Japanese family sharing a traditional natto breakfast

A 1,000-Year-Old Japanese Secret, Now in 2 Capsules

Made without vitamin K2 on purpose. Because some people were told to watch their K.

Every morning for a thousand years, Japanese families have eaten the same thing: natto. Sticky, fermented soybeans that most Westerners have never heard of.

In 1980, researcher Dr. Hiroyuki Sumi figured out what made natto so special. Buried inside it was a powerful enzyme called nattokinase. Since then, over 1,000 published studies have explored its effects on blood flow, arterial health, and overall circulatory function.

Here is the catch. Most nattokinase supplements on the market use a fraction of the dose that researchers actually study. Vitarlo delivers 10,800 FU per serving, and we deliberately left out vitamin K2 so you get the cardiovascular support without the interference.

Frequently Asked Questions

Can I take this with my blood pressure or cholesterol medications?

Yes. Nattokinase is a naturally occurring enzyme and works well alongside blood pressure and cholesterol medications. Many of our customers take Vitarlo as part of their broader cardiovascular routine. Vitarlo is formulated without vitamin K2, so there are no known interactions with statins or antihypertensives. As with any supplement, let your physician know you are taking it.

Can I take nattokinase with blood thinners?

We do not recommend taking Vitarlo alongside prescription anticoagulants (such as Warfarin or Apixaban), daily aspirin, or antiplatelet drugs. Nattokinase is a potent natural enzyme that supports healthy blood flow, and combining it with these medications can increase the risk of excessive blood thinning.

If you experience easier bruising, frequent nosebleeds, or bleeding gums, stop taking the supplement and contact your doctor. These are not signs that it is working, they are warning signs.

If you still want to use Vitarlo while on any of these medications, speak with your doctor first. Do not start without their approval.

Why does the 10,800 FU dosage matter?

The majority of nattokinase supplements on the market provide between 2,000 and 4,000 FU per serving. That falls well below the threshold used in published clinical research. Our formula delivers the full 10,800 FU per serving to match the concentrations that produced measurable outcomes in peer-reviewed studies.

How long before I see results?

Most people start noticing changes within the first few weeks, with deeper benefits building over 3 to 6 months:

Weeks 1 to 2: Improved sleep quality, steadier energy throughout the day

Weeks 3 to 4: First noticeable improvements in how you feel day to day

Weeks 6 to 8: Sharper mental clarity, less fatigue during physical activity

Months 3 to 6: Sustained improvements that become your new normal

Daily consistency matters. Nattokinase works best when taken every day without gaps.

Is nattokinase safe for long-term use?

Nattokinase has a well-documented safety profile spanning over 1,000 years of traditional use in Japan and multiple modern clinical trials. It is well-tolerated in healthy adults with no significant reported side effects. If you have a pre-existing condition or are currently on medication, please consult your healthcare provider before starting any new supplement.

Important: Avoid Vitarlo if you are preparing for surgery in the next two weeks, have a diagnosed bleeding disorder, are pregnant or breastfeeding, or are currently on prescription medication unless your doctor has given approval.

Why did you leave out vitamin K2?

Many nattokinase supplements include vitamin K2 because it naturally occurs in natto. We deliberately excluded it. Vitamin K2 can interfere with blood-thinning medications like warfarin, which means a significant number of the people who would benefit most from nattokinase cannot safely take products that contain it. By leaving K2 out, Vitarlo is one less thing you need to second-guess with your doctor.

What is your money-back guarantee?

Your first order is protected by our 90-Day Money-Back Guarantee. Try Vitarlo for at least 30 days. If you are not happy with your results, contact us at support@vitarlo.com. We will ask you to complete a short questionnaire so we can understand what happened, and then process your refund. No bottles to ship back. Less than 1% of our customers ever ask for one.

What is the recommended way to take this?

Dosage: 2 capsules daily (10,800 FU)

Timing: On an empty stomach, approximately 30 minutes before a meal

Consistency: At the same time each day for optimal absorption

Lifestyle: Pair with a balanced diet, regular activity, and adequate hydration

Nattokinase is most effective as part of a consistent, health-conscious routine.

What are the other ingredients and why are they included?

Our formula is built around one active ingredient: Nattokinase at a full clinical dose of 10,800 FU (540 mg) per serving. The remaining ingredients are present in minimal amounts and each serves a clear purpose:

Microcrystalline Cellulose (10 mg): A plant-derived fiber that ensures you receive an even, consistent dose in every capsule.

Cellulose (10 mg): A natural plant fiber that supports smooth digestion and proper breakdown of the capsule.

Silica (10 mg): Prevents ingredients from clumping so every capsule delivers the exact same potency.

Magnesium Stearate (10 mg): A vegetable-derived compound that ensures the capsule dissolves cleanly and predictably in your system.

Vegetable Capsule (HPMC): A plant-based shell with no gelatin or animal products. Gentle on the stomach and suitable for vegetarians.

Every inactive ingredient is included at the lowest effective amount. Nothing unnecessary, nothing artificial.
