Most brands never test after formulation. We test every single production batch through an independent ISO 17025 accredited laboratory before it ships.
Every batch goes to an independent laboratory — tested for what's in it, and for what shouldn't be.

This is why we recommend a 12-month autoship — research shows that's how long it takes for nattokinase to deliver its full effect.
Plaque buildup restricts blood flow. Fibrin, cholesterol and calcium have formed blockages inside artery walls over years.
Nattokinase is actively breaking down fibrin and activating your body's natural clot-dissolving system. Improvements in blood viscosity and flow begin.
Artery wall thickness is reducing. Cholesterol levels are improving. Blood vessels are strengthening and becoming more elastic.
After 12 months of consistent daily use, research showed artery wall thickness dropped from 1.33 mm to 1.04 mm and plaque reduced by up to 36%.
Based on a 12-month study with 1,062 participants at 10,800 FU/day. doi.org/10.3389/fcvm.2022.964977

Now non-hypertensive. I have been using the supplement for 33 days. My doctor has just confirmed I am now non-hypertensive.
It works. Down from 145/94 to 125/82 on average.
I can genuinely feel the benefits. At 59 years old I had growing concerns about my arterial health. I am only three weeks in and my breathing is better, I'm feeling more awake and I cannot recommend Nattokinase enough!
Incredibly impressed by the results. My blood pressure was on average 155/95 and my latest reading was 119/75. I found Natural Foundation and I have to say I'm incredibly impressed.
A customer for about 4 months. My blood pressure has come right down so I will keep taking it.
Recommend to all my patients. Been on Nattokinase for several months. I like it and recommend to all my patients and family. I am a physician in practice.
BP is definitely sorting itself out. Started taking the tablets about 3 weeks ago and my blood pressure is definitely sorting itself out — steady and a lot lower which is a big relief.
Outstanding. I've noticed a change in my circulation. It feels a lot different for the better.

About the Product
A capsule supplement for cardiovascular health containing 5,000 FU of Nattokinase alongside Motherwort and Oregano extracts — clinically studied and traditionally used ingredients for heart and artery support.
A fibrinolytic enzyme derived from natto, a traditional Japanese fermented soybean food used for centuries and widely researched for cardiovascular health.
Motherwort improves heart function, normalises blood pressure, and has cholesterol-reducing properties*. Oregano supports cardiovascular health, strengthens blood vessels, and increases elasticity of blood vessel walls*.
Many customers already take Vitamin K with Vitamin D, causing doubling-up. Also, Nattokinase supports blood flow while Vitamin K is a clotting agent — somewhat counterproductive. We recommend a separate D3+K2 alongside.
