Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 4.7 out of 5 by 10 reviewers.
Rated 5 out of 5 by L-OptiZinc is the best L-OptiZinc (zinc mono-L-methionine sulfate) is the best form of zinc to take in my opinion. June 3, 2014
Rated 5 out of 5 by Bioavailable Zinc This is a bioavailable form of zinc. Higher dosages of zinc will deplete copper. Many companies match 1 mg of copper to 15 mg of zinc in their vitamin/mineral supplements. May 11, 2014
Rated 5 out of 5 by A good choice I've been taking this lower dose Zinc for years and it has supported me very well. I need to take it with a meal, but other family members take it on an empty stomach and can tolerate it. Good choice! September 23, 2013
Rated 5 out of 5 by thebestzincever Began taking NOW zinc from my local health food store many, many years ago. was very pleased to find it here at Swanson.

Rated 5 out of 5 by Effective Very effective. This is the zinc/copper combination that works best for me. When I'm feeling a little rundown, I take two capsule for a couple of days. I feel it strengthens me right away. October 29, 2012
Rated 2 out of 5 by contains copper I am supposed to avoid copper, so I was unhappy to find out this contains copper. Other brands of OptiZinc do not contain copper, so I will try those. July 15, 2011
