Melatonin is a naturally occurring hormone in the human body. The brain produces melatonin in response to darkness, and it plays a crucial role in regulating sleep-wake cycle, also known as circadian rhythms [*]. 

Studies demonstrate that constant exposure to light before bedtime can reduce melatonin levels. This reduction can disturb circadian rhythms and negatively impact sleep, thermoregulation, blood pressure, and glucose homeostasis [***].

A study also proposed that lower levels of melatonin can be a contributing factor in age-related macular degeneration (AMD). And melatonin supplementation has potential in delaying onset of macular degeneration [*]. 

Another study demonstrate the potential benefits of low-dose melatonin supplementation among individuals with  winter depression (seasonal affective disorder or SAD) [*]. 

A review by the  National Institute of Health (NIH) claims that “Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery” [*]. 

Melatonin supplements can be sourced from animals or microorganisms, as well as synthetically produced [*]. 

There are a variety of melatonin supplements in the market with varying formulations. Some contain melatonin as a single ingredient or part of a blend. Melatonin supplements are generally promoted as a sleep aid. 

The popularity of melatonin has led to hundreds of brands flooding the marketplace; however not all supplements are created equal! Unfortunately, more than 90% of melatonin supplements in the market simply DON’T WORK!

We understand the challenges in finding the right supplement for your health needs. That’s why we gathered years of research and made this guide to help you find the top-rated formulas that work for you.

Things To Be Cautious About

Has your brand been third-party tested? You should never buy supplements that don’t have Certificate of Analysis. The studies should be conducted in labs that are not affiliated with the manufacturer. These labs verify the product for safety and potency.

Does your melatonin contain cheap synthetic fillers? Some brands add artificial fillers to cut cost to offer cheap products. Some of these cheap fillers we found were titanium dioxide and artificial coloring. You should never purchase cheap products when it comes to supplements.

No return policy or customer service – A reputable supplement company will offer 100% money-back guarantee policy and provide customer support through phone number and email. We noticed many formulas out there are just copies of the top-rated brands. They don’t offer an easy refund policy or don’t even have a phone number to prove they are real.
