How to take
2 capsules with water, in the evening, about 30 minutes before bedtime. Every evening at the same time. The beneficial effect of melatonin is obtained with a daily intake of 1mg shortly before bedtime. The 60-capsule pack is enough for 30 nights.
When is it felt
Melatonin works from the very first night. It is the signal to the brain to fall asleep. Rhythm comes with repetition, so take it for about 30 evenings at the same time. Three packs are a realistic timeframe to build a lasting effect on falling asleep.
Will it make me drowsy in the morning?
No. That is why the dose is 1 mg, not 5. The low dose supports the body's own signal instead of replacing it. In a study, the physiological dose restored sleep, while the higher one left melatonin elevated until morning. Sleep 8 is not a sleeping pill, but a dietary supplement.
Who is it suitable for
For adults who find it difficult to fall asleep because their brain is active the moment their head hits the pillow. If you have sleep problems, this is perfect for you. Not suitable for pregnant or breastfeeding women or children. If you are undergoing medical treatment, please see the "Can I take this with my therapy?" section below.

the night you know the night we aim for
We know this scenario
You are tired all day long. But as soon as you lie down, you cannot fall asleep.
Your head hits the pillow and it begins: what you didn't finish, what you need to say tomorrow, that conversation from a week ago. You reach for your phone "just for a second." When you put it down, it’s already 1:40 AM. The morning is hard and you wake up exhausted. Gradually, you start telling yourself: "that’s just the way I am, I'm naturally high-strung."
You are not. This is sleep deprivation that has turned into a problem.
Irritability, afternoon brain fog, evening sugar cravings... a large part of what we attribute to character or age is simply a lack of sound sleep that has accumulated over time.
The body has its own sleep signal, and that is melatonin. It begins to be released when it gets dark. Its role is to tell the brain that the day is over. Screens, light in the evening, late-night eating, and stress delay it. Sleep 8 provides this signal in the precise dose - 1 mg, shortly before bedtime. It is precisely for this dose that the European Union allows the claim that melatonin contributes to reducing the time taken to fall asleep.
Eight hours of sleep determine the remaining sixteen. When should you go to bed?
The schedule is a guide for a routine, not medical advice. The most important thing is that the time is the same every night — including on weekends.
Your evening for eight hours of sleep
—Screens aside, lights dimmed
—2 Sleep 8 capsules with a little water
—In bed, the lamp turned off
—The alarm clock — after eight hours of sleep
Melatonin is taken about 30 minutes before bedtime: the beneficial effect is obtained with a daily intake of 1 mg shortly before bedtime.

One milligram of Melatonin.
Melatonin is a signal to the body, not a sleeping pill.
On pharmacy shelves, you will see melatonin in doses of 3, 5, or more milligrams. The "more is stronger" logic does not apply here. Melatonin does not force you to sleep; it tells your brain that the day is over. The signal needs to be clear, not strong.
"Melatonin contributes to the reduction of time taken to fall asleep." The beneficial effect is obtained with a daily intake of 1 mg of melatonin shortly before bedtime.
This is the officially authorized health claim in the EU under Regulation (EU) No 432/2012, for which the condition is exactly 1 mg. Sleep 8 is formulated exactly to this standard. The low dose supports the body's own signal instead of replacing it, which is also the answer to the question "will I get used to it?"

Sleep 8 is a dietary supplement, not a medicine, and does not replace prescribed treatment. In case of persistent insomnia, pregnancy, breastfeeding, medication use, or for children, consult a doctor.
What to expect and when
The first night is the signal. The thirtieth is the habit.
Melatonin works from the very first night. But sleep is a rhythm, and a rhythm is built through repetition at the same hour, night after night. Here is what usually happens
Evening 1 · The signal
Melatonin works that very same evening. It is a signal, not a cumulative effect. 2 capsules about 30 minutes before bed, then you turn off the light, put your phone aside, and fall asleep. Do not expect a "hit" of sleepiness; expect your brain to relax more easily and for you to fall asleep.
Tip: use the calculator above and set a reminder on your phone for the capsule times.
Before ordering
"Can I take it with my current therapy?"
Melatonin is a substance that your body produces on its own, and 1 mg is a low dose. For most people, there is no problem at all. However, there is a short list of medications and conditions for which we honestly say "no" or "ask your doctor first," and we prefer that you read it here rather than find out for yourself.
✓
Any healthy adult who finds it hard to fall asleepYou can take it with peace of mind — this is exactly what it is made for. 2 capsules about 30 minutes before bed.
✓

✓
Travelling across time zonesMelatonin also has an authorised claim for this: it contributes to the alleviation of subjective feelings of jet lag, when taken shortly before bed on the first day of travel and for a few days after arrival.
✓
If you drink coffee during the dayYes. We would advise having your last coffee before 16:00. Caffeine in the evening works against the evening signal for falling asleep.
✓
Night shift workYes — take Sleep 8 only before your main sleep, whatever time that is. Take the supplement at home, before you get ready for sleep.

