Description
Swanson Maximum Strength Nattokinase is formulated to deliver twice the potency of standard nattokinase in a single daily capsule. Nattokinase is a fibrinolytic enzyme produced during the fermentation process used to make natto, the traditional Japanese soybean dish, and its activity is measured in fibrinolytic units (FU) rather than milligrams alone. Research suggests that fibrinolytic enzymes like nattokinase help promote healthy blood flow, which is why nattokinase is commonly researched alongside circulatory and cardiovascular health.
What's in each capsule
Each capsule provides 200 mg nattokinase, standardised to 4,000 fibrinolytic units of activity. Other ingredients are maltodextrin, microcrystalline cellulose (plant fibre), gelatin, magnesium stearate and medium-chain triglycerides from palm oil. Because the capsule contains gelatin, this product is not suitable for vegetarians or vegans.
Why the higher strength matters
Most single-ingredient nattokinase products on the market use 100 mg per capsule to reach 2,000 FU, which usually means taking two capsules to get a 4,000 FU dose. This Swanson formula reaches the same 4,000 FU in one 200 mg capsule and one daily dose, which can suit people who prefer the simplest possible routine over splitting servings across the day. It is worth remembering that FU reflects standardised enzyme activity rather than a simple doubling of milligrams, which is why the label lists both figures together.
Who this suits
If you have already researched nattokinase and decided a higher FU strength suits your routine, this is a straightforward way to get there without adding extra ingredients or a twice-daily schedule. If you are new to nattokinase, it may be worth starting with a more common 2,000 FU strength and comparing how it suits you first, since higher strength is not automatically the right starting point for everyone.
How to use it
As a food supplement, take one capsule per day with water. This product is for adults only. Consult your healthcare provider before use if you are pregnant or nursing, have a medical condition or are taking medication, especially blood-thinning medication.

Storage
Keep out of reach of children, do not use if the seal is broken, and store in a cool, dry place.
