  1. I have tried other brands of melatonin with more mg than Cooper’s only to be extremely disappointed. This is truly pharmaceutical strength/grade and it works!

Product Details

Product Description

Melatonin has been shown to help regulate sleep/wake cycles, support normal immune function and protect cells from free radical damage.† At night or in the dark, the body’s melatonin production rises but the amount produced begins to decline from adolescence until it is virtually absent in the elderly. Prolonged Release Melatonin supplement is recommended for individuals who have difficulty sleeping. Specifically designed for those who fall asleep, but then awaken later and have difficulty returning to sleep, Prolonged Release Melatonin supplement releases 3 mg of melatonin slowly over an 8 hour period.†

The leading cause of fatigue is poor sleep. Quality of sleep and quantity of sleep are to blame for most cases of fatigue. The National Sleep Foundation recommends seven to nine hours of sleep per night for adults to feel rested and function at maximum capacity during the day. (Adults 65 years and older, need seven to eight hours of sleep per night.) In reality, most American adults get between five and six hours of sleep per night, and some get even less. The amount of time you sleep at night is extremely important towards feeling well-rested.

In several human studies, researchers found that melatonin supplementation reduces the number of days needed to establish a normal sleep pattern. Travelers took melatonin on the day of travel (close to the target bedtime of the destination) and for several days thereafter. Looking at several studies on the impact of melatonin and jet lag, melatonin seemed to provide benefits for about half the people studied.

Frequently Asked Questions

How does Prolonged Release Melatonin work?

Prolonged Release Melatonin is slowly released into the body over several hours. Prolonged Release Melatonin is for those who can fall asleep quickly but then have difficulty staying asleep.

What is Melatonin?

Melatonin, a hormone produced by the pineal gland in the brain, helps control sleep and wake cycles, essentially the internal clock in our body. Melatonin plays a role in regulating our natural wake-sleep cycle (circadian rhythm), with levels of melatonin increasing as exposure to light decreases, and decreasing with light exposure increases.

Is there anyone who should not take Melatonin?

Because melatonin is a hormone, testosterone and estrogen metabolism may be affected. For this same reason, women who are pregnant, or couples who are attempting to conceive should not take melatonin.

Diabetics, those with low-blood pressure (naturally or through medications), and individuals taking warfarin or other blood thinning medications should talk with their physician before taking melatonin.

Will Melatonin make me drowsy or “hungover” the following day, like many prescription sleep aids?

Unlike many prescription sleep aids, melatonin doesn’t increase drowsiness or have a “hangover” effect the following day. However, Melatonin should not be taken when fewer than 8 hours remain for sleep/rest.

Will Melatonin change my dreams?

Possibly. Some individuals taking Melatonin report vivid dreams.

Does Melatonin help jet lag?

In several human studies, researchers found that melatonin supplementation reduces the number of days needed to establish a normal sleep pattern. Travelers took melatonin on the day of travel (close to the target bedtime of the destination) and for several days thereafter. Looking at several studies on the impact of melatonin and jet lag, melatonin seemed to provide benefit for about half the people.

I tend to keep a regular sleep schedule during the week and then stay up late on weekends. Would Melatonin help me get to sleep at my normal time on Sunday evening?

Delayed Sleep Phase Syndrome (DSPS) is the scientific term for delayed weekend sleep pattern, or the difficulty that many people experience each Sunday night trying to get back onto their “weeknight” sleep schedule after staying up much later on Friday and Saturday night. One study showed the time taken to fall asleep was reduced from almost 60 minutes to a few seconds over 20 minutes.

Does Melatonin help sleep in the elderly?

Several human studies have found that taking melatonin before bedtime reduces the time it takes to fall asleep in elderly individuals with insomnia. Improved sleep quality and morning alertness were also found. Unfortunately, the studies were short in duration.

Can I take this product if I am also taking Coumadin or Warfarin?

If you are taking Coumadin or Warfarin, we recommend consulting your doctor before adding any supplements to your diet.
