Hypertension (High Blood Pressure)

One out of three U.S. adults has high blood pressure, also called hypertension. Over time, this condition can damage the heart, blood vessels, kidneys, and other parts of the body. High blood pressure is managed with lifestyle changes and, if necessary, medication.

People sometimes wonder whether specific foods or dietary supplements could help control high blood pressure. Research results suggest that some, such as cocoa, garlic, fish oil, flaxseed, green or black tea, probiotics, and the herb roselle, might have an effect. However, the evidence that these products can lower blood pressure is limited, and the effects of the products on blood pressure are small. No dietary supplement has been shown to have effects comparable to those of the medicines used to treat hypertension.

If you have high blood pressure, follow the treatment plan prescribed by your health care provider. Following your treatment plan is important because it can prevent or delay serious complications of high blood pressure. Don’t replace your prescribed treatment with an unproven product or practice. If you’re considering trying a dietary supplement or other complementary approach for your high blood pressure, discuss it with your health care provider.
