1. Boosts immune system: Olive leaf extract contains powerful antioxidants and compounds that help strengthen the immune system and fight against harmful bacteria and viruses. Regular consumption of this product can help reduce the risk of infections and illnesses.
2. Lowers blood pressure: The active ingredient in olive leaf extract, oleuropein, has been shown to have a positive effect on blood pressure by relaxing the blood vessels and promoting better circulation. This can help lower blood pressure and reduce the risk of heart disease and stroke. Additionally, the antioxidants in olive leaf extract can also help reduce inflammation, which is a major contributor to high blood pressure.

The Active Ingredient Is: Oleuropein (from Olive Leaf Extract)

Oleuropein is basically the polyphenol behind olive leaf extract's bioactive properties. This ingredient is naturally found in olive leaf and is concentrated in the extract used in this product. The formulation is standardised to 15 percent oleuropein to provide a potent polyphenol content.

Source material is olive leaf extract, supplied in a vegan capsule. This active component is expressed as oleuropein within the extract and reflects the product's focus on olive leaf polyphenol content as a primary active constituent.

What Does Oleuropein Do?

Oleuropein participates in antioxidant activity and is associated with immune support and cardiovascular-friendly effects in human studies. This aligns with EFSA-type function claims describing polyphenols as contributors to antioxidant protection and immune balance.

Research suggests that olive leaf polyphenols may support vascular function and lipid balance, with effects noted in cardiovascular-related contexts. Dr. Lockyer of University found evidence indicating antioxidant benefits linked to oleuropein-rich olive leaf extracts.
