Your blood pressure is something you might overlook until an emergency arises, such as a heart attack or stroke. Yet, high blood pressure (or hypertension) is prevalent, especially among men, with about 50% of adult men in the U.S. affected, according to the CDC. Therefore, it’s crucial to manage it proactively.
Consider reducing salt intake and monitoring alcohol consumption. Another beneficial habit is ensuring sufficient magnesium intake, potentially through supplements, as increasing magnesium can support heart health directly.
### How Magnesium Supports Blood Pressure
While omega-3s, fiber, and potassium usually dominate discussions about heart health, magnesium plays a significant role as well. Dr. Menka Gupta, a functional medicine physician, explains that magnesium helps control blood vessel muscles. Low magnesium levels lead to increased production of substances that constrict blood vessels and cause fluid retention, raising blood pressure.
Registered dietitian Dr. Cheryl Marsland notes that magnesium supports the endothelium, or inner lining of blood vessels, and aids in producing nitric oxide, allowing vessels to relax and dilate properly. Additionally, low magnesium can spike stress and anxiety, which are linked to elevated blood pressure.
A 2024 review highlights that magnesium depletion is linked to hypertension. Dr. Andrea Colon, a naturopathic physician, adds that low magnesium can lead to calcium buildup in blood vessels, causing them to tighten and raise blood pressure. Think of magnesium as vital for maintaining steady blood flow, preventing excessive pressure buildup.
### Increasing Magnesium to Lower Blood Pressure
Most people can benefit from increasing their magnesium intake, even if they’re not deficient. Dr. Colon often recommends magnesium supplements for managing high blood pressure, as it helps relax blood vessel walls, improving blood flow and potentially lowering pressure.
While the effects might not be drastic, experts agree that increasing magnesium intake can be a valuable component of a broader strategy for heart health. Remember, magnesium is just one piece of the cardiovascular puzzle—it’s not a standalone solution.
