Study shows high amount of zinc 2+ ion can cause optic nerve damage (i.e. color less vivid, less contrast, dimmer vision). Does zinc carnosine dissociates to form zinc 2+ ion that can cause overdose? Do you experience any vision problem after taking zinc carnosine with recommended dosage?

Best Answer
I have been using this product daily for years now (8+) and have never experienced anything with optic nerve damage. The few times I forget to take a dose for a few days (ie - travelling), I find my symptoms of stomach pain return. I totally stand behind this product.
