  • Started this for cold hands and feet that kept getting worse. The nattokinase plus garlic extract combo seemed like the most complete option out there. A few months in and my circulation genuinely feels better — way fewer cold, numb mornings.

  • Recovery has always been my weak point. I'd train hard and then be sore for days. Started using both cups on my back and shoulders after every heavy session and the difference in how fast I bounce back is noticeable. The red light glow looks insane too — feels like actual professional equipment. Worth every penny.

  • Wanted something proactive for cardiovascular wellness since it runs in my family. Like that it's not just nattokinase alone — the aged garlic and CoQ10 combo is backed by real research for vascular health. Feels like a more complete formula than the single-ingredient options.

    Product Details

    For over 2,000 years, the Japanese have eaten natto — a fermented soybean dish — as part of their daily diet, long linked to some of the longest lifespans in the world. Nattokinase is the enzyme responsible, first isolated by Japanese researcher Dr. Hiroyuki Sumi in 1987.

    Each serving of Tuviki Nattokinase delivers 10,000 FU (fibrinolytic units), paired with four supporting ingredients traditionally used for heart and circulation wellness: CoQ10, bromelain, turmeric, aged garlic extract, and pine bark extract.

    This product is a dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease.

    Why This Formula Works

    Nattokinase (10,000 FU) — One of the highest-potency doses available, studied for its role in supporting healthy blood flow and fibrinolytic activity.

    CoQ10 + Aged Garlic Extract — A year-long clinical trial found this combination was associated with improvements in vascular elasticity and endothelial function — the cells lining your blood vessels.

    Turmeric — Traditionally used for its antioxidant properties, helping combat everyday oxidative stress.

    Bromelain — A natural pineapple-derived enzyme, commonly paired with nattokinase for added digestive and inflammatory support.

    Pine Bark Extract — A potent antioxidant traditionally used to support healthy circulation and vascular function.

    How to Use

    Take 3 capsules daily with food, or as directed by your healthcare provider.

    Each bottle contains 240 capsules (80 servings) — roughly a 2.5 to 3 month supply.

    ⚠️ Important: Avoid use if you have a history of ischemic stroke, peptic ulcers, or coagulation disorders, or if you have upcoming surgery. May increase bleeding risk if combined with blood thinners or antiplatelet medication. Consult your doctor before use if pregnant, nursing, or on any medication.

    Support Your Heart. Naturally. Every Day.

    A Formula Built on 35+ Years of Research

    Nattokinase isn't a new trend — it's been studied since 1987, when Japanese researcher Dr. Hiroyuki Sumi first isolated it from natto, a traditional fermented soybean dish eaten for over 2,000 years. Each capsule delivers 10,000 FU, one of the highest potencies available, so you're not just taking "a little nattokinase" — you're taking a clinically meaningful dose.

    Heart Support That Goes Beyond One Ingredient

    Single-ingredient supplements only tell half the story. This formula pairs nattokinase with CoQ10 and aged garlic extract — a combination shown in a year-long clinical trial to improve vascular elasticity and endothelial function, the cells lining your blood vessels. You're not betting on one enzyme alone.

    Antioxidant Protection From the Inside Out

    Turmeric and pine bark extract aren't filler ingredients — both are well-studied antioxidants traditionally used to fight everyday oxidative stress and support healthy circulation. Not a gimmick — the same combination found in clinical-grade cardiovascular formulas, now in one capsule.

    240 Capsules. Built to Last.

    No constant reordering, no running out at the worst time. One bottle covers 2 to 4 months depending on your daily serving size, so your routine stays consistent without the constant restock hassle.

      Your Body Is Telling You Something

      Most people accept cold hands, low energy, and sluggish afternoons as just "getting older." But if you're only reaching for coffee or ignoring it, you're masking the problem, not addressing it. Every day without proper cardiovascular support is another day your circulation has to work harder than it should.

      You Know The Feeling

      The cold fingers that take forever to warm up. The afternoon crash that hits no matter how much you slept. The nagging feeling that your "normal" lab results don't match how sluggish you actually feel. That's not just aging — that's your body asking for more support than diet alone can give it.

      The Easiest Heart Health Upgrade You'll Make

      Take it with breakfast, and let the formula do the work. No appointments, no expensive specialist visits, no complicated regimen. Just one capsule, once or twice a day, built on research that goes back decades.

      Finally, Circulation Support That Actually Goes Deep

      Most supplements give you one ingredient and call it support. This isn't a single-strain pill — it's a 5-in-1 formula combining nattokinase, CoQ10, aged garlic extract, turmeric, and pine bark to support your cardiovascular system from multiple angles at once.

      What is nattokinase and where does it come from?

      Nattokinase is an enzyme derived from natto, a traditional Japanese food made by fermenting soybeans with a specific bacteria strain. It was first isolated by researcher Dr. Hiroyuki Sumi in 1987 and has been studied for over 35 years.

      How much nattokinase is in each capsule?

      Each serving (3 capsules) delivers 500mg of nattokinase, providing 10,000 FU (fibrinolytic units) — one of the highest potencies available, well within the range used in published research.

      What are the other ingredients for?

      Each serving also includes a 500mg proprietary blend of CoQ10, turmeric extract, dandelion root extract, aged garlic extract, and grape seed extract, plus bromelain and pine bark extract — all traditionally used to support cardiovascular health and antioxidant protection.

      Is this safe to take with other supplements or medication?

      Nattokinase may increase bleeding risk when combined with blood thinners or antiplatelet medication. Avoid use if you have a history of ischemic stroke, peptic ulcers, or coagulation disorders, or if you have upcoming surgery. Always consult your doctor before starting, especially if you're on any medication.

        Noticeably less sluggish in the afternoons

        Started taking this with breakfast about two months ago. The full ingredient list — nattokinase plus CoQ10, garlic, grape seed — sold me since it wasn't just one ingredient. My afternoon energy crashes have gotten way less intense. Easy to swallow, no aftertaste.

        Cold hands issue has actually improved

        I've dealt with cold, numb fingers for years and finally decided to try nattokinase after some research. This one had the highest FU count I could find at a reasonable price. A few months in and my circulation genuinely feels better.

        Bottle lasts a solid 3 months, great value

        At 3 capsules a day this lasted me almost 3 months, which makes the price feel really fair. Take it with my morning coffee and haven't had any stomach issues. Like that it has turmeric and pine bark extract in there too for the antioxidant support.
