Melatonin Serotonin Melatonin Level -
Sublingual Melatonin or Time Release Melatonin
Melatonin, the pineal hormone, became available over the counter in 1994.
Melatonin is a hormone released each night to help us sleep. In addition to
sleep, melatonin has many other benefits. Melatonin is available as a capsule to
swallow and as melatonin sublingual under the tongue. Melatonin is made from
serotonin. A melatonin level is not necessary to know before using a melatonin
product. A sublingual melatonin may work quicker but time release melatonin may
sustain sleep longer. For more up to date

Melatonin Source Naturals
Melatonin supplement sustained release form of melatonin provides a slower, more physiological
absorption.
Suggested Use: 1/3, 1/2 or a full melatonin supplement one to 4 hours before bedtime.
Melatonin works best
if used only a few times a week as opposed to nightly.

Benefits of Melatonin:
1.
Lessens the effects of jet lag. Daily doses of melatonin, at 1 to 5 mg, taken an hour or
two before bedtime at the new destination for 2 to 4 days may be helpful in reducing
symptoms of jet lag. It's very difficult to know exactly the dosage of melatonin
that would be effective. There is a wide range of individual response to
melatonin.
2.
Is a strong antioxidant.
Evidence continues to accumulate regarding the antioxidant
benefits of melatonin. In laboratory studies, melatonin has been found to stimulate
natural antioxidant systems in addition to offering protection to the DNA present within
cells. While these effects have been observed primarily using pharmacological (very large)
doses of melatonin, in a small number of experiments melatonin has been found to have
antioxidant properties in small, physiological doses as well. The ability of melatonin in
inhibiting oxidative damage has been tested in a variety of neurological diseases where
free radicals have been suspected as being in part causative of the condition. Thus,
melatonin has been shown to reduce amyloid protein toxicity of Alzheimer's
disease, to reduce oxidative damage in some types of Parkinson's disease, to
reduce brain injury when exposed to low blood or oxygen flow, and to lower brain
damage due to a variety of toxins.
Low dose melatonin treatment in mice
enhances the body's natural anti-oxidant system, and this may have anti-aging
properties. This study has convinced me to take 0.1 or 0.2 mg of melatonin a
couple of nights a week. I have a melatonin pill of 0.5 mg and I take a portion
of it about an hour to three hours before bed.
3.
Melatonin may enhance the immune system. The details are fuzzy.
4.
May have anti-tumor abilities. There's been quite a
few studies with melatonin and cancer, most of them done in Italy. Most of the
studies have shown benefits using 10 to 40 mg of melatonin nightly. However,
much is yet to be learned about this approach, and hardly any oncologists in the
US are familiar with the use of melatonin as an anticancer agent. Therefore, at
this point, the use of melatonin is still experimental. However, since cancer is
ultimately a fatal disease in most cases, it may be worthwhile to try melatonin.
Your physician can easily access all the research on Medline.
5. Melatonin may have anti-aging potential due to its anti-oxidant
properties. We won't know for sure for many years to come if melatonin
increases longevity, nor will we know in the near
future the ideal dosage, timing, and frequency.
6. Melatonin enhances dreams. This could lead to vivid,
enjoyable and memorable dreams or, on the flip side, vivid nightmares. Melatonin
enhances REM sleep.
Melatonin and serotonin relationship
Serotonin converts to melatonin at night in the pineal gland to help us sleep.
Taking a serotonin precursor such as 5-HTP can lead to more melatonin
production.
Melatonin - Less is More
MIT scientists confirm that melatonin is an
effective sleep aid for older insomniacs and it appears that only a small
dose of melatonin (about 0.3 milligrams) is necessary for a restful
effect. Taken in that quantity, melatonin not only helps people fall
asleep, but also makes it easier for them to return to sleep after waking
up during the night. However, the amount in most melatonin products on the
market ranges between 1 to 5 mg. At this high dose, tolerance can develop
and the melatonin receptors in the brain become unresponsive. Thereafter,
melatonin becomes less effective.
