Lisinopril and Olive Leaf Extract, a synergy.
Olive Leaf Extract lowers blood pressure (about 4-11 mm Hg systolic depending on dose) and was non-inferior to captopril for stage 1 hypertension in one randomized trial. Combined with lisinopril the effects are additive and generally well tolerated, though mild hypotension is possible if blood pressure is already at goal.

Synergy
What is happening. Olive Leaf Extract lowers blood pressure (about 4-11 mm Hg systolic depending on dose) and was non-inferior to captopril for stage 1 hypertension in one randomized trial. Combined with lisinopril the effects are additive and generally well tolerated, though mild hypotension is possible if blood pressure is already at goal.
Mechanism. Oleuropein and related polyphenols in olive leaf inhibit ACE activity, improve endothelial nitric oxide bioavailability, and reduce vascular oxidative stress. These actions complement lisinopril.
Recommendation. Olive Leaf Extract 500-1000 mg/day is a typical research dose. Monitor home blood pressure after starting and tell your prescriber so your lisinopril dose can be reviewed.
