Key health benefits

Research into the efficacy of olive leaf is ongoing - below is a summary of the effects scientists have studied.

Antioxidant effects

• Olive leaf compounds help neutralise free radicals, protecting cells from oxidative stress.
• This may lower the risk of chronic diseases linked to inflammation and oxidative damage.

Supports heart health

• May reduce blood pressure by improving blood vessel function.
• Can help lower LDL ('bad') cholesterol and triglycerides while raising HDL ('good') cholesterol in some studies.
• Supports healthy circulation and vascular function.

Blood sugar regulation

• May improve insulin sensitivity and help regulate blood glucose levels, which could benefit people with type 2 diabetes or metabolic syndrome.

Antimicrobial properties

• Olive leaf compounds have antibacterial, antiviral and antifungal effects.
• Supports immune health and fights infections.

Anti-inflammatory activity

• Oleuropein helps reduce inflammation which may ease conditions like arthritis or general inflammatory stress.

Neuroprotection

• Antioxidants in olive leaf may help protect brain cells against damage, with some research suggesting benefits for memory and cognitive decline.
