## Overview

NOW Foods Melatonin 5 mg Sustained Release tablets deliver a gradual 4-hour release of melatonin, supporting natural sleep cycles, immune function, and gastrointestinal health. Vegan and allergen-free, this GMP-certified supplement offers 120 tablets per bottle, combining trusted quality with holistic wellness benefits for adults seeking effective, clean sleep support.

## Description

Gastrointestinal Support* Melatonin is a potent free radical scavenger naturally produced in the pineal gland and present in high amounts in the gastrointestinal tract.* It is involved in many of the body, brain and glandular biological functions including regulation of normal sleep/wake cycles, regulation of the immune system and maintenance of a healthy gastrointestinal lining.* NOW® Melatonin Sustained Release Tablets allow for steady release and more gradual, sustained utilization. This sustained release tablet is formulated to release over a 4-hour period. Natural color variation may occur in this product.

Review: Tiny, effective, good price! - This does the trick for me. One tiny pill (plus some magnesium glycinate) before bed and I sleep well. I take this 45-60 minutes before I want to go to sleep; that seems to be the sweet spot for me. No side effects, no “sleeping pill” hangover. The price is really good, especially for the sustained release kind. If you want to give melatonin a try, I recommend this.
Review: Need some help getting to sleep - Great Brand and Sustained Release helps with sleep at night
