Life Extension Potassium & Magnesium Heart Health Supplement 60 Capsules
Key item 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 – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
- 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.

About this item
Product details
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.

considering that I bought this from Walmart, which is supposed to be a discount store, it was pretty expensive. I think I'll go back to prescribed potassium... I can get that for free.

I recommend this product
Oh my... this potassium with Extended Release Magnesiun works. I take it at bedtime and the cramping in my feet and legs are so much better. I am 72 years old and will continue to take. No after effects at all. Also, I have the best relaxing sleep.

I put I'd recommend but to be honest, it is way to early to say these capsules are doing any good at all. Been taking over a week and am still getting leg cramps at night.
