Experience the high-strength potency of Avex Nutrition’s Nattokinase 10,000 FU, derived from natto — the traditional Japanese fermented soybean food from which this powerful enzyme was first discovered. Valued for its role in supporting healthy circulation and cardiovascular wellness, nattokinase provides targeted daily support for normal blood flow and healthy blood vessel function.*
Each serving delivers an impressive 10,000 FU of nattokinase activity — substantially higher than the 2,000–4,000 FU commonly found in standard formulas. Our high-potency formula is carefully produced to deliver consistent enzyme activity, giving you a clear, measurable dose of active nattokinase in every serving.
Designed for daily cardiovascular support, Avex Nutrition Nattokinase 10,000 FU helps support healthy circulation, normal blood flow, and overall heart and vascular wellness.*
Elevate your daily routine with a serious, high-strength enzyme formula built around one simple goal: powerful cardiovascular and circulatory support, every single day.*
Every day, your cardiovascular system works nonstop — circulating blood, delivering oxygen and nutrients, and supporting every organ in your body. But age, inactivity, poor diet, stress, and modern lifestyles can all place additional strain on healthy circulation and cardiovascular function.
Nattokinase is a powerful natural enzyme originally discovered in natto, a traditional Japanese food made from fermented soybeans. It has been extensively studied for its role in supporting healthy circulation, normal blood flow, cardiovascular wellness, and the body's natural processes for maintaining healthy blood vessels.*
Unlike ordinary nattokinase supplements that provide just 2,000–4,000 FU per serving, Avex Nutrition delivers a high-strength 10,000 FU dose — with enzyme activity measured in Fibrinolytic Units (FU), so you know exactly how much active nattokinase you're getting.
No weak proprietary blends. No token doses. No unnecessary fillers. Just a high-potency 10,000 FU of nattokinase designed for serious daily cardiovascular and circulatory support.
One enzyme. One powerful 10,000 FU serving. Daily support for healthy circulation, normal blood flow, and cardiovascular wellness — working quietly in the background while you sleep, eat, work, and live your life.*

★★★★★
“For the first time in months, I didn’t leave the appointment terrified.”
When my cholesterol came back high, I couldn’t stop thinking about it. My mum had heart problems, so every time I felt tired or out of breath my mind went straight to the worst-case scenario. I started taking my cardiovascular health much more seriously and added Nattokinase to my daily routine. At my next check, my cholesterol reading had come down. I actually cried in the car afterwards. It felt like I’d finally stopped moving in the wrong direction.

“Seeing my readings improve was such a relief.”
My cholestrol had become something I dreaded checking. I’d sit there watching the machine inflate, already anxious about what number was going to appear. It made me feel much older than I am. After making some lifestyle changes and adding Avex Nattokinase to my routine, my readings started looking much better. That little moment of seeing a lower number meant more to me than I expected. I finally felt like I was doing something positive for my future.

★★★★★
“I didn’t realise how much the numbers were affecting me.”
Being told my cholesterol was too high really shook me. I’ve always been the sort of man who just gets on with things, but suddenly I was lying awake thinking about heart attacks, my family and whether I’d ignored my health for too long. I cleaned up my diet, started walking every day and began taking Nattokinase. When my next cholesterol test showed an improvement, the relief was enormous. For me, it wasn’t just a number on a piece of paper, it felt like getting some confidence in my future back.
1,000-year-old Japanese Tradition, Concentrated Into 2 Capsules
Deliberately formulated without vitamin K2, for people whose doctors said "watch the K"
For over 1,000 years, families across Japan have started their mornings the same way: a bowl of natto - sticky, fermented soybeans. In 1980, Dr. Hiroyuki Sumi discovered why this breakfast deserved attention. Hidden inside natto was an enzyme: nattokinase. It has since appeared in 1,000+ of published studies on circulatory health. Main one, tracking people for 16 years.
The problem? Most supplements use doses far below what modern research explores. We formulated at 10,000 FU per serving - and removed vitamin K2 for medication-conscious customers.
RESEARCH-BACKED WELLNESS SUPPORT
Designed to deliver real, lasting results — not just quick fixes. Here's how your body begins to shift once you start taking it daily.

They Felt the Shift. You Will Too.
“Exactly the kind of daily support I was looking for.”
I wasn’t looking for a quick fix, I wanted something I could take consistently to support my body over the long term. These fitted perfectly into my routine. After a few weeks I started noticing that I wasn’t feeling quite so tired and heavy by the afternoon and I generally had more enthusiasm to get things done. I feel reassured knowing I’m giving my body some extra support at the same time.
"A clean product that actually works."
My cholesterol had been playing on my mind for months. When my next test showed it had come down, I felt like a weight had been lifted.
“I wish I’d started looking after myself sooner.”
You reach a certain age and suddenly start thinking much more seriously about how you want to feel over the next ten or twenty years. That was really why I ordered these. I wanted something simple that could support me without having a cupboard full of different products. I’ve been pleasantly surprised by how good I feel.
“Glad I gave it a try”
I’ve been using these for a while now and they’ve become one of the supplements I actually remember to take. I’m feeling good and will definitely reorder.
You got questions, we got answers
Nattokinase works differently than prescription drugs — it works with your body's natural fibrin balance rather than blocking enzymes. However, because it may influence normal clotting function, consult your doctor before adding it to your regimen, especially if you're on anticoagulants like warfarin or Eliquis.
Most supplements contain only 2,000–4,000 FU — fine for general maintenance, but not enough for meaningful daily support. The 10,000 FU dose is the high-potency strength used in nattokinase research.
Most customers notice improvements within 3-6 weeks:
Weeks 1-2: Better sleep, more energy
Weeks 3-4: Blood pressure improves, circulation increases
Weeks 6-8: Brain fog lifts, sustained stamina returns
Months 3-6: Significant blood pressure changes, plaque reduction (doctor-validated)
Consistency is key - take it daily for best results.
Nattokinase has over 1,000 years of safe use in Japan and is well-tolerated. It's a natural enzyme derived from fermented soybeans with an excellent safety profile.
Do not take it if: scheduled for surgery within 2 weeks, have bleeding disorders, are pregnant/nursing, or take prescription blood thinners without doctor approval.
- Dosage: 2 capsules daily (10,000 FU)
- Timing: On empty stomach (30 min before meals) for best absorption
- Consistency: Same time each day
- Support it: Heart-healthy diet, regular movement, plenty of water
Nattokinase works with your body, not as a replacement for healthy habits.
