Review: 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
Review: Its what you want if you want Melatonin - This is the right dose; low and physiologic; only company that makes this size; good for them; bought many times.

### ⭐⭐⭐⭐⭐ Best Jetlag saver!
*by A***T on August 1, 2025*

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!

### ⭐⭐⭐⭐⭐ Its what you want if you want Melatonin
*by P***R on February 1, 2026*

This is the right dose; low and physiologic; only company that makes this size; good for them; bought many times.

### ⭐⭐⭐⭐⭐ The perfect dose!
*by C***S on August 28, 2025*

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.
