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.
