zinc, 1.6 mg of copper are required.”
My concern is I may be taking in too much zinc, as I don’t supplement with copper and don’t eat any beef liver. Any thoughts?
FYI you can google Perfect Health Diet and find their diet / supplement recommendations, along with the studies.
