Source Naturals NSK-SD
Nattokinase as trademarked NSK-SD — commonly 100 mg / 2,000 FU per vegan capsule, 60 count. Shortlisted as the named patented-form veg-cap lane, not as a higher dose. Label often suggests up to three capsules daily on an empty stomach; do not treat that as CytoDaily’s default. Still soy. Still not food natto.
Affiliate link via /go/natto-sn-nsksd (ASIN B000GFJK96). Prefer Amazon.com or the brand-authorized seller. Confirm NSK-SD 100 mg (2,000 FU) vegan caps, 60 count — not the 30-count pack as a new lane. Not medical advice.

Listing snapshot
Why it is on the shortlist
Same 2,000 FU job as Doctor’s Best, different named material (NSK-SD). Replaces the delisted Nature’s Answer Amazon SKU on this lane. Map: Nattokinase. Higher listed serving: Double Wood 4,000 FU serving.
Boundaries
Fibrin / circulation folklore stays on the listing. CytoDaily does not treat clots. Clinician first if you take blood thinners or have cardiovascular disease.
