HelloPharmacist Scorecard of Bromelain 500 mg by NaturesPlus
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.
What’s inside
Full disclosure
This product contains one active ingredient: natural pineapple bromelain complex at 500 mg per tablet. Bromelain is a protein-digesting enzyme extracted from pineapple fruit and stem.
The tablet also contains several inactive ingredients—di-calcium phosphate, microcrystalline cellulose, cellulose, stearic acid, magnesium stearate, and pharmaceutical glaze—which are fillers and binders that hold the tablet together.
Does it work?
Couldn't assess
The evidence on bromelain for most of its common uses—hay fever, burns, cancer support, nerve pain from chemotherapy, poor circulation in the legs, and blood sugar control—is not yet established in the data we hold. All six of these uses are rated as having insufficient reliable evidence to rate its effectiveness.
If you're thinking about taking it for one of these reasons, talk to your pharmacist or doctor about what the current research actually supports.
How safe is it?
Well-documented data
Bromelain taken by mouth is generally well tolerated short-term, though safety data on long-term use is limited. The most common side effects are diarrhea, gas, stomach upset, and headache.
A small number of people may have allergic reactions, especially if inhaled—symptoms can include difficulty swallowing, throat itching, eye irritation, and asthma in occupational settings. During pregnancy, there isn't enough safety data, so it's best avoided.
The same goes for breastfeeding—we don't know if it's safe, so it's recommended to avoid it while nursing.
Meds to double-check
Moderate interaction found
Check your medications if you take blood thinners or antiplatelet drugs like warfarin, aspirin, or clopidogrel—bromelain may increase bleeding risk. Also double-check if you're on tetracycline antibiotics.
Use the search tool on this page with your exact drug names before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Bromelain might be worth considering if you're looking for a digestive enzyme, but it's not proven for the conditions it's often marketed for. If you take blood thinners or antiplatelet drugs, or tetracycline antibiotics, check with your pharmacist first.
Pregnant or breastfeeding? Skip it until you've talked to your doctor.

Bromelain 500 mg by NaturesPlus Drug Interactions
HelloPharmacist Interaction Report
NaturesPlus Bromelain 500 mg contains one active ingredient—bromelain, an enzyme from pineapple—that does interact with certain medications.
The most serious concern is with blood thinners and antiplatelet drugs (such as warfarin, aspirin, and clopidogrel). Bromelain may thin the blood on its own and could increase your bleeding risk if combined with these medications; there's even a case report of minor bruising when bromelain was taken alongside naproxen, an anti-inflammatory pain reliever.
Read the full breakdown — every affected drug type, severity by severity
Bromelain also has a minor interaction with tetracycline antibiotics (like doxycycline). Laboratory studies suggest it might boost how much tetracycline your body absorbs, though one clinical trial in healthy adults found no change in blood levels when the two were taken together.
Altogether, these interactions span 141 individual medications. Use the medication checker on this page to search your exact prescriptions before you start.

Natural Pineapple Bromelain Complex
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.
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.
