Nattokinase Australia

Nattokinase is an enzyme isolated from natto, the fermented soybean food, and it is dosed in fibrinolytic units (FU) rather than milligrams. That is the number to compare: two products can both say "100 mg" and deliver very different enzyme activity.

The range here spans the common daily strengths from 2,000 FU up to 10,000 FU high-potency capsules, including vitamin K2-free versions for people who have been told to keep K2 separate, and combination formulas that pair nattokinase with serrapeptase or bromelain. Each listing states the FU per capsule and the serving size.

Most nattokinase is supplied from Japanese-fermented raw material regardless of where the capsule is packed, and the manufacturers here publish their source. Prices are in AUD, shipped Australia-wide with tracking.

Nattokinase Australia — frequently asked questions

What does FU mean on a nattokinase label?

Fibrinolytic Units — a measure of enzyme activity. It is the meaningful comparison between products; the milligram weight of the capsule contents is not, because carrier material varies.

What is the difference between 2,000 FU and 10,000 FU?

Enzyme activity per serving. Lower strengths are typically taken as a daily maintenance dose and higher strengths less frequently. Follow the manufacturer's stated serving and speak to your pharmacist or doctor, particularly if you take blood-thinning medication.
