Time release.. ONLY way to go
Used this brand before... when refill needed, came back for more. Time release is the best way to go as it works all night.
Not one big hit when you 1st go to sleep... A nice "hit"... to get you to sleep and then a slow release of the rest, to KEEP you asleep...
Don't think you'll be disappointed. I use sustained release with any vitamin/supplement I take (assuming the company makes it) .. including this. It's the best way to allow your body to utilize the product.

A subtle sleep enhancer.
Melatonin, in my experience, is a very subtle drug. I took it for about a month and then stopped before I actually saw what it was doing. It allowed me to fall asleep quicker and when I woke up during the night, to fall back asleep quicker as well. No more tossing and turning. I prefer the timed release version since I tend to sleep about 4-5 hours straight and then wake up sporadically after that. I had been buying the timed release from GNC but this brand is much cheaper, more pills, and just as effective. I've also tried popping another one after that initial 4-5 stretch of sleep to further prolong sleepy time, but I don't know how effective that is. It doesn't put you to sleep, so there's no grogginess when you wake up. It just jump starts the natural process.

Time release is the best way
I like these time released tablets. Time release is surprisingly hard to find unlike the immediate release style tablets. Time release allows for a longer sleep pattern as it enters the blood stream slowly over time allowing it to stay in you system. Immediate release will hit you hard and fast but your body will metabolize within a couple of hrs leaving you without the melatonin in you system. I took off a star for being pricey, but these do work very well.
