Frequently Asked Questions
Common questions we hear from Customers
How do I take Perennia?
One capsule daily with a glass of water, with a meal. That's the whole routine.
I'm on a blood thinner or daily aspirin. Can I take this?
Talk to your doctor first. Nattokinase works on fibrin — the same pathway as warfarin, Eliquis, Xarelto and aspirin — so the effects can stack. Same applies if you have a bleeding disorder or surgery coming up. This is the one real interaction with this ingredient and we'd rather you hear it from your doctor.
Can I take it alongside my statin?
Most people do. A statin lowers how much cholesterol your liver produces. Nattokinase works on fibrin, the mesh plaque builds on. Different mechanism, different target. Tell your doctor what you're taking, and never stop a prescription on your own. Aren't all nattokinase supplements the same? When will I see results? Why not just eat natto?
Aren't all nattokinase supplements the same?
No. In the research, reversal only appeared at high doses — below roughly 6,000 FU, studies found nothing. Almost every bottle on the shelf sits under 2,000 FU. Ours is 10,000 FU in a single capsule. (FDA SAFE)
NOTE: Please do not take anything above 10,800 FU of nattokinase (This is the regulated safe amount)
When will I see results
Circulation changes show up first, often in 3–5 weeks. Bloodwork moves more slowly — the study that measured plaque reduction ran a full year. Covered by our 100-day guarantee either way.
Why not just eat natto beans?
You'd need four or five packs a day to reach this dose, and the smell is the reason most people quit in week one. The enzyme is isolated, so you get the studied amount without the breakfast and the bitter taste.
Why It's Not a Willpower Problem
Plaque doesn't build on cholesterol alone. It builds on fibrin, a protein mesh inside the artery wall that catches cholesterol and holds it there while it hardens. Cut all the red meat you like: if the mesh stays, so does the plaque.
- Numbers that won't come down no matter what you cut
- Cold hands and feet, heavy legs on the stairs
- Doing everything right and still not feeling better
- That "am I next?" feeling every time a parent comes up
The Japanese Enzyme
Take apart the scaffold, not just the symptom
Perennia 10,000 FU nattokinase is fibrinolytic; it breaks down the fibrin mesh that arterial plaque builds itself on, at the dose the research actually used.
STAGE 1
The Silent Build
Nothing hurts. Nothing warns you. Fibrin lays down inside the artery wall and cholesterol starts catching in the mesh — through every year you felt completely fine.
STAGE 2
The Narrowing
Cold hands. Heavy legs. A pause halfway up the stairs you didn't used to need. The channel is smaller than it was, and your body starts economising.
STAGE 3
The Conversation
A scan, a number, a prescription — and a drug that halts the climb without reversing it. The plaque stops growing. It doesn't leave.
Arterial flexibility declines with age
The Hidden Driver Behind Hardening Arteries
Your body makes its own fibrin-clearing enzymes — and makes less of them every decade. As clearance falls behind buildup, the mesh thickens and the artery stiffens. Quietly, year after year.
What to expect as support builds over time
-
Week 1–2: Easy Start

- One capsule a day, with food
- No loading phase, no timing rules
-
Week 3–5: Circulation Shifts
The first thing most people notice has nothing to do with a lab report.
- Warmer hands and feet

"My brother needed a stent at 54 and that was my wake-up call. Eight months on this and my last panel was the best it's been since my forties. I don't dread the blood draw anymore."
"I'd tried three other nattokinase brands and felt nothing. Turns out they were all under 2,000 FU. This is the first one at the actual studied dose, and it's the first one that did anything."
"One capsule instead of the three my last brand wanted, and no aftertaste at all. My wife takes it now too. Simplest thing I've added to my routine in years."
