For you, if you are looking for a formula that can support normal blood pressure

The active formula of Potassium with Extend-Release Magnesium can:
  • Support healthy blood pressure already within the normal range [1-6]
  • Provide magnesium support that promotes healthy blood flow by relaxing the smooth muscles in your blood vessels [7]
  • Provide potassium which promotes cardiovascular health by supporting healthy vasodilation and encourages the body to expel sodium [4]
  • Offer powerful blood pressure support

Magnesium and potassium are both necessary in order to maintain healthy blood pressure already within normal range. However, most of us do not get enough of either these two crucial minerals through our diets. Life Extension® has combined both immediate and extended release magnesium with a healthy dose of potassium, which makes for a potent dual-action formula which provides potent blood pressure support.

Product details "Potassium with Extend-Release Magnesium"
Health benefits at a glance:

Although blood pressure is a major health concern for many people, intake of magnesium and potassium, which support normal blood pressure, is often not achievable through a normal diet [8].  

Potassium with Extend-Release Magnesium from Life Extension® is a novel magnesium/potassium supplement that can promote cardiovascular health and helps with blood pressure regulation.

Why it works:

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.


Your body uses this mineral for about 300 different biological reactions in your body [9]. It promotes heart, arterial [1-3,10] bone [11,12] muscle health, and more [13-15]. It helps to 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].

Moreover, it also helps transport potassium and calcium across cell membranes, which promotes healthy heart rhythms and supports cardiovascular health [18].


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

The science behind the product:

Both of these minerals have been studied intensely.

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].

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 of these minerals affected systolic and diastolic blood pressure readings within four weeks [21].
