Bests & Worsts Reviews from Amazon

Created an extreme sickly, upset stomach Even tried splitting pills in half and then in thirds; all had the same nauseously sick side effects which lasted 1.5 - 2 hours. Took product with food so that was not an issue. I imagine they are using some type of filler which is disruptive. After Re reading the label it says made in USA with select ingredients from around the world- the latter could be the problem. ( poor quality control) I’ve used Zinc many times before with no issues- but never this brand- I bought it due to the many + reviews. Something must have changed, maybe a contaminated batch. Will not purchase again, felt I needed to leave this cautionary review.
