Independent, primary-sourced research on gut health and the microbiome — probiotics, fibre and digestive supplements graded by the actual strength of the evidence.
Key takeaways Inulin is a fermentable fiber. Its source, chain-length distribution and accompanying ingredients matter A specific native chicory inulin preparation has an EU-authorized claim for increased stool frequency at 12 g/day. This is a defined food claim, not approval to treat every cause of constipation Several positive bowel trials were funded by ingredient makers. … Read more
Key takeaways Bromelain is a pineapple-derived mixture of protein-cutting enzymes. Enzyme activity is real; reliable relief of everyday bloating or indigestion from a standalone supplement is not independently established A recent human ulcerative-colitis trial deserves attention, but its funding and product-supply terms remain incompletely disclosed. It is preliminary evidence, not a reason to replace treatment … Read more
Key takeaways Papain can cut proteins. A meaningful digestive benefit from swallowing isolated papain has not been independently established Papaya fruit, fermented papaya, Caricol, Caricol-Gastro and multi-enzyme products are different interventions. Their results cannot be assigned to papain The better-known digestive studies have formulation, funding or design problems. Manufacturer involvement includes donated study products, not … Read more
Key takeaways PHGG is a soluble, low-viscosity fiber made by breaking down guar gum; intact guar gum is a different preparation Some human studies report better bowel symptoms, but much of the relevant research has manufacturer funding, commercial authors or donated products Under a strict independent-evidence standard, reliable benefit for IBS, constipation or diarrhea is … Read more
Key takeaways Prescription pancreatic enzyme replacement therapy, or PERT, has an established place in care for diagnosed exocrine pancreatic insufficiency That medical role does not establish that an over-the-counter pancreatin product improves ordinary bloating or digestion in people without the condition Enzyme activity, release characteristics and the complete formulation matter; capsule weight alone cannot establish … Read more
Key takeaways Lactase breaks down lactose, the sugar in milk; this mechanism is well established It does not remove milk proteins or make dairy safe for milk allergy Products may help some people, but the independently verified evidence does not establish a reliable benefit size for every supplement or user Tablets taken with food and … Read more
Key takeaways Capsaicin is the pungent compound in hot peppers. Sweet bell peppers, often called capsicum, are not an equivalent source There is insufficient independent human evidence to recommend oral capsaicin as a treatment for IBS, reflux, ulcers, or a damaged intestinal barrier Small experiments support changes in gut sensation. A reduction in burning does … Read more
Key takeaways Best fit: a specific oligosaccharide-rich meal that triggers gas Independent evidence: small, short studies; low confidence in the size and reliability of benefit IBS evidence: a selected GOS-sensitive subgroup, not proof of overall IBS treatment Activity units, food type and timing matter; an ingredient study does not validate every enzyme blend Diabetes medicines, … Read more
Key takeaways Betaine hydrochloride is an acidifying compound, not a digestive enzyme Small human studies investigated stomach pH or drug absorption; they do not establish lasting relief from common digestive symptoms The best-known experiments include pharmaceutical-industry funding; a later university study had a less direct but incompletely traceable funding chain Evidence for betaine anhydrous, also … Read more
Key takeaways Pepsin is an enzyme; it does not itself replace the acid-producing function of the stomach Pepsin-only products, pepsin with betaine HCl, and multi-enzyme blends require separate evidence The principal modern dyspepsia study located tested a combination and had manufacturer involvement A supplement response cannot diagnose a pepsin deficiency or low stomach acid Prescription … Read more
