High blood pressure (hypertension) is a common condition in which the pressure of your blood against your blood vessel walls poses a risk to your health. Over time, high blood pressure can damage your blood vessels and put you at a greater risk for stroke or heart attack.
High blood pressure is a condition that often carries no symptoms and can go undetected for years. More than worldwide live with raised blood pressure.
High blood pressure is diagnosed using two numerical measurements: diastolic and systolic pressure.
Systolic blood pressure is the pressure against your artery walls during a contraction of your heart (a heartbeat). A systolic blood pressure measurement of 120 or above is considered elevated. Above 130 is considered high.
Diastolic is the pressure on your arteries in between heartbeats. A diastolic blood pressure measurement above 80 is considered high.
Doctors use both your systolic and diastolic blood pressure measurements to determine if you have high blood pressure, and if treatment may be necessary.
Many people are interested in using natural supplements to help improve their blood pressure, either along with blood pressure medication or to avoid taking these medications altogether.
You should always check with your doctor before starting any supplement to treat high blood pressure. Supplements alone may not be enough to resolve high blood pressure.

Although many supplements may help slightly lower blood pressure, they haven’t been proven to lower the risk of heart attacks and strokes in people with high blood pressure. Be sure to talk to your doctor about the best treatment options for your specific needs.
When purchasing supplements, remember that they aren’t regulated by the Food and Drug Administration the same way prescription medications are. Only purchase supplements from suppliers that you trust.
