Great product
They work great since my daughter won't take the gummy melatonin anymore.

Perfect for low dose, great price
On my second bottle, great product for the cheap price, lasts almost a year. Hard to find in this low dose. I personally find low dose melatonin to work better than the higher amounts. It’s the sweet spot.

Knocks me out cold
I wish I could easily find a lower dose, but this works.
Take one about 30 mins before I want to sleep and when I fall asleep I don't wake up in the middle of the night. I normally have insomnia but one of these generally gives me 9 hours of sleep.
It doesn't ALWAYS work (I have health problems that can keep me awake) but instead of 5-7 hours sleep I am consistently getting around 9.
The only problem is I'm groggy in the morning. But I feel a lot less haggard and anxious in the morning now so I think I'll be continuing with this.
