Why we love it
  • Supports healthy blood flow.
  • Promotes heart rhythm stability.
  • Convenient dual-action mineral formula.
Main Highlights
  • 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.
