Enjoy our initial prices! Melatonin can help reduce the time that it takes to fall asleep (sleep onset latency). We think that 0.8 mg of melatonin is the perfect dose of melatonin for most adults. Under normal circumstances, melatonin is present in our body during the night and should be out of our system in the morning. Taking a lower dose reduces the likelihood of having high melatonin levels in the morning when the normal levels of this hormone tend to be zero, or undetectable. The total production of melatonin in adults is usually very low and has been estimated between 10 and 80 micro-grams (1000 micro grams= 1 milligram) so 0.8 mg IS enough.
When it comes to melatonin, the dose and the timing are very important, and "more" is not necessarily better.
Take only 1capsule 2 to 4 hoursprior to usual bedtime.

Melatonin is produced by the pineal gland in response to darkness. It is one of the most important messengers of the circadian system and the sleep-and-wake cycle in humans. Melatonin, and the circadian system, play an important role in the initiation of sleep, in the maintenance of sleep, and in many other body functions.
The exact mechanisms that control the production of melatonin are not completely understood but blue/green light is known to suppress the natural production of melatonin and can alter the circadian system. Blue/green light is sensed by specialized cells in our eyes that are called Retinal Ganglion cells.
In human beings, the pineal gland starts producing melatonin 2 to 3 hours prior to usual bedtime, hence the importance of taking this supplement before our usual bedtime for better results. Melatonin, can help reduce the time that it takes to fall asleep.
There may be a risk of allergic reactions to melatonin supplements.
There’s been a lack of research on the safety of melatonin use in pregnant or breastfeeding women
The possible long-term side effects of melatonin use are unclear.
As with all dietary supplements, people who are taking medications should consult their doctors before using any supplements. People with epilepsy, taking sedative medications, and those taking blood thinner medications need close medical supervision when taking melatonin supplements.
Improve your sleep quality by protecting the natural production of melatonin, blue light blocking glasses are proven to reduce the time that it takes to fall asleep. Wave goodbye to tossing, turning, and struggling to drift off. Scientific studies have shown that amber-colored blue light blocking glasses can improve sleep quality during the night and then improve alertness the following day.
Our blue light glasses are ideal for people who want to improve their sleep quality; you should use them while working late on a computer, watching TV before bedtime, or when exposed to excessive illumination in the evening.
Why should you buy sleep products from Keldik? Because you should only entrust your sleep needs to the best-qualified experts. Our company is led by a Board Certified Sleep Medicine Specialist and we know a thing or two about sleep.
Our blue- light blocking glasses are specifically designed for sleep and for the circadian system (aka: our internal clock). Why does blue light impact sleep so much? Melatonin is a hormone naturally produced by the body that influences sleep, and exposure to blue light suppresses the production of this much-needed hormone, leading to unsettled sleep followed by reduced alertness and fatigue the next day.
Any light can affect the production of melatonin and affect sleep but blue light does so more powerfully. Blue light is present in screens, TVS, and LED lights. Blue light activates a retinal pigment called Melanopsin and this can block the natural production of melatonin in the evening.
On average, we spend up to 7 hours a day in front of screens that will negatively impact our sleep, and the problem becomes worse if you’re using these devices in the hours before sleeping. The lenses found in our blue light blocking glasses for sleep are amber-tinted and engineered to deflect the maximum amount of blue light.
Lightweight, stylish, and seriously comfortable, the black-rimmed rectangle finish is a classically versatile design that will fit most faces and is gender neutral.
