HelloPharmacist Scorecard of Acid Ease by Nature's Way

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 Jul 11, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 3 of its 6 active ingredients.
  • “Active Enzymes” is listed as a grouped ingredient — the label gives one combined amount (182 mg) without saying how much of each component you get.

Acid Ease contains 6 active ingredients. The product includes three digestive enzymes — Amylase, Lipase, and Cellulase — along with an Active Enzymes blend, all meant to help break down food.

It also contains Slippery Elm and Marshmallow Root Extract (both traditional soothing ingredients for the digestive tract) and Gamma-Oryzanol (a compound from rice bran). The capsules also hold inactive ingredients — Hypromellose, Cellulose, and Ascorbyl Palmitate — which are standard fillers, binders, and preservatives.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Digestion support for sensitive stomachs.
  • We looked for evidence on: Dyspepsia, Irritable bowel syndrome (IBS), Inflammatory bowel disease (IBD), Constipation, Diarrhea, Heartburn — and 2 related terms.
  • The closest evidence on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Inflammatory bowel disease (IBD) (Natural Medicines).
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.
  • Also on file: Marshmallow is rated "Insufficient Reliable Evidence To Rate" for Constipation, Diarrhea.

The evidence on whether these ingredients work for digestive support is sparse. Gamma-Oryzanol is possibly effective for high cholesterol (dyslipidemia), but that's not what this product is marketed for.

Lipase, Slippery Elm, and Marshmallow Root all have insufficient reliable evidence for digestive issues like indigestion (dyspepsia), diarrhea, or inflammatory bowel disease — the research just isn't there yet to say they work. We hold no effectiveness data for Amylase or Cellulase.

The evidence, ingredient by ingredient Slippery Elm Marshmallow Lipase Gamma-oryzanol

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lipase, Slippery Elm, Marshmallow Root, and Gamma-Oryzanol are all generally well tolerated for short-term use in adults, but long-term safety data are limited. Lipase may cause gastrointestinal symptoms in premature infants (rare) and should only be used in that population under medical supervision.

For pregnancy: Lipase and Slippery Elm have too little safety data to know if they're safe — talk to your doctor. Marshmallow Root and Gamma-Oryzanol have not enough reliable data and should be avoided in pregnancy.

For breastfeeding: Lipase and Slippery Elm lack sufficient safety data — check with your healthcare provider. Marshmallow Root and Gamma-Oryzanol have no reliable data and should be avoided while nursing.

Slippery elm pollen is a known allergen and may cause rash or hives.

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?
  • 2 of the 4 matched ingredients can interact with medications — Marshmallow, Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 2,041 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.

Double-check any oral medications you take — Slippery Elm and Marshmallow Root may slow their absorption (Moderate severity for Slippery Elm, Minor for Marshmallow). If you're on lithium, hold on before starting — Marshmallow Root could raise your lithium levels and need your dose adjusted.

Anyone on blood thinners (anticoagulants) or antiplatelet drugs should also verify with your pharmacist, as marshmallow has theoretical antiplatelet potential.

The bottom line

Scorecard at a glancePartially disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Acid Ease may work for you if you're looking for digestive enzyme support, but the evidence that these ingredients actually help isn't solid yet. If you take any oral medications or lithium in particular, check them against this product's interactions before you start.

Talk to your pharmacist about whether it fits your routine and medications.

Marshmallow Root Extract3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D

Slippery Elm1 drug type · 2,022 drugs

Oral Drugs

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.

Acid Ease by Nature's Way: Common Questions

Does Acid Ease by Nature's Way interact with any medications?
Yes. Based on its ingredients, Acid Ease has a known interaction with 2,040 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Acid Ease contains 6 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.
Does this product contain any fillers?
Yes. Along with the active digestive enzymes and botanicals, Acid Ease contains Hypromellose, Cellulose, and Ascorbyl Palmitate as inactive ingredients — these are standard binders, capsule material, and preservatives.
Is it safe to take while I'm pregnant or breastfeeding?
The safety data are thin. Lipase and Slippery Elm don't have enough information — talk to your doctor or midwife for personalized advice. Marshmallow Root and Gamma-Oryzanol have insufficient reliable data and are best avoided during pregnancy and nursing. Check with your healthcare provider before starting.
Can this product actually help with indigestion?
The evidence isn't established yet. None of the main ingredients — Lipase, Slippery Elm, or Marshmallow Root — have reliable proof they work for indigestion (dyspepsia) in human studies. We just don't have the data to say whether they help.
What is Gamma-Oryzanol, and what does it do in this product?
Gamma-Oryzanol is a compound from rice bran. Research suggests it may help with high cholesterol, but that's not what Acid Ease is marketed for. In this product, its exact digestive role isn't backed by strong evidence.
Could this interact with my medications?
Possibly. Slippery Elm and Marshmallow Root may slow how your body absorbs oral drugs. If you take lithium, Marshmallow Root could raise your levels. Use the medication checker on this page with your exact prescriptions, or ask your pharmacist before you start.
Are the enzymes in this product derived from animals?
That information isn't in the product data we hold. Check the label or ask the manufacturer directly for details on enzyme sourcing.
