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 the silkworm. The product also includes several inactive ingredients — microcrystalline cellulose, calcium phosphate, and others — that serve as fillers and binders to hold the tablet together.

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 isn't established in our data. We hold insufficient reliable evidence to rate it for chronic bronchitis, asthma, atherosclerosis, back pain, or osteoporosis — the conditions most commonly linked to it.

That doesn't mean it doesn't work; it means good clinical trials supporting these uses aren't on file yet.

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 is generally well tolerated short-term. The most common side effects are epigastric pain (upper stomach discomfort), gastrointestinal upset, and nausea — and these appear to occur at about the same rate as placebo in trials.

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

The safety data advises against use during pregnancy. While breastfeeding, there's no reliable safety information, so it's best avoided.

Talk with your pharmacist or doctor before using this if you're pregnant, breastfeeding, or planning either.

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 you take Serraflazyme, check with us if you're on any anticoagulant or antiplatelet drugs — blood thinners like warfarin, aspirin, clopidogrel, or similar medications. Taking this product alongside them may increase your bleeding risk.

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.

Serrapeptase may be worth considering if you've researched it for a specific condition and have no blood thinners or antiplatelet drugs in your regimen. If you take any anticoagulant or antiplatelet medication, double-check with us first — the interaction is a real concern.

Long-term safety hasn't been well studied, so keep that in mind.

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.
What is serrapeptase and what's it supposed to do?
Serrapeptase is an enzyme derived from silkworms. It's marketed for conditions like chronic bronchitis, asthma, back pain, and atherosclerosis, but the clinical evidence to support these uses isn't solid enough to rate in our data yet.
Can I take this if I'm pregnant or breastfeeding?
No, not during pregnancy — the safety data advises against it. While breastfeeding, there's no reliable safety information available, so it's best avoided. Talk with your doctor or pharmacist about personalized guidance.
What side effects might I notice?
Most common are upper stomach pain, gastrointestinal upset, and nausea — though these show up at about the same rate as placebo in studies. A rare serious side effect (bullous pemphigoid, a blistering skin condition) has been reported.
How long can I safely take this?
Short-term use is generally well tolerated. Long-term safety hasn't been well studied, so if you're thinking of taking it long-term, check in with your pharmacist first.
Does serrapeptase interact with other supplements or foods?
Our data covers interactions with medications only, not other supplements or foods. If you're taking other supplements, ask us to help you sort through any potential overlaps.
