An absolute must for vitamin D. Before finding Zarbees, I tried the d-vi-sol and the Ddrops. The d-vi-sol solution was hard to give to an exclusively breastfed baby that rejects anything but the boob. The serving size was too big- it took 4 squirts to get my kids to swallow without choking on it all (not to mention the awful smell). I really wanted to like the Ddrops, but the serving size was too small. The baby has to get on the boob on cue- not always an easy feat. It was hard to tell if the drop made it in the baby's mouth, then I was too afraid to give another drop, because that would effectively DOUBLE to amount I gave him.... and I didn't want to give too much...

But Zarbees has the PERFECT amount to be able to squirt in my baby's mouth without it causing him to choke. It was like Goldilocks and the 3 bears- the other two supplements I tried were too much or too little, but Zarbees was JUST RIGHT.

My only complaint, to which I wish Zarbees would listen, is that the last box I bought, there was no extra dropper included! The dropper they gave was the one in the lid. Now, if you read the directions, after you give the baby the supplement, you are supposed to rinse out the dropper. I do like to do this, rather than contaminate the bottle.... but the dropper IS the lid! How am I supposed to wash it out good enough and dry it and put it back in... meanwhile there is no lid on the container.

How I solved the problem: luckily, I had saved the original dropper than came with the first box of Zarbees I used. The dropper is much easier to clean and use overall.

To Zarbees: Please include the skinny little plastic syringe dropper in the box again!

First arrived with seal broken & content leaked. Returned it. Replacement came looking like the seal had been glued as the "lift tab" part was unable to be pulled up & sticky clear'ish glue kept coming off on my fingers. The content was extra liquify & oddly colored (unlike what we've purchased in retail stores). Maybe a problem with extreme temperatures in warehouses/shipping?? Not sure, but I will not be purchasing this type of product from here again.

I've bought this product before in stores, and it came with a very clearly marked syringe for proper dosage. This bottle came with a dropper with no markings on it whatsoever. I will not purchase again. Vitamin D can be toxic and dangerous to infants if given too much. This packaging is a clear life threatening issue.

Received it today and sending it back. Has weird chunks of stuff floating in the liquid. It must not have been stored properly. I like this brand normally and have had no issues so it must be the seller here on Amazon.

Unfortunately the dropper attached had no markings for dosage at all. I tried going through all the other droppers I have for various infant medicines and vitamins and none had a dosage for what this required (I believe .25) completely useless. I opened the package about a week before I actually used it, and realized I couldn't remember if the dropper was packaged separately and if the tamper evident seal was on it. Then I was worried that maybe someone had previously opened this and changed out the dropper.. sounds crazy but why else would there be NO markings?? Ended up just throwing away and replacing at the drug store. Won't be buying online again (there goes my convenience factor)
