Tabs work 100 per cent
Product worked well for my system. A bit too well. I took a whole tab the first night and l was out before planned. Too 1/4 tab the second time and it felt more natural.

Amazon Melatonin? Amazing!
These work as well or better than some of the more expensive ones my wife usually gets. They don't dissolve in your mouth and they arent gummies. No extra sugars involved. Puts me to sleep quite well and allows me to stay asleep. No bad taste, no weird dreams. No side effects. Absolute gem of a find on Amazon. Great price for a great night sleep.
