Now Foods, L-OptiZinc 30MG

Posted by free2bmoe on Jul 21, 2015

Wow. My recommended dosage has improved my allergies. About 90% improvement. I've taken over the counter and prescription antihistamine to no avail. This has improved my skins texture, and vision seems to be a bit sharper. In addition, this Zinc has helped my mother's knees. I've only taken the L-Optizinc formation. However, I do supplement with other vitamins and minerals, such as magnesium and copper at a separate time (even though this product includes copper), to avoid imbalances when high dosing zinc.

I had one bottle of this and switched to their Zinc Glycinate. Easier to swallow and no smell

Hurt my stomach

Posted by 4960512194093690807 on Jan 01, 2015

Took one capsule every day for about a week, and didn't notice anything before the last three days, then I got abnormal stomach aches, and even though I immediately stopped taking them it still hurt for about a week before it completely went away. I will still try and use them, but maybe only one capsule per month or so.

Great recovery

Posted by 4789363856603435622 on Dec 17, 2014

I highly recommend this product manufactured by Now Foods with reasonable price offered by iHerb. A single dose per day is what you need. Quick recovery from injures and is boosting your immune system.

Good for my skin

Posted by 4672103407580196186 on Oct 29, 2014

Used it for my dry skin. The chelate didn't truoble my belly. Copper used to level my problems with insuline. got no headache from it. Good for people allergic with corn. I would be even more satisfied if magnesium stearate would not be included in this product
