Works Well

Posted by iHerb Customer on April 17 2018 | Verified Purchase

I bought these for my mother as she was having a terrible time with restless leg syndrome and was up a lot during the night. These melatonin have helped her get her rest and reduced her episodes. She isn't groggy in the morning and wakes refreshed. She's on her second bottle and swears by them.

Thanks for your feedback!

The tablets in double dose has a very good effect on my daughters sleep! And no side-effects.

Product OK but less than 120 tablets

Posted by iHerb Customer on March 28 2018 | Verified Purchase

Received my two orders of this melatonin today and counted out the tablets - 119 in one and 115 plus some fragments and dust in the other package. The packaging could be way smaller, too.

Thanks for your feedback!
