Product Overview


  • For Longer Life
  • Superior High Potency Zinc
  • A Dietary Supplement

Zinc is a mineral that stimulates the activity of approximately 300 enzymes, which are substances that promote biochemical reactions in your body. These reactions are essential for the formation of superoxide dismutase, one of the body’s most important free radical scavengers. Zinc also promotes immune function, taste sensitivity, protein and DNA synthesis, insulin production, reproductive organ development and sperm motility. Zinc also supports normal growth and development during pregnancy, childhood, and adolescence.

Maintaining adequate levels of zinc is equally important to aging adults. As people grow older, their immune function declines, partly due to the decreasing size and function of the thymus gland. Evidence suggests that zinc may help to maintain healthy function of the thymus gland in elderly people. Scientists have also found evidence that a zinc deficiency in elderly adults may contribute to impaired immune function with aging, or immunosenescence. These findings suggest that zinc plays a critical role in supporting healthy immune function with age.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Take one (1) capsule, one to three times daily with or without food, or as recommended by a healthcare practitioner. The number of capsules you take will depend on the amount of zinc in other products you are taking. Most people's intake of zinc should not exceed 90 mg a day.

Other Ingredients

Rice flour, vegetable cellulose (capsule), silica, vegetable stearate.


Store tightly closed in a cool, dry place.

Caution: Supplemental zinc can inhibit the absorption and availability of copper. If more than 50 mg of supplemental zinc is taken daily, 2 mg of supplemental copper should also be taken to prevent deficiency. Chronic ingestion of more than 100 mg of zinc daily may be toxic.

  • Do not exceed recommended dose.

iHerb Customer Reviews

Very good

Great product, maybe it lacks a little bit of copper, but still very good. The only disadvantage is that it is not L-OptiZinc form.

Thanks for your feedback!

Best Zinc supplement

Posted by iHerb Customer on Jul 29, 2014 | Verified Purchase

Why have you discontinued this?? It is the best zinc supplement I've used and one that does not contain Copper. Will need to look for another supplier.

Thanks for your feedback!

Gut & Libido

Posted by Natural-Living on Apr 29, 2014 | Verified Purchase

Great product for Gut health & to increase Libido. Start slow if you experience loose stools. I had some detox symptoms at the begining. Urine was smelly, a sign of expelling heavy metals/toxins.

Thanks for your feedback!

Severe stomach cramps

Posted by thesmellofsand on Feb 10, 2014 | Verified Purchase

Having never taken Zinc before, yet having had good experience with LEF products, I decided to try OptiZinc. Unfortunately, roughly half an hour after taking a single capsule I became bedridden with severe stomach cramps for several hours. I won't be using the product again.

Thanks for your feedback!
