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.

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.

Really Liking It!
I decided to try this product for persistent leg cramps that I would get, usually at night while sleeping or during intensive activity. I’ve used other magnesium supplements in the past but frequently had to stop due to stomach upset. The extend-release formula in this one seemed like a good solution.I’ve been taking it for about a week, and I’m very pleased with the results. I’ve noticed a significant reduction in cramps. I was also pleasantly surprised by a couple of other positive effects: I seem to be sleeping more soundly through the night, and I’ve felt noticeably calmer and more focused during my workday.A key factor for me is that I’ve had zero digestive issues with this product. The extend-release design works as advertised. Overall, this has been a very effective supplement and I plan on continuing to use it. I would recommend it.

I am giving four stars, instead of five, for the following easily-fixable reasons:a) On the payments page, I was not able to delete the details of my previous payment cards. And though the current card remained clicked on as the one in use, I was not able to confirm it, and sure enough, I got an email saying that my payment had not gone through. But I was was given the option to ‘Update’ and all is now fine, hopefully. So, may be look into why that glitch happened and something can be smoothed out on that page.b) I would have preferred an SMS on the day of arrival, because with no indication of the time of delivery, I was left unable to plan my day for several days until all my parcels arrived. If I had no work-hours flexibility, this would have been more problematic for me.I am grateful, though, that Amazon was able to group together five of the seven items that I had ordered, into one delivery date. I received my sixth item today, with just one more item expected.So, with thanks for your efficiency, I leave you four stars ⭐⭐⭐⭐.