Melatonin level
Is it necessary to have a blood test for melatonin level? We don't think so. A
melatonin level is not necessary to know before taking a melatonin pill. As we
age, it is possible that some people have a lower blood melatonin level at
night.
Sublingual
melatonin. Should I take the regular melatonin pills, melatonin sublingual, or the time release?
Can melatonin be taken with food?
A. Most of the melatonin presently on the market is the
regular 3 mg pill to swallow or as sublingual melatonin. You may want to cut this pill into a fifth or even a tenth
and use this dose your first night, about an hour or two before bed without food
in your stomach.
Alternatively, you can also purchase melatonin pills at 1 mg or sometimes even
lower dosages are sold. If this low dose is effective, then you may keep using
it as needed for sleep. If you don't feel any effect, then take a little more
the following nights.
If your main problem is falling
asleep, then try the melatonin sublingual form, in the
range of 0.3 to 1.0 mg, about an hour or two before bed. Sublingual melatonin
could work quicker and is a good option if you already have food in your stomach
since if you take a melatonin pill with food, it may not absorb as well or as
quickly. However, some people
wake up in the middle of the night, or early morning, feeling alert. Most of
these people would want to sleep a couple of hours longer. Melatonin has a short
half-life and therefore is metabolized very fast and will be out of the body
soon. This explains why many people wake up early.
In order to stay asleep longer, a
good option is slow-release melatonin, which is released consistently throughout
the night. Slow-release (also known as sustained, time or controlled-release)
melatonin will likely become more popular in the future. Another form that is
useful is melatonin tea. The tea is drunk about an hour before bed. One company
has added half a mg of melatonin to their tea bag.
Melatonin Research Update
Melatonin: An Anti-Aging Hormone Supplement? -- Ever
since melatonin became available over the counter in 1994, it has created a lot
of controversy. The medical establishment has been quite uneasy with this
hormone being available without a doctor's prescription, and I remember back in
the mid 1990s quite a number of articles were published in journals read by
doctors warning them of potential serious side effects. This surprised me since
my evaluation of the research did not indicate that melatonin was dangerous. It
has been a decade since melatonin has been freely sold to the public, and to my
knowledge there have not been any published studies to indicate that this
hormone has caused any serious harm. In fact, more research continues to be
published regarding its benefits. Numerous studies now indicate that melatonin
has powerful antioxidant properties, in addition to its known hormonal
activities which includes sleep inducement . A recent study published at the
University of Rajasthan in Jaipur, India investigated the influence of low-dose
chronic administration (0.10 mg/kg body weight/day for 3 months) of melatonin
against age-induced oxidative stress in mice tissues, namely brain, liver,
spleen and kidney. Sixteen-month-old mice were supplemented with melatonin for
three months and then autopsied (at the age of 19 months). The results indicated
that melatonin was able to significantly reduce the age-induced decline in the
body's natural antioxidant system. The researchers state, "These findings
indicate that low-dose chronic administration of melatonin acts as a free
radical scavenger and anti-aging agent."
Comment: Research thus far is convincing that
melatonin has many beneficial properties. However, it is difficult to determine
the ideal dosage and frequency of melatonin use in humans. At this time it would
seem safe and prudent to take a low dose, such as 0.1 to 0.5 mg of melatonin a
few nights a week, particularly for those who suffer from insomnia. Melatonin is
best taken on an empty stomach about 1 to 3 hours before bedtime. Since most
pills come in dosages ranging from 0.5 to 3 mg, you could bite off a small
portion of the pill.
Melatonin Pharmacotherapy for Nocturia in Men With
Benign Prostatic Enlargement.
Drake MJ, Mills IW, Noble JG. J Urol. 2004;171:1199-1202.
Nocturia is a common condition often attributed in
aging men to benign prostatic enlargement. Older adults are prone to nocturnal
sleep disturbance, of which disturbed circadian rhythm may be a component since
it improves with nighttime administration of melatonin. This study was designed
to investigate melatonin as a potential treatment for nocturia associated with
bladder outflow obstruction in older men. A total of 20
men with urodynamically confirmed bladder outflow obstruction and nocturia were
entered into a randomized, double blind, placebo controlled crossover study
assessing the effect of 2 mg controlled release melatonin at night on nocturia.
