Magnesium is often called a ‘miracle mineral’ for its wide range of benefits, from muscle relaxation to improved sleep quality. But one of its lesser-discussed impacts is its role in regulating blood pressure. With heart health being a top priority for many, understanding how dietary magnesium affects blood pressure is crucial....READ ORIGINAL & FULL CONTENT FROM SOURCE |
Whether through supplements or magnesium-rich, could incorporating this mineral into your diet be a simple yet powerful way to support cardiovascular well-being?
How does magnesium specifically impact blood pressure regulation?
Dr Palleti Siva Karthik Reddy, MBBS, MD, internal medicine consultant at Koshys Hospital, tells indianexpress.com, “Magnesium plays a critical role in regulating blood pressure by influencing several physiological mechanisms. Incorporating magnesium in the diet can help relax and widen blood vessels by regulating calcium and potassium levels in vascular smooth muscles. This process, known as vasodilation, lowers resistance within blood vessels, reducing blood pressure.”.
He adds that it works with potassium and sodium to maintain electrolyte balance. It prevents excessive sodium retention, which is a major contributor to hypertension. Additionally, magnesium inhibits the action of angiotensin II, a hormone that causes blood vessels to constrict. By reducing vascular resistance, magnesium eases the workload on the heart.
Chronic inflammation contributes to hypertension. Magnesium reduces levels of inflammatory markers like C-reactive protein (CRP), which indirectly helps regulate blood pressure. Magnesium reduces the release of stress hormones like cortisol and adrenaline, which can spike blood pressure in stressful situations.
Dr Reddy reveals, “A meta-analysis published in Hypertension showed that increasing magnesium intake by 100 mg per day was associated with a modest reduction in systolic and diastolic blood pressure. This highlights its role as a valuable tool for cardiovascular health.”The recommended daily magnesium intake varies by age and sex: adult men need 400–420 mg/day, and adult women require 310–320 mg/day.
Forms of magnesium that are more effective for managing blood pressure
According to Dr Reddy, not all magnesium supplements are equally effective due to varying bioavailability. Magnesium citrate is highly absorbable and ideal for blood pressure regulation and alleviating constipation. Magnesium glycinate, bound to glycine, is gentle on the stomach and beneficial for anxiety and blood pressure management.
Magnesium oxide has a high magnesium concentration but lower absorption, making it more suitable for digestive issues. Magnesium taurate combines magnesium with taurine, promoting cardiovascular health and reducing blood pressure. Magnesium malate includes malic acid, supporting energy production and muscle relaxation.
