Hale Heart Nattokinase
- ✓ Clinically studied to reduce arterial buildup by 36%
- ✓ Attacks the inflammation & plaque that is the #1 of cause of cardiovascular disease
- ✓ Support healthy blood pressure and cholesterol
- ✓ 10,000 FU enteric-coated nattokinase + CoQ10, bromelain, turmeric, ginger, olive leaf, white willow bark
Take 4 capsules once daily with a glass of water, preferably in the morning on an empty stomach or as directed by your healthcare practitioner.
Each bag contains 120 enteric-coated capsules — a 30-day supply at the clinical dose FU nattokinase per serving.
For best results: take consistently at the same time each day. The enteric coating is designed to survive stomach acid so the enzyme reaches the small intestine intact.
- Clinically-dosed at 10,000 FU — the efficacy threshold from Chen 2022, not the underdosed 2,000 FU you'll find in most supplements
- Breaks down arterial buildup — supports the body's natural clearance of plaque (Chen 2022, Ren 2017)
- 36.6% carotid plaque reduction — observed in the Ren 2017 trial at clinical dosing
- Supports healthy fibrin breakdown — the same mechanism Dr. Sumi observed in his 1980 Tokyo lab discovery
- Promotes healthy circulation — supports normal blood flow and vascular function
- Supports healthy blood pressure — already within the normal range
- Supports healthy blood viscosity — helps maintain optimal flow through arteries and capillaries
- True enteric coating — survives stomach acid so the enzyme reaches the small intestine intact
- Synergistic co-factors — CoQ10, bromelain, turmeric, ginger, olive leaf, and white willow bark

What Customers and Doctors Are Saying About Nattokinase
How Arterial Plaque Causes 17,000,000+ Deaths Per Year
Arterial Plaque Quietly Becomes the Leading Cause of Heart Attacks and Strokes, And Is the #1 Cause of Death Globally.
Inflammation damages the wall
Your artery walls have a smooth inner lining only one cell thick. Pressure, blood sugar, and inflammation leave tiny nicks in it over the years. Each nick triggers a patch job, and that patching is the first step toward buildup.
Hear From Hale Heart Customers
“About four months now. No fireworks but I do feel sharper, and the morning walks aren't kicking my butt the way they were.”
“I tried everything for my high blood pressure: hawthorn, garlic, beet root. Wasted two years and nothing worked. Started Hale Heart at 10,000 FU and within 10 weeks my BP went from 152/92 to 121/78. This is the real deal.”
“Carotid artery scan 2 years ago showed some early plaque. I started Hale Heart probably 8 months ago. Last scan a few weeks ago and saw no progression and the tech said it actually looked a touch better.”
“After my cardiologist raised concerns about my artery health, I asked for six months to focus on lifestyle first. I started Hale Heart, cut processed foods, and walked daily. At follow-up, my doctor was surprised by my progress and told me to keep going.”
“My hands used to be cold all the time, even in the summer with the AC. That's the first thing I noticed go away. My husband takes it too — he says his legs aren't as tired after he does the yard.”
“Had a small stroke back in '22. I asked my cardiologist before I started this and he was fine with it as long as I kept up with my blood thinner meds. Last carotid scan in February showed no change from before, which he said was a good thing at my age.”
“I had a whole shelf of bottles. CoQ10, turmeric, ginger, a nattokinase one. This replaced four of them. My counter looks better and I'm spending less. That alone was worth it. The way I feel is a bonus.”
“What got me was the Dr. Whitefield's recommendation. Bought a 3-month supply on the strength of that. My triglycerides came down 30 points at my last physical, which my PCP wasn't expecting.”
“My sister forwarded me the article. I rolled my eyes — she's always sending me stuff. But I read it. Then I sat on it for a week. Then I ordered it last summer. My bloodwork in January was the best it's been in years. Don't tell my sister she was right.”
“I'm 71. Been on a statin since I was 58. Showed the bottle to my internist before I started, she said it was fine, just to keep an eye on my INR which I do anyway. BP's down a little, mind feels clearer in the mornings — could be coincidence but I don't think so.”
Six Things 10,000 FU of Nattokinase Does Inside Your Body
A four-decade clinical record on the enzyme Hiroyuki Sumi isolated from natto in 1980, and what it does between when you swallow the capsule and when it reaches your arterial walls.
Your Heart Stays Protected Long-Term
Daily 10,000 FU nattokinase supports cardiovascular health at the structural level, working on what your annual checkup was never designed to measure, so the years ahead look like the ones behind you.
Existing Plaque Begins to Shrink
In a 26-week clinical study (Ren 2017), nattokinase supplementation was associated with measurable reductions in carotid arterial plaque thickness — the structural buildup that has been forming for decades on the inside of your artery walls.
Trapped Cholesterol Gets Released
Nattokinase supports the body's natural processes for clearing oxidized LDL cholesterol that has built up in arterial walls over time, helping reduce the buildup that causes stiffness and restricted blood flow.
Dangerous Clots Stop Forming
Nattokinase supports healthy fibrin breakdown — the sticky protein that holds clots together — helping maintain smooth blood flow and supporting the body's natural anti-clotting processes.
Your Blood Pressure Drops Naturally
By supporting nitric oxide production, nattokinase helps arterial walls relax and expand naturally, supporting healthy blood pressure already within normal range.
Your Resting Heart Rate Improves
When arteries are flexible and clear, the heart doesn't have to work as hard at rest. Improved circulation supports a more efficient resting heart rate over time — a metric longevity research consistently associates with healthier aging.

Everything you might be wondering
If you're on any prescription blood thinner, please talk to your doctor before starting Hale Heart. Nattokinase has its own effects on circulation, and combining it with prescription anticoagulants without medical supervision is not advisable. We also recommend discontinuing Hale Heart at least 2 weeks before any scheduled surgery.
FU stands for Fibrinolytic Units, the standard activity measurement for nattokinase. Most published clinical trials use doses between 8,000 and 12,000 FU per serving. Hale Heart is dosed at 10,000 FU. Many drugstore products contain only 2,000-4,000 FU, which is below the dose used in most positive clinical outcomes.
Most customers report subtle changes around weeks 3–4, with more pronounced effects in the 5–8 week window, which is also where the published trials measured their outcomes. We strongly recommend giving Hale Heart a full 60 days before deciding whether it's right for you, which is why we built the 90-day money-back guarantee.
Nattokinase has been consumed as part of natto in Japan for centuries with no documented long-term safety concerns. Published trials have run as long as 6 months without adverse outcomes in healthy adults. Most of our subscribers take Hale Heart daily as part of their long-term cardiovascular routine. As always, talk to your doctor if you have specific concerns or take prescription medications.
Frankly, because most of the rest of the shelf is under-dosed. The clinical literature uses around 10,000 FU. Putting 2,000 FU in a capsule lets a brand keep cost of goods low and margins high, but the customer is left with a product that doesn't match the science. We chose to formulate to the top of the studied range. It costs us more per bottle. We think it's the right call.
Our nattokinase is purified from the fermentation process, and the finished extract is tested for soy protein residues. That said, if you have a known soy allergy, please consult your physician before starting any nattokinase supplement, including Hale Heart. We're transparent about this — every batch's COA is published on our site.
Our capsules use a plant-based enteric coating (HPMCAS) that resists stomach acid and dissolves in the higher-pH environment of the small intestine. This is the same coating technology used in pharmaceutical-grade enteric capsules. Without enteric coating, ConsumerLab testing has shown that most of the active enzyme is destroyed before absorption.
