About This Supplement+
Nattokinase is an enzyme derived from natto, a fermented soybean dish that's been part of Japanese breakfast tables for over a thousand years. Genki Superfoods delivers it at 10,000 FU per serving — a clearly stated, high potency dose, paired with CoQ10, bromelain, turmeric, dandelion root, aged garlic, grape seed, and pine bark extract in one daily capsule.
Who Is This For?+
For anyone looking to support healthy circulation as part of their daily routine, especially if you're curious about traditional Japanese wellness ingredients but don't want to eat natto itself. Not intended for pregnant or nursing women, anyone on blood-thinning medication, or anyone under 18 — check with your doctor first if that's you.
How To Take It+
Three capsules a day, with a meal, same time every day — that's the whole ritual. One bottle is 60 capsules, about three weeks of your full 10,000 FU. Circulation support isn't a one-and-done thing; it rewards the people who actually show up daily. The only trick is not running out.

My doctor recommended a high 10,000 FU dose of Nattokinase for circulation, and Genki is one of the few brands that actually delivers it. After just a few weeks, my hands aren't constantly freezing and my legs feel so much lighter. Great product, easy on the stomach, and totally worth it!
A Thousand-Year-Old Habit You've Never Tried
The Japanese don't outlive the rest of us on luck — they do it on a thousand-year-old fermented food, and one enzyme inside it: nattokinase, studied for supporting healthy circulation and a healthy heart. You'd need five stinking bowls a day to matter, and nobody's doing that. So we put the enzyme in a capsule at the dose that counts — a full 10,000 FU, five times what most bottles even list. They bank on you never checking. We put the number on the front.
How It Works
A tradition you can trust
Most supplements ask for blind faith. This one has centuries of history and a clearly stated dose.

One serving delivers the full 10,000 FU dose in a single sitting, clearly stated on every label. Best taken with a meal, at the same time each day.
02
Trust the tradition
The same enzyme found in a food Japan has eaten for centuries, now standardized to a dose most bottles never reach and backed by decades of research.
03
More than one ingredient
Paired with aged garlic, CoQ10, turmeric, grape seed, bromelain, and pine bark, six ingredients working alongside nattokinase instead of leaving it to work alone.
04
Support every day
Make it part of your routine. Circulation support that builds with consistency, not a single dose taken once in a while.
05
Try it risk-free
Backed by a 30-day money-back guarantee. If it's not a fit for your routine, get every dollar back, no complicated process.

Questions, answered
An enzyme derived from natto, a traditional Japanese fermented soybean food that's been part of the diet for over a thousand years. It's the fermentation process itself that produces the enzyme, not something added afterward. FU (Fibrinolytic Units) is the standard measurement used to describe how active a nattokinase supplement actually is, not just how many milligrams are on the label.
Most nattokinase supplements land around 2,000 FU per serving, and plenty don't list a Fibrinolytic Unit count on the label at all. Genki is dosed at 10,000 FU per serving, five times the typical amount, and it's paired with six supporting ingredients instead of nattokinase working on its own.
One serving (three capsules) daily, preferably with a meal and a full glass of water. Morning or evening both work fine, what matters most is taking it around the same time each day so it becomes part of your routine instead of something you remember sporadically.
One bottle is 60 capsules — three a day, which is your full 10,000 FU serving — so about 20 days a bottle. Since it works best as a daily habit, most regulars put it on Subscribe & Save so a fresh one lands before they run dry.
Nattokinase at 10,000 FU is the core of the formula, paired with six supporting ingredients: CoQ10, bromelain, turmeric, aged garlic extract, grape seed extract, and pine bark extract, all included to support circulation alongside nattokinase rather than leaving it to work alone. The full ingredient panel and exact amounts are listed on the label.
Yes. The capsules are vegetarian, and the full formula and supply details are printed on the label.
Pregnant or nursing women, anyone on blood-thinning medication, or anyone with a bleeding disorder should consult their doctor before taking this. It's also worth checking with your doctor if you have an upcoming surgery, since nattokinase can interact with clotting-related medications. Not intended for anyone under 18.
