“My hands and feet are finally warm again”

For years my hands were ice cold no matter the weather. I’d wear gloves indoors. By week 2 of the full-dose nattokinase, the warmth started returning. By week 4, I was taking off my gloves indoors for the first time in years. My circulation is back.

30-Day Return Policy

If you don't notice a health boost, we'll refund you within 30 days of the product being delivered to you. No hassle or questions asked.

How does it work?

Nattokinase supports your body's natural fibrin-clearing activity, while Olive Leaf and Pine Bark Extract support healthy blood vessels and blood pressure already within normal range.*

What Does Nattokinase Help With?

Nattokinase is an enzyme made by fermenting soybeans with Bacillus subtilis natto, the same process behind natto, a traditional Japanese food. It supports your body's natural fibrinolytic activity, the built-in process that clears fibrin once its job is done, to help maintain healthy blood flow.* Our delayed-release capsule is designed to help protect the enzyme from stomach acid.*

When Will I See Results?

Everyone's different. Many customers say they start noticing warmer hands and feet and lighter-feeling legs within the first few weeks of daily use.* For best results, take it consistently for at least 60–90 days.* Individual results vary.

Who Can Use It?

Nattokinase is for adults looking to support healthy circulation.

Not recommended for children under 12, pregnant or nursing women. Consult your doctor if you take blood thinners or have bleeding disorders.

Results or Full Refund Guarantee?

We offer a 30-day money-back guarantee. If you're not happy with how you feel within 30 days, contact our support team for a full refund, no questions asked. You don't even need to return the product.

Why Most Nattokinase Supplements Fall Short

(And Why Ours Actually Does)

You’ve tried nattokinase. Your hands are still cold. Your legs still feel heavy by evening. Here’s why:

The dose problem.

Some published nattokinase research has used doses as high as 10,800 FU per day. Most brands on the market stop at 2,000 to 4,000 FU — because authentic Japanese-strain nattokinase is expensive. So they print a smaller number on the front and hope you won’t compare.*

The capsule problem.

Nattokinase is an enzyme — and enzymes are sensitive to stomach acid. A standard capsule exposes it to acid before it reaches your intestines, where it’s absorbed. Delayed-release capsules cost more, so many brands skip them.*

The fermentation problem.

Real nattokinase comes from fermentation with Bacillus subtilis natto — the same process behind natto, a traditional Japanese food eaten for centuries. Generic strains can produce inconsistent enzyme activity, and many brands don’t specify the strain on their label.*

This Is Where Purely Nutrient Changes Everything:

We deliver 10,800 FU per serving — more than five times what many brands offer.

We use a delayed-release capsule designed to protect nattokinase from stomach acid, so it reaches your intestines intact.*

We use authentic Japanese-strain nattokinase from Bacillus subtilis natto — a fermentation method rooted in traditional Japanese cuisine.

We pair it with Olive Leaf Extract (to support healthy blood pressure already within normal range) and Pine Bark Extract (to help protect blood vessels from oxidative stress).*

The result: Complete circulation support, at a potency most brands won’t match.*

Most nattokinase brands hope you don’t ask the hard questions. Purely Nutrient focuses on the dose, the delivery system, and the fermentation quality.

Modern Living Is Slowing Down Your Circulation

Here’s what’s happening inside your body:

Fibrin is a natural protein your body uses every day to patch tiny damage and support healing. Normally, your body clears it once its job is done.

But with age, your body’s natural clearing activity can slow down.* Add processed foods, chronic stress, and sitting all day — and circulation can start to feel sluggish.

71%

of adults over 50 report cold hands and feet, heavy legs, or afternoon energy crashes.

When your circulation slows down:

Your hands and feet stay cold — even in a warm room.*

Your legs feel heavy by dinner — sluggish circulation leaves them tired and achy.*

Your energy crashes in the afternoon — your brain and muscles aren’t getting the oxygen-rich blood flow they need.*

Your joints feel stiff in the morning — reduced circulation means less oxygen reaching tissues.*

You feel foggy and unfocused — your brain runs on healthy blood flow.*

It’s not just aging. It’s your circulation.

Nattokinase: Nature’s Most Powerful Solution For Healthy Circulation

For centuries, natto has been a staple of traditional Japanese diets. Now nattokinase — the active enzyme in natto — is available at a high potency, in a delivery system designed to survive digestion.

