Benefits of MELATONIN Supplementation
Study-Supported Benefits of
MELATONIN Supplementation
Supplementing with MELATONIN
is appropriate in certain situations
However, be aware that chronic
use of supplemental MELATONIN
in younger people can result in the pineal gland becoming lazy
For older people
( > 60 yrs) - daily MELATONIN
supplementation can be useful, since their pineal gland is not producing enough
.
To synchronize perturbed sleep and circadian rhythms -
sustained desynchonisation of the "Biological Clock" has a profound
impact on health and wellbeing, including suppressed immunity and increased risk
of cancer. Also, frequently accompanying these disturbances are neuropsychiatric
disorders, such as depression, schizophrenia and Alzheimer's. Desynchronisation
occurs while the body's clocks struggle to adapt to an abruptly shifted external
light/dark cycle. E.g.
Frequent
trans-meridian travel (Jet Lag). E.g. Transcontinental
flight personnel and frequent overseas fliers. Supplement
MELATONIN on the day of the flight and continue
for five days thereafter.
Shift-workers.
MELATONIN
supplements may simulate the MELATONIN production
at different times that does not occur during regular sleeping hours for people
who work night shifts.

Prevent ischemic damage -
in rats, reduces tissue damage due to ischemia in brain and heart; (ischemia
is a restriction in blood supply causing a shortage of oxygen delivery to target
organs/tissues)
Against cardiovascular disease - Low nighttime MELATONIN has been reported
in patients with coronary heart disease and heart failure. Similarly, thelinkbetween
highCORTISOL andhypertension is well established.Supplementationwith
MELATONIN has been shown to increase cardiac
vagal tone, decrease circulating NOREPINEPHRINE, and reduce blood pressure.

Learning, memory and Alzheimer's -
first published evidence that MELATONIN may
be useful in Alzheimer's disease demonstrated that this neurotransmitter/hormone
prevents neuronal death caused by exposure to the amyloid beta protein, a neurotoxic
substance that accumulates in the brains of patients with the disorder.

MELATONIN also inhibits the aggregation
of the amyloid beta protein into neurotoxic microaggregates which seem to underlie
the neurotoxicity of this protein, causing death of neurons and formation of neurofibrillary
tangles, the other neuropathological landmark of Alzheimer's disease.

ADHD -
research shows that after MELATONIN
is administered to ADHD patients on
methylphenidate , the time needed to fall asleep is significantly
reduced. Furthermore, the effects of the MELATONIN
after three months showed no change from its effects after one week of use.

Migraines / Headaches - several
clinical studies indicate that MELATONIN
supplementation is an effective preventative and adjunct treatment
for migraines and cluster headaches.

- research shows that depressed patients have lower levels of

although MELATONIN supplementationhelps correctsleep

Gallbladder stones -
in the gallbladder, MELATONIN
converts cholesterol to bile, prevents oxidative stress and increases mobility of
gallstones from the gallbladder. It also decreases the amount of cholesterol produced
in the gallbladder by regulating the cholesterol that passes through the intestinal
wall. In guinea pigs, MELATONIN administration
restored normal function after induced cholecystitis, by reducing inflammation.

In animal models, MELATONIN
has been shown to ameliorate glutamate-induced neuronal death, presumed due to its

(300mg/day for 2 years) was shown to be tolerated well.

Obesity - studies in
experimental animals show that long-term MELATONIN
supplementation in drinking water reduces body weight and abdominal fat,
without changes to diet or being more active (especially in middle-aged rats)
Daily MELATONIN administration
to middle-aged male rats suppresses body weight, intraabdominal adiposity, and plasma

Protection from radiation -
animal
and
human (2nd
Ref ) studies have shown MELATONIN
to provide more efficient protection from ionizing radiation than the commonly
used drug amifostine.
Its mechanism is thought
due to the scavenging of harmful oxidants (E.g. free radicals),
considered to be responsible for ~70% of ionizing damage to body tissues, especially
the hydroxyl radical that attacks DNA, proteins, and cellular membranes.
MELATONIN has the advantage of being
broadly protective, readily available for oral supplementation, and without significant
side effects .
Tinnitus -
medical studies with adult patients show beneficial results in the
treatment of tinnitus with MELATONIN
MELATONIN
is associated with a statistically significant decrease in tinnitus intensity and
improved sleep quality in patients with chronic tinnitus -
MELATONIN is most effective in:
Men
Those without a history of depression
Those who have not undergone prior tinnitus
treatments
Those with more severe and bilateral tinnitus
Those with a history of noise exposure.

One publication
explores the possible mechanisms of how MELATONIN works against tinnitus:
Its modulatory effect on central nervous system
- resulting in a protective mechanism against an exaggerated sympathetic drive
(sympathetic nervous system is responsible for regulating homeostatic conditions
in the body);
Its capacity to induce a more steady hemodynamic
condition - through a multifactorial and multi-organ activity, resulting in
more regular blood flow in the inner ear;
A possible action on the skeletal muscle tending
to a reduction of the muscular tone - which could relieve tinnitus of muscular
origin deriving from contraction of tensor tympani muscles (located in the upper
auditory canal) responsible for dampening sounds;
Its possible reported anti-depressive effect
- which could indirectly act on tinnitus;
A direct regulation of inner ear immunity
- as proposed in literature when melatonin was reported to be present in the
inner ear.
