Systematic review Jun 7, 2026

Garlic for Cardiovascular Health: A Systematic Evidence Review

Garlic looks useful, but not magical. The best evidence says it can modestly lower regular blood pressure readings and slightly improve LDL and total cholesterol, especially in people who already have elevated risk markers. That means garlic may be worth considering as an add-on if you want a small extra push in the right direction. It does not look strong enough to count on by itself, and it has not been shown here to prevent heart attacks or strokes. If the goal is cardiovascular support, choose garlic with realistic expectations: think modest help with blood pressure and routine labs, not a substitute for proven medical care.
