Kof-K Kosher Certification
Issued by Kof-K Kosher Supervision
CertificationAudit Scope
Rabbinic supervision of ingredient sourcing, facility, equipment, and production. Periodic on-site inspections. One of the 'Big Five' U.S. kosher certifying agencies with significant supplement-industry presence.
What It Proves
Kof-K Kosher Supervision confirms the product, its ingredients, and the production facility meet Kof-K kashrut standards. Verifiable via Kof-K's product database.
What It Does Not Prove
Does NOT mean the product is halal, vegan, organic, or gluten-free. Distinct from other kosher agencies (OU, OK, Star-K, CRC) — standards have minor variances that may matter in specific dietary contexts. 'Kosher' alone (without agency mark) is unverifiable.
