Health Notes

Melatonin

Melatonin
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Macular Degeneration
Dose: Take under medical supervision: 3 mg daily at bedtime

In a preliminary trial, supplementation with melatonin (3 mg per day at bedtime for at least three months) resulted in an improvement in the abnormalities observed on eye examination in the majority of cases.1 Melatonin is believed to work by regulating eye pigmentation (and, consequently, the amount of light reaching the retina) and by functioning as an antioxidant.

Alzheimer's Disease
Dose: Refer to label instructions

In a double-blind trial, supplementation with prolonged-release melatonin (2 mg each night for 24 weeks) significantly improved cognitive function and sleep quality, compared with a placebo, in patients with Alzheimer's disease.1 The beneficial effect of melatonin was more pronounced in patients who were suffering from insomnia than in those who were not, suggesting that poor sleep quality contributes to impaired cognitive function in people with Alzheimer's disease.

Age-Related Cognitive Decline
Dose: Refer to label instructions

Melatonin is a hormone secreted by the pineal gland in the brain. It is partially responsible for regulating sleep-wake cycles. Cognitive function is linked to adequate sleep and normal sleep-wake cycles. Cognitive benefits from melatonin supplementation have been suggested by preliminary research in a variety of situations and may derive from the ability of melatonin to prevent sleep disruptions.1, 2, 3, 4 A double-blind trial of ten elderly patients with mild cognitive impairment showed that 6 mg of melatonin taken two hours before bedtime significantly improved sleep, mood, and memory, including the ability to remember previously learned items.5 However, in a double-blind case study of one healthy person, 1.6 mg of melatonin had no immediate effect on cognitive performance.6

The long-term effects of regularly taking melatonin supplements remain unknown, and many healthcare practitioners recommend that people take no more than 3 mg per evening. A doctor familiar with the use of melatonin should supervise people who wish to take it regularly.

Cluster Headache
Dose: Take under medical supervision: 10 mg daily in the evening

Researchers have found low levels of the hormone melatonin in cluster headache patients.1, 2, 3, 4 In a small double-blind trial, a group of cluster headache sufferers took a 10 mg evening dose of melatonin for 14 days. About half of the group saw a significant decrease in the frequency of their headaches within three to five days, after which no further headaches occurred until melatonin was discontinued.5 Melatonin appears to be effective against both types of cluster headache (e.g., episodic and chronic). 6 More research is needed to establish the long-term effects of melatonin supplementation on cluster headache.

Migraine Headache
Dose: Refer to label instructions

The function of the pineal gland and its cyclic secretion of melatonin may be disturbed in people with migraine headaches.1 Preliminary evidence suggests that 5 mg per day of melatonin, taken 30 minutes before bedtime, may reduce symptoms of migraine headache.2 However, a double-blind trial found that taking 2 mg of melatonin 1 hour before bedtime each day for 8 weeks was not more effective than a placebo for decreasing migraine frequency.3

Fibromyalgia
Dose: Refer to label instructions

Melatonin supplementation may be useful in the treatment of fibromyalgia. In a preliminary trial, 3 mg of melatonin at bedtime was found to reduce tender points and to improve sleep and other measures of disease severity, though pain and fatigue improved only slightly.1

Insomnia
Dose: Take under medical supervision: 0.5 to 3.0 mg daily one to two hours before bedtime

Caution: Melatonin is a potent hormone and its long-term safety is not established. Melatonin should only be taken with medical supervision.

Melatonin is a natural hormone that regulates the human biological clock. The body produces less melatonin with advancing age, which may explain why elderly people often have difficulty sleeping1 and why melatonin supplements improve sleep in the elderly.2

Middle-aged adults (average age, 54 years) with insomnia also have lower melatonin levels, compared with people of the same age without insomnia.3 However, there is not much research on the use of melatonin for sleep problems in middle-aged people.

Double-blind trials have shown that melatonin facilitates sleep in young adults without insomnia,4 but not in young people who suffer from insomnia.5However, one trial found that children with sleep disturbances stemming from school phobia had improved sleep after taking 1 mg of melatonin per night for one week, then 5 mg per night for one week, then 10 mg per night for a third week.6

The results of one double-blind trial also indicate that a controlled release melatonin supplement providing 2 mg per day improves sleep quality in people with schizophrenia.7

Normally, the body makes melatonin for several hours per night-an effect best duplicated with controlled-release supplements. Trials using timed-release melatonin for insomnia have reported good results.8 Many doctors suggest taking 0.5 to 3 mg of melatonin one and a half to two hours before bedtime. However, because melatonin is a potent hormone, the long-term effects of which are unknown, it should be taken only with the supervision of a doctor.

Jet Lag
Dose: Take under medical supervision: 0.5 mg daily at bedtime for four days after arriving at your destination

Melatonin is a natural hormone that regulates the human biological clock and may be helpful in relieving symptoms of jet lag, according to some,1, 2 though not all,3, 4 double-blind studies. One double-blind trial, involving international flight crew members, found that melatonin supplementation was helpful when started after arriving at the destination but not when started three days before leaving.5 Another double-blind study compared various amounts and forms of melatonin taken at bedtime for four days after the flight by people who traveled through six to eight time zones.6 Fast-release melatonin supplements were found to be more effective than the controlled-release supplements. A 5 mg and 0.5 mg fast-release melatonin were almost equally effective for improving sleep quality, time it took to fall asleep, and daytime sleepiness.

