HelloPharmacist Scorecard of Enzyme Forte by Foster Regal

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

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.
  • “Pancreatin” is listed as a grouped ingredient — the label gives one combined amount (175 mg) without saying how much of each component you get.

Enzyme Forte contains 6 active ingredients: amylase, papain, protease, lipase, cellulase, and pancreatin — all digestive enzymes meant to help break down food — plus bile extract, which supports fat digestion. The product also includes several inactive ingredients: calcium phosphate, vegetable stearic acid, vegetable cellulose, silica, and vanillin.

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: Digestive enzyme support with meals.
  • We looked for evidence on: Dyspepsia, Exercise-induced muscle soreness, Wound healing, Indigestion, Bloating and gas, Inflammation.
  • The closest evidence on file: Papain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness (Natural Medicines).
  • Also on file: Papain is rated "Insufficient Reliable Evidence To Rate" for Wound healing.
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.

The evidence we hold for papain's uses — cancer, dental cavities, skin damage from radiation, exercise-related muscle soreness, shingles, and intestinal parasites — is insufficient to rate how well it works. Lipase shows the same picture for inflammatory bowel disease, indigestion, and premature infant nutrition: the data just isn't established enough.

We don't have effectiveness ratings on file for amylase, protease, cellulase, pancreatin, or bile extract.

The evidence, ingredient by ingredient Papain Proteolytic Enzymes (proteases) Lipase

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Papain is generally tolerated as food, but supplements can irritate the digestive tract and trigger allergic reactions (itchy eyes, runny nose, sneezing, stomach cramps, sweating, diarrhea). High doses may be unsafe and can cause serious damage like esophageal perforation or severe inflammation.

Avoid concentrated papain and unripe papaya products during pregnancy; there isn't enough data to recommend supplemental papain while breastfeeding. Protease and lipase are generally well tolerated but may cause digestive upset or allergic reactions in sensitive people.

Safety hasn't been established in pregnancy for protease or lipase, so avoid unless your doctor advises otherwise. Breastfeeding while taking these enzymes isn't well studied — check with your healthcare provider first.

Side effects, ingredient by ingredient Papain Proteolytic Enzymes (proteases) Lipase

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 3 matched ingredients can interact with medications — Papain.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 2 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.

If you take warfarin (Coumadin), check with your pharmacist or doctor before adding this product — papain may strengthen its blood-thinning effect. No other medication interactions are documented for the ingredients we could check.

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.

If you take warfarin (Coumadin), talk to your pharmacist or doctor before starting this product — papain in it may thin your blood too much. For anyone else, these enzymes are usually well tolerated short-term, though they can upset sensitive digestion or trigger allergies.

If you're pregnant or breastfeeding, discuss it with your healthcare provider first.

Warfarin (Coumadin)

Theoretically, papain might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Yes. Based on its ingredients, Enzyme Forte has a known interaction with 2 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Enzyme Forte 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.
What are digestive enzymes, and what do they do?
Digestive enzymes like amylase, protease, and lipase break down carbohydrates, proteins, and fats in food so your body can absorb them. Pancreatin is a blend of these enzymes, and bile extract helps your body handle fats.
Can I take this while pregnant?
There isn't enough safety data to recommend these supplements in pregnancy. Papain specifically should be avoided. Talk with your doctor or pharmacist before taking this product while pregnant — they can weigh the risks and benefits for your situation.
Can I take this while breastfeeding?
Safety data on supplemental digestive enzymes while breastfeeding is limited. Check with your healthcare provider first before using this product.
What side effects might I notice?
Most people tolerate these enzymes well. Some may experience digestive upset or allergic reactions like itchy eyes, runny nose, or stomach cramps. High doses of papain are unsafe and can cause serious damage. If you notice any allergic symptoms, stop and call your pharmacist.
Does this product work for indigestion or digestive problems?
Lipase is used for indigestion (dyspepsia) and inflammatory bowel disease, but we don't have enough evidence to say how well it works. Talk with your pharmacist about whether this product is right for your particular digestive issue.
Is this product safe for me if I have a digestive condition?
Lipase is generally well tolerated, but if you have a serious digestive condition, use it only under medical guidance. Check with your doctor first.
