Nattokinase 5,000 FU
The fibrinolytic enzyme isolated from Japanese natto (fermented soybeans). It goes to work on the sticky fibrin proteins behind blood clots and arterial plaque — the foundation of the whole bundle.
Two clinically-inspired formulas, one daily ritual. Nattokinase 5,000 FU to support cleaner arteries, paired with our Blood Pressure Support blend. Made in-house in our GMP-certified UK facility and third-party tested every batch.

Just one capsule of 5,000 FU Nattokinase and one scoop of Blood Pressure Support a day works on three fronts to support a cleaner, healthier cardiovascular system.
Nattokinase is one of the few orally-active fibrinolytic enzymes — it goes to work on the sticky fibrin proteins behind dangerous blood clots.
Emerging research from the Journal of the American College of Cardiology shows daily Nattokinase use is associated with reduced carotid artery plaque thickness.
With fewer obstructions, blood flows more freely — supporting healthy pressure, oxygen delivery, energy, and recovery. Customers feel it within 30 days.
In 2025, our team tested 8 leading UK Nattokinase brands at SORA Laboratories. 6 of 8 failed the standard GM0068 enzyme assay — meaning the capsules contained nowhere near the FU printed on the label.
The average Japanese person lives to 84.4 years. The average Briton? 80.9 years. That's around three and a half extra years of life — and the gap isn't shrinking.
Even more striking: Britons die of cardiovascular disease at around 1.5× the rate of the Japanese. Same heart. Same biology. Very different outcomes.
So what does Japan eat that we don't? Natto — a traditional fermented-soybean breakfast staple consumed daily by tens of millions of Japanese for over 1,000 years. It's where Dr. Hiroyuki Sumi isolated Nattokinase in 1980 — the powerful fibrinolytic enzyme behind every capsule of NF.

Nattokinase to work on plaque and clots — paired with a Blood Pressure Support scoop built around four researched, vessel-relaxing nutrients.
The fibrinolytic enzyme isolated from Japanese natto (fermented soybeans). It goes to work on the sticky fibrin proteins behind blood clots and arterial plaque — the foundation of the whole bundle.
A great-tasting daily scoop built around four researched, vessel-relaxing nutrients — beetroot, magnesium, potassium and red clover (full breakdown below).
High-nitrate beetroot your body converts into nitric oxide, helping blood vessels relax and widen for easier flow.
Supports healthy vascular tone and a normal, steady heartbeat. Delivers 43% of your daily reference intake.
Balances sodium and supports the body’s natural regulation of healthy blood pressure.
An isoflavone-rich botanical traditionally used to support circulation and flexible, healthy arteries.
Blood Pressure Support: about 1 scoop daily, 30 servings per tub. Other ingredients: beetroot, natural flavouring, citric acid, sucralose. Made in the UK. %RI = Reference Intake of an average adult (8,400 kJ / 2,000 kcal).
Nattokinase is one of the most-studied natural compounds in cardiovascular medicine — with over 40 published human clinical trials. Here are six of the most compelling — three on Nattokinase, plus beetroot, magnesium and potassium.
In a 12-month trial of 1,062 men & women (average age 68), daily Nattokinase at 10,800 FU/day was shown to significantly reduce carotid artery plaque, alongside improvements in total cholesterol (95.4% of patients), LDL (84.3%), HDL (89.1%) and triglycerides (85.2%).
View study (DOI: 10.3389/fcvm.2022.964977) →A landmark observational study of 29,079 Japanese adults tracked over 16 years found that those who ate the most natto had a 25% lower risk of cardiovascular death and a 33% lower risk of dying from ischemic stroke.
View study (DOI: 10.3945/ajcn.116.137281) →After just 2 months of daily Nattokinase, three of the key proteins that drive clot formation — fibrinogen, factor VII, and factor VIII — dropped significantly across healthy adults, cardiovascular-risk patients, and dialysis patients alike.

Lower cholesterol. Cleaner arteries. Better energy. Sharper thinking. Here's everything daily 5,000 FU Nattokinase has been shown to support — both directly in clinical trials, and indirectly through the cascade of better blood flow.
Plaque, reduced
In a 12-month trial of 1,062 men & women (avg. age 68), daily Nattokinase was shown to reduce carotid artery plaque by up to 36% — alongside significant improvements in total cholesterol, LDL, HDL and triglycerides.

The clinically-studied dose. Nothing complicated.
Take one capsule of Nattokinase and one scoop of Blood Pressure Support with a glass of water in the morning, on an empty stomach 30 minutes before food.
Important: If you take blood thinners (Warfarin, Eliquis, aspirin), are pregnant, or are scheduled for surgery within 14 days — speak with your doctor before starting.
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.
It’s the simple daily routine Thomas followed — three moving parts that work together. Two come in the box, one lands in your inbox.
