Potent liquid for children, pets and elderly. Alcohol free. Glycerin based. Standardized to 18 % Oleuropein. Concentrated liquid is more potent than the capsules and works fast. Dr. McCain believes this and Colloidal Silver are two of the most important supplements to keep in your medicine cabinet! Adult dose: 2-3 droppers full with water 3 times a day if needed.
