Olive Leaf Extract Liquid 1500mg 20% Oleuropein - Immune Support

In this review the Olive Leaf Extract liquid is evaluated as a concentrated, once-daily herbal supplement for anyone seeking immune and antioxidant support without swallowing pills. The bottom line: this product is best for people who want a high-potency, vegetarian, non-GMO olive leaf extract delivered as a liquid that is easy to dose and manufactured in a cGMP facility in the United States. The single biggest reason to buy is the strong 1500mg serving standardized to 20% oleuropein, which provides a measurable concentration of the primary active polyphenol.

Key Features

• High potency: Each serving supplies 1500mg of olive leaf extract standardized to 20% oleuropein for concentrated polyphenol delivery.
• Vegetarian and non-GMO: The formula uses non-gmo leaf material and vegetarian ingredients for customers avoiding animal-derived additives.
• Liquid convenience: Offered as an 8 fl oz liquid extract so users can measure a single daily dose instead of taking multiple capsules.

The product will also appeal to shoppers wanting vegetarian and non-GMO sourcing and domestic manufacturing.

It may be less appropriate for consumers who want multi-ingredient blends (for example combined vitamins) or who prefer capsules for travel convenience. Anyone with medical conditions or on medication should consult a physician before starting this or any dietary supplement.
