Let customers speak for us
from 125 reviewsIch 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.
Ich nutze Brain Focus mittlerweile regelmäßig und merke vor allem einen Unterschied bei meiner Konzentrationsfähigkeit!
Gerade in stressigen Phasen hilft es mir, konzentrierter und strukturierter zu arbeiten.
Ein super Supplement für alle, die im Alltag, Studium oder Beruf mental viel leisten müssen :)
Brain Focus hat mir endlich ermöglich mich so zu konzentrieren wie früher. Ich bin bei der Arbeit viel fokussierter und kann Aufgaben viel effizienter abarbeiten ohne dass meine Gedanken ständig abweichen.
Ich spüre wirklich einen Unterschied nach 3 Wochen Einnahme und bin leistungsfähiger beim Joggen und irgendwie generell konzentrierter. So machen Supplements Spaß!
Nehme den Longevity Booster seit fast einem Jahr jeden Tag, und merke deutlich, dass ich mehr Energie habe. Meine Konzentration hat sich auch deutlich gebessert. Empfehle es auch hier im Raum Stuttgart allen meinen Freunden weiter. Hoffentlich macht ihr hier auch bald einmal eine Klinik auf!
Mito Power, erfüllt den Anspruch den ich an dieses Produkt habe!!!
Mit deutlicher Konzentration und Elan den Tag gestalten.
Auch ist die Kommunikation mit anderen Personen gestiegen, auch kann ich deutlich meine Grenzen wahrnehmen. Super
Morgens voller Energie in den Tag starten und abends entspannt zur Ruhe kommen, um erholsam durchzuschlafen – genau das macht PUR4 lebenswert
Hat bei mir innerhalb weniger Tage zu schnellerem einschlafen aber vor allem einer relaxteren Nachtruhe verholfen. Sehr gutes Produkt
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.
Seit ich Immune Recharge nehme, fühle ich mich fitter im Alltag und habe weniger Probleme mit Erkältungen.
Das erste Mal seit 20 Jahren ist meine Tagesmüdigkeit weg. Ich bin wirklich begeistert ein ganz hervorragendes Präparat Dorian Hartmuth aus Ober-Ramstadt.
Detox ohne Crash: normal essen, nur bewusster. Kein Durchfall, keine Krämpfe.
Nach ~3 Wochen weniger Unreinheiten. Kombiniert mit Schlaf & viel Grünzeug top.
Dunkles Zimmer, Handy weg, SLEEP – die Kombi wirkt.

FAQs about our Longevity Supplement
How do dietary supplements like PUR4 CALM GUT affect the intestines and digestion?
PUR4 CALM GUT was developed to specifically soothe an irritated and overactive intestine – especially in cases of functional complaints such as irritable bowel syndrome.
The formula combines high doses of L-glutamine and L-arginine, two amino acids that play an important role in the development and protection of the intestinal mucosa. They help strengthen the integrity of the intestinal wall and regulate inflammatory processes that often accompany an irritated gut.
Pectin, psyllium husks, and wheat germ act as prebiotic fibers that bind water, increase stool volume, and simultaneously build a protective mucus layer in the intestines—this can harmonize intestinal motility and reduce contact with irritating substances.
In addition, there are essential micronutrients such as zinc, selenium, as well as vitamins A, D, K and the complete B vitamin complex, which, among other things, strengthen the immune system, mucous membranes and energy metabolism - precisely the systems that often become unbalanced when the digestive tract is overtaxed.
PUR4 CALM GUT offers smart, holistic support for everyone who wants more peace of mind – evidence-based, functional and sustainable.
Are there any side effects when taking intestinal supplements?
To our knowledge, taking PUR4 CALM GUT is not associated with any side effects as long as you follow the recommended dosage.
How long does it take for CALM GUT to work?
PUR4 CALM GUT was developed to specifically soothe sensitive, irritated intestines and regenerate the mucous membranes. How quickly you feel an effect depends on your individual condition—for example, how stressed your intestines already are or how consistently you take it.
Many users report a more relaxed feeling in their stomach after just a few weeks – for example, due to less bloating, smoother digestion or less pressure.
The more profound effects – such as the rebuilding of the intestinal mucosa, the regulation of inflammation and a lasting calming of the digestive system – develop after at least 3 months.
How do PUR4 CALM GUT and PUR4 BELLY BOOST differ?
PUR4 BELLY BOOST is your go-to if you want to specifically build up your intestinal flora and strengthen your intestinal barrier. The combination of 40 billion active bacteria, prebiotic fiber like acacia fiber, and anti-inflammatory botanicals like myrrh and L-arginine supports the colonization of beneficial intestinal bacteria, stabilizes the mucous membrane, and ensures a resilient intestinal environment – ideal after antibiotics, in cases of microbiome imbalance, or for preventative purposes.
PUR4 CALM GUT, on the other hand, focuses on rest and regeneration for an over-stimulated gut. The formula is specifically designed to support irritable bowel symptoms: with botanicals such as chamomile, peppermint, turmeric, and lemon balm, which have antispasmodic, carminative, and calming effects. Additionally, targeted micronutrients contribute to relaxing the nervous system – for more balance in the stomach.
In short:
- BELLY BOOST = building, stability, microbiome
- CALM GUT = Calming, relaxation, irritable bowel care
How should CALM GUT be taken?
Take 2 capsules daily with 200ml of water with a meal or between meals with a little oil for at least 3 months.
How can CALM GUT support immune function?
The gut is home to around 80 percent of the body's immune cells. It stands to reason that dietary supplements that promote gut health can play a major role in supporting immune function. This also applies to PUR4 CALM GUT.
