Nattokinase is backed by over 200 published studies, including randomized controlled trials and one of the largest cardiovascular epidemiological studies ever conducted. Here's what the research shows:
Arterial Plaque Reduction — A 2022 study of 1,062 participants (aged 63–85) showed a 36.6% reduction in carotid artery plaque after 12 months of nattokinase supplementation. A separate head-to-head trial found nattokinase reduced plaque 3× more effectively than the leading statin drug (36.6% vs. 11.5%).
Blood Pressure Support — Multiple randomized, double-blind, placebo-controlled trials demonstrate nattokinase acts as a natural ACE inhibitor, with an average systolic blood pressure reduction of 5.55 mmHg. A 2023 meta-analysis of 6 trials (546 participants) confirmed these results with statistical significance of p < 0.00001.
Cholesterol & Lipid Support — Clinical data shows a 15.9% decrease in total cholesterol, 18.1% decrease in LDL-C, and 15.8% increase in HDL-C, with enhanced results when Vitamin K2 is co-administered — which Senaria includes in every serving.
Cardiovascular Mortality — The Takayama Study tracked 29,079 Japanese adults for 16 years and found a 25% reduction in cardiovascular death and a 32% reduction in stroke death among the highest natto consumers. Non-natto soy showed no benefit — confirming it's the enzyme that matters, not soy in general.
If you care about healthy circulation, cardiovascular wellness, and staying active as you age — Nattokinase was made for your daily routine.

Sourced From Nature. Engineered for Your Circulation.
Your blood vessels work around the clock. The sluggishness, the heaviness in your legs, the pressure that builds through the day — your body is asking for support. Nattokinase 10,800 FU delivers it: nattokinase, CoQ10, bromelain, turmeric, aged garlic extract, and pine bark extract. No needles. No prescriptions. Just nature's most studied enzymes, in one capsule.
Nattokinase 10,800 FU
The enzyme that started the conversation. Derived from fermented soybeans, it's one of the most researched natural compounds for circulatory wellness. At 10,800 FU per serving, this isn't a token dose — it's the real thing.

CoQ10 for cellular energy. Bromelain from pineapple for enzymatic support. Turmeric for its active compounds. Aged garlic extract for vascular health. Pine bark extract for antioxidant strength. Six reasons this formula works harder than any single ingredient alone.
One Capsule. Pure Inside.
A single vegetarian capsule — no fillers you can't pronounce, no unnecessary extras. Just the formula, delivered in a clean, transparent capsule. What you see is exactly what you get.
Lab-Verified Quality
Every batch is tested in a certified laboratory for potency, purity, and safety. You're not trusting a label — you're trusting the data behind it. That's the Merosa Labs standard.
How Blood Clots Silently Kill 900,000 Americans Every Year
Most people never feel it happening. No warning. No pain. Just a clot forming quietly in an artery — until it isn't quiet anymore. Here's what's actually going on inside your blood vessels right now.
Stress, poor diet, and aging cause microscopic damage to your artery walls. Your body tries to repair it — but the repair process itself triggers a dangerous cycle of fibrin buildup that thickens the blood.
Fibrin is a protein your body uses to form clots. When it builds up faster than your body can break it down, blood starts to thicken and flow slows — quietly starving your tissues of oxygen.
Excess fibrin traps cholesterol and cellular debris, hardening into plaques along artery walls. These plaques narrow the passage, restrict circulation, and become dangerously unstable over time.
With narrowed arteries and thicker blood, your heart works harder to push circulation through. You may feel fatigue, cold hands and feet, or brain fog — your body is telling you something is wrong.
A plaque ruptures. A clot forms instantly and seals the blockage. Blood flow stops. Depending on where it happens — heart or brain — the result is a heart attack or stroke. This is the moment everything was building toward.
How to Use Nattokinase
Take your capsules daily with food for best absorption. Morning or evening — whatever fits your routine. Consistency over 4–8 weeks is where results happen.
"My legs don't feel heavy and swollen by the end of the day anymore."
I've had poor circulation in my legs for years — by evening they'd be puffy and aching, and I'd have to elevate them just to get comfortable. My doctor had mentioned nattokinase as something worth looking into, so I figured I'd try it. About three weeks in I noticed my legs weren't swelling as much after long days on my feet. Now, a couple months later, it's just not something I think about anymore. I honestly didn't expect it to make this much of a difference.*

"My cardiologist was actually impressed at my last check-up."
I've been managing high blood pressure and some concerns around arterial stiffness for about four years. A friend who's a nurse practitioner suggested I look into nattokinase as a complement to what I was already doing. I've been taking it every morning for about five months now, and my numbers at my last appointment were the best they've been in years. My cardiologist asked what I'd changed. I'm not saying it's a magic fix, but combined with diet and exercise, this feels like a real piece of the puzzle.*

"I've had cold hands my whole life — they're actually warm now."
This might sound small but it's a big deal to me. I've had cold hands and feet my entire life, even in summer. My mum was the same way — we just assumed it was genetic and nothing could be done. A coworker mentioned she'd started taking nattokinase for her circulation and her hands had improved, so I thought why not. After about six weeks I noticed my hands were staying warm throughout the day. I didn't even clock it at first until my husband mentioned my hands weren't ice cold when I grabbed his. Three months in and it's still holding.*

Frequently Asked Questions
If you're taking prescription medication, especially blood thinners, blood pressure medication, aspirin, or anything that affects clotting, speak with your doctor before using nattokinase. Nattokinase is a natural enzyme that supports healthy circulation, but it should not be used as a replacement for prescribed medication. Your doctor can help you decide if it fits safely into your routine.
FU stands for fibrinolytic units, which is how nattokinase enzyme activity is measured. Many basic nattokinase supplements use lower-strength servings, while this formula delivers 10,800 FU per serving for people who want a more serious daily circulation-support routine. It's made for consistency: one simple serving, clear potency, and no guesswork.
Nattokinase is not an instant-feel supplement. Most people take it daily for several weeks before judging how it fits into their wellness routine. For best results, use it consistently as directed on the label, ideally at the same time each day. Think of it as daily support for healthy circulation, not a quick fix you take only when something feels off.
Nattokinase is generally well tolerated by many adults, but it isn't right for everyone. Do not use it without medical approval if you take blood thinners, have a bleeding disorder, are pregnant or nursing, have surgery scheduled, or are under medical care for a heart or circulation condition. If you notice unusual bruising, bleeding, dizziness, or discomfort, stop use and speak with a healthcare professional.
Yes, if you want the nattokinase enzyme without eating traditional natto. Natto is a fermented soybean food with a strong smell, sticky texture, and taste that not everyone enjoys. These capsules give you a convenient, odorless way to add nattokinase to your daily routine, with a clearly measured 10,800 FU serving.
