Besides the restriction of sodium, there are some nutrients that may help lower blood pressure. For example, one meta-analysis found that supplementation of potassium lowered blood pressure by about 4–5 mmHg.[1] Beetroot juice may also lower blood pressure,[2] which may be partially driven by nitrate content,[3] but also by mechanisms independent of nitrate. Garlic also probably lowers blood pressure in people with hypertension. The form doesn't seem to matter much for lowering systolic blood pressure, but garlic powder may outperform aged garlic extract when it comes to lowering diastolic pressure.[4]
