Most people take 8–12 weeks to notice a meaningful difference — some of the research behind nattokinase measures results over a full 12 months of consistent use. This isn't a short-term supplement. For the best results, we recommend a minimum 3-month commitment.
Yes, potentially — nattokinase can interact with blood-thinning medications (including aspirin, warfarin, and other anticoagulants), and may not be suitable if you're on blood pressure medication, scheduled for surgery, or pregnant/nursing.
Some people also notice an adjustment period in the first few days. Talk to your doctor before starting, especially if any of the above applies to you.
Take 2 capsules daily, ideally on an empty stomach for optimal absorption. Consistency matters more than exact timing — same time each day works well for most people.

Most Nattokinase Brands Are Cutting Corners. We're Not.
Most nattokinase research uses doses up to 10,800 FU. Most bottles top out at 2,000 — and independent testing has found some brands don't even deliver what they claim.
Meguri is 10,000 FU per serving, verified by third-party lab testing. The number on the label is the number in the capsule.

★★★★★The warmth finally returned to my hands!
My hands felt warm again for the first time in years, and I could actually taste my food properly again. Honestly, I'd almost given up — I'd tried a couple of other nattokinase brands before this one, all sitting around 2,000 FU, and felt nothing. I didn't realize the dose made that much of a difference until I actually took one that was formulated at the level the research uses. Wish I'd found this one first
Warm Hands True Taste -
★★★★★So many benefits I didn't expect
"I've been using this product for over 4 months. My blood pressure has lowered considerably and I feel good. It has also improved my eyesight. That surprised me, but when I thought about the artery declogging, it made sense. I highly recommend this brand and their product."
Lower BP More Energy -
★★★★★The only thing that helped me with long covid
It's one of the few things that's actually helped me with my long-covid. More energy, less pain, and I noticed it within a couple of weeks. I'm still in the trenches overall, so I won't pretend it's a full cure. But it's a real boost, and I'll take that. I've recommended it to a few others and they all say it's helped them as well. Everyone's different, which is why the 30 day gurantee is so reassuring.
More energy Less Pain
Proven Benefits. Backed by Science.
Your body deserves more than empty claims. Meguri® supports key areas of daily wellness using ingredients studied in clinical research.
Circulation
Support for healthy blood flow, daily
Nattokinase is studied for supporting the body's natural fibrin-breakdown process — the system behind healthy blood flow. Many notice warmer hands and feet, and easier movement over time.
Cardiovascular Wellness
Support for blood pressure
Nattokinase has been studied for supporting blood pressure levels already within the normal range. Meguri delivers it at 10,000 FU — the dose used in that research.
Inflammation Response
Turmeric and bromelain, working together.
Turmeric and bromelain have been traditionally paired for centuries in Japan to support the body's natural inflammatory response — rounding out Meguri's formula to support your system from more than one angle.

Questions? We’ve Got You Covered
How is Meguri different from regular nattokinase supplements?
Meguri contains nattokinase at 10,000 FU per serving — double the potency of most "high-potency" claims on the market, and in range with the doses used in the landmark research. Every batch is sourced through traditional Japanese fermentation methods and independently lab tested for potency, so the number on the label is the number in the capsule.
How does nattokinase support cardiovascular health?
Nattokinase is a fibrinolytic enzyme naturally derived from natto — fermented soybeans that have been part of Japanese tradition for over 1,000 years. Research suggests it helps support healthy fibrin levels in the bloodstream, which plays a role in maintaining healthy circulation. Meguri's 10,000 FU dose is formulated to support this process consistently, day after day.
What is FU and why does it matter?
FU stands for Fibrinolytic Units — the standard measurement of nattokinase enzyme activity. Higher FU means more potent fibrinolytic activity. Most brands stop at 2,000–5,000 FU. Meguri delivers 10,000 FU per serving, matching the dose used in the research everyone in this space actually cites.
When might I notice a difference?
Consistency matters more than speed here. Some people notice early signals — like warmer hands and feet — within the first few weeks. For circulation and cardiovascular support, the research typically measures results over 3+ months of consistent daily use, which is why we recommend sticking with it.
Is nattokinase safe?
Nattokinase has been part of the traditional Japanese diet for over 1,000 years and has a strong safety profile. As with any supplement, consult your healthcare provider before starting — especially if you're taking blood-thinning medication, scheduled for surgery, or pregnant or nursing.
Who shouldn't take nattokinase?
Anyone on blood-thinning medication, anyone scheduled for surgery (stop at least 2 weeks prior — confirm this window with a doctor), and anyone pregnant or nursing should consult their doctor before starting.
Can I cancel or change my subscription?
Yes — if you're on a subscription, you can pause, modify, or cancel anytime with no penalty. Just contact us by email and we will process your request.
