Our take on the Swanson Vitamins Nattokinase

Swanson Nattokinase is a single-ingredient enzyme supplement sold in capsules, marketed for circulatory support. Each bottle holds 30 servings, so a bottle lasts about a month at the usual one-capsule daily dose. At $14.09 at iHerb as of November 4, 2026, it sits at the low end of its recent price range across the four stores that carry it new.

Questions and answers

Is Swanson Nattokinase worth it?
It is one of the cheaper nattokinase capsules around, at $14.09 at iHerb as of November 4, 2026. If you want a plain single-ingredient enzyme supplement and your doctor is fine with it, the price is hard to beat.
How long does one bottle last?
The bottle has 30 servings. At one capsule a day, that is about a month.
Can I take it with blood thinners?
Nattokinase can affect clotting, so talk to your doctor before combining it with warfarin, aspirin or other anticoagulants. Do not start it on your own if you take any of these.
How does it compare with other nattokinase brands?
Swanson's main edge is price and simple formulation. Other brands may list enzyme activity units (FU) per capsule, which makes potency easier to compare; check the label if that matters to you.
When is the price lowest?
It has been near $14 across the four stores carrying it new. Watch for iHerb sitewide sales, which tend to be when the price dips below its usual level.
