Good.
These work really well. Price is great. My kids have not complained about the taste or any issues with chewing them. No sleep issues or grogginess upon waking.

Great product. Works well and tastes good too!
I purchased this melatonin for my five year old. Not only is she a terrible sleeper she’s extremely particular about how things taste. This product works wonderfully, and tastes great too! It works quickly to help my child fall asleep, within 10 minutes, and now they are able to sleep through the night without any issues. I highly recommend this product for parents looking for a natural way to help their child sleep better.

Wouldn’t buy again
We got these to help our 6-year-old fall asleep. We were looking for something that was yummy and worked for sleep; these didn’t do either. My son didn’t like the taste and when he did finally take it, he didn’t fall asleep.  We never took it again.

My children occasionally need a really good nights rest.
Sometimes my kids need a good night's rest and this is my go-to product for that! The raspberry flavor makes it easy for them to take as well.
