Weniger Blähbauch, mehr Balance

Ich bin bei Supplements eher kritisch, weil ich bei vielem keinen großen Unterschied merke. Das MICROBIOME BUNDLE hat mich aber positiv überrascht. Meine Verdauung fühlt sich deutlich ruhiger und ausgeglichener an und ich habe insgesamt einfach ein besseres Bauchgefühl. Kein Wundermittel, aber eines der wenigen Produkte, bei denen ich wirklich das Gefühl habe, dass es etwas bringt.

Absolute Empfehlung- Spürbare Wirkung

Ich bin wirklich beeindruckt von den Immun Kapseln von Pur 4. Für mich sind sie mittlerweile fester Bestandteil meiner Hausapotheke. Immer wenn ich die ersten Symptome einer Verkühlung, Grippe oder allgemeiner Schwäche gespürt habe, habe ich eine Kur damit gestartet – und was soll ich sagen: Wo ich früher garantiert krank geworden wäre, konnte ich diesmal das Krankwerden komplett abwehren.

Die Wirkung hat mich so überzeugt, dass ich sicher bin, dass hier wirklich hochwertige Inhaltsstoffe drinstecken. Für mich sind die Kapseln der absolute Hammer und eine klare Empfehlung für alle, die ihr Immunsystem zuverlässig unterstützen wollen.

FAQs about our Nutritional supplements for sleep

What are the benefits of sleep supplements?

Restful sleep isn't a luxury—it's the foundation for energy, regeneration, and emotional stability. When your natural sleep rhythm gets out of sync, specially developed nutritional supplements like PUR4 SLEEP can help gently restore balance to your body and mind.

The advantages at a glance:

– Promotes falling asleep and staying asleep: Ingredients such as GABA, L-theanine or L-glutamine can regulate activity in the nervous system and thus help you to relax more quickly.

– Reduction of stress, restlessness and brooding: Adaptogenic plant substances such as valerian, passionflower or lemon balm support emotional relaxation – without any potential for addiction.

– Supports the body's own melatonin production: Co-factors such as magnesium, vitamins B6 and B12 help your body to naturally produce the sleep hormone melatonin – for a healthy day-night rhythm.

– Improved sleep quality: Many users report deeper, more restful sleep and a clearer head the next morning.

Which ingredients are particularly important in sleep supplements?

Effective sleep supplements like PUR4 SLEEP rely on ingredients that specifically calm the nervous system, support the body's own melatonin production, and gently regulate the natural day-night rhythm – without addiction or a tired hangover in the morning.

Particularly relevant ingredients are:

GABA (gamma-aminobutyric acid)
The brain's most important calming neurotransmitter, GABA helps reduce inner restlessness, slow the flow of thoughts, and facilitate sleep.

L-Theanine
An amino acid from green tea that can enhance the effects of GABA. It supports the development of alpha brain waves—typical of deep relaxation and mental calm.

L-Glutamine
The precursor to GABA. In combination with L-arginine, it can help noticeably increase GABA levels in the brain—for more calm at the neuronal level.

Magnesium, vitamins B6 and B12
These micronutrients promote the conversion of glutamine into GABA and are also essential for the production of melatonin – your body’s sleep hormone.

Plant extracts such as valerian, passionflower and lemon balm
Traditionally proven to promote inner peace, relaxation, and sleep quality. They have a calming, anxiety-relieving effect and help you switch off from nighttime worries.

Are there any side effects of taking sleep supplements?

We're not aware of any side effects associated with PUR4 SLEEP, provided you follow the recommended dosage, of course.

How long does it take for sleep supplements to take effect?

PUR4 SLEEP is designed so that the effect can begin after just a few doses.

Can sleep supplements help with insomnia?

Yes, PUR4 SLEEP can help with insomnia. However, the extent to which it can help depends on the cause of your insomnia. What PUR4 SLEEP cannot do, however, is eliminate the causes of your insomnia.

Can sleep supplements also reduce stress?

Yes – and that’s exactly what makes PUR4 SLEEP so special: It not only helps you fall asleep and sleep through the night, but also helps you wind down emotionally and physically when your day is still echoing.

The combination of GABA, L-theanine, L-glutamine, and L-arginine has a targeted effect on the central nervous system. GABA is key: As a calming neurotransmitter, it helps to stop the carousel of thoughts and reduce neuronal activity—a key lever for stress-related sleeplessness. In combination with L-theanine, the effect in the brain can be enhanced and sustainably stabilized.

Magnesium, vitamin B6 and vitamin B12 not only support natural GABA production, but also your stress metabolism – for example by regulating cortisol and promoting melatonin synthesis.

The recipe is complemented by valerian, passionflower and lemon balm – traditionally proven plant substances that gently calm the organism without causing drowsiness or addiction.

PUR4 SLEEP has a holistic effect against stress: It helps you to let go internally, switch off mentally and give your body the impulse to regenerate – for noticeably better sleep and a clear head in the morning.

Are sleep supplements also recommended for older people?

Absolutely. Healthy, restful sleep is essential, even for older people. PUR4 SLEEP can help with just that, and is therefore also recommended for older people.

When should SLEEP be taken?

Take 1-2 capsules daily with 200ml of water before going to bed for at least 3 months.
