Ray M, 54

"Dad had his first heart attack at 58 and my older brother's already on medication for it, so I've known this was coming for me. I'm at the age now where it sits in the back of my mind. Nothing dramatic — but I get pins and needles in my hands some mornings, and my legs feel heavy by the end of a day on my feet. I wanted to get ahead of it rather than wait for a bad result and be told to start taking something. Took me a while to work out most nattokinase is dosed at 2,000 and the people who know what they're doing want a lot more than that. This was the first one I found with the full dose already in it. Few weeks in and the pins and needles have eased off. Might be nothing. Feels like something."

How Does it Work?

Today, millions of people are searching for natural ways to support healthy circulation.

As we age, our body's natural clearing system can slow down. One side of that system forms fibrin — the protein mesh your blood uses to clot. The other side clears it away again once it's done its job. That clearing side runs mainly on one enzyme, plasmin, and it gets less support with every passing decade.

Nearly every heart conversation you've ever had was about cholesterol. Almost none of them were about the clearing side.

AltruaLab Nattokinase is a natural circulation support formula designed to help support your body's own fibrinolytic activity — the clearance side of the equation.

Here's what a healthy, active clearing system may support:

✅ Steady, smooth blood flow already within normal range

✅ Clearer pathways and improved overall circulation

✅ Natural energy levels and a lighter feeling throughout the day

AltruaLab's advanced formula contains:

🟤 10,000 FU of nattokinase per serving — five times what most bottles carry

🟤 8-in-1 advanced enzyme and botanical formula for targeted quality and purity

🟤 Gluten-free, dairy-free, and tree-nut-free

Nattokinase is an enzyme isolated from natto, a fermented soybean dish eaten in Japan for over a thousand years. It was identified in 1980 by Dr Hiroyuki Sumi, who tested 173 different foods before he found it — looking for one that supported the body's own clot-clearing system.

Why 10,000 FU?

FU stands for Fibrinolytic Units. It measures enzyme activity, not weight — which matters, because activity degrades over time and a milligram figure on its own tells you nothing.

Most nattokinase on the shelf is dosed at 2,000 FU. Some reach 4,000 or 8,000. Meanwhile people who've researched this properly have been buying bulk powder and filling their own capsules to reach around 10,800 FU a day, because nothing on the market went high enough.

We built to that number. A full 10,000 FU in one three-capsule serving.

And because independent testing has found that some nattokinase products deliver well under what their label claims — one delivered less than half — every lot of ours is third-party tested so the number on the bottle is the number in the capsule.

What to Expect

This isn't an overnight product and we won't pretend otherwise.

Most people take it daily for a few weeks before they notice anything. What they tend to notice first is small and physical: warmth returning to hands and feet, legs feeling lighter at the end of the day, a general sense of things moving more easily.

Some people feel a shift within days. Some feel nothing they can name and keep taking it anyway. Both are normal.

Two capsules daily. One bottle is 30 servings,

A simple way to stay proactive

Once I hit my forties, I started paying more attention to the small habits that help me feel like I’m looking after myself. I did not want a cupboard full of complicated products—just something straightforward I could add to my morning routine. I liked that Altrua Labs clearly states the 10,000 FU serving and gives you an 80-day supply. Three capsules with my usual routine feels manageable, and I like knowing I’m making time for my everyday wellbeing even on busy weeks.

Thoughtful details make a difference

I have tried enough supplements over the years to know that the label matters. I was looking for a nattokinase product with a clearly stated 10,000 FU serving, a longer supply, and ingredients I could review for myself. This one ticked those boxes. I like that it fits into my daily habits without making a fuss. It is one small, practical way I can support my wellness goals while I keep doing the things that make me feel like myself.

Mark K. Verified customer

A routine I can actually stick with

After a health conversation that got my attention, I wanted to be more intentional about my everyday choices. I still follow the guidance my healthcare team gives me, but I wanted a wellness routine that felt like mine too. Altrua Labs has been easy to keep up with and its just three capsules, a clear serving, no dramatic promises. I take it as part of the routine I’m building around walking, better meals, and staying active for the people I love.

