I just realized that synthetic methionine is used with OptiZinc. However, L-OptiZinc uses natural methionine, but Jarrow Formulas chose mediocrity... big mistake.
Amazing how quickly it worked!

I notice my acne healed right away when I took this zinc formula. I love it!

Very good. easy to take. The copper seems to have darkened my greying eyebrows and hair. (quite a bonus at my age 69)

This has the zinc-copper balance you need. You don't want to be taking a lot of zinc without the complementary amount of copper--otherwise it throws off your mineral balance. This supplement solves the problem so you can use it to supplement your vitamins, etc. when you need extra zinc. Price is good too.
Added benifet !

Nice formulation BUT...

I purchased this product not realizing it has Magnesium Stearate in the formulation. I am searching for another zinc & copper combination that does not have this controversial ingredient.

Perfect amount of zinc

I like to take only 15Mg of zinc when I need a little extra, not 30Mg like most other companies sell. It also contains some copper to keep those levels from dropping.

My husky has a zinc deficiency, common among northern breeds, and this supplement works to clear up the skin issues he had related to his ZRD. We're happy with the effectiveness and the price.
