Clinical Trials Shift Olive Phenolics Toward Glucose and Lipid Claims
Clinical trials on hydroxytyrosol and oleuropein are moving beyond antioxidant markers toward glucose response, blood pressure, and lipid outcomes, giving brands the evidence needed for dose-defined products. Studies in Spain, Italy, and Australia have used daily doses between 5 and 30 milligrams, and supplement makers now design capsules and powders around those ranges. Suppliers that fund trials and publish dossiers gain pricing power, and buyers increasingly demand batch-level potency verification before signing annual supply contracts. Brands also use trial results in retailer negotiations, which shortens listing cycles and supports higher shelf prices for products that carry defined doses.
Market Impact: claim requires 5 mg per 20g
