Magnesium and potassium are both necessary in order to maintain healthy blood pressure already within normal range. But most of us don’t get enough magnesium in our diets. The same goes for potassium. So, we’ve combined our immediate and extended release magnesium with a healthy dose of potassium. This dual-action supplement provides potent blood pressure support.

Benefits at a Glance

  • Supports healthy blood pressure already within normal range1-6
  • Magnesium promotes healthy blood flow by relaxing the smooth muscles in your blood vessels7
  • Potassium promotes cardiovascular health by supporting healthy vasodilation and encouraging the body to expel sodium4
  • Combining these two ingredients offers powerful blood pressure support

More facts about Potassium with Extend-Release Magnesium

Blood pressure is a major health concern for many Americans. Magnesium and potassium are essential to support healthy blood pressure. However, intake of these 2 minerals from your usual diet is often insufficient.8 So we’ve created a magnesium/potassium supplement that promotes cardiovascular health, helps with blood pressure regulation and can be taken with or without other Life Extension blood pressure support supplements.

Magnesium for fast and extended absorption

Your body uses magnesium for a wide range of essential biological reactions.9 It promotes heart, arterial,1-3,10 bone,11,12 muscle health, and more.13-15 Magnesium helps maintain blood pressure levels already within normal range by relaxing the smooth muscles in your blood vessels, supporting blood vessel function, and promoting a healthy inflammatory response.7,16,17

Magnesium also helps transport potassium and calcium across cell membranes, which promotes healthy heart rhythms and supports cardiovascular health.18 Potassium with Extend-Release Magnesium is made with both magnesium oxide and magnesium citrate. It is optimized for both immediate and prolonged uptake to ensure you get the maximum health benefits.

Potassium, magnesium’s sister mineral

Potassium is involved in many of the same biological reactions as magnesium. It supports vasodilation, or the expanding of your blood vessels.4,19 This in turn encourages healthy blood flow.5,19 Potassium also encourages the body to expel sodium through urine, which supports cardiovascular health.

In a randomized, double-blind, placebo-controlled study, daily potassium intake significantly affected systolic blood pressure when compared to the placebo in a four week period.6 Potassium is also important for the transport of electrical signals in the heart to support a steady heartbeat.20

Magnesium-potassium supplementation and blood pressure

These two major mineral nutrients work together to encourage cardiovascular health and provide healthy blood pressure support. In a clinical trial, daily supplementation with both potassium and magnesium affected systolic and diastolic blood pressure readings within four weeks.21
