7 Reasons Why People With a Family History of Heart Disease Are Switching to Nattokinase In 2026 - And What to Look for Before Choosing a Brand
Posted By Dr. Markus Schneider, MD, FACC

1. Nattokinase targets an arterial problem that your bloodwork can't show you
A normal check-up doesn't always tell the full story. Plaque can build up inside your arteries slowly, with no symptoms and no warning — and standard blood tests don't measure it directly.
That's the gap nattokinase is meant to help close. It works on arterial health in the background, whether or not it shows up on your next lab report.
2. Nattokinase supports your body's own fibrin-clearing system
Plaque builds up when a protein called fibrin collects in your arteries faster than your body can clear it. This clean-up process is called fibrinolytic activity, and it naturally slows down after age 50.
Nattokinase is an enzyme that has been clinically studied to support this process — helping your body clear fibrin the way it's supposed to.
Maybe you've already cleaned up your diet, added fish oil or CoQ10, or even tried a low-dose nattokinase and felt nothing. That doesn't mean those choices were pointless — and it doesn't necessarily mean nattokinase “doesn't work for you.” It may simply mean the dose you tried never matched the amount used in the research that actually measured a difference.
3. Clinical research showed measurable changes in arterial plaque at 10,800 FU a day
In a 12-month study published in Frontiers in Cardiovascular Medicine in 2022 with 1,062 adults, people who took 10,800 FU of nattokinase every day saw real changes. Their HDL ("good") cholesterol rose by nearly 16%, and their arterial plaque was reduced. The group taking 3,600 saw no measurable changes.
This was a large, real-world study, not a small placebo-controlled trial — worth knowing, and worth telling you directly. It's still the strongest dose-specific evidence we have, which is why Valera matches it exactly: 10,800 FU per serving.
THE DOSE PROBLEM
A big FU number on the label only matters if the product actually delivers what it claims.
Most nattokinase supplements still provide around 2,000–4,000 FU per serving. In the same 12-month research above, the lower-dose group taking 3,600 FU showed no measurable changes — so the FU amount clearly matters.
5 out of 8 nattokinase products in ConsumerLab's 2025 testing fell outside its acceptable range for their claimed enzyme activity. Two delivered far less activity than the label claimed.
That's why the smartest way to shop isn't “which bottle has the biggest number?” It's: What is the FU per full daily serving, is the label straightforward, and is the brand giving me a reason to trust the number?
Valera states the full 10,800 FU per daily serving plainly instead of hiding the number behind “per gram” math or an unclear serving calculation.
4. Nattokinase gives your body powerful support for breaking down fibrin
Nattokinase is unusually active against fibrin. In laboratory and preclinical research, its fibrinolytic activity has been measured at roughly four times that of plasmin — one of the body's own fibrin-breaking enzymes. That's a big part of why nattokinase has attracted so much attention for healthy circulation.
That strength naturally raises the next question: “Am I going to bleed?” Across the randomized clinical trials summarized in a 2024 meta-analysis, researchers did not report a common major-bleeding signal from nattokinase.
Important: If you take warfarin, Eliquis, Xarelto, Plavix, daily aspirin or another blood thinner/antiplatelet; have a bleeding or clotting disorder; or have surgery or a dental procedure coming up, talk with your doctor before using nattokinase. Valera is not a replacement for prescribed medication.
Soy allergy: Valera's nattokinase is produced from fermented soy and the finished product contains soy. If you have a severe soy allergy, ask your doctor or allergist before taking it. We'd rather put that here than not.

5. Nattokinase is one of the few supplements that gives you clear signs it's working
Most people can't tell if a supplement is doing anything. Nattokinase is different.
Valera customers notice warmer hands and feet within a few weeks. Others see it show up later, in a better blood pressure or cholesterol reading. Track your numbers before you start, so you have something real to compare.
6. Valera's nattokinase replaces a shelf of separate bottles
Valera combines 10,800 FU of nattokinase with six heart-supporting cofactors — CoQ10, bromelain, turmeric, ginger, olive leaf, and white willow bark — ingredients that support heart health from a few different angles, in one daily routine.
It's enteric-coated, so the enzyme has added protection from stomach acid before reaching the intestine. The full 10,800 FU daily serving is stated plainly on the label, so you know exactly what Valera is promising instead of decoding “per gram” math.
7. Valera has outstanding reviews and comes with a 90-day money-back guarantee
Valera is backed with a 90-day money-back guarantee — three times longer than the usual 30 days. That's because they'd rather you know it works than only give you 30 days, which may not be enough time for some people.
This isn't really a decision about buying a supplement. It's a decision about choosing long-term independence, staying active for loved ones, and not becoming another statistic. That's what you're rooting for when you try Valera risk-free today.
