Buying advice

When choosing olive leaf supplements, prioritize standardized extracts with at least 6% oleuropein for effectiveness. Consider dosage form (capsules vs liquid) and any dietary restrictions (e.g., vegetarian, hypoallergenic). Higher potency (1000mg) may be better for immune support, but start with lower doses to test tolerance. Check third-party testing for quality assurance.
