Read the labels! This is especially important if your blood pressure is 120/80 mm Hg or greater. Look for warnings about high blood pressure. And if you have high blood pressure (and certainly if you’re taking prescription medication for it) talk to your healthcare professional before taking any over-the-counter medications or supplements.
Don't fall for “magic pill” claims. There are no special pills, vitamins or drinks that can substitute for prescriptions and lifestyle modifications. Talk to your healthcare provider before taking any OTC drug or supplement that claims to lower your blood pressure. They may not work as advertised, and they could interfere with other medications
