Do you often wake up at night and struggle to get back to sleep? Conventional melatonin often only helps you fall asleep, because it breaks down too quickly. The key to an undisturbed night's sleep is prolonged-release melatonin.
It's no surprise, then, that more and more people are turning to melatonin: the sleep hormone is considered well tolerated and, unlike prescription sleeping pills, it isn't habit-forming. The key advantage: gradual release (the prolonged-release effect) keeps your melatonin levels steady all night.
Below, we explain the benefits melatonin can offer, how to take it and what to look for when you buy. You'll also find a detailed review of the best melatonin products to help you choose.
Many melatonin products don't work for long enough: only a prolonged-release formula helps you sleep through the whole night.
Melatonin: essential for restful sleep
Melatonin is a hormone your body makes itself in the pineal gland (in the diencephalon). It's also found in very small amounts in certain foods, such as cranberries, milk, some mushrooms and cereals, pistachios and some wines. Melatonin's main job is to regulate your body clock and promote sleep.
Often, though, relying on your body's own production, or increasing it through your diet, isn't enough. The reasons are many, from a melatonin deficiency, stress and jet lag to medication and other sleep problems.
What's more, your body produces less and less melatonin as you get older, which is why many older people struggle with sleep problems.
In 1990 it was discovered for the first time¹ that taking melatonin can shorten the early stages of sleep and lengthen the important REM sleep. Today we know that melatonin can do a great deal more.
Melatonin: the all-rounder for health
Most people have heard by now that melatonin can help with sleep problems. But the hormone can do much more for your health: it's considered an antioxidant that reduces oxidative stress, supports the immune system and has an anti-inflammatory effect.
Taking melatonin is also said to help with muscle and nerve conditions.⁴,⁵
Melatonin is a versatile hormone: as well as regulating the sleep-wake cycle, it supports your general health in many ways.

Not all melatonin is the same: what to look for when you buy
Things to bear in mind
When you take melatonin, there are a few things to check to make sure it works properly and is safe:
- the right dose: 1–3 mg, 5 mg at most
- good bioavailability
- allergens, if you have allergies (lactose, gluten, soya)
- no unnecessary additives or fillers
- information from the manufacturer: sources, manufacturing processes, laboratory certificates
- no products of questionable quality
- no sugar, alcohol or flavourings
There are several factors to consider when you choose the right melatonin supplement.
Dosage forms: how can you take melatonin?
Melatonin comes in several forms, so there's something for everyone. The most popular forms are:
- tablets/capsules
- sprays and drops
- gummies
- liposomal form
The choice mainly depends on your own preferences and needs. There can be differences in bioavailability, though, and liposomal capsules have proved the best option.
Sprays and drops can have the advantage of being absorbed faster under the tongue, so the effect kicks in sooner. Gummies, on the other hand, are especially suitable if you don't like swallowing tablets.
Capsules
Pros
Easy to take: you just swallow them
Practical on the go and when travelling
Easy to dose (each capsule contains the same amount of active ingredient)
No unpleasant taste or smell
Can be combined with other active ingredients
Cons
Stomach acid can affect absorption of the active ingredient
Digestion can partly break down the active ingredient
The bioavailability of the active ingredient can vary
The capsule shell may contain gelatine
Often contain additives
Unsuitable if you have difficulty swallowing
A high dose may mean taking several capsules
Drops
Pros
Easy to dose
Fast absorption of the active ingredient (via the mucous membranes)
Good for people with swallowing difficulties or stomach problems
Versatile: can be mixed into drinks or food
Cons
The drops may taste unpleasant
Exact dosing can be tricky, as drop size can vary
The liquid can leak or spill
Short shelf life
Liposomal form
Pros
Highest bioavailability of the active ingredient
Better absorption because stomach acid is bypassed
A lower dose is needed for the same effect
Can mask the taste of the active ingredient
No additives
Cons
May cost more because manufacturing is more complex
Availability and choice may be limited
Producing liposomes can be difficult and requires specialised technology
Not every manufacturer has the technology to make them
Because they're just nanometres across and made of fats (lipids), liposomes protect the melatonin inside them from being broken down by enzymes, saliva and stomach acid. They allow the melatonin to be delivered directly into the bloodstream, which significantly improves its absorption.
Liposomal melatonin: why is it absorbed better?
During normal digestion, a large share of the melatonin can be lost, so the dose you actually get is much lower. Depending on the study, the bioavailability of conventional melatonin is only 15–30%.
Taking melatonin in liposomal form improves your body's ability to absorb it.
Here's how it works: the liposomes (tiny lipid vesicles) are built in such a way that your body doesn't treat them as foreign. Liposomes are also found in your cell membranes. They protect the melatonin from the acidic environment of the stomach and allow it to be absorbed directly into the cells. This makes it considerably more effective.
A simple model of a liposome, with a layer of fat on the outside and a watery chamber inside. Liposomes are an innovative technology for releasing active ingredients precisely and efficiently. That's why they're now widely used in medicine and cosmetics.
More benefits: a longer-lasting effect and better tolerability
Conventional melatonin usually reaches its peak concentration in the blood within 30–60 minutes, and the effect lasts for around 2–3 hours.
Liposomal melatonin, by contrast, releases its active ingredient gradually and can stay active in the bloodstream for up to 6–8 hours, which makes it a better fit if you want to sleep for longer.Liposomal melatonin is also better tolerated. Conventional melatonin can cause nausea or an upset stomach in around 12–15% of users. Thanks to their protective lipid coating, liposomal forms are said to make side effects like these less likely.

