Specialty · 4000 FU serving
Double Wood 4000 FU
Each capsule is commonly 100 mg / 2,000 FU. The listing serving is 2 capsules = 4,000 FU (120 count / 60 servings). Shortlisted as the higher-FU caution lane — not a CytoDaily default daily. Kitchen-sink 10,000 FU blends stay off.

Listing snapshot
Why it is on the shortlist
The fourth milligram-style step is a serving, not a mystery mega-blend. Map: Nattokinase. Softgel NSK-SD: Allergy Research NSK-SD.
Boundaries
Higher FU is not a clot clinic. Anticoagulants, bleeding, and surgery remain hard stops. Do not stack this 2-capsule serving on top of another 2,000 FU bottle.
