They do work but they taste terrible!
Size: 60 Count (Pack of 1), Style: Melatonin 5mg
I got these for my special needs son after his doctor recommend trying melatonin to help with some sleep disturbances. They definitely help him go to bed calmly and even stay in bed through the night but I have to bribe him to get him to take them because the taste is so bad!

Excellent Product!
Added this to my evening Magnesium Glycinate about 2 or 3 weeks ago. My difficulty getting a full nights sleep gradually started to improve. I am now averaging 7 or more hours straight, up from 2.5 - 3hrs. Waking feeling refreshed and more alert, not tired and groggy now. No more mid morning slump. Just keeps getting better... it's not instant but, continues to improve. These improvements alone are well worth the cost.
Also, seems to have added an extra kick to the other reason I take Magnesium... my hip pain and lack of flexibility has also improved. Almost no pain now and flexibility has gone from zero to at least 50% now. I can bend at the hip now and look forward to being able to put on socks, tie shoe laces, scrub feet and trim toenails without assistance!
I have always been physically active until the years of unconsciously favoring my left leg after breaking my right leg in several places ...twice when I was younger began to take a toll on my flexibility. Starting gradually in my mid sixties until now at 68, the list of immobility problems had become very annoying. So, this improvement is is most exciting!
My thanks to Teraputics Pure Life for making an excellent product!

Great Product
I purchased "Magnesium L Threonate, Magtein™, Brain Supplement for Memory, Focus, Sleep and Cognitive Support". I added this to my evening regimen and my difficulty getting a full nights sleep gradually started to improve. I am waking up feeling refreshed now. No more mid morning slump. These improvements alone are well worth the cost.
This improvement is is most exciting! My thanks to Teraputics Pure Life for making an excellent product!

It Put Me On An Even Plane.
After 2 months of using this supplement my sleep has improved immensely. I wake up refreshed and recharged Jitters have subsided. And bathroom trips are on a schedule.
