Works well I will continue buying them
Size: 60 Count (Pack of 1)
This melatonin gives me a good nights sleep. I thought it was 3 mg but it is not, my mistake! I take two of these because 3 mg doesn't do it for me. I sleep like a baby when I take these and wake up feeling rested.

Incredibly Helpful for Sleep & Not Hard to Swallow w/Water or w/o
Size: 60 Count (Pack of 1)
I shouldn't be taking these due to certain medical conditions, but they taste like nothing, super effective - like I fall asleep within maybe 30-45 minutes - and I STAY asleep watch is a lot more than I can say for any other melatonin products that I've used. Again, I do have restrictions, so I only take them once in a while, but so does my roommate and he says the same. They're small enough to not be hard to swallow as well. I've recommended them to some of my friends and family and we're all in agreement. I mean, of course, consult your doctor first, but like, these have been one of the most helpful supplements for sleep which is super important to me

Good value and quality
Size: 30 Count (Pack of 1)
Excellent quality and the perfect size for my small pet to swallow. I like knowing it didn't have a lot of unnecessary chemicals and additives as well.
