The science, in plain English

Two enzymes and two extracts, explained

An enzyme from a Japanese food, an enzyme from pineapple, and two spice extracts. Here is what each one is, and how it is measured.

Mechanism 01

An enzyme from fermented soybeans.

How it works

Natto is a traditional Japanese food of soybeans fermented with Bacillus subtilis natto. In 1987, researcher Hiroyuki Sumi identified an enzyme in it and named it nattokinase. Enzymes are measured by activity rather than weight: ours is 20,000 fibrin units (FU) per gram.

The everyday context
JapanFermented soybeansMeasured in FU
In two capsules

Worth knowing

From soybean to capsule

1

Soybeans

Glycine max

Whole soybeans are soaked and steamed.

2

Fermented

B. subtilis natto

They are fermented with Bacillus subtilis natto, a bacterium named after the food.

3

Natto

Japan

The result is natto: sticky, stringy and a breakfast staple in Japan.

1987

Sumi et al.

Researcher Hiroyuki Sumi identifies an enzyme in natto and names it nattokinase.

About Roundway

What if the best ideas come from the people taking them?

We grew up with parents who cared about nutrition and good food, and we’ve spent years listening to friends and practitioners who champion clean-label products. So we build the way we were taught to eat: start with what’s real, and leave out what isn’t needed.

That’s why every Roundway pack starts with what you ask for. Conversations at our talks and stands, messages in our inbox and your reviews shape what we make next, and how we label it.

Then we gave people a first look at our 2027 range. The feedback said it all: this is how supplements should be made.

Inside two capsules

Four ingredients, one daily serving

4,000FU nattokinase
  • 200mg nattokinase
  • 300mg bromelain
  • 300mg turmeric extract
  • 10mg black pepper extract

Two capsules a day. 60 capsules, 30 days.

Concentrated

What 50:1 actually means

Turmeric extract is concentrated 50 to 1: it takes about 50 parts of dried turmeric root to make one part of extract. Press the button to see the 300mg in two capsules come from about 15 grams of root.

Your routine

Two capsules, once a day

Take two capsules a day with a glass of water, at whatever time suits you. A pack holds 60 capsules, so it lasts a month.

Pick a moment you already have, like breakfast, so it becomes part of the day rather than something to remember.

Ready when you are.

Nattokinase, bromelain and curcumin, answered

How much nattokinase is in each serving?
Two capsules provide 200mg nattokinase at 20,000 FU per gram, which is 4,000 fibrin units (FU). Each capsule provides 2,000 FU.
What does FU mean?
FU stands for fibrin units, a measure of enzyme activity. Enzymes are labelled by activity as well as weight, because two powders of the same weight can have different activity.
What is nattokinase made from?
It comes from natto, a traditional Japanese food made by fermenting soybeans with Bacillus subtilis natto. It contains soy.
What is bromelain?
A group of enzymes from the stem and fruit of the pineapple. Two capsules provide 300mg at 2,400 GDU per gram, which is 720 GDU.
What does 50:1 turmeric extract mean?
It takes about 50 parts of dried turmeric root to make one part of extract. The 300mg in two capsules comes from about 15g of root and is standardised to 95% curcumin, giving 286mg curcumin. It is paired with 10mg black pepper extract (95% piperine).
Can you take nattokinase and bromelain together?
Yes. This formula combines them in one daily serving: two capsules provide 200mg nattokinase (4,000 FU) and 300mg bromelain (720 GDU), alongside turmeric and black pepper extracts. If you take any medication, including anticoagulants or antiplatelet medicines, speak to your GP or pharmacist first.
Can I take it if I am pregnant, breastfeeding or on medication?
If you are pregnant or breastfeeding, take any medication, including anticoagulants or antiplatelet medicines, or have a medical condition, speak to your GP or pharmacist first.
Who makes it?
Roundway, a British brand based in Wiltshire. It is produced in a GMP (Good Manufacturing Practice) certified facility.
