Exciting Chapter for Nattokinase

From White Blood Clots... to the Brain? New Research Opens an Exciting Chapter for Nattokinase.

When embalmers around the world began reporting unusual white fibrous clots during the pandemic, it sparked a conversation few people had ever heard before.

What were these clots?

Why were they appearing?

And more importantly, how does the body naturally maintain healthy blood flow?

For many people, that was the first time they encountered nattokinase—a natural enzyme produced during the fermentation of traditional Japanese natto. Since then, thousands of New Zealanders have added it to their daily routine to support healthy circulation and their body's natural fibrin balance.

Now, scientists are asking an entirely new question.

Could the same enzyme known for supporting healthy blood flow also help support the ageing brain?

A study that caught our attention

A newly published placebo-controlled human trial followed 120 adults over six months.

Half received 8,000 FU of nattokinase daily—equivalent to two Sacred Health Nattokinase capsules—while the other half received a placebo.

Researchers didn't just perform memory tests.

They also used sophisticated MRI brain imaging to look for changes inside the brain itself.

This is exciting because it marks one of the first human studies investigating whether nattokinase's vascular-supporting properties may also have implications for cognitive health.

Why this matters

Your brain may only make up around two percent of your body weight, but it consumes roughly twenty percent of your oxygen.

Every thought.

Every memory.

Every conversation.

Every decision.

All depend on an extraordinary network of tiny blood vessels delivering oxygen and nutrients exactly where they're needed.

Scientists have known for years that healthy circulation is critical for healthy ageing. What they haven't known is whether improving vascular health might also support normal brain function as we get older.

That's the question this new research begins to explore.

What the researchers found

The results were promising enough to get researchers talking.

Importantly, this wasn't a laboratory experiment or an animal study.

It was a randomised, placebo-controlled human clinical trial—the gold standard for early clinical research.

That doesn't mean we've found a miracle.

Far from it.

The study involved only 120 participants and lasted six months. That's enough to generate excitement, but nowhere near enough to claim nattokinase prevents dementia, reverses memory loss or treats cognitive impairment.

Responsible science doesn't work that way.

Instead, studies like this build the evidence one step at a time.

And this is an important step.

The bigger picture

Until now, most nattokinase research has focused on cardiovascular health.

Scientists have investigated its ability to support:

• Healthy fibrin balance

• Healthy circulation

• Normal blood pressure

• Healthy cholesterol metabolism

• Vascular health

Now we can add another fascinating area of investigation.

Healthy brain ageing.

It makes sense when you think about it.

Your brain relies on healthy blood vessels every second of every day. If vascular health matters everywhere else in the body, it's only natural to ask whether it matters just as much upstairs.

Researchers clearly think it's a question worth asking.

Science moves forward one study at a time

At Sacred Health, we're often asked why we follow research so closely.

The answer is simple.

Today's medical breakthroughs rarely arrive overnight.

They begin with observations.

Then questions.

Then carefully designed studies.

Then larger studies.

Eventually, enough evidence accumulates for scientists to reach strong conclusions.

This latest nattokinase study represents one of those important early steps.

It doesn't prove nattokinase prevents cognitive decline.

It doesn't claim to prevent dementia.

But it does suggest something genuinely exciting:

Supporting healthy circulation may have benefits that extend well beyond the cardiovascular system.

We'll continue following the science as more studies emerge.

Because that's exactly how evidence-based health should work.

Sacred Health Nattokinase

Each Sacred Health Nattokinase capsule provides 4,000 FU of high-strength nattokinase.

The new study used 8,000 FU daily, equivalent to two capsules.

While more research is needed, this latest study is another encouraging reminder that supporting healthy circulation isn't just about the heart.

It may also be an important investment in keeping both your body—and your brain—performing at their best for years to come.
