Questions and answers

Is 4000 FU a high dose of nattokinase?
Yes. Many nattokinase capsules are 2000 FU, so 4000 FU is double that in one capsule. Typical studied ranges run from 2000 to 4000 FU per day, so check with a doctor before going higher.
Can I take this with blood thinners?
Nattokinase can increase bleeding risk, so talk to a doctor first if you take warfarin, aspirin or other anticoagulants. Stop before surgery as well.
Is it vegetarian and gluten-free?
Yes. The capsules are vegetarian, gluten-free and non-GMO, and the enzyme comes from fermented soy.
How many capsules are in a bottle?
The listing does not state the capsule count, so confirm the bottle size before ordering. At one capsule per serving, a 90-count bottle lasts about three months.
When is the best time to buy it?
The best new price is $19.99 at Walmart as of November 4, 2026. Nattokinase is a steady seller, so watch for multi-bottle bundles rather than deep discounts.
