What Customers Report With Daily Nattokinase and K2 Use
We built CardioFlow because we were tired of watching the category get away with diluted doses and vague labels. Customers who add it to their routine finally get both actives at the strength research actually calls for — no splitting softgels, no guessing, no second bottle for K2.

Didn't Know K2 Even Mattered
I'd never heard of pairing K2 with nattokinase until a friend mentioned it. Now I get both, full-strength, without figuring out separate dosing myself. Simple change, easy to stick with.
Stopped Buying Two Bottles
I was already taking a separate K2 supplement alongside my nattokinase — CardioFlow just combined what I was already doing into one softgel, at a real dose of both. One less bottle on my counter, same routine.
Exactly the dose I needed.
I've tried a couple of nattokinase brands over the years, but Aviora is the first one where I actually knew what I was getting. Two capsules, 10,000 FU, no blend, no serving-size confusion. Consistent use has made it an easy habit to keep.
More Than a Maintenance Dose – Full Concentration, Done Right.
Aviora delivers nattokinase at the full 10,800 FU dose used in research — not the diluted, split-across-softgel version most brands ship — paired with a full dose of Vitamin K2 (MK-7), researched for its own role in calcium metabolism and vascular flexibility. A delayed-release softgel shell protects both actives from stomach acid, while third-party testing verifies potency and purity in every batch.
- Full-strength 10,800 FU nattokinase
- Full-strength K2 (MK-7) — not a token amount
- No splitting softgels to hit the label claim
- Support for healthy circulation, from two different angles
- Verified potency, batch to batch
- One consistent daily routine
A Single Enzyme, Dosed at Full Strength.
Aviora delivers 10,800 FU of nattokinase per serving — the concentration used in research, not the diluted 2,000–4,000 FU maintenance dose most brands ship — paired with a full research-level dose of Vitamin K2 (MK-7), the nutrient most commonly recommended alongside it. Both actives sit in a delayed-release softgel built to survive stomach acid, so more of each dose reaches your bloodstream instead of breaking down early. Three softgels, once daily — no blends, no fillers, no serving-size math for either ingredient.
Backed By Research & Traditional Use
Nattokinase is an enzyme derived from natto, a fermented soybean food with centuries of traditional use in Japan, and it continues to be studied for its role in healthy circulation and fibrin balance. Aviora delivers it at 10,800 FU per serving — the concentration used in that research — with every batch independently tested for potency and purity. Designed for consistent daily support, not a quick fix.
Frequently Asked Questions
Find answers about Aviora’s formula, daily use, expected results, and quality standards.
What does the K2 in this formula do, and why is it paired with nattokinase?
What does the K2 in this formula do, and why is it paired with nattokinase?
Vitamin K2 (MK-7) is researched for helping activate proteins that direct calcium toward bone and away from soft tissue, supporting normal vascular flexibility — a different mechanism from nattokinase's role in fibrin balance. We paired them because that's how the research pairs them, not because one boosts the other's marketing story.
Why is the 10,800 FU nattokinase dose so important?
Why is the 10,800 FU nattokinase dose so important?
Because 2,000–4,000 FU — what most of the category ships — isn't the dose research actually uses. We built CardioFlow around the number that matters, not the number that's cheap to manufacture.
Can I take CardioFlow with my blood pressure or cholesterol medications?
Can I take CardioFlow with my blood pressure or cholesterol medications?
Nattokinase works with your body's natural fibrin balance rather than blocking enzymes. Vitamin K2, separately, can reduce how well warfarin works, since warfarin functions by blocking vitamin K. Talk to your doctor before adding it to your regimen, especially if you're on anticoagulants like warfarin or Eliquis.
How should I take it for best results?
How should I take it for best results?
Dosage: 3 softgels daily (10,800 FU Nattokinase + K2)
Timing: On empty stomach, 30 minutes before meals
Consistency: Same time every day — this is a routine, not a quick fix
Is it safe? What about side effects?
Is it safe? What about side effects?
Nattokinase has over 1,000 years of safe use in Japan and is well-tolerated. Vitamin K2 is also well-tolerated with no established upper intake limit. Do not take it if: scheduled for surgery within 2 weeks, have bleeding disorders, are pregnant/nursing, or take warfarin without doctor approval.
Can I take this instead of eating natto?
Can I take this instead of eating natto?
Yes — and honestly, that's part of the point. Natto's smell and texture keep most people from ever getting a consistent dose of either compound from food. We deliver both, full strength, verified, in a softgel you'll actually want to take every day.
