## Description

21st Century Melatonin 10 Mg Prolonged Release, 120 Count

Review: Great sleep - This melatonin really works, it is the best one I have found, I will keep buying this, very impressed how good it works
Review: As Expected. - Work very well but these seem to be stronger than others rated at the same strength (10mg). I find that cutting them in half gives me a good sleep cycle. Taking the whole pill leaves me with a hangover. I have to think that these are accurately described and other melatonin tablets are just under strength. Also, they work all night. Other melatonin I've taken (even those described as slow release) leave me awake half way through the night.

## Features

- The information below is per-pack only
- SLEEP THROUGH THE NIGHT: This 10 mg extra-strength melatonin uses a prolonged-release design to help adults with occasional sleeplessness fall asleep and stay asleep, so you wake feeling genuinely rested.*
- SUSTAINED RELEASE, NOT A SINGLE HIT: Instead of releasing all at once, the tablet delivers melatonin gradually through the night, supporting steadier, more continuous sleep for people who tend to wake at 3 a.m.
- NO DEPENDENCY: Non-habit-forming and drug-free, it works with your body's natural rhythm so you can use it occasionally without worrying about reliance.
- FOR RESTLESS SLEEPERS AND BUSY MINDS: Designed for adults who fall asleep fine but wake through the night, plus travelers and irregular schedules, one tablet 30 minutes before bed.*
- 120 TABLETS, TRUSTED FOR 34+ YEARS: Four months of restful nights, gluten free, non-GMO, and made in the USA from domestic and globally sourced ingredients in an FDA-registered facility and quality-tested for label-accurate potency.

### ⭐⭐⭐⭐⭐ Great sleep

### ⭐⭐⭐⭐⭐ As Expected.

### ⭐⭐⭐⭐⭐ For me, this works better than others I've tried.
*by J***R on July 30, 2026*

The first Melatonin supplement I've tried that actually worked for me. Everyone has different results with different supplements, but this one worked best for me. It seems to be partially instant release, and partially timed release? I am not sure if that is true, but that is how it seems to work for me.
