How It Helps

Cooper Complete® OptiZinc Zinc Supplement contains 30 mg Zinc as OptiZinc®, which is in the methionine form for better absorption. Zinc is an essential mineral necessary for good health. The body uses zinc for DNA and protein production. Zinc helps the immune system fight off viruses and bacterial infections.

While oysters provide high levels of zinc, other shellfish, beef, pork and poultry all contain zinc. Whole grains, beans and nuts and seeds also contain zinc but at lower levels than animal sources. Packaged breakfast cereals and meal replacement bars are often fortified with zinc. Mild zinc deficiency is fairly common.

Each bottle of OptiZinc supplement contains 90 vegetarian capsules. Daily recommended serving is one capsule or as recommended by your physician.

All Cooper Complete multivitamins contain 15 mg zinc. This supplement is an option for individuals who have been advised by their physician that they need additional zinc supplementation.

6 Questions
Ask a Question

What zinc medication interactions should I be aware of?


Zinc supplements reduce the effectiveness and absorption of both zinc and antibiotics. To minimize the effect, take the antibiotic at least two hours before, or four-six hours after the zinc supplement.

Zinc supplements also lower the absorption of the medication penicillamine (used to treat rheumatoid arthritis). To minimize the effect, this zinc supplement should be taken at least two hours before or after taking penicillamine.

Thiazide diuretics (such as hydrochlorothiazide) can increase the amount of zinc lost through urination.


I’ve heard zinc supplements can help reduce stinky foot odors. Is this true?


There is anecdotal evidence that 50- 100 mg zinc supplements daily may reduce foot odor.


Should I take this product if I am also taking Coumadin or Warfarin?


If you are taking Coumadin or Warfarin, we recommend consulting your doctor before adding any supplements to your diet.


Can too much zinc be harmful?


Yes. Taking too much zinc long-term can cause serious health problems as copper levels are decreased. This can suppress the immune system and also cause heart problems and anemia. For this reason, we do not recommend taking more than one (1) zinc capsule per day. HDL cholesterol level may lessen if too much zinc is taken long term.


How much zinc is in the Cooper Complete multivitamin I take?


Cooper Complete Original and Cooper Complete Basic One multivitamins and mineral formulations contain 15 mg of zinc. Cooper Complete Gummy Multivitamin does not contain zinc.


Should I take OptiZinc Zinc Supplement 30 mg with or without food?


Zinc supplements are best absorbed when taken on an empty stomach. If possible, take OptiZinc Supplement at least one hour before, or two hours after, food. If you are taking OptiZinc Supplement with food, be aware that high-fiber foods can interfere with zinc absorption.