The studies focus on the individual ingredients and the dosages used in scientific settings, rather than on the finished product. The only sleep-related claim that Sleep 8 makes is the authorized one: melatonin contributes to the reduction of time taken to fall asleep.
"How do you sleep?" — why I created Sleep 8
"How are you sleeping?"—this is the first question I ask when someone tells me about headaches, exhaustion, or lack of focus.
Dr. Nedelya Shtonova
neurologist
I have read over 25,000 of your comments. In a huge number of them, under products for memory, menopause, or blood sugar, someone "by the way" adds a line about their nights. Almost no one talks about sleep as a problem, yet it is the foundation of health and the best healer. As a neurologist, I do not see it as a trifle to be dealt with incidentally, but as the foundation upon which everything else stands. Sleep 8 is the formula I have been working on the longest, from the very beginning of the brand. Sleep is not the end of the day, but the beginning of the next one. Value it.
What people who tried it are sharing:
Frequently Asked Questions
Is Sleep 8 a sleeping pill?
No. A sleeping pill is a medication that suppresses the nervous system. Sleep 8 is a dietary supplement containing melatonin—a substance your body produces on its own to signal that the day is over. The authorized claim is single and precise: melatonin contributes to the reduction of time taken to fall asleep.
How is it taken?
2 capsules with a little water, in the evening, about 30 minutes before bedtime. Every evening at the same time - this is half the effect. The beneficial effect is obtained with a daily intake of 1 mg of melatonin shortly before bedtime.
How many capsules are in the package?
60 capsules that will last you for 30 nights. Two packs are for 60 nights, three packs for 90, the realistic timeframe to feel a lasting improvement in your sleep with Sleep 8.
When will I feel the effect?
Melatonin works from the very first night. The rhythm is built through repetition — at least 30 nights at the same time. The sensations are individual.
Will I be sleepy in the morning? Will I get used to it?
That is exactly why the dose is 1 mg, not 5. The low dose supports the body's own signal instead of replacing it. In a study, the physiological dose restored sleep, while a dose ten times higher left melatonin levels elevated until morning. Sleep 8 is not a sleeping pill and does not create dependency like one.
Why only 1 mg, when there are 5 mg versions on the market?
Because melatonin is a signal, not a strength. 1 mg is exactly the dose for which the European Union authorizes the claim of falling asleep faster. More does not mean better — higher doses more often leave you feeling sleepy in the morning.
Can I take it with medication?
It depends on the medication. That is why the decision rests with your attending physician. In the "Can I take this with my therapy?" section, we have honestly described what is safe, what requires a doctor, and what we do not recommend. Message us privately with the word "composition," and we will send you the formula in a readable format for your check-up.
Can I combine it with the other Sapphire products?
Yes, you can combine it with Menoflor 6, Focus 7, Gluco 1, and Microbiome 11, provided that the daily dosages are followed. Sleep 8 is taken in the evening, 30 minutes before bedtime.
For whom is it not suitable?
For pregnant or breastfeeding women and children. Do not take before driving or operating machinery. This food supplement is not a solution for chronic insomnia caused by a medical condition such as thyroid issues, sleep apnea, anxiety, or depression. These require consultation with a doctor.
What if it doesn't work for me?
Sleep depends on many things - bedtime, light, screens, afternoon coffee. If after the first month you would like us to review your intake together, write to us or call 02 408 5577. And if you have been waking up at night for months on end, this also warrants a check-up with a doctor.
Is it really Dr. Shtonova's?
Yes. This is Sapphire's official store; the formulas are her own, and Sleep 8 is the formula she has been working on for the longest time, since the very beginning of the brand.
Where can I buy it in person?
In addition to online, you can find our products at Subra pharmacies, 36.6 Pharmacies, Nove, and in dm drugstores.
Eight hours of sleep determine the other sixteen.
