HelloPharmacist Scorecard of Serraflazyme by Cardiovascular Research

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
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.

Serraflazyme contains one active ingredient: serrapeptase, an enzyme extracted from silkworm gut bacteria. The product also includes several inactive ingredients—microcrystalline cellulose, dicalcium phosphate, hydroxypropyl methylcellulose, silicon dioxide, magnesium stearate, and food glaze—which serve as binders, fillers, and coating.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Serrapeptase product and its label doesn't state a use — see Serrapeptase's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for serrapeptase is currently insufficient to rate it reliably for any of its common uses. Manufacturers market it for chronic bronchitis, asthma, atherosclerosis, back pain, and osteoporosis, but we don't yet have strong clinical data backing those claims.

That doesn't mean it doesn't work—it means more research is needed before we can say.

The evidence, ingredient by ingredient Serrapeptase

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.

Serrapeptase appears to be generally well tolerated in the short term, with most people experiencing no trouble. When side effects do occur, they're usually mild—some people report stomach pain, general gastrointestinal upset, or nausea, though these happen at about the same rate as placebo in trials.

A rare serious side effect (bullous pemphigoid, a blistering skin condition) has been reported. Long-term safety hasn't been well studied, so caution is warranted with extended use.

The safety data is insufficient during pregnancy, so it's best avoided then. There's no reliable safety information for breastfeeding either, so skip it if you're 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 — Serrapeptase.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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 Serraflazyme, double-check with your doctor or pharmacist if you're on any blood thinners (anticoagulants) or antiplatelet drugs like aspirin or clopidogrel—serrapeptase may increase bleeding risk with these medications.

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.

Serraflazyme may appeal to people looking for an enzyme supplement, though the clinical evidence doesn't yet support its common uses. If you take blood thinners or antiplatelet drugs, you'll need to clear this with your doctor or pharmacist first because of the theoretical bleeding risk.

Talk it over with your own healthcare provider before starting, especially if you're pregnant, breastfeeding, or taking any prescription medications.

Serraflazyme by Cardiovascular Research: Common Questions

Does Serraflazyme by Cardiovascular Research interact with any medications?
Yes. Based on its ingredients, Serraflazyme has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Serraflazyme 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.
Is serrapeptase safe to take long-term?
Not much is known about long-term safety. Serrapeptase appears well tolerated in the short term, but we don't have reliable data on what happens with extended use, so caution is advised if you're thinking of taking it regularly. Talk with your doctor about your individual situation.
What are the common side effects?
Most people tolerate it well. When side effects do happen, they're typically mild—stomach pain, general digestive upset, or nausea—and they occur about as often as placebo in trials. A rare serious side effect (a blistering skin condition) has been reported but is uncommon.
Can I take this while pregnant or breastfeeding?
No—there isn't enough safety data for pregnancy, so it's best avoided. If you're breastfeeding, there's no reliable safety information, so skip it. Talk with your doctor or pharmacist for personalized advice if you're in either situation.
Does serrapeptase actually work for the conditions it's marketed for?
The evidence is currently insufficient to rate it reliably. Serrapeptase is marketed for chronic bronchitis, asthma, atherosclerosis, back pain, and osteoporosis, but we don't yet have strong clinical data supporting those uses. That means more research is needed.
What is serrapeptase and where does it come from?
Serrapeptase is an enzyme isolated from the gut bacteria of silkworms. In laboratory studies, it shows fibrinolytic activity, meaning it can break down blood clots—which is why it's marketed for cardiovascular and inflammation-related conditions.