Insomnia and Tinnitus
Dose: Take under medical supervision: 3 mg daily at bedtime

Caution: Melatonin is a potent hormone and its long-term safety is not established. Melatonin should only be taken with medical supervision.

In a double-blind trial, melatonin supplementation (3 mg taken nightly) improved symptoms of tinnitus.1 Although improvement did not reach statistical significance for all participants, the results were significant in those who reported more severe symptoms (such as two-sided vs. one-sided tinnitus). Among participants who had difficulty sleeping due to tinnitus, 47% of those who took melatonin reported sleep improvement after one month, compared with only 20% of those who took the placebo. Similar improvements in tinnitus were reported in a preliminary trial that used 3 mg of melatonin each night for four weeks.2

Sunburn
Dose: Apply a formula containing 2% vitamin E, 5% vitamin C, and 1% to 2.5% melatonin before sun exposure

Antioxidants have been studied as topical agents for protection against sunburn. Animal studies have found sunscreen-like effects from topical application of a vitamin C and vitamin E combination, and a controlled human study reported ultraviolet protection from the use of a lotion containing 0.02% to 0.05% of the selenium-containing amino acid known as selenomethionine.1, 2 The topical use of the hormone melatonin has been shown to protect human skin against ultraviolet rays in double-blind research.3, 4 A double-blind human trial tested topical vitamins C and E and melatonin, alone and in combinations, and found the highest degrees of protection from combination formulations containing 2% vitamin E, 5% vitamin C, and 1% to 2.5% melatonin.5 Other studies in which topical antioxidants were applied after ultraviolet exposure have found no benefits.6, 7

Irritable Bowel Syndrome
Dose: Take under medical supervision: 3 mg daily at bedtime

Melatonin plays a role in the regulation of gastrointestinal function and sensation. In a double-blind trial, people with irritable bowel syndrome and associated sleep disturbances received 3 mg of melatonin or a placebo at bedtime for two weeks. Compared with the placebo, melatonin significantly decreased the severity of abdominal pain, although it did not affect bloating, stool frequency, or sleep patterns.1 Melatonin was also effective in another double-blind trial.2

Hypertension
Dose: Take under medical supervision: 2 mg daily of sustained-released supplment at night

In a double-blind study, supplementation with 2 mg of sustained-release melatonin each night for four weeks significantly reduced nighttime systolic blood pressure, compared with a placebo, in people with nocturnal hypertension.1 Normally, blood pressure declines at night. People with hypertension who do not have this nighttime blood pressure decline are at increased risk of developing and dying from heart disease. Melatonin supplementation may therefore be beneficial for this subgroup of people with hypertension.

      Comments about BIOTAB NUTRACEUTICAL 1009162 Alteril™:

      This was an odd sleep aid for me. After about 2 weeks of taking it I found myself dreaming while awake and having more lucid dreams. It was interesting. Hinestly, even though it was a weird side effect I thought it was cool. It helped me sleep too but the dreaming thing was awesome.

        I take 2 tablets about an hour before I would like to be asleep. I sleep better than ever and I have tried many products

                I was VERY excited about this product as I have been having sleep problems for some time now. A friend who has had similar sleep issues gave me a few of these to try and they seemed to work! I went ahead and bought 2 boxes with the little money I have (currently unemployed) but for some reason they aren't working now. I have no idea why and needless to say I am VERY disappointed!

                After suffering with insomnia for many years, I consulted with a highly rated sleep specialist. He recommended a prescription drug (with many cautions and side effects). I do not want to become dependent and didn't want the side effects, so I researched other options. Alteril had the best ratings and most favorable natural ingredients. I ordered them and from the very first night got good to great results.
                They take awhile to kick in, but they work. I get sleep, without waking up all night long, and get up feeling great, not groggy.

                I dont have problems sleeping, but its hard for me to settle down at night and want to sleep. Also i require more sleep than the average person in order to feel rested. This product definitely keeps me sound asleep all night. I actually take half the normal dose because if i take 2 pills i feel groggy the next morning. The problem is, with a half dose it doesn't make me want to go to sleep enough. But thats just me. This product works well. I wake up feeling rested and refreshed. Im glad I bought it and will probably buy it again.

                    I followed the directions for taking this supplement as ordered. However, there was no effect on my system whatsoever. I tried taking it again the next night, doubling the dose with still no effects. I figured third time was the charm but even after tripling the dose, nothing happened. I feel like I wasted my money and time

                        I have been on Ambien for years and then Lunesta. I hate the side effects (I was foraging at night and eating really unhealthy things - I would remember nothing). I started looking for alternatives. Tried Melatonin and a few other things - nothing even came close. I finally tried Alteril and it works for me! I am an elementary teacher, dancer, I take classes, and I am very active. I need regular restful sleep.
