Our verdict
NOW Supplements, Nattokinase 100 mg (from Non-GMO Soy) with 2,000 FUs… works out to $0.25 per serving of nattokinase, at 100mg per serving in capsule form. That puts it below the median of the 29 nattokinase products we can price per dose, where the typical serving costs $0.27, a Value Index of 1.1 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $7.50 a month. We could not verify a third-party certification for NOW in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