Symptoms were assessed at baseline and after each 4-week treatment period using
a frequency volume chart, the International Prostate Symptom Score and symptom
problem index. Maximum urinary flow rate and post-void residual urine volume
were also assessed. Baseline frequency of nocturia was 3.1 episodes per
night. There were 7 men (35%) with detrusor overactivity and 10 (50%) had
nocturnal polyuria. Melatonin and placebo caused a decrease in nocturia of 0.32
and 0.05 episodes per night (p = 0.07) and a decrease in the nocturia bother
score of 0.51 and 0.05, respectively (p = 0.008). Nocturia responder rates (a
reduction from baseline of at least -0.5 episodes per night) differed between
the active medication and placebo groups. Daytime urinary frequency,
International Prostate Symptom Score, relative nocturnal urine volume, maximum
urinary flow rate and post-void residual were unaffected by melatonin treatment. Melatonin treatment is associated with a significant nocturia
response rate, improvement in nocturia related bother and a good adverse effect
profile. However, it is uncertain whether the observed changes in this study are
clinically significant.
Long term Melatonin Safety
Melatonin has been recommended for the treatment of insomnia and jet lag, yet
little is known about its long term effects on the body, and some in the medical
community have questioned its safety. Researchers at the University of Lodz in
Poland. evaluated the effects of melatonin administration on sleep and routine
blood chemistry in elderly women. The study was performed on 14 women aged from
64 to 80 years. Melatonin 2 mg was given at 7 pm nightly for 6 months. Before
and after melatonin treatment blood samples were taken in the morning after an
overnight fast. The total blood count, glucose, total cholesterol, LDL, HDL, and
triglycerides were measured by routine laboratory methods. Thirty-six percent of
those on melatonin had an improvement in general sleep quality. Melatonin
treatment did not influence significantly either total blood count, glucose or
blood lipids levels. The researchers conclude that on the basis of this
preliminary open study it seems that melatonin administration may be safe for
elderly subjects.
Comments: It’s reassuring to know that blood chemistry was not affected
in any significant adverse way by 6 months therapy with melatonin. On the basis
of this preliminary study, it seems that elderly individuals should be quite
safe if they use melatonin one to three times a week at a dose of 0.1 or 0.5 mg.
Melatonin in patients with reduced REM sleep duration: two
randomized controlled trials.
Department of Psychiatry and Psychotherapy, Charite Campus
Mitte-Universitatsmedizin Berlin, 10117 Berlin, Germany.
J Clin Endocrinol Metab. 2004 Jan;89(1):128-34.
Recent data suggest that melatonin may influence human physiology, including the
sleep-wake cycle, in a time-dependent manner via the body's internal clock.
Rapid-eye-movement (REM) sleep expression is strongly circadian modulated, and
the impact of REM sleep on primary brain functions, metabolic processes, and
immune system function has become increasingly clear over the past decade. In
our study, we evaluated the effects of exogenous melatonin on disturbed REM
sleep in humans. Fourteen consecutive outpatients (five women, nine men; mean
age, 50 yr) with unselected neuropsychiatric sleep disorders and reduced REM
sleep duration (25% or more below age norm according to diagnostic
polysomnography) were included in two consecutive, randomized, double-blind,
placebo-controlled, parallel design clinical trials. Patients received 3 mg
melatonin daily, administered between 2200 and 2300 h for 4 wk. The results of
the study show that melatonin was significantly more effective than placebo:
patients on melatonin experienced significant increases in REM sleep percentage
(baseline/melatonin, 14.7/17.8 vs. baseline/placebo, 14.3/12.0) and improvements
in subjective measures of daytime dysfunction as well as clinical global
impression score. Melatonin did not shift circadian phase or suppress
temperature but did increase REM sleep continuity and promote decline in rectal
temperature during sleep. These results were confirmed in patients who received
melatonin in the second study (REM sleep percentage baseline/placebo/melatonin,
14.3/12.0/17.9). In patients who received melatonin in the first study and
placebo in the second, the above mentioned effects outlasted the period of
melatonin administration and diminished only slowly over time (REM sleep
percentage baseline/melatonin/placebo, 14.7/17.8/16.2). Our findings show that
exogenous melatonin, when administered at the appropriate time, seems to
normalize circadian variation in human physiology. It may, therefore, have a
strong impact on general health, especially in the elderly and in shift workers.

