Coenzyme Q10 and Ramipril, a synergy.
Coenzyme Q10 lowers blood pressure modestly through improved endothelial function and reduced oxidative stress. A meta-analysis of 12 clinical trials reported meaningful systolic reductions. Combined with an ACE inhibitor like ramipril, the effect is generally additive and well tolerated, which can help patients with residual hypertension or heart failure.

Synergy
What is happening. Coenzyme Q10 lowers blood pressure modestly through improved endothelial function and reduced oxidative stress. A meta-analysis of 12 clinical trials reported meaningful systolic reductions. Combined with an ACE inhibitor like ramipril, the effect is generally additive and well tolerated, which can help patients with residual hypertension or heart failure.
Mechanism. CoQ10 improves mitochondrial function in vascular smooth muscle and endothelium and reduces oxidative inactivation of nitric oxide, complementing ACE inhibition.
Recommendation. If your blood pressure is well controlled on ramipril alone, monitor at home before adding CoQ10. A typical dose is 100-200 mg/day with a fat-containing meal. Recheck blood pressure within 2-4 weeks and tell your prescriber so any ramipril dose adjustment can be made.
