Very good

Posted by klinacz on Dec 26, 2014

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.

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. :)
