HelloPharmacist Scorecard of Bromelain 500 mg by Metabolic Maintenance

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Bromelain, an enzyme from pineapple stem. It's a single-ingredient supplement at 500 mg per capsule, with cellulose as an inactive ingredient (capsule filler).

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 — see Bromelain's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: inflammation, swelling, and digestive support.
  • We looked for evidence on: Allergic rhinitis (hay fever), Exercise-induced muscle soreness, Knee pain, Osteoarthritis, Postoperative pain, Postoperative swelling — and 4 related terms.
  • The closest evidence on file: Bromelain is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Bromelain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness, Osteoarthritis, Knee pain, Rhinosinusitis, and more.

The evidence we hold doesn't establish that bromelain works for the conditions it's marketed for — hay fever, burns, cancer support, nerve pain from chemotherapy, chronic venous insufficiency (poor circulation in the veins), or diabetes. All of these have been rated insufficient reliable evidence, meaning we don't have solid proof one way or the other.

The evidence, ingredient by ingredient Bromelain

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bromelain is generally well tolerated when taken by mouth short-term, though long-term safety data is limited. The most common side effects are diarrhea, gas, stomach upset, and headache.

Some people may develop allergic reactions — including rashes, hives, or even asthma-like symptoms if bromelain is inhaled — especially if they're already sensitive to it. During pregnancy, there isn't enough safety data, so the recommendation is to avoid it.

Breastfeeding safety is unknown as well, so it's best to skip it while nursing. Talk with your doctor or pharmacist before using bromelain if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Bromelain

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 1 matched ingredient can interact with medications — Bromelain.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 141 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 blood thinners and antiplatelet drugs (like warfarin, clopidogrel, or aspirin) before starting — bromelain may increase bleeding risk. Also check tetracycline antibiotics, though the interaction is minor.

Use the medication search on this page to verify your exact prescriptions.

The bottom line

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

Bromelain may be worth considering if you're interested in trying a pineapple enzyme supplement, but know that the evidence for its marketed uses isn't solid yet. If you take blood thinners, antiplatelet drugs, or tetracycline antibiotics, check your specific medications with our tool before starting — the interaction risk is real.

Pregnant or breastfeeding? Skip it.

Talk to your pharmacist about whether this fits your situation.

Anticoagulant/Antiplatelet Drugs

Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.

Bromelain 500 mg by Metabolic Maintenance: Common Questions

Does Bromelain 500 mg by Metabolic Maintenance interact with any medications?
Yes. Based on its ingredients, Bromelain 500 mg has a known interaction with 141 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bromelain 500 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 is bromelain, and where does it come from?
Bromelain is an enzyme extracted from pineapple stem. It's been used traditionally in supplements for various purposes, though the evidence supporting many of those uses isn't strong yet.
Can I take this if I'm pregnant or breastfeeding?
No — there isn't enough safety data during pregnancy, so it's best avoided. Breastfeeding safety is unknown too, so you should skip it while nursing. Talk with your doctor before using bromelain if either applies to you.
What side effects might I notice?
The most common are diarrhea, gas, stomach upset, and headache when taken by mouth. Some people may have allergic reactions like rashes or hives. If you inhale it (occupational exposure), it can trigger asthma-like symptoms and throat irritation.
Is bromelain proven to work for hay fever, burns, or the other conditions listed?
The evidence we have doesn't establish that it works for any of those uses — hay fever, burns, cancer, nerve pain, circulation problems, or diabetes all fall short of reliable proof right now.
How long is it safe to take bromelain?
Short-term use appears well tolerated, but long-term safety data is limited. If you're thinking about taking it for weeks or months, talk with your pharmacist about whether that's a good idea for you.
