OK Kosher Certified
Issued by OK Kosher Certification (OK Labs)
CertificationAudit Scope
Rabbinic supervision of ingredient sourcing, equipment use, production schedule, and final product. Annual on-site inspections. One of the 'Big Five' U.S. kosher certifying agencies with significant supplement-industry presence.
What It Proves
Rabbinic authority confirms ingredients, equipment, and process meet OK Kosher kashrut standards. Certification verifiable via OK Kosher's public company database.
What It Does Not Prove
Does NOT mean the product is halal, vegan, organic, or gluten-free — separate certifications required. Different kosher agencies (OU, OK, Star-K, Kof-K, CRC) have slightly different standards and are not always interchangeable in specific dietary contexts. 'Kosher' alone (without an agency mark) is unverifiable.
