Alternative medicine

Although diet and exercise are the most appropriate tactics to lower your blood pressure, some supplements also may help lower it. However, more research is needed to determine the potential benefits. These supplements include:

• Fiber, such as blond psyllium and wheat bran
• Minerals, such as magnesium, calcium and potassium
• Folic acid
• Supplements or products that increase nitric oxide or widen blood vessels (vasodilators), such as cocoa, coenzyme Q10, L-arginine and garlic
• Omega-3 fatty acids, found in fatty fish, high-dose fish oil supplements and flaxseed

Researchers are also studying whether vitamin D can reduce blood pressure, but evidence is conflicting. More research is needed.

While it's best to include these supplements in your diet as foods, you can also take supplement pills or capsules. Talk to your doctor before adding any of these supplements to your blood pressure treatment. Some supplements can interact with medications, causing harmful side effects, such as an increased bleeding risk that could be life-threatening.

You can also practice relaxation techniques, such as deep breathing or mindfulness, to help you relax and reduce your stress level. These practices may temporarily reduce your blood pressure.
