    Do not buy this brand. Impossible to swallow. You take a big gulp of water, swallow and the next thing you know, it’s still in your mouth sticking to the back of your tongue. For some reason, this pill does not want to go down your throat. I am going to buy a different brand in gel caps. Never have problem with this form. If you’re going to buy zinc, buy in gel caps. Easier to swallow.

    These are the best zinc pills I have found. I have struggled with hormonal acne my whole life. I break out in pimples, white heads, black heads, cysts, you name it, it’s on my face. I was recommended zinc to take to try and combat these problems. I know Zinc is going to complete cure my acne but I have definitely noticed a big difference since I started taking them! These pills are actually a bit smaller than my other supplements, so they are definitely easy to swallow. Just make sure you don’t let the pill sit on your tongue too long. The coating has an awful taste to it.

    They made a small difference for me; I was taking them for clearer skin bc I’ve had problems all my life. It’s not a miracle cure or anything, but even a slight difference is better than nothing. The price is pretty good too. The only downside to these is that you absolutely HAVE to take them on a full stomach because if you don’t, they will make you extremely nauseous. TRUST ME ON THIS: save yourself an hour of nausea rivaling morning sickness and please just eat some food with these lol. (Splitting them in half and taking them at different times helps with this too).

    Pretty much was choking every other time I tried taking these, even with water at the ready, not a pleasant experience. Threw out the bottle.

    Great for gut health, immunity, and skin. I take half a pill at a time on an empty stomach. Twice a day if I’m around sick people, or having acute issues that could be benefited from more zinc. 50 mg per day is too much for most people to take regularly though, and can cause copper imbalance or even overdose. Best to get tested before taking this for months on end, or at the very least do a lot of research first.

    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.

    I bought this for my husband to aid in blood sugar control because he is a type 2 diabetic. We have since taken him off three daily doses of two different prescription medications. This stuff works wonders.
