  • For faster results, towel dry hair to remove excess water, then run a comb through damp hair to detangle for best results.


  • Separate hair into manageable sections.


  • For smooth blowouts, place the Volumizer close to the roots and brush down toward the ends. The mixed nylon-pin with rounded tips quickly while tufted bristles with boar technology gently grip hair to smooth out hair.


  • ​For voluminous blowouts, place the Volumizer under the hair close to the roots and roll outward to the ends. For Extra lift at the roots, hold the Volumizer for 2 to 3 seconds under the roots.


  • ​To curl ends IN, place the Volumizer UNDER the ends and hold or 2 to 3 seconds before rotating inward. To curl ends OUT, place the Volumizer OVER the ends and hold for 2 to 3 seconds before rotating outward.

This is truly the greatest thing since sliced bread


I've put off buying something like this for years, but finally I gave in with a great deal of trepidation. I shouldn't have waited so long!

Unbelievable easy and I didn’t even have to go back over it with a flat iron!


I can’t wait to dry my girls hair after a nighttime bath too. I almost never write reviews but thanks to this magical thing I had the time!

Fibrin buildup. Years in the making.

Fibrin builds up for years. You feel nothing. Your checkup catches nothing.

After 30, your body slowly stops clearing the buildup.4 You won’t feel it. Your cholesterol won’t catch it. Your blood pressure won’t either. Most nattokinase stops at 2,000 FU, a fifth of the dose the research everyone quotes. Ours is 10,800 FU.

Black Forest Nattokinase 4-in-1

THE FULL CLEAN-UP CREW.

Healthy vs sluggish circulation
1

Nattokinase, 10,800 FU. Supports your body’s own breakdown of fresh fibrin, the clean-up it has run slower every decade since your twenties.4*

2

Serrapeptase, 180,000 SPU. Supports how your body clears the inflammatory debris a single-enzyme formula leaves behind.*

3

Lumbrokinase, 40 mg. Built for the older, hardened buildup single-enzyme formulas miss.* It costs more than the other three put together, so the shelf skips it.

4

Vitamin K2 as MK-7, 180 mcg. Routes calcium toward your bones, away from your artery walls.*

Four actives. One capsule. Until now, this stack didn’t exist in a single US bottle.

SIX REASONS THIS ISN’T ANOTHER NATTOKINASE PILL.

Most nattokinase stops at 2,000 FU. A fifth of the dose the research everyone quotes.

Avoid generic single-enzyme nattokinase
01

10,800 FU. Not 2,000.

The dose in a 1,062-person, 12-month study.1 Most bottles deliver a fifth of it, next to a label that name-drops the same study. We didn’t cut it.

02

Four actives, not one.

Nattokinase, serrapeptase, lumbrokinase and vitamin K2. Every one printed on the label with its own number next to it. Soy-free fermentation, so no soy protein residue reaches the capsule.

03

Enteric-coated.

Nattokinase is a protein. Stomach acid digests protein. The coating carries all four past it, so the label is what arrives.

04

K2 at the trial dose.

180 mcg of MK-7, the exact dose from a 3-year randomized trial in 244 postmenopausal women.2 It routes calcium toward bones and away from arterial walls.*

05

Lab-tested at every lot.

GMP Certified · FDA-Registered Facility. Potency verified at every lot release: FU, SPU, mg and mcg. Almost nobody on the shelf publishes theirs. Ask.

06

44 cents a day.

One capsule. 60 capsules is a two-month bottle. Six months for $79.92, or 4.1 cents per 1,000 FU.

No single-enzyme half-measures. No fairy-dust doses. Four clinical enzymes, one capsule.

The buildup, and the man who found the enzyme

THE BUILDUP NOBODY SCREENS FOR.

Your body lays down fibrin every day and is supposed to clear it again. When it doesn’t, the leftovers stay. Old fibrin circulates for years. No symptom. Nothing on a cholesterol panel.4

Chicago, 1980. Hiroyuki Sumi drops natto, a thousand-year-old Japanese breakfast, onto a dish of human fibrin. He comes back 18 hours later. The fibrin is gone. He named the enzyme nattokinase.

Japan spent four decades studying it. Japan’s cardiovascular death rate runs at roughly half of ours.5 Same wealth. Same hospitals. Half.

Here at home, your clean-up slows every decade after 30 while the fibrin keeps coming.4 Statins work on cholesterol. Blood thinners work on new clots. Neither was built for what’s already circulating. And nobody in the system gets paid when your blood clears on its own.

Before you compare bottles: nattokinase is measured in fibrin units, FU, not milligrams. Same milligrams can mean nothing alike.

A thousand years on a Japanese breakfast table. Almost none of it in your doctor’s chart.

Nattokinase and healthy arterioles
🩸

Healthy blood-clearing*

Nattokinase at 10,800 FU supports your body’s breakdown of fresh fibrin. Serrapeptase at 180,000 SPU supports clearing the debris left behind.*

🔄

Circulatory support*

Supports healthy circulation as your body’s own clearing slows with age.4 Enteric-coated, so the label is what arrives.*

🦴

Arterial calcium balance*

K2 as MK-7 at 180 mcg, the dose from the 3-year trial, routes calcium toward bones rather than arterial walls.2*

❤️

Cardiovascular function*

Supports healthy cardiovascular function, with lumbrokinase at 40 mg for the older buildup single-enzyme formulas miss.*

The Dose

10,800 FU. 1,062 people. 12 months.

