Trouble falling asleep and staying asleep is far from rare in Germany: around a third of Germans say they have sleep problems.
That's why 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. But melatonin can do so much more for your health.
We explain the benefits it 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.
There are countless melatonin products on the market, but not all of them are effective.
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 types of wine. Melatonin's main job is to regulate your sleep-wake cycle and promote sleep.
Often, though, it isn't enough to rely on your body's own production or to increase it through your diet. The causes vary: a melatonin deficiency, stress, jet lag, medication or other sleep problems, and the list goes on.
What's more, your body produces less and less melatonin as you get older, which is why many older people have trouble sleeping.
In 1990, researchers showed for the first time¹ that taking melatonin can shorten the early stages of sleep and lengthen REM sleep, which is so important for rest. Today we know that melatonin can do a great deal more.
Melatonin: an all-rounder for your 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: it doesn't just regulate your sleep-wake cycle, it also 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
If you take melatonin, there are a few things to look out for to make sure it works properly and is safe:
- the right dose: 1–3 mg, no more than 5 mg
- good bioavailability
- allergens, if you have allergies (lactose, gluten, soya)
- no unnecessary additives or fillers
- manufacturer information: sources, manufacturing processes, laboratory certificates
- no products of questionable quality
- no sugar, alcohol or flavourings
There are several things to consider when choosing the right melatonin supplement.
Dosage forms: how can you take melatonin?
Melatonin comes in a range of forms, so there's something for everyone. The most popular forms are:
- tablets and capsules
- sprays and drops
- gummies
- liposomal form
The choice mainly depends on your own preferences and needs. Bioavailability can differ, though, and liposomal capsules have proved the best option.
Sprays and drops can have the advantage of being absorbed faster under the tongue, so they start working sooner. Gummies, on the other hand, are particularly suitable for people who don't like swallowing tablets.
Capsules
Pros
Easy to swallow
Practical when travelling and on the go
Easy to dose (consistent active ingredient content)
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 for people with swallowing difficulties
A high dose may require 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 can taste unpleasant
Exact dosing can be difficult, as the number of drops varies
The liquid can leak or spill
Short shelf life
Liposomal form
Pros
Highest bioavailability of the active ingredient
Better absorption by bypassing stomach acid
Lower dose 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
Less choice, as not all manufacturers can use the method
Because they measure just nanometres across and have a fat-based structure, liposomes protect the melatonin inside them from being broken down by enzymes, such as those in saliva and stomach acid. They deliver the melatonin directly into the bloodstream, which significantly improves absorption.
Liposomal melatonin: why is it absorbed better?
Normal digestion can mean a large part of the melatonin is lost, so the amount you actually absorb is much lower than the dose you take. 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.
This works because the melatonin is encapsulated in liposomes (tiny lipid vesicles), which your body does not treat 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.
Simple model of a liposome with a fatty outer layer and a watery chamber inside. Liposomes are an innovative technology for releasing active ingredients efficiently, exactly where they're needed. As a result, they've earned a firm place in medicine and cosmetics and are known for their many uses.
More advantages: 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 around 2–3 hours.
Liposomal melatonin, on the other hand, is released gradually, so it can stay active in the bloodstream for up to 6–8 hours, which suits anyone who wants to sleep for longer.
Melatonin in liposomal form is also better tolerated. Regular melatonin can cause nausea or an upset stomach in around 12–15% of users. With their protective lipid coating, liposomal forms are said to reduce the likelihood of side effects like these.

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 much 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 linked to the ageing process.
Melatonin's antioxidant effect may help reduce oxidative stress and protect cells from damage, which in turn helps to counter ageing.Melatonin also helps fight inflammation and supports the function of the mitochondria and the immune system: all factors that play a role in ageing. On top of that, melatonin can support the production of other hormones, including growth hormone, which is essential for repairing and regenerating tissue.
Melatonin production tends to fall as you get older. This can leave your body less able to counter oxidative stress and protect itself from free radical damage. Your skin cells then 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: it doesn't just regulate your sleep-wake cycle, it also supports your general health in many ways.
Good for your immune system and your defences against illness
Melatonin naturally helps your immune system by promoting healthy sleep, which your body needs in order to recover. People who sleep badly are usually much more susceptible to all kinds of illness.
As you get older, though, your immune system gets weaker too. Melatonin counteracts this process, known as immunosenescence, by acting as an immune stimulant, partly thanks to its anti-inflammatory properties. It may therefore 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 have an opposing relationship: when melatonin levels are high, cortisol levels should be low, and vice versa. If either of them gets out of balance, 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
Incidentally, 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 lack of serotonin leads to sleep problems, such as depression or anxiety disorders. In a mouse model, giving melatonin also increased the release of serotonin.¹⁰
Our verdict: melatonin supports your body in many ways
You shouldn't take too much melatonin, and you shouldn't take it for long periods without talking to your doctor. But who would have guessed that, as well as helping you sleep, it could do so much for your health? Healthy sleep alone supports your body in many ways, and melatonin can also support your immune system and help fight inflammation and various diseases.
So melatonin really can benefit your health. Take a look at our top picks and find the product that's right for you.
