Life Extension Potassium with Extend-Release Magnesium – Heart health supplement for blood pressure support with two essential minerals – Non-GMO, vegetarian, gluten-free – 60 capsules
4,913 Reviews
Life Extension Potassium with Extend-Release Magnesium – Heart health supplement for blood pressure support with two essential minerals – Non-GMO, vegetarian, gluten-free – 60 capsules
  • 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.

Best 10 Benefits of Potassium

Potassium is the seventh most abundant element and the third most abundant mineral in the human body. It serves several purposes, including breaking down carbohydrates, preventing strokes, and promoting renal and cardiovascular health. Bananas, milk, poultry, and potatoes are all rich sources of potassium. Below are ten great benefits of potassium.

1. Stabilizes blood sugar

A potassium deficiency may cause low blood sugar. This can worsen a diabetic’s condition and even cause problems in non-diabetics, such as a headache, sweating, trembling, or weakness.

2. Prevents kidney stones

Potassium aids the kidneys in excreting waste, and when excretion is regular, it prevents the buildup of hardened waste within the kidneys, thereby reducing the risk of developing a kidney stone.

3. Alleviates stress

This element regulates hormones such as adrenaline and cortisol that are known to increase stress levels. A healthy amount of potassium reduces these hormones, resulting in a less stressful environment.

4. Stimulates the brain

Potassium aids in transporting oxygen to the brain, thereby improving cognitive function and neural activity as well as preventing cognitive decline.

5. Promotes cardiovascular health

It is important to take in a healthy level of potassium, as an insufficient amount increases the risk of cardiovascular diseases and conditions such as heart attack or stroke. One direct benefit of potassium is promoting an even, regular heartbeat.

6. Improves bone health

Potassium regulates several nucleic acids within the body that are responsible for retaining and using calcium, which is vital in promoting strong bones. High levels of potassium increase bone density, thus preventing fractures and warding off conditions such as osteoporosis.

7. Boosts metabolism

This mineral plays an essential role in absorbing and utilizing nutrients we consume, thereby speeding up metabolism. Potassium also regulates the synthesis of protein from amino acids.

8. Strengthens muscles

Regular potassium intake is especially important for athletes and trainers. It helps build muscle while preventing cramps and even aids in staving off atrophy during periods of extended rest.

9. Normalizes blood pressure

Along with sodium, potassium is responsible for maintaining a healthy blood pressure. Its vasodilatory properties reduce tension on the walls of blood vessels, thus allowing the blood to flow more freely and at a lower pressure point.

10. Maintains fluids

Bodily fluids are primarily composed of water and electrolytes. Potassium is needed to not only maintain these properties, but also ensure that fluids levels stay in a healthy range. This is especially important when performing strenuous exercise, which is why many athletes eat bananas before or after performances.
