HelloPharmacist Scorecard of Bromelain 500 mg by Source Naturals

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 16, 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, a protein-digesting enzyme derived from pineapple stem. It comes in a 500 mg tablet form.

The tablet also contains several inactive ingredients — sorbitol, stearic acid, modified cellulose gum, colloidal silicon dioxide, and magnesium stearate — which are there to hold the tablet together and help it dissolve properly.

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: protein breakdown and physical stress support.
  • We looked for evidence on: Postoperative pain, Postoperative swelling, Exercise-induced muscle soreness, Wound healing, Inflammation, Swelling — and 1 related terms.
  • The closest evidence on file: Bromelain is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle soreness (Natural Medicines).
  • Also on file: Bromelain is rated "Insufficient Reliable Evidence To Rate" for Wound healing, Postoperative swelling, Postoperative pain.

The evidence for bromelain isn't firmly established yet. Our data shows insufficient reliable evidence to rate it for hay fever, burns, cancer, nerve damage from chemotherapy, chronic venous insufficiency (poor circulation in the legs), or diabetes.

That doesn't mean it doesn't work — it means we don't have strong clinical proof one way or the other. If you're considering it for one of these conditions, talk it over with your doctor or pharmacist to weigh what limited evidence exists against your own situation.

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 thin. The most common side effects are digestive — diarrhea, gas, stomach upset, and headache.

Less commonly, it may cause nausea, vomiting, or belly pain. Allergic reactions are possible, especially if you're sensitive to pineapple or bromelain itself.

If you inhale bromelain (occupational exposure), it can trigger asthma or throat irritation. The safety data during pregnancy advises against use, and there isn't enough information about breastfeeding — talk with your doctor or pharmacist about either if you're pregnant or nursing.

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.

Check before taking this if you use blood thinners or antiplatelet drugs (Moderate severity) — bromelain may boost bleeding risk. Also double-check if you're on a tetracycline antibiotic (Minor severity), as bromelain might change how much your body absorbs.

Your pharmacist can confirm your exact medications are clear.

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.

This supplement is a single-ingredient enzyme that may help with inflammation or digestion, though the evidence for specific conditions isn't strong. It's worth checking with your own doctor or pharmacist if you take any blood thinners, antiplatelet drugs, or tetracycline antibiotics before you add it — the search tool on this page will help you confirm your medications are safe to combine with it.

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 Source Naturals: Common Questions

Does Bromelain 500 mg by Source Naturals 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 a protein-digesting enzyme that comes from the stem of the pineapple plant. It's been used in supplements for potential anti-inflammatory effects, though research on its effectiveness for specific conditions is still limited.
What are the most common side effects?
Most people tolerate it well when taken by mouth. The most common side effects are digestive — gas, diarrhea, stomach upset, and sometimes headache. Less often, people report nausea, vomiting, or belly pain.
Can I take this if I'm pregnant or breastfeeding?
The safety data advises against bromelain during pregnancy. If you're breastfeeding, there isn't enough information to know whether it's safe — talk with your doctor or pharmacist for personalized advice on either.
Will this affect my blood thinner or aspirin?
Possibly. Bromelain may have mild blood-thinning effects, so combining it with medications that reduce clotting or prevent bleeding could raise your bleeding risk. Check your exact medications with your doctor or pharmacist before you start.
Is this proven to work for any particular condition?
The evidence for bromelain isn't firmly established yet for the common uses listed on supplements — hay fever, burns, cancer, nerve damage, circulation problems, or diabetes. Your doctor can help you weigh what research exists against your own needs.
