Why we selected this company:
Supplements for Sensitive People
Pure Encapsulations supplements are hypoallergenic. There are
absolutely no hidden fillers or coatings, binders, shellacs, artificial
colors, fragrance or excipients in their products that would disrupt or
diminish the bioavailability of any of our ingredients. Furthermore,
their products are free of wheat, yeast, gluten, corn, sugar, starch,
preservatives or hydrogenated oils.
Ingredient Quality
Their ingredients are selected solely on the basis of quality and
purity and are provided in their most potent and bioavailable forms.
They purchase premium raw materials from Japan, Switzerland, Germany,
Italy, France, and of course, the U.S. Manufacturers of ingredients
must pass rigorous pharmaceutical grade analytical tests to qualify as
Pure Encapsulations suppliers.
Manufacturing and Quality Control Excellence
They manufacture their supplements in their own state-of-the-art
facility in Sudbury, Massachusetts. Their dedication to cleanliness is
obvious from the moment their plant is entered. A large staff is
dedicated full-time to the task of ensuring that their plant is
impeccable.
Each step of the manufacturing process is governed by exacting
standards and exceeds the requirements for nutritional supplement
manufacturing. All manufacturing takes place in humidity- and
dust-controlled individual rooms. Each piece of equipment used in the
manufacture of Pure Encapsulations supplements is dismantled and
sterilized before each production run. This includes scales, mills,
blenders, powder fillers, encapsulating machines and capsule counters.
Each Pure Encapsulations lot is submitted to an independent laboratory
for final confirmation of potency and conformance with ingredient
levels. They are the only supplement manufacturer that has FDA
certified laboratories test every batch of finished, encapsulated
products. This is an important distinction from companies that use
in-house laboratories, use skip-lot testing or test ingredients prior
to encapsulation or tableting.
All of their customers have access to the test results by viewing over
200 assays available on CD, verifying their uncompromising standards.
All finished products must also pass the USP Microbial Limits Test.
Our finished products are tested by Integrated Biomolecule Corporation,
Vanguard Scientific, Eurofins Scientific and Advanced Food Micro.

MELATONIN - Sleep Disorder
Melatonin is a hormone produced in the pineal gland during the dark
hours which plays a role in the internal synchronization of the
circadian system. The timing of melatonin production is regulated by
the endogenous clock located in the suprachiasmatic nucleus of the
hypothalamus. Melatonin decreases with aging. Impaired melatonin
secretion is associated with sleep disorders in old age. Circulating
melatonin levels have been found to be significantly lower, and have
delayed onset and peak time in elderly insomniacs as compared to
age-matched controls. Subjects were evaluated for 7 consecutive days
while taking either 2 mg of melatonin in sustained-release form or
fast-release form, or a placebo 2 hours before bedtime. In a second
part of the study, subjects took 1 mg of sustained-release melatonin 2
hours before bedtime. For sleep initiation, it was found that a 1-week
treatment of the fast-release 2 mg melatonin was as effective as the 1
mg sustained-release melatonin for 2 months. Sleep maintenance was
improved only after 2 months of treatment with the sustained-release
melatonin. The beneficial effect on sleep of the fast-release tablets
may come from the high amount of melatonin released immediately after
administration, while the benefit from the sustained-release tablets
may come from the release of melatonin in small doses during the night.
The fact that sleep initiation was improved upon long-term treatment
with sustained-release melatonin suggests stabilization of the
sleep-wake cycle in melatonin-deficient elderly insomniacs. In humans,
melatonin plays a role in both synchronizing the sleep-wake cycle and
in promoting sleep. Exogenously administered melatonin may help certain
types of insomnia that are related to disturbances in normal secretion
of melatonin.

MELATONIN - Role in Health and Disease
This is an extensive review article on the role of the hormone
melatonin. Melatonin's chemical name is N-acetyl-5-methoxytryptamine.
Melatonin is secreted from the pineal gland. Its secretion is
controlled by the prevailing light-dark environment acting through the
hypothalamic suprachiasmatic nuclei. Melatonin is independent of sleep.
In mammals it is light and darkness perceived by the eyes which
synchronizes the circadian activity of the gland. In birds, light
directly penetrating the skull influences pineal function. Pineal
melatonin is inhibited by light and stimulated during darkness through
a multi-synaptic neuropathway which connects the retina, through the
suprachiasmatic nuclei of the hypothalamus, preganglionic neurons in
the upper thoracic spinal cord and post-ganglionic sympathetic fibers
from the superior cervical ganglia to the pineal gland. Sympathetic
innervation that is intact is important in melatonin secretion.
Melatonin levels continue to fall from adulthood to old age at which
time virtually no melatonin rhythm can be observed. Melatonin is well
tolerated, nontoxic and a highly diffusible substance due to its
lipophilic character and extremely high doses of up to 100 and even 300
mg per day have been used. At these high doses melatonin remains in the
circulation over 24 hours. Behavioral effects have been recently
observed after doses as low as .1 mg. The lower doses have been shown
to result in a significant fall in sleep latency. Melatonin has been
observed to be a potent inhibitor of cancer growth. Circulating
nocturnal melatonin have been found to be lower in women with estrogen
positive/progesterone positive receptors in breast cancer. Melatonin
appears to have a stimulatory effect on natural killer cells and an
antagonistic effect on stress-induced immunosuppression. The secretion
of luteinizing hormone was found to fall in women given exogenous
melatonin together with synthetic progestogen as a contraceptive. In 42
women studied throughout a treated and controlled cycle no luteinizing
hormone surges were observed at midcycle and in the treated cycles.
These women received both melatonin and norethisterone. There has been
an association between the diurnal and seasonal rhythmicity of
melatonin production and seasonal affective disorder in various types
of endogenous depression. Investigators have evaluated melatonin
concentration in the blood, central nervous system and vitreous humor
from 32 infants who died with Sudden Infant Death Syndrome (SIDS) and
compared them to values with another group of 36 children who died from
other causes. After adjusting for variables melatonin was significantly
lower in the SIDS children and these differences were maintained when
only infants age 3 months or less were considered. A deficient
maturation of endogenous melatonin rhythm reflecting in an abnormal
maturation of sympathetic nervous system may play a part in Sudden
Infant Death Syndrome (SIDS). Weissbluth and Weissbluth (1994) have
found a failure of the normal pineal gland development and melatonin
secretion resulting in a chemical imbalance between serotonin,
progesterone and catacholamines ending in SIDS as a result of
neurotoxic and cardiomyotoxic effects of abnormally elevated
catecholamines and intracellular calcium ions. Aside from a visible
light, certain nonvisible ultraviolet wave lengths and extremely low
frequency electromagnetic fields may influence melatonin rhythm. The
inhibitory effect of pulse intermittent static magnetic fields on
nocturnal metabolism of serotonin to melatonin in the mammalian pineal
gland have been observed. The physiologic relevance of this is unknown
in man. The potentially hazardous effects of electromagnetic fields on
melatonin disturbances should not be ignored given the ever increasing
exposure to man made magnetic fields in industry, offices and homes as
well as natural electric and magnetic fields.

Benefits for the body:
Supports the body's natural sleep cycle
Interesting facts:
Melatonin is a hormone produced by the pineal gland, the organ that
regulates the body’s wake/sleep/wake cycle. The hormone is activated by
darkness and depressed by light. As people age, their sleep quality
often undergoes significant deterioration, commonly characterized by
frequent and longer-lasting nighttime awakenings. In many older people,
sleep disturbance is correlated with a decline in melatonin secretion.
A number of published studies also show that decreased melatonin
production is associated with the onset of a host of degenerative
diseases.
