Nattokinase is truly a remarkable supplement.
At 10,800 FU daily, it reversed arterial plaque in 66.5% of patients over 12 months, with no side effects.
The rest of the data is even more insane.
Researchers tracked 1,062 people with confirmed hyperlipidemia and carotid artery plaque.
These weren't just healthy volunteers.
Every person had an ultrasound at the start and another after 12 months of daily nattokinase.
The study used two dose groups: 3,600 FU and 10,800 FU per day. The low-dose group saw almost no change in their plaque or lipid markers.
Even though it was the same supplement for the same amount of time, the dose made the difference.
At 10,800 FU, carotid artery plaque shrank by up to 36%. The arterial wall thickness decreased by 21.7% on average.
These are physical, structural changes that doctors measured and confirmed on ultrasound.
77.7% of participants showed measurable improvement in arterial wall thickness.
66.5% showed measurable reduction in plaque size.
Improvement rates across all markers ranged from 66.5% to 95.4% for the majority of over 1,000 people, not some few lucky responders.
The participants lipid results moved in every right direction simultaneously.
- Total cholesterol: down
- LDL: down
- Triglycerides: down
- HDL: up
No adverse effects were recorded at any point across the full 12 months.
Lifestyle also amplified everything.
Participants walking more than 5,000 steps daily responded better than sedentary ones, and those with higher BMI saw larger relative improvements, likely because they started from a higher risk baseline where there was more room to move.
The study also tested co-administration.
Vitamin K2 and low-dose aspirin taken alongside nattokinase produced a synergistic effect, outperforming nattokinase alone across cardiovascular markers.
If you're building a stack, that's the combination the data points to.
The researchers found the effective range is 6,000 to 12,000 FU daily. Most supplements in Europe are only 2,000 FU. That's a huge gap.
The data shows 2,000 FU does almost nothing to plaque, while 10,800 FU actually shrinks it.
All in all, truly an incredible enzyme.
David Sinclair says he’s been reversing plaque in his arteries with nattokinase.
On Peter Diamandis’ podcast, Sinclair shared that he’s been taking it for years and mentioned a Chinese study with 1,086 people that showed up to 95% plaque reduction in one year at sufficient doses (at least 12 fibrinolytic units daily). He also checks his own carotid arteries with ultrasound and says there’s no buildup.
Nattokinase is an enzyme from fermented soybeans that breaks down fibrin. Some human studies show it can help reduce arterial plaque and improve blood flow, but results vary. Larger, high-quality trials are still limited, so it’s considered promising but not definitive.
Cardiovascular disease is still the #1 killer. If there are accessible tools that support artery health beyond statins and lifestyle, it’s worth paying attention.
Have you heard about nattokinase or tried anything similar for heart health?
