Iberogast 50 ml

Regular price $22.90


Made in Germany and used throughout Europe and other parts of the world for more than forty years, Iberogast came to Canada in 2006. Of the estimated 20,000,000 patients using Iberogast, only 18 reported adverse events over the years.

Iberogast® harnesses the power of nine natural plant extracts to effectively relieve multiple symptoms fast. It targets4:

  • Abdominal pains and cramps
  • Fullness
  • Heaviness
  • Heartburn & acid reflux
  • Bloating
  • Flatulence
  • Nausea
  • Constipation

Dyspepsia and IBS often have multiple underlying functional causes and this product, containing nine active ingredients, affects various functional mechanisms to alleviate several underlying factors in a complimentary, synergistic way.6,7 It contains no sugar, salt, yeast, wheat, gluten, corn, soy, dairy products, artificial colouring, artificial flavouring, or preservatives. It contains a small amount of alcohol. The components in this product, shown across the bottom of these pages, work together facilitating a number of digestive improvements such as:

  • Regulation of peristalsis – by relieving or preventing intestinal spasms and by strengthening, coordinating, and toning the smooth muscles within the digestive tract.8 This happens when the stomach’s upper area relaxes while the lower area, where the food passes to the intestines, is toned.9
  • Reduces acid production and improves digestive secretions, by positively affecting the mucous membranes of the stomach and the intestines.8 When the product interacts with the bitter receptors in the taste buds on the tongue, this stimulates digestive secretions.
  • Carminative – this means that the product helps induces the expulsion of gas from the stomach and intestines.8 It also helps reduce gas formation.
  • Local anaesthetic – the product elicits mild pain relief by numbing some areas within the digestive tract.8Patients with functional GI ailments often have an increased sensitivity to pain. It is difficult to know how much of this effect is truly due to reducing the sensitivity of nerve endings, since most of the pain receptors in the gut are within the nerve plexuses in the muscle layers, and not in the mucosa, or inner lining layer.
  • Free radical scavenging properties of this product help with possible digestive inflammation cascades from certain foods, which release free radicals in the gastrointestinal tract triggering inflammation and related dyspepsia.
  • Antibacterial – the constituent components of STW 5 inhibit the growth of six subspecies of Helicobacter pylori, a bacterium that frequently infects the stomach. However, the role of Helicobacter pylori in causing FD is probably minimal if anything, in most patients.
  • Dyspepsia-specific Research A recent study found that FD patients taking Iberogast had significantly reduced gastrointestinal symptoms compared to the control group who were taking placebo. Of patients taking Iberogast, 86% reported a therapeutic effect after four weeks of treatment.10 Results from a meta-analysis, which combined data from multiple, varied, small trials performed over the past decade, reinforce these findings of significantly more effectiveness than placebo in providing symptomatic relief to patients with FD. This seems even more evident with associated symptoms of gastroesophageal reflux (GERD) or predominance of upper GI pain. The researchers compiling the data agreed that although the cumulative total of patients in this meta-analysis was relatively limited, it was still large enough to demonstrate efficacy, even though they suggest more research.11 Another trial showed statistically equivalent efficacy in treating gastrointestinal symptoms to the now unavailable prokinetic (motility stimulant) agent, cisapride (Prepulsid®).12
  • IBS-specific Research A four-week study involving 208 patients with IBS in 2004 showed Iberogast as significantly better than placebo in reducing both the total abdominal pain score and IBS symptom score. On average, patients found Iberogast to treat some symptoms 20% better than placebo, and the proportion of patients with complete relief was more than 50% greater than placebo.13 By acting on two different serotonin receptors in the gut, positive results with Iberogast were for patients who had predominant symptoms of diarrhea, constipation, and altering stool consistencies.14

Pregnancy and Lactation

The use of Iberogast® during pregnancy and lactation has not been fully studied and it should only be used in these circumstances under the guidance of a healthcare professional.


Even though Iberogast derives from plants, with its efficacy in the area of functional gastrointestinal ailments, clinically confirmed by long-term traditional use and pharmacological investigations, it belongs with the evidence-based pharmaceutical products. It is worth a try if you have non-ulcer dyspepsia or irritable bowel syndrome. You just might find relief.