With 10,800 FU of authentic Japanese-strain nattokinase + Olive Leaf Extract + Pine Bark Extract, Purely Nutrient delivers what your circulation needs:

Supports Natural Fibrin Clearing

Nattokinase supports your body’s natural fibrinolytic activity — its built-in system for clearing fibrin once its job is done — helping maintain healthy blood flow.*

Built to Survive Digestion

The delayed-release capsule helps protect nattokinase from stomach acid, so more of the enzyme reaches your intestines, where it’s absorbed.*

Supports Healthy Blood Pressure

Nattokinase and Olive Leaf Extract help maintain healthy blood pressure levels already within normal range.*

Supports Warm, Healthy Circulation

Healthy blood flow helps keep your hands and feet warm and your legs feeling lighter.*

Supports Energy & Mental Clarity

Your brain uses about 20% of your body’s oxygen. Healthy blood flow supports oxygen delivery to your brain — helping you stay focused and energized through the afternoon.*

Supports Healthy Cardiovascular Function

Healthy circulation helps your whole cardiovascular system work efficiently.*

Helps Protect Blood Vessels

Pine Bark Extract helps protect blood vessels from oxidative stress, and Olive Leaf supports a healthy inflammatory response — rounding out complete circulation support.*

With Purely Nutrient’s 10,800 FU nattokinase in a delayed-release capsule, you’re supporting healthy circulation — rooted in centuries of traditional use and modern research.*

“My hands and feet are finally warm again”

For years my hands were ice cold no matter the weather. I’d wear gloves indoors. By week 2 of the full-dose nattokinase, the warmth started returning. By week 4, I was taking off my gloves indoors for the first time in years. My circulation is back.

“The heaviness in my legs is completely gone”

By dinner my legs felt like concrete heavy, swollen, exhausted. Two weeks into Purely Nutrient and the heaviness started lifting. By week 3, my legs felt light for the first time in a decade. I can climb stairs without stopping.

“My energy is back, no more 2 PM crash”

I’d hit a wall every afternoon like clockwork. After a month of the research-dose nattokinase, my afternoon energy is stable. I’m not crashing anymore. My brain is sharper and clearer than it’s been in years.

“I don’t need to stop and rest on stairs anymore”

Climbing stairs used to make my heart pound halfway up. I’d have to pause and catch my breath. Now I climb two flights without stopping. My heart feels strong. I’m not gasping for air. The difference in just 6 weeks is remarkable.

Frequently Asked Questions

Can I buy Purely Nutrient Nattokinase in stores?

Currently, Purely Nutrient Nattokinase is only available online through our official website. This allows us to maintain strict quality control, ensure the full research dose in every capsule, and offer better pricing by eliminating retail markups.

No fillers, no additives, no artificial ingredients. Just pure, research-dosed nattokinase with cardiovascular-supporting co-nutrients.

Why is the 10,800 FU dose important?

Some published nattokinase research has used 10,800 FU per day. Many brands on the market offer 2,000–4,000 FU. Purely Nutrient delivers 10,800 FU per 2-capsule serving, so you're getting the amount used in that research.*

Why do you use a delayed-release capsule?

Nattokinase is an enzyme, and enzymes are sensitive to stomach acid. Our delayed-release capsule is designed to help protect it through the stomach so more of it reaches your intestines, where it's absorbed.*

Is Purely Nutrient Nattokinase safe to take with my current medications?

Nattokinase is a natural supplement and is generally safe to consume. However, since nattokinase has natural blood-thinning properties, if you’re taking blood thinners (warfarin, aspirin, clopidogrel) or have bleeding disorders, we recommend consulting your doctor before adding it to your routine to ensure compatibility.

How should I store Purely Nutrient Nattokinase?

Store in a cool, dry place away from direct sunlight. Keep the bottle sealed tightly. Do not refrigerate. For best results, use within 24 months of purchase date.

Does it support healthy blood pressure?

Nattokinase and Olive Leaf Extract help support healthy blood pressure levels already within the normal range.* If you have high blood pressure or take blood pressure medication, talk with your doctor before use.

How long until I feel results?

Everyone's different. Many customers say they start noticing warmer hands and feet and lighter-feeling legs within the first few weeks of daily use.* For best results, take it consistently for at least 60–90 days.* Individual results vary.

How often should I take it?

Take two capsules every morning on an empty stomach with water. Consistent daily use works best.*

How many capsules are in each bottle?

Each bottle contains 60 capsules, providing a 1-month supply when taking two capsules per day.

Are there any age or health restrictions?

Nattokinase is beneficial for most adults, especially those seeking cardiovascular support. It is not recommended for children under 12, pregnant or nursing women. If you take blood thinners, have bleeding disorders, or have any health concerns, consult your doctor before use.
