Melatonin-SR is gradually released into the bloodstream
to help you fall asleep and stay asleep.*

31 reviews


When it comes to living a healthy life, getting enough sleep matters. Many of us who have trouble falling asleep and staying asleep turn to Melatonin products for help. Melatonin, a hormone that regulates the sleep-wake cycle, is probably the most researched natural remedy for occasional sleeplessness.* Researchers agree: it works. There’s just one problem. Melatonin is quickly metabolized, so it leaves the body within four hours. This means that while it’s extremely effective for those who have trouble falling asleep, it doesn’t do much for those who wake during the night or early in the morning.
Melatonin-SR is the first product to provide melatonin in a special micronized, sustained-release matrix using patent-pending MicroActive® technology to help you fall asleep and stay asleep. 
Melatonin-SR has been shown to:
  • Deliver sustained release over 7 hours. Almost double the time of
    regular melatonin!*

  • Help fall asleep quickly.* Cuts the average time to fall asleep nearly in half!* 

  • Help stay asleep until dawn.* Released slowly over the night so you can
    sleep until morning.*

Melatonin is a hormone that helps regulate the sleep-wake cycle. Multiple human studies have shown that melatonin can help people fall asleep faster, but because it leaves the body so quickly, taking it at bedtime doesn’t help those who wake during the night or wake up earlier than they would like to in the morning. Melatonin-SR features MicroActive® Melatonin, which delivers melatonin in a special micronized, sustained-release matrix. Not only does Melatonin-SR provide an initial burst of melatonin (about 49 percent of the melatonin in each capsule) to help you fall asleep quickly, it delivers a complete release of the remaining 60 percent of the melatonin over the course of the night to help you stay asleep until dawn.*


Q: How long does the Melatonin stay in your system?

A: The MicroActive Melatonin in our Melatonin-SR formula has been shown to offer 7 hours of sustained release.

Q: How does this differ from other melatonin products on the market?

A: Unlike other Melatonin products, Melatonin-SR is released in two-stages: an initial rapid release to help you to fall asleep and then a slower sustained release to help you to stay asleep until morning.*  

Q: Is it possible for the polymers in the formula to bio accumulate over time?

A: The polymers like HPMC are not absorbed by the system. HPMC is a soluble fiber that is also not fermentable by the colon bacteria. Beta cyclodextrin  is also not absorbed from the stomach and small intestines. It can be broken down by the enzyme amylase to form open chain sugars and glucose. Carnuaba wax is highly insoluble and is not absorbed. So, all the polymers are eliminated from the GI tract, no chance of bioaccumulation.
