Oleuropein is a polyphenol in olive leaves and olive oil. Its antioxidant and anti-inflammatory actions may help shield cells from oxidative stress.
Oleuropein promotes heart health by helping keep blood pressure and cholesterol in the normal range. It also strengthens immune function by adjusting the body's natural defenses.
Olive leaf extract provides the oleuropein in supplements. Take it with meals for better absorption. Products come standardized to a specific oleuropein content. Follow the dosage directions on the label.
Some people notice mild stomach upset. Because oleuropein can gently lower blood pressure and thin the blood, talk to a doctor before using it alongside blood pressure or blood-thinning medications.
