Frequently Asked Questions
Q: Is 450mg per capsule too high a dose?
A: 450mg is a therapeutic dose appropriate for active immune challenges or clinical protocols. For daily maintenance, 1 capsule/day may suffice; for active infections, 2–3 capsules per day are commonly used under practitioner guidance.
Q: What does standardized mean for olive leaf?
A: Standardization ensures a consistent percentage of oleuropein (the primary active) in every batch — typically 15–20% oleuropein for quality products. This ensures reliable potency regardless of natural variation in raw material.
Q: Should I cycle olive leaf extract?
A: Some practitioners recommend periodic cycling (weeks on, weeks off) to prevent adaptation of gut microorganisms. Others use it continuously. Consult your practitioner for your specific protocol.