A 12-month study of 1,062 participants used nattokinase at 10,800 FU a day. It was retrospective, not randomized and not controlled, so it cannot show that nattokinase causes anything, and we claim no outcome from it. We cite it for one fact. The dose. Ours.1*

The K2 Evidence

180 mcg. Three years. Randomized.

244 healthy postmenopausal women took 180 mcg of MK-7 a day for three years in a double-blind, placebo-controlled, randomized trial. That is the exact K2 dose in this capsule. Studied in postmenopausal women, so read it for what it is: the strongest dose evidence in the formula.2*

The Hands

Warmer hands than placebo.

In a double-blind, placebo-controlled, randomized crossover trial, 9 healthy men took a single 2,000 FU dose. In the authors’ words, skin temperature of the middle finger, palm and back of the hand was “significantly higher during the recovery period after NK supplementation than after the placebo” (p<0.05). Nine men is a small study. We’d rather say so than let you find it.3*

Here’s the deal:

Tiny fragments of old fibrin circulate in your blood for years. Standard screening doesn’t look for them. After 30, your body clears a little less of them every year, and a little more stays.4

You won’t feel it. Your cholesterol won’t catch it. Your blood pressure won’t either.

And nobody in the system gets paid when your blood clears on its own. A thousand-year-old food can’t be patented, so nobody funds the trial, nobody writes the guideline, and your doctor won’t say its name.

Most nattokinase on the shelf is one enzyme at 2,000 FU. A fifth of the 10,800 in the study everyone quotes.1 And the four-enzyme stack didn’t exist in a single US bottle.

So we built it.

We’re the team that sued the FDA over the 2022 NMN ban. And won. This is the same fight.

Black Forest Nattokinase 4-in-1 supplement facts

What you’ll actually feel.

The mechanism is the study. The experience is what the people who read the research keep writing us about.

Individual experiences vary and are not necessarily typical.

Out running in the morning
🔥

Warm hands and feet

The one thing here measured against placebo. Finger, palm and hand skin temperature ran higher after nattokinase than after placebo in a randomized crossover of 9 men.3 Judy in Harlan, Iowa, her own words: “I don’t get cold as easy…”*

⚡

Clean energy, no spike

No stimulant in this capsule, so nobody is describing a hit. Five separate reviewers wrote about energy anyway. Michelle: “more energy, sleeping better.” Edwin: “more pumped and energized during workouts.” Dale, Nicarlos and William, their own versions of the same thing.

🏃

Stamina that holds

Judy again: “my stamina in my daily exercise is good even in the Iowa heat and humidity…” Dale in Madison, Alabama takes his first thing, “before my morning workout.”

📋

Something to watch at your next check-up

Enzyme support runs on months, not mornings. Warren in San Jose, 45 days in: “The real test will [be] in November when I go for my annual check up and blood test…” He isn’t claiming a result and neither are we. Take it daily and let your doctor read the numbers.

What to expect.

A grey-bearded man in his late fifties running along a waterfront railing in cold weather, beanie and gloves on.
First 2 hours
  • The enteric coating holds the capsule shut through your stomach acid and opens it further down. That’s the difference between an enzyme you absorb and one you digest.
  • Nattokinase and serrapeptase begin supporting the fibrin clean-up your body already runs.*
  • The only same-day effect anyone has measured against placebo was warmth. Finger and palm skin temperature ran higher than placebo after a single 2,000 FU dose, in a crossover of 9 men.3*
  • Nine men is a small study, and you probably won’t feel a thing today. We’d rather say so than let you find out on your own.
First week
  • One capsule with breakfast. That’s the entire routine.
  • Clearing fibrin is housekeeping your body already runs every day, on buildup you never feel. These enzymes work alongside it.4*
  • Nothing stockpiles, so a skipped day is just a day without it.
  • Charles in Phoenix, a few days in: “I actually do feel more energetic, but that could also be due to my sleeping aids.” That’s what week one usually sounds like.
First month
  • Continued support for healthy fibrin levels and healthy arterial walls.*
  • The far end warms up first. Your fingers and toes sit furthest from the pump, and warmth out there is the only felt change anybody has put up against a placebo.3*
  • The K2 runs on a second clock. Its job is where calcium ends up, bone rather than arterial wall, and it only does that job on the days you take it.2* You’ll never feel calcium being routed. Nobody does.
  • This is your decision window. Email us before day 30 and we refund you in full. Keep the bottle. Sixty capsules means you decide with a month still in the cupboard.

Dosed the way it should be

“I’m very impressed with the product because it is dosed the way it should be and the price point is amazing… I love that it has the 3 enzymes in it because they all work synergistically together and the vitamin k is another great bonus…”

Stephen D. · Plant City, FL

Hard pressed to find better

“This has all fibrinolytic enzymes you could ask for in an all-in-one dose, very nice!… you’d be hard pressed to find better on the Market, especially in an all-in-one supplement, that is taken once a day. Not mention the MK7 is like a cherry on top!!!”
