## Overview

Life Extension Potassium with Extend-Release Magnesium combines 99 mg of potassium chloride with a dual-action magnesium blend (oxide and citrate) in a non-GMO, gluten-free vegetarian formula designed to support healthy blood pressure, vascular function, and heart rhythm. Backed by over four decades of scientific research, this supplement promotes optimal blood flow, muscle relaxation, and overall cardiovascular wellness.

## Description

Potassium with Extend-Release Magnesium offers the benefits of a magnesium supplement and a potassium supplement in one all-star heart health formula. Utilizing the oxide and citrate forms of magnesium alongside potassium chloride, these supplements work together for powerful blood pressure support. Potassium helps support healthy blood vessel expansion in the body—essential for promoting optimal blood flow. Magnesium on the other hand helps maintain vascular function by relaxing the blood vessels after they expand. This mineral also promotes quick absorption in the body while absorbing over time for optimal heart health benefits.

Review: Life Extension/Potassium with Extend-Release Magnesium - I felt like I needed more magnesium, so I decided to try this brand. As a senior, I really appreciate the slow extended-release formula-it's made a noticeable difference in my sleep. I am able to relax, feel calmer, and drift off more easily to sleep. Magnesium has also been helpful for leg cramps, which is another big plus. Overall, this has been a great product and I highly recommend it.
Review: Works well. - I am very happy with this mix of Pot and Mag. Saves money, good quality. I take them at night, with my K2D3, as that supplement needs magnesium, so they say. Added benefits: less cramping and better sleep. I like the quality of Life Extension.

## Features

- Potassium for healthy blood flow—Potassium wears many hats, especially when it comes to cardiovascular health. It supports healthy blood vessel expansion, a process known as vasodilation. This encourages healthy blood flow so that the heart can pump blood efficiently. This in turn provides blood pressure support. This formula provides 99 mg of potassium chloride.
- Magnesium for all-around heart health—Magnesium supports many functions within the body, including bone health, but it’s particularly famous for heart health—specifically healthy vascular function. Magnesium relaxes the smooth muscles in the blood vessels, a key component of blood pressure support. It even promotes healthy heart rhythms and arterial health. This formula includes two types of magnesium, magnesium oxide and magnesium citrate, for quick-acting and extended-release benefits.
- Special dual-action mineral formula—Magnesium and potassium have been called “sister minerals” because they are involved in many of the same biological reactions. While it is beneficial to take them as standalone mineral supplements, taking them together is more convenient.
- Ingredients matter—Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.
- Live your healthiest life—For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.