This means you need to take less, yet it works better.
While conventional supplements often leave a 'gap' in their effect in the middle of the night, Melinava provides a continuous release over 6–8 hours. This prevents the night-time waking so many people know and ensures restorative deep sleep.
Unlike conventional prolonged-release tablets, Melinava uses liposomal encapsulation to release the melatonin gradually and gently, without putting a strain on your digestion.
Melinava's products are formulated to be highly effective and use 100% pure ingredients of the highest quality. This is also reflected in the positive reviews from customers.
With Melinava Melatonin, you simply take one capsule around 30–60 minutes before going to bed.

One pack contains 120 capsules.
Did you know that melatonin even has an anti-ageing effect on the body?
Its antioxidant properties counteract the ageing process⁶
In fact, melatonin can do far more than help you fall asleep. It has strong antioxidant properties and acts as a scavenger of highly reactive molecules known as free radicals. Free radicals are known to cause oxidative damage, which is associated with the ageing process.
Melatonin's antioxidant effect can help reduce oxidative stress and protect cells from damage, which helps slow the ageing process.
Melatonin also helps fight inflammation and supports the function of the mitochondria and the immune system, all factors that play a role in ageing. And there's more: melatonin can also support the production of other hormones, including growth hormone, which is essential for repairing and regenerating tissue.
Melatonin production tends to decline with age. This can leave your body less able to counter oxidative stress and protect itself from free-radical damage. As a result, skin cells become more vulnerable to damage from environmental factors such as UV radiation from the sun, pollution and other sources of oxidative stress. This speeds up skin ageing, including the formation of wrinkles.
Melatonin is a versatile hormone: as well as regulating the sleep-wake cycle, it supports your general health in many ways.
Benefits for the immune system and in the fight against disease
Firstly, melatonin helps the immune system by promoting healthy sleep, which your body needs to recover. People who sleep badly are usually much more susceptible to illness.
As you get older, your immune system also becomes weaker. Melatonin counteracts this decline, known as immunosenescence, by acting as an immune stimulant, partly through its anti-inflammatory properties. This means it can help strengthen the antibody response, reduce chronic inflammation and stimulate T cells to fight pathogens.
The sleep hormone melatonin vs the stress hormone cortisol
Melatonin and the stress hormone cortisol work in opposition to each other: when melatonin levels are high, cortisol levels should be low, and vice versa. If the balance between them is upset, your sleep suffers. The closer it gets to morning, the more cortisol your body makes and the less melatonin it produces. When you go to bed, it should be exactly the other way round. But if you're stressed, exercise late in the evening or have caffeine, your cortisol levels can rise and disrupt your sleep.⁹
Melatonin is also directly linked to the 'happy hormone' serotonin: the pineal gland converts serotonin into melatonin. That's why the sleep hormone can also help with conditions in which a serotonin deficiency leads to sleep problems, such as depression or anxiety disorders. In a mouse model, melatonin supplementation also increased serotonin release.¹⁰
Our verdict: melatonin supports your body in many ways
You shouldn't take too much melatonin, though, or take it over a long period without talking to your doctor. But would you have thought that, besides helping you sleep, it has so many positive effects on your health? Healthy sleep alone does your body a great deal of good, but melatonin can also support your immune system and help fight inflammation and various diseases.
