HelloPharmacist Scorecard of Stomach Mender by BioAnue

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (260 mg) without saying how much of each component you get.

Stomach Mender contains 3 active ingredients: pepsin (a digestive enzyme), bile extract, and chaga extract, blended together in a proprietary formula. Pepsin is a protease — an enzyme that breaks down protein in the stomach.

Bile extract supports fat digestion and nutrient absorption. Chaga is a mushroom extract used traditionally in teas and foods.

The capsule itself is made of gelatin.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The product facts we hold don't include effectiveness ratings for pepsin or bile extract. For chaga extract, the evidence isn't established — we have insufficient reliable data to rate it for cardiovascular disease, diabetes, or COVID-19.

That doesn't mean it doesn't work; it means the science isn't settled yet.

The evidence, ingredient by ingredient Proteolytic Enzymes (proteases) Chaga

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pepsin is generally well tolerated for most adults, though it may cause digestive upset or allergic reactions in some people. Occupational exposure to airborne pepsin has rarely caused allergic rhinitis or asthma in workers.

Chaga is generally used in foods and teas, but human safety data are limited. There have been two reported cases of kidney failure and one case of acute kidney disease related to excessive chaga consumption due to its high oxalate content.

Safety hasn't been established in pregnancy or breastfeeding for either pepsin or chaga, so both should be avoided during pregnancy and breastfeeding unless your doctor advises otherwise.

Side effects, ingredient by ingredient Proteolytic Enzymes (proteases) Chaga

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Chaga.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your doctor or pharmacist before taking this if you use blood thinners or antiplatelet drugs like warfarin or clopidogrel, immunosuppressants, or antidiabetes medications — chaga may affect how they work. These are moderate-severity interactions that haven't been seen in humans yet, but they're worth confirming beforehand.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Stomach Mender may be worth considering if you're looking for digestive enzyme support, but the evidence for chaga's effectiveness isn't well established yet. If you take blood thinners, immunosuppressants, or diabetes medications, talk with your doctor or pharmacist before starting it.

Same goes if you're pregnant, breastfeeding, or have a history of kidney problems — get personalized advice from your own healthcare provider.

Stomach Mender by BioAnue: Common Questions

Does Stomach Mender by BioAnue interact with any medications?
Yes. Based on its ingredients, Stomach Mender has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Stomach Mender contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will Stomach Mender affect my blood thinner?
Chaga extract in this product may theoretically increase bleeding risk if you're on blood thinners or antiplatelet drugs — that's a moderate concern. This hasn't been reported in actual people, but it's important enough to discuss with your doctor or pharmacist before you start.
Can I take this while pregnant or breastfeeding?
No — safety data for both pepsin and chaga are too limited during pregnancy and breastfeeding. The facts advise against using either ingredient unless your doctor prescribes it. Talk with your own healthcare provider about whether it's right for you.
Does Stomach Mender actually work for digestion?
We don't have effectiveness ratings for pepsin or bile extract in our data. For chaga, the evidence isn't established — we can't say it works yet. That said, pepsin is a well-known digestive enzyme, but we can only tell you what the science we hold shows.
Are there any side effects I should know about?
Pepsin may cause digestive upset or allergic reactions in some people. Chaga is generally used in foods, but if you consume a lot of it, the high oxalate content has rarely caused kidney problems — so if you have kidney issues, mention this product to your doctor.
Is this safe if I take diabetes medication?
Chaga may theoretically increase the risk of low blood sugar if you're on antidiabetes drugs — a moderate concern that hasn't been seen in people yet. Check with your doctor or pharmacist before starting, especially if your blood sugar is already hard to manage.
What's bile extract for?
Bile extract supports fat digestion and nutrient absorption. We don't hold safety or effectiveness data for it, so we can't tell you much more — but your pharmacist can discuss it with you.
