- Reviewed in Canada on December 27, 2024Verified PurchaseGreat value.
- Reviewed in Canada on October 13, 2021Verified PurchaseTaking this 50mg zinc supplement made me nauseous if I didn't take it with a full meal. I have a very strong stomach and usually don't feel nauseous from any supplement. I take a smaller 12.5-25mg dose now as part of a multivitamin and do not have the nausea issue. I think this is just too much zinc.
- Reviewed in Canada on January 13, 2022Verified PurchaseThis brand is an amazing value because no one needs 50mg of zinc per day. Just check credible sites for dosage like the National Institutes for Health in the U.S. The dosage ranges for adults from about 13 - 8mg per day, depending on the site, whether you're a man or a woman and a few other factors.
What we do with this brand is cut the pill in quarters with a razor blade. The pill holds up fine. And each of us takes 1/4 pill per day, which is 12.5mg per day. This should be more than enough for any adult, particularly considering we all get some zinc in our diets already.
That means this 250-pill bottle yields 1,000 serving. Like I said -- a great value!
