Description

PUR4 CALM GUT is a nutrient complex to support your gut. For optimal intestinal function, the intestinal tract requires a regular supply of certain nutrients such as amino acids, minerals, trace elements, and vitamins.

If the body is not supplied with enough of these substances, it can promote the development of irritable bowel syndrome or leaky gut syndrome.

To counteract these cases and to support their treatment, we have created PUR4 Gutsana.

The recipe of PUR4 Calm Gut is based on the latest scientific findings on intestinal health.

The includedL-GlutamineandL-Argininecan help to increase the integrity of the intestinal mucosa and reduce inflammatory processes in it. The containedPectin,thePsyllium husksandWheat germThey bind water, form a mucus layer, and increase stool volume. This can provide additional protection for the intestinal mucosa against pathogens and accelerate intestinal transit. As prebiotics, they also support the health of the intestinal microbiome.

By adding minerals such aszincandseleniumand vitaminsA, D, K,andall B vitaminsEnergy metabolism, cell division, the nervous system and the mucous membranes are additionally supported.

"Many people underestimate how closely intestinal health is linked to skin condition. I use PUR4 CALM GUT especially when my skin is sensitive, irritated, or stressed.
Through the targeted regulation of inflammatory processes in the intestines and the strengthening of the mucous membranes, the skin can often be visibly soothed from within – holistically, sustainably, and effectively."

FAQs about our dietary supplements for the intestines

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.
