How AzureVitamins Serrapeptase
Works in Your Body
From capsule to systemic action — here's exactly what happens when you take 120,000 SPU serrapeptase every day.
Take 1 Capsule Daily
Take on an empty stomach with at least 8oz of water — 30 minutes before a meal or 2 hours after. This gives serrapeptase direct access to your digestive tract without competing with food proteins.
Absorbed Into Bloodstream
Serrapeptase passes through the intestinal wall and enters the bloodstream — where it circulates and begins working systemically. Taking on an empty stomach is critical for full absorption and enzyme activity.
Breaks Down Unwanted Proteins
At 120,000 SPU, serrapeptase supports the body's natural breakdown of unwanted proteins — helping the body clear dead tissue and supporting normal systemic enzyme activity at a meaningful level.
Systemic Support Achieved
With serrapeptase active systemically, the body's natural enzyme processes are supported throughout. Consistent daily use at 120,000 SPU gives the enzyme activity level needed to work as a meaningful part of your wellness routine.
The Enzyme That Sets
the Silkworm Free
A silk cocoon is one of the toughest protein structures in nature. For thousands of years, the silkworm has used a single enzyme to dissolve it from the inside. Scientists spent decades figuring out what it was — and what it could do in the human body.
The Cocoon Problem
A silk cocoon is not just a protective shell — it is one of the strongest natural protein structures on earth. The silk fibre has a tensile strength comparable to steel. The silkworm builds this structure around itself during metamorphosis, then faces a single challenge: getting out.
It has no teeth, no tools, and no hands. It has only one thing — a proteolytic enzyme produced by bacteria living in its intestine. That enzyme dissolves the silk protein wall with extraordinary precision, breaking only the non-living structure and leaving everything else completely intact.
The Late 1960s Discovery
In the late 1960s, Japanese researchers studying the silkworm's biology isolated the bacteria responsible for producing this enzyme from the silkworm's intestine. The bacteria — Serratia sp. E-15 — was producing a protease unlike anything previously studied.
The enzyme — now called serrapeptase or serratiopeptidase — was found to have a remarkable property: it could break down non-living protein structures with precision, while leaving healthy living tissue completely undamaged. The same mechanism that frees the moth from its cocoon.
From Silkworm to Supplement
Today, serrapeptase is produced through controlled microbial fermentation of Serratia E-15 — no silkworms are used in production. The bacteria are cultured, grown, and the enzyme extracted and purified to pharmaceutical grade.
Since the 1970s, serrapeptase has been used clinically in Europe and Japan. It gained popularity as a systemic enzyme supplement due to its ability to support the body's natural protein breakdown processes — the same selective precision observed in the silkworm, now in capsule form.
Modern serrapeptase is produced by controlled fermentation of Serratia E-15 bacteria — a clean, pharmaceutical-grade process entirely separate from silkworms.
The Silkworm's Enzyme. In a Capsule.
AzureVitamins Serrapeptase delivers 120,000 SPU per serving — the same enzyme isolated from Serratia E-15, produced by pharmaceutical-grade fermentation, concentrated into 1 clean capsule. No silkworms. No fillers. Just the enzyme, at the highest potency available — verified by an independent third-party laboratory.
6 Reasons Customers Choose Our Serrapeptase
Supports Natural Protein Breakdown
Serrapeptase supports the body's natural ability to break down unwanted, non-living proteins — working selectively at the enzymatic level to support normal systemic function.
120,000 SPU — Highest Potency Available
Most serrapeptase supplements deliver 20,000–40,000 SPU per capsule. We deliver 120,000 Serratiopeptidase Units per serving — the full daily research-referenced amount in a single once-daily capsule.
Precision Enzyme Activity
Serrapeptase selectively targets non-living protein structures while leaving healthy tissue intact — the same mechanism that allows the silkworm moth to dissolve its cocoon without damaging itself.
Natural Fermentation Source
Derived from Serratia E-15 — the bacterial strain originally isolated from silkworm intestine in the 1960s. Produced today by controlled pharmaceutical-grade fermentation. No silkworms. No animal by-products.
Optimised for Systemic Absorption
Serrapeptase is destroyed by stomach acid if not properly delivered. Our HPMC capsule shell protects the enzyme through the stomach and into the small intestine — where it enters the bloodstream intact. Take on an empty stomach for full systemic activity.
Clean, Minimal Formula
Serrapeptase 60mg (120,000 SPU), Microcrystalline Cellulose, Silicon Dioxide, HPMC Capsule Shell. No fillers, no hidden blends, no magnesium stearate. Third-party tested for identity, potency, and purity.
What Our Customers Are Saying
Real results from real people — verified purchases only.
"Finally a serrapeptase at the right dose"
Been taking this for 8 weeks now. I researched serrapeptase for months before buying — most brands are 20,000–40,000 SPU and the studies I read used significantly higher amounts. AzureVitamins at 120,000 SPU is the only product that matched what I was looking for. Clean formula, no fillers, third-party tested. Already on my second bottle.
"Already on AzureVitamins Nattokinase — this was a no-brainer"
I've been an AzureVitamins customer for their Nattokinase for months. When they launched Serrapeptase at 120,000 SPU with the same clean formula standard I ordered the same day. Same brand transparency, same minimal ingredients, same third-party testing. Exactly what I expected. Not going anywhere else.
"Take it on an empty stomach — makes all the difference"
Important: you have to take this on an empty stomach or you're wasting your money. I missed that in week one. Once I started doing it correctly — 30 minutes before breakfast — I've been consistent ever since. High potency was the big selling point for me. The 4-ingredient formula is exactly what I wanted. No junk.
"As a nutritionist — this is the only serrapeptase I'd recommend"
I read every supplement label before I recommend anything to clients. Most serrapeptase products have 8–12 ingredients. AzureVitamins has 4: Serrapeptase 60mg (120,000 SPU), Microcrystalline Cellulose, Silicon Dioxide, HPMC Capsule Shell. No magnesium stearate. Third-party tested. The 120,000 SPU potency is the real deal — my clients are getting consistent results.
"Stocked up on the Buy 3 deal — best value for a premium formula"
Already taking AzureVitamins Nattokinase so this was a natural addition. Same brand, same standard, same third-party testing. The 120,000 SPU was a big factor — I wasn't going to bother with anything lower after doing my research. On my third bottle now. The Buy 3 Get 2 deal made it a no-brainer to stock up.
"Cleanest serrapeptase formula I've found"
As a nutritionist I read every ingredient label carefully. Most serrapeptase supplements have 10+ ingredients padding out the formula. AzureVitamins has just 4. Plus the 120,000 SPU is the real deal — no other brand at this potency has this few ingredients. My clients are getting consistent results.
Most Serrapeptase Supplements
Aren't Strong Enough
At 20,000–40,000 SPU, standard brands fall below the threshold needed to support meaningful systemic enzyme activity. AzureVitamins delivers 120,000 SPU per serving — potency that actually moves the needle.
The bottom line: AzureVitamins delivers 3× the enzymatic activity of the highest-dosed standard competitor — in a cleaner formula, at better value, backed by a 365-day guarantee.
