The Reason Why Your Arteries Keep Clogging Isn't What You've Been Told
It isn't only cholesterol. Fibrin, a sticky protein, builds up in your blood and on your artery walls, and every year your body clears less of it. Cholesterol and calcium stick to it, the arteries narrow, the blood thickens and your heart has to push harder. Statins lower a number, but they never break down the fibrin underneath. That's why so many people feel:
Cold hands and feet, even in summer
Legs that feel heavy and tired by evening
Numbers their doctor keeps watching
The fear of a clot or a stroke that runs in the family
THE JAPANESE ENZYME
From clean arteries to warmer hands and feet
20,000 FU of nattokinase from fermented Japanese natto in two capsules a day: here's what makes Clarova different.
Helps Clean Your Arteries
Better Circulation
Breaks Down Blood Clots
Supports Heart Health
How Clogged Arteries Creep Up On You
Stage 1
Cold feet at night
Your hands and feet go cold even under the covers. You blame the weather or the thermostat. It's your blood moving slower than it should.
Stage 2
Heavy legs by evening
By the end of the day your legs feel like lead and the stairs leave you winded. Thick blood is pushing through narrowing arteries.
Stage 3
The letter from the doctor
Then a scan or a checkup says the word you were dreading: buildup. Now every headache and every tight chest makes you think about a clot or a stroke.
20,000 FU, NOT 2,000
20,000 FU Of Nattokinase In Every Two-Capsule Serving
Most nattokinase bottles stop at a 2,000 FU maintenance dose. Ours carries 20,000 FU in every two-capsule serving, ten times that amount.
From natto, the fermented soybeans the Japanese have eaten for hundreds of years. Non-GMO and lab tested, 60 capsules in every bottle.
- 20,000 FU Per Serving
- From Fermented Japanese Natto
- Breaks Down Fibrin
- Non-GMO, Lab Tested
One Japanese Enzyme. At The Full 20,000 FU.
Nattokinase from fermented natto, at the dose that matters, in two easy capsules.
Nattokinase, 20,000 FU
The enzyme from natto, the fermented soybeans the Japanese have eaten for hundreds of years. It breaks down fibrin, the sticky protein that thickens your blood and builds up on your artery walls, so your blood flows freely again.
Fibrin is the protein your body uses to form clots. When too much of it builds up, your blood thickens and it lines your artery walls. Nattokinase breaks it down so your blood moves smoothly again.
Two easy capsules with water, no aftertaste and gentle on your stomach. Non-GMO and lab tested.
YOUR BLOOD GETS THICKER EVERY YEAR
Why Diet And Statins Alone Stop Working
You cut the fat, you take the statin, and the buildup is still there. That's because cholesterol is only part of it. Fibrin is the sticky base the buildup grows on, and your body clears less of it every year. Nattokinase breaks fibrin down, which is why it works where diet alone stops working.

Rated 4.8 / 5.0 | ‘Excellent’
At 68, my heart is my top priority. My brother had a stroke at 70. Clarova is two capsules every morning, and my circulation hasn't felt this good in years.
Leon T • Verified Customer
My doctor had been watching the buildup in my arteries for two years. I asked for three months to try something first. At my follow-up the scan had improved.
Martha K • Verified Customer
I was the guy with cold feet in July. Four weeks in, my feet are warm and my legs don't ache after a long day in the shop.