Q. I read a report on melatonin that recommends to take it only 3 times a week
and in low dosages. However,
does this refer to all age groups? I am 66 years old (female) and certainly low
in melatonin. I sleep very badly.
A. The guidelines on melatonin use are general and flexible, and we
suggest reading about how to get deeper
sleep at this website.
Q. Is melatonin a vitamin since it is over the
counter?
A. Melatonin is not a vitamin but classified as a hormone.
Q. Can I take melatonin if i am on Prozac?
A. Some people find Prozac to cause insomnia or sleep disturbances,
melatonin may not work as well for those taking Prozac or other SSRIs since the
serotonin system may be disturbed.
Q. Does supplementing with melatonin increase the
levels of serotonin either in the brain or peripherally? Also, would taking
melatonin be contra-indicated for someone who has exhibited symptoms of
serotonin syndrome in the past?
A. We don't think melatonin taken as a supplement in a dosage of
less than 3 mg will have much of an influence on serotonin levels in the brain
or peripherally. Melatonin does not seem to be involved in serotonin syndrome.
Q. I am a 64 year old woman who until the age of 55
never had a sleep problem, as soon as i started menopause i start having
insomnia, my doctor prescribe me 0.5mg Ativan and i have been taking it every
night for about 2 years, then the 0.5mg stop working my doctor doubled the dose,
after a while that also stop working it takes hours to fall asleep, i read the
article about melatonin on your web site and i said to myself it's worth the
try. My question is shall i stop the Ativan while i am taking the melatonin i
decided to take a low dose 2 times a week.
A. Natural sleep pills such as melatonin are not recommended to be
taken the same night as a pharmaceutical sleeping pill. It is best to take
melatonin on a night that a person is not taking prescription sleep meds.
However, there is sometimes a rebound effect on sleep when a drug is stopped.
The rebound effect means that it is difficult to sleep since the brain is used
to getting the sleep drug. Thus, when a natural sleep pill such as melatonin is
taken, it may appear that it is not working since it has to overcome the rebound
effect. It is best to follow all suggestions for a deeper sleep as mentioned at
sleep web page.
Q. In the past, I have purchased 3mg chewable lemon
flavored melatonin. This is for a 5 year old child with medical problems. The
place we purchased it from is no longer in business and I can not seem to find
this anywhere. Is there anything you can do to tell me if this is offered.
A. We don't carry lemon flavored chewable melatonin pills. The 1 mg
sublingual melatonin pill we link to is peppermint flavored.
Q. Could melatonin cause burning mouth, that is the
only thing that I can think of that may cause this as I do not take meds. I just
hate this problem and have had it for years now. Could it be
long term effects of taking melatonin? I already take R- alpha lipoic acid and
that is not helping.
A. We have had no reports from anyone that melatonin causes burning
mouth. We know people who have given us feedback on
long term effects of taking melatonin and no burning mouth has been reported.
Q. I have been reading and researching the benefits of
melatonin on your site as well as other internet sites. There seems to be many
benefits to at least some level of melatonin supplementation. However, some
information that has alarmed me regarding the artificial increase of melatonin
through supplementation is that increased melatonin can decrease the amount of
serotonin in your body (more importantly, the brain). Couldn't this reduction in
serotonin lead to depression? Can you shed some insight on this?
A. We don't know exactly what influence melatonin supplements have
on serotonin levels when used for prolonged periods, but we do have reports of
mild depression with high dose regular melatonin supplement use.
