HelloPharmacist Scorecard of pHysio Plus by ProEnzol

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proteolytic Enzyme Blend” is a proprietary blend — the label gives one combined amount (455 mg) without saying how much of each component you get.

pHysio Plus contains 3 active ingredients, all enzymes that break down proteins. Bromelain comes from pineapple, serratiopeptidase is a bacterial enzyme, and pHysioProtease is part of a proteolytic enzyme blend — enzymes designed to digest protein molecules.

The capsules also contain plant fiber and water as inactive ingredients.

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: manage inflammation and support immune modulation.
  • 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 for bromelain in this product isn't established for the conditions it's marketed toward — hay fever, burns, cancer support, nerve damage from chemotherapy, poor circulation in the legs, and diabetes. Our data rates all of these as insufficient reliable evidence, meaning the studies either don't exist, are too small, or don't show clear benefit.

We hold no effectiveness data for the other two ingredients.

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 short-term when taken by mouth, though we have limited long-term safety data. Common side effects include diarrhea, flatulence, stomach upset, and headache.

Some people may have allergic reactions to bromelain — if you've had sensitivity to pineapple or mold, mention that to your pharmacist. If bromelain is inhaled (which won't happen with capsules), it can cause asthma or throat irritation.

Bromelain is not recommended during pregnancy or breastfeeding — safety data is either absent or advises against it. We hold no pregnancy or breastfeeding safety data for serratiopeptidase or pHysioProtease.

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.

Before taking pHysio Plus, double-check blood thinners and anti-clotting medications (anticoagulants and antiplatelets) — bromelain may raise your bleeding risk. Also confirm tetracycline antibiotics with your pharmacist, though the concern is minor.

We couldn't assess two of the three active ingredients because we hold no interaction data for them.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take blood thinners or tetracycline antibiotics, check with your pharmacist before starting this product. The evidence for what this supplement claims to do isn't strong enough to rely on yet.

Bromelain is generally easy on the stomach short-term, but talk to us about whether it makes sense for your situation.

Bromelain2 drug types · 141 drugs

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.

pHysio Plus by ProEnzol: Common Questions

Does pHysio Plus by ProEnzol interact with any medications?
Yes. Based on its ingredients, pHysio Plus 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?
pHysio Plus contains 3 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.
Can I take this if I'm on warfarin or aspirin?
Bromelain in this product may increase bleeding risk with blood thinners and anti-clotting drugs. Talk to your pharmacist or doctor before starting — they'll know your specific medication and can advise whether it's safe for you.
Is this safe to take while pregnant or breastfeeding?
Bromelain isn't recommended during pregnancy or breastfeeding — safety data is either not available or advises against it. Talk with your doctor or pharmacist about alternatives if you're expecting or nursing.
What side effects might I notice?
The most common are diarrhea, gas, stomach upset, and headache. Some people may have allergic reactions to bromelain, especially if you're sensitive to pineapple or molds. Stop and call your pharmacist if you notice throat itching, trouble swallowing, or rash.
Does this actually work for hay fever or burns?
We don't have strong evidence yet that bromelain works for hay fever, burns, or the other conditions this product claims to help with. The studies either don't exist or aren't clear enough to recommend it for those uses.
What are these enzymes supposed to do?
Bromelain, serratiopeptidase, and the proteolytic enzyme blend are all designed to break down proteins in your body. The theory is they may help with inflammation or healing, but the evidence isn't solid for most claimed uses.
Can I take this long-term?
We have good short-term safety data for bromelain, but long-term safety information is limited. If you're thinking of taking this regularly, ask your pharmacist what we know and whether it's right for you.
