Good enough
I like that this is very low and I do well with the low count and do not wake up groggy

Works well
This works well to help go to sleep and one doesn’t feel drowsy upon waking up. Very natural.

The perfect dose!
This works so well at 2 things: 1) increasing my sleep drive close to bedtime (helping me fall asleep faster / decreasing latency) 2) not causing me to wake up halfway through the night like higher doses of melatonin do. Perfect dosage level. Pair it with L Theanine (100mg) and Phosphatidylserine (100mg) 1hr before bed and you'll boost your sleep drive and sleep better while avoiding reducing CNS activity (that may otherwise lead to greater snoring/apnea episodes in many people) as seen in some supplements like Kava or Valerian.

Does the job, but may cause extremely vivid dreams...
I took one of these pills before my nightly shower. After getting into bed, I was asleep in record time. Roughly 15 minutes after getting into bed, according to my smartwatch. A dramatic improvement over the 2 hours that it normally takes me. But throughout the night, I experienced VIVID dreams. Nearly life-like. It started off with a nightmare where I was beating people up for no reason..? It got so intense that I woke up in the middle of the night, but then promptly fell back asleep upon realizing that it was just a dream. After falling asleep, I promptly slipped back into the land of dreams, where I had a much more pleasant dream; cuddling with a classmate. I woke up that morning in a state of bliss. Anyways, this product really does the job. It helped me to get my sleep schedule back on track, and I had some... Interesting dreams, in the process. Highly recommend, especially if you're a lucid dreamer.

300mcg doesn't work on me
I tried 300mcg and it doesn't work on me. Then i tried 600 mcg(two pills) and it worked a little bit. So i guess optimal for me is around from 800mcg to 1,5 mg.

Works for me, (lifetime insomniac)
I have tried it all. I’ve used Valerian root. I’ve used prescription stuff, (which gave me horrible nightmares and cottonmouth, among other side effects.) I’ve used OTC supplements. I’ve even used melatonin that is higher dose. When I was told about this, I was super skeptical. That was about three years ago, and numerous orders ago. I gave this an honest shot, and it seems to have set my circadian rhythm just right. I take it around 7pm or so, and I fall asleep pretty easily and peacefully around 11 or earlier. If I want to stay up later, I usually can. This has just been a godsend. I also usually stay asleep too. And THAT is a huge part of why I like it. I’m not groggy in the morning and I wake up pretty early usually. This stuff works for me. I did have to give it time though. I think a few weeks of using it would do the trick.

The best dose!
The best melatonin I have ever used. Improves my deep sleep, doesn't leave me feeling groggy in the morning. I've tried 3mg and 5mg and this dose is far far better.

Just right
Higher doses left me cold and groggy during the day. Still sleep like a baby with these, with no side effects.
