Experience the unparalleled potency of Rovina Nattokinase Capsules — the enzyme naturally produced when soybeans are fermented into natto, a traditional Japanese breakfast food eaten daily for over 1,000 years in regions that report some of the lowest cardiovascular mortality rates in the developed world.

Regarded as nature's most powerful fibrinolytic enzyme, nattokinase directly supports your body's own fibrin-clearing pathway* — the cleanup system that quietly slows down after age 50 and gets blamed on everything except the real cause. Our 10,800 FU clinical-dose capsules are meticulously crafted to be non-GMO, gluten-free, and free of unnecessary fillers, formulated in a delayed-release capsule with clinically-recognized supporting nutrients — CoQ10 Ubiquinol, turmeric, olive leaf, bromelain, and pine bark — for real absorption and complete cardiovascular support.

Backed by over 200 published studies on nattokinase and trusted by 100,000+ customers, Rovina delivers the exact enzyme dose used in the leading cardiovascular research — not the underdosed 2,000–4,000 FU maintenance formulas that fill most shelves.

Elevate your wellness journey with the elite protection of nature's most powerful cardiovascular enzyme.

Every day, your body performs two opposite jobs inside your arteries. It builds tiny repairs using a sticky protein called fibrin — the "mortar" that patches microscopic wear-and-tear. And it clears that fibrin back out using an enzyme called plasmin, so blood keeps flowing freely.

The building side works exactly as well at 65 as it did at 25. Only the clearing side slows down. After age 50, a compound called PAI-1 rises and quietly puts the brakes on your body's natural cleanup crew. The deposits keep arriving. The cleanup falls behind. And a standard cholesterol panel never catches it — because a blood test is an inventory, not a measure of how your blood actually moves.

That's where nattokinase comes in. It's the enzyme isolated from natto that directly supports your body's own fibrin-clearing pathway.* Research on high-dose nattokinase has examined its role in supporting healthy carotid artery function, healthy blood pressure levels already within normal range, and healthy circulation.*

But dose is everything. Most nattokinase on the market sits at 2,000–4,000 FU — the "maintenance" range. The published research showing meaningful cardiovascular support was run at 10,800 FU per day. Anything less is a lower dose than the research was actually built on.

Rovina delivers the full 10,800 FU clinical dose in a delayed-release capsule built to survive stomach acid — so more of the enzyme reaches your bloodstream instead of breaking down early. No proprietary blends. No serving-size math. No underdosed sprinkles.

One enzyme. One clinical dose. Daily support for the system nobody ever told you slowed down.

Yes, but consistency is everything.

Nattokinase is one of the most studied fibrinolytic enzymes in the world, with 200+ published studies examining its effects on healthy circulation, healthy fibrin balance, cardiovascular wellness, and healthy blood pressure support.

Clearing fibrin is a slow arc — most people feel nothing at all for the first 2–3 weeks. Early signs (warmer hands and feet, less swelling after long flights or drives, a calmer chest on the stairs) tend to show up between weeks 3 and 6. Measurable changes in the numbers people track at home typically appear between weeks 6 and 12.

Nattokinase — 10,800 FU

From traditional Japanese-strain fermented soybeans (Bacillus subtilis natto)

Nattokinase is the fibrinolytic enzyme first isolated in 1980 by Japanese researcher Dr. Hiroyuki Sumi, who found that the enzyme in natto could dissolve an artificial fibrin clot in a petri dish. It has since been evaluated in over 200 published studies for its role in supporting healthy circulation, healthy fibrin balance, and cardiovascular wellness.*

When taken consistently at the 10,800 FU dose — the exact potency used in the leading cardiovascular research — nattokinase may support multiple aspects of vascular wellness over time.*

FU stands for Fibrinolytic Units — the standard measurement of the enzyme's actual activity, not just its milligram weight. Higher FU means more real enzyme activity per capsule. Most competing products publish milligrams on the front and hide the FU rating (or omit it entirely). We publish both.

Supporting Actives

We paired the full clinical enzyme dose with five clinically-recognized ingredients that support the same system from complementary angles:

• CoQ10 Ubiquinol — 200 mg. The coenzyme every cell uses to produce energy — and one your heart, being the most metabolically active muscle you have, uses more of than almost any other tissue. Levels naturally decline with age. We use Ubiquinol rather than standard ubiquinone — the pre-reduced form your body absorbs and uses more readily.*
• Turmeric Extract — 500 mg. Standardized to curcuminoids, turmeric has been used for thousands of years in traditional wellness practice and is studied today for its role in supporting a healthy inflammatory response.*
• Olive Leaf Extract — 500 mg. A staple of traditional Mediterranean wellness, olive leaf contains oleuropein — a polyphenol studied for its role in supporting healthy blood pressure already within normal range.*
• Bromelain — 500 GDU. A naturally occurring enzyme from pineapple stem, most often paired with nattokinase because it supports the body's healthy response to protein turnover and healthy circulation.* GDU (Gelatin Digesting Units) is the actual activity measurement — the equivalent of "FU" for bromelain.
• Pine Bark Extract — 5 mg. One of nature's most concentrated sources of antioxidant OPCs, studied for their role in supporting healthy endothelial (blood vessel lining) function.*

Delayed-Release Capsule

Absorption support

Nattokinase is a protein, and proteins are vulnerable to stomach acid. A standard capsule can lose meaningful enzyme activity before it ever reaches the bloodstream. Our delayed-release capsule is designed to protect the dose through the stomach so more of what's on the label is what your body actually absorbs.

What's Not Included

• ✓ No artificial colors
• ✓ No flavors or preservatives
• ✓ Non-GMO
• ✓ Gluten-free
• ✓ No fillers or unnecessary additives
• ✓ No proprietary blends — every dose printed on the label

Step-by-Step Instructions

1. Take 2 capsules daily on an empty stomach — 30 minutes before a meal or 2 hours after eating. Food triggers digestive enzymes that can degrade nattokinase and bromelain before they're absorbed.
2. Timing: Morning or evening both work. Morning coincides with the daily window when cardiovascular events statistically peak; evening supports overnight circulation while you're lying still.
3. Be consistent — same time every day. This is a routine, not a quick fix.
4. Give it at least 8 weeks before judging results. Clearing fibrin is slow. The clinical arc is 8–12 weeks.
5. If you're on prescription medication — especially blood thinners like warfarin, Eliquis, or aspirin regimens — talk to your doctor first.

Published research on nattokinase shows that meaningful cardiovascular support builds over 8–12 weeks of consistent daily use. Early sensory changes (warmer extremities, less swelling, more comfortable stair climbing) tend to appear between weeks 3 and 6. Changes in the numbers people track at home typically show up between weeks 6 and 12.*

We recommend consistent daily use for at least 8 weeks to allow your body's fibrinolytic system time to catch up on the backlog.* Because this supplement supports wellness at the vascular level, ongoing daily use is recommended for continued support.*
