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.

Best Zinc supplement
Posted by Reviewer1884540 on Jul 29, 2014
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.

Gut & Libido
Posted by Natural-Living on Apr 29, 2014
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.
Severe stomach cramps
Posted by thesmellofsand on Feb 10, 2014
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.

still have confidence in Life extension's products. but i wish they come in smaller doses of 15mg and larger sizes of at least 150 tabs
Can't take on empty stomach
Posted by greenfern on Oct 05, 2013
Good to find a zinc monomethionine supplement with no added copper. Tried to take it first thing in the morning on an empty stomach to maximise absorption, but this lead to violent vomiting. Best taken with food!
Best for us because no copper
Posted by Reviewer2664178 on Aug 02, 2013
We are trying to boost zinc and reduce copper, and these act inversely to each other. We cannot add copper, so this is our best choice and a very good brand.
Small Capsule Size
Posted by Reviewer2060826 on Feb 02, 2013
One review from 2007 mentions the size of capsule being much larger than necessary. That's no longer the case. It's a tiny, easy-to-swallow capsule. :)

It is very good product. We take its and we give to our child (he is autist and he have a lot of allergies).
