Best Jetlag saver!
I never had insomnia or sleep related issues and I never took melatonin on regular basis but what I always found is I get severe jetlag when I travel across opposite timezones! I tried this and it is actually the best solution for the jetlag problems if you want to get rid of that tiring jetlag faster.. I took it in the night time there and within 20 minutes, I was deep asleep and woke up at 6 am with all satisfactory and refreshing sleep.!! Highly recommended

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.

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.

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.

Sixty percent of the time it works every time :) I think it was MIT that did a study showing 0.3 mg or 3mcg is optimal dosage. That's why I got this, and it's hard to find in stores. I take this 1-2x/week, around 1.5-2 hrs before bedtime and 12 hours before I want to get up. I feel sleepy at the right time, and alert when I wake up (not groggy). So happy with this product. Melatonin is a powerful antioxidant, and some doctors at the frontlines of coronavirus/covid recommend taking melatonin as part of temporary, whole treatment plan under supervised care. I also have melatonin in 12mg (super duper high dose) for when I get a viral infection for this reason. The last virus I contracted lasted only 4 days, taking safe amounts of vitamin c (6-9g/day) and melatonin (6-9mg/day) for the duration. I also took elderberry and zinc. So I use the 0.3mg bottle when I'm feeling a little run-down and need an immune boost and deep sleep, and it works great!
