Melatonin Sustain 1mg 120 tablets - melatonin for a slow and gradual absorption | Jarrow Formulas
Jarrow Formulas Melatonin Sustain contains melatonin, the hormone that is secreted by the pineal gland that aids biorhythm regulation. Biorhythm is disturbed by stress, crossing time zones and changing work shifts. Melatonin production also declines with age. Vitamin B6 aids melatonin metabolism.
who may benefit from taking melatonin?
those that work in shifts or travel across time zones
what distinguishes Melatonin Sustain from other similar products?
Melatonin Sustain has a safe dose of melatonin and also contains vitamin B6 and magnesium for an even higher effectivity.
It also is produced as a sustained release tablet, so will be released slowly over time after ingestion.
Millions of Americans suffer from sleep difficulties, spending a fortune on sleeping pills despite side effects. Yet sleep problems can often be traced to by-products of modern life. Caffeine, alcohol and sedentary lifestyles have an impact, but so do light and other forms of electromagnetic radiation.
The production of melatonin by the human body falls and rises with the light-dark cycle in the environment. In fact, melatonin acts like a metronome, keeping time with the sun and allowing “scheduling” of physiological processes. This timekeeper role is the reason why melatonin is often referred to as a “chronobiotic.” Jet-lag is the most common way of understanding this experientially. But the impact of melatonin on sleep is just one aspect of this amazing molecule.
First, although melatonin possesses excellent oral bioavailability, it has a very short half-life (15-45 minutes) once it reaches the bloodstream. Together, this leads to blood levels that can be hundreds or thousands of times higher than produced by natural secretion, even when consuming only a few milligrams, and then those spiked levels drop off quickly. Melatonin Sustain overcomes these limitations with timely, balanced melatonin release along with vitamin B 6 to support melatonin metabolism.
The Sleep Regulator
Supplementation with melatonin is known to reduce sleep latency, or the time required to fall asleep. In addition, some people report improvement in feelings of sleep quality when taking melatonin. Under normal circumstances consuming melatonin 30-90 minutes before bedtime advances sleep phase and promotes sleep.
But melatonin may also prove useful for occasional sleep difficulties secondary to other causes related to mood, mental-health, age, and hospitalization. In fact melatonin is one of the few dietary supplement ingredients that has been researched with some rigor in children experiencing sleep difficulties, including those experienced as side effects of attention-hyperactivity stimulant medication.
An Electromagnetic Transducer?
Anybody that has experienced jet-lag once too often or who has had to work 3rd shift for an extended period of time is probably familiar with the effects of light on sleep patterns and the relevant, researched benefits involved in adjusting the sleep phase with melatonin. But less well-known is the potentially effects caused by night-time illumination. Since melatonin levels are tied to the amount of light sensed by the retina, high-intensity light after sunset can impact melatonin levels. Even low level light during our sleep periods can also affect our melatonin production.
Melatonin is produced biosynthetically from tryptophan and is one of the reasons that tryptophan can help promote sleep and relaxation. Vitamin B 6 is cofactor in this enzymatic pathway, including the process of tryptophan decarboxylation. Although melatonin is synthesized in the pineal gland, a small endocrine gland shaped like a pine-cone that is found between the hemispheres above the brain- stem in vertebrates, it is also produced in the retina, bone-marrow, gall bladder, and gastrointestinal tract.
Melatonin possesses significant direct antioxidant activity scavenging hydroxyl, peroxyl, singlet oxygen, and nitric oxide species. Yet it also stimulates the body’s own antioxidant and Phase I protection systems.
Melatonin’s cyclic changes track and impact other physiological cycles, such as cortisol levels and body temperature. Body temperature seems to be modulated by direct action on the hypothalamus. Action on the hypothalamus is also implicated in effects on the cardiovascular system and blood pressure seen with melatonin. Melatonin is also intimately involved with the immune response, inflammatory cascades, and the health of the intestinal tract.
Melatonin Sustain provides melatonin and a key cofactor (vitamin B 6 ) essential for the biosynthesis of melatonin. Due to an extremely short half-life in blood, melatonin that is released over time in the intestines supports sustained melatonin levels and helps avoid melatonin spikes.
Some supplements are suitable for both men and women of all ages as well as children. But other supplements are specifically targeted to the aging woman or man. Another supplement is especially suitable for athletes, regardless of gender.

Can you ever get used to working night shifts?Last Sunday the Daylight Saving Time ended, and if your reaction was similar to mine, it felt like we plunged right into the darkest time of year. Only a few days earlier, I'd be out and about in broad daylight to get your parcels delivered to you on time, then all of a sudden dusk had set in already.
Maybe your reaction was similar, or if you are someone who rises early, you're happy to see the sun back for a short while when waking up.
Or, perhaps you aren't seeing the sun much at all, because you belong to the almost 20% of people who habitually work at weird hours. Some of you may only work night shifts, while others will have rotating shifts.
For those of you, who may for one reason or another will have to work in shifts soon, we have gathered more background information on how shift work affects your life and how to adapt to it.
Almost everyone has hard time adapting to night shifts, but most people can adapt to it within a few months.
DHEA, what is it and why is it so popular?DHEA is an abbreviation for dehydroepiandrosterone, which is a steroid hormone available in dietary supplement form. Inside the body, it is made in the adrenal glands.
In the body, DHEA is converted into male and female sex hormones, such as estrogen and testosterone.
DHEA is also responsible for developing “androgenic effects” that are referred to as masculinization. Examples of such changes include production of oilier skin, changes in body odor and growth of armpit and pubic hair.
On the other hand, DHEA can play a part in physiological pathways, since it is believed to bind to certain receptor types and act as a neurosteroid that directly affects neuronal excitability.
DHEA production peaks around age 25. Afterwards DHEA levels decline steadily.
Misconceptions about drug abuse"Did you hear the news already? Rich Piana died last week!" exclaimed a good friend of ours. "Rich who??" was my response. Then it dawned on me he was speaking of the same person about whom I had been reading the other day and of which I only remembered his face and enormous physique.
Rich Piana, who had a large group of followers on Youtube and Instagram, as he had a most bizarre amount of muscles and was famous for his grueling workouts.
Almost immediately everyone assumed he probably died due to overuse of steroids and associated muscle-building products.
It is not so weird to assume this as the amount of bodybuilders, who haven't lived past 50 years is staggering, because of the ever more dangerous means of attaining a muscular physique that is bigger than that of other competitors in bodybuilding demand more lives every decade.
The burning desire to create even more muscle mass wins from common sense. When discussing his death people referred a very good documentary called:Bigger, Stronger and Faster. Yet, at a lower level, the sports of recreational bodybuilders, apparently is one of the safest sports around.
How to deal with sleeplessness
Sleep problems are as old as mankind, but it has become more problematic than ever with the advent of modern technology resulting in "poor sleep hygiene". Exposure to bright light late at night results in falling asleep too late and sleeping too little, because it disturbs the body clock that is regulated by melatonin.
