Potassium is an essential nutrient used to maintain fluid and electrolyte balance in the body. It’s also the third most abundant mineral in the body and a required mineral for the function of several organs, including the heart, kidneys, brain and muscular tissues ^[1].

In the human body, potassium is required for the proper function of several vital bodily processes, including nerve signal transmission, muscle contraction, and maintaining a normal blood pressure level ^[2].

Consuming adequate amounts of potassium can provide several health benefits, including reduced blood pressure, improved cardiovascular health, and decreased risk of stroke. Furthermore, potassium may enhance bone health and reduce the risk of kidney stones ^[3].

While potassium from dietary sources is likely safe for most people, potassium supplements can cause stomach upset, nausea, diarrhea, and vomiting in some people. It can also cause feelings of burning or tingling and could lead to serious health problems like hyperkalemia in people with kidney problems or those who take certain medications ^[4].

Potassium can interact with certain medications such as water pills (diuretics), angiotensin converting enzyme (ACE) inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs). These medications can increase the amount of potassium in the body and lead to hyperkalemia, a serious condition that can affect the heart ^[5].

The recommended daily intake of potassium for adults is 4,700 milligrams (mg) ^[6]. However, the average intake is often much lower, especially in Western countries. However, always consult a healthcare provider before starting or changing a supplement regimen.