I appreciate knowing what I’m taking

I’m the person who reads every label before I buy anything. What stood out to me was the clear nattokinase potency and the fact that the supporting ingredients are listed right there. I also appreciated the vegetarian capsules and the straightforward supply size, because I hate having to re-order something every few weeks. It has become a steady part of my wellness routine, and that consistency gives me a little more peace of mind.

Daniel T. Verified customer

It helps me feel on top of my routine

At this stage of life, I care less about miracle claims and more about doing the sensible things consistently. I stay active, make my appointments, and pay attention to what I take. Altrua Labs appealed to me because the serving is clearly explained and the bottle lasts long enough for me to make it a proper habit. It has earned a place on my kitchen shelf, right alongside the other everyday choices that help me feel prepared and engaged in my own wellbeing.

FAQ

Can Altrua Labs help with cold hands and feet or heavy legs? +

Those are the two things customers mention most. Nattokinase supports your body's own fibrinolytic activity — the clearing side of healthy circulation — and healthy blood flow is what carries warmth out to your extremities. It's not a treatment for any condition, and if those symptoms are new or worsening, get them looked at.

How long until I notice a difference? +

Most people take it daily for two to four weeks before anything registers. A few notice something in days. Some feel nothing they can name and keep taking it anyway. One bottle is 30 servings.

How is Altrua Labs different from other Nattokinase? +

Two things. Dose — most bottles stop at 2,000 FU, and people who've researched this have been compounding their own capsules to reach around 10,800 a day. We put a full 10,000 FU in one two-capsule serving. And verification — independent testing has found nattokinase products delivering well under their labelled activity, one at less than half. Every lot of ours is third-party tested.

Why hasn't my diet or my statin covered this? +

Because they work on a different part of the picture. Cholesterol is one input. Fibrin balance — how your body forms and clears the mesh that lets blood clot — is a separate process, and it's the one nobody mentions. This isn't a replacement for anything your doctor has prescribed.

Can I take this with my current medications? +

Ask your doctor first, and be specific if you're on a blood thinner — warfarin, Eliquis, Xarelto, or daily aspirin. Nattokinase has its own mild effect on blood, so stacking them can add up. Same conversation if you have a bleeding disorder, a mechanical heart valve, or surgery or dental work coming up — stop at least two weeks before any procedure.

What ingredients are in the formula? +

Nattokinase from natto extract at 500 mg and 10,000 FU, plus a 500 mg blend of CoQ10, turmeric, dandelion root, aged garlic and grape seed, with bromelain at 10 mg and pine bark extract at 5 mg. Other ingredients are rice flour, magnesium stearate, silicon dioxide and a vegetable cellulose capsule.

Is the formula clean and allergy-safe? +

Free from gluten, dairy and tree nuts. It contains soy — nattokinase is fermented from soybeans, so if you're soy-allergic this isn't for you. Made in a cGMP facility, non-GMO.

How should I take it? +

Take exactly 2 vegetable softgels daily with a full glass of water. You can take one in the morning, one at lunch or one at night for a full 24-hour coverage.

What if the supplement doesn't work for me? +

Take it daily for 30 days. If you don't notice a difference in how you feel, email us for a full refund. You don't need to send the bottle back.

Can I buy Altrua Labs products in retail stores? +

No. To cut out middleman markups and guarantee absolute batch freshness, Altrua Labs is available exclusively through our website. Every batch undergoes strict third-party laboratory verification for safety, heavy metals, and purity.

"My brother went down at 57 in his own driveway. He's fine now but I'm 55 and I've thought about it every day since. Spent a fortnight reading forums and worked out most bottles are dosed at 2,000 while everyone serious wants five times that. This was the first one I found that just had it. Month in, my feet aren't blocks of ice when I get up."
