Premier Research LabsLiquid Zinc Ultra: Liquid Zinc Supplement - for Immune Support & Well-Being for Adults & Kids - Highly Absorbable Drops - Used for Rapid Analysis of Zinc Status - 8 fl oz

I was surprised with the quality of this product, without a doubt the best money invested, the opinions of other buyers influence which is the best option, without a doubt it is this, five stars.

Being it liquid makes it much easier to take. I am so tired of most supplements being in a pill form that this is a nice change.

I noticed a review of someone who was frustrated that they wasted so much product trying to pour it into their teaspoon. There’s such an obvious fix here that made me snicker that I’m sure most of already realized, but just in case or for that one, user all you need to do is get a simple utility knife and carefully insert into the foil seal at the top of the bottle, therefore making a very small slit in the seal, instead of just tearing the seal off altogether then, as you pour the liquid out, it is only going to come out of a small slit, and it will come out very gently and slowly and simply make the slide to the size that works best for you based on how accurately you’re able to pour liquid into a teaspoon lol sometimes the best fix is the easiest one, and sometimes also overlooked. Cheers. In good health ☺️

This bottle came with the inner seal, but no cap on top of it so when I opened it, there was no way to close it back up. I had some little bottles that I had purchased for something else so I just filled those with it. It tastes like horrible death, but that’s because there’s no additives or sweetener. I may try adding my own xylitol or something because it tastes so so bad it’s going to be hard to take every day.

Absolutely no complaints.I am always cautious about what is on the bottle being what is inside, and I have used Zinc tally in various forms for over a decade. My feedback isn't the same as a test by a lab, but I can say this passed my personal test as being excellent quality.

I just tested my zinc with this. Its great if your going to takeIf just testing maybe look for smaller bottle.

This stuff is just great, but not used how you might think. From the research, "topical applications of zinc sulfate heptahydrate can facilitate the transdermal absorption of zinc, which can be particularly beneficial in therapeutic contexts such as promoting skin healing and potentially delivering zinc where deficiencies exist."I have found that it is better than eating oysters when applied where needed. A definitive T-booster and it dries quickly and is not sticky. Apply with caution as it also ups the libido.

I've used this product before and am happy with it. The problem is with the person who packed the box. The bottle arrived without a lid and the lid is indented. As far as I can tell, it is not leaking. I am hoping that it is not pierced. I have it upside down on a dry tissue to see if any liquid escapes the bottle. This is annoying. Luckily I have a stopper I can use to close it. Gotta have more pride in your work.
