Health Benefits

Cardiovascular Health

Nattokinase actively breaks down fibrin in the blood, supporting healthy circulation and reducing the risk of arterial calcification.

Bone Density

The extremely high Vitamin K2 (MK-7) content activates osteocalcin, which binds calcium to the bone matrix rather than the arteries.

Microbiome Diversity

Fermented with Bacillus subtilis var. natto, it provides a resilient probiotic that survives the gastric passage to improve gut flora.

Preparation Guide

1

Fresh or fermented beans are the only source of active Nattokinase; supplements are less bioavailable.

Best For: Maximizing nutrient absorption and digestibility

2

Alternative Usage

Best For: General health maintenance

Therapeutic Recipes

Longevity Microbiome Bowl

A scientifically layered bowl combining high-fiber black rice with the cardiovascular power of Natto.

Clinical Focus

Supports arterial health via K2 and provides a dense matrix of pre- and pro-biotics.

01

Stir the Natto vigorously 50 times to activate the 'strings' and enzymes.

02

Place warm black rice in a bowl and top with the whisked Natto.

03

Arrange avocado, egg, and nori shreddings over the top.

04

Drizzle with tamari and enjoy immediately while enzymes are active.

Frequently Asked Questions about Natto

What is the best time of day to eat Natto?

Many longevity experts recommend eating Natto in the evening, as Nattokinase activity lasts for 8-12 hours, providing circulatory support while you sleep when blood flow is slowest.

Can I eat Natto if I am on blood thinners?

Caution is advised. Because Natto is extremely high in Vitamin K2 and has natural blood-thinning enzymes, you must consult your physician if you are taking medications like Warfarin.

How do I get past the strong smell of Natto?

Adding strong flavors like mustard, ginger, or kimchi can help mask the fermented aroma while adding their own health benefits.
