Potassium is a dietary mineral required in relatively large quantities in comparison with other minerals found in the human diet. It is the most abundant positively charged ion, or cation, in the cytosol, the liquid cytoplasmic matrix found inside all cells of the human body. It has a special relationship with sodium, the major cation outside animal cells. Together they facilitate cellular reformations and intercellular activities, greatly influencing the development of muscles, the brain, and the heart.

Electrolytes are solutions of bases or acids that help maintain a healthy pH inside the body. Potassium is an electrolyte absolutely necessary for the upkeep of cells. They enable organic compounds to move charges, which is central to neuronal activities, muscle contraction, and endocrine functions. The presence of potassium is also required to activate the catalytic functions of several enzymes. Some of these enzymes are indispensable in the metabolism of carbohydrates.

Powers Cellular Activities

A cellular phenomenon described as membrane potential affects several types of cells throughout the human body, such as neurons, muscle cells, and endocrine cells. Potassium is involved in this phenomenon, powering countless molecular devices found in the cell membrane much like a battery. It also participates in transmitting signals between cellular organelles, creating an electric current that flows between different parts of the cell.

Intercellular communication that induces the release of neurotransmitters, hormones, and other related organic compounds throughout the body rely on healthy levels of potassium. For example, it allows the beta cells of the pancreas to respond to levels of carbohydrates that get in and out of the systemic circulation, releasing insulin when needed. It fuels a chain of cellular events that lead to many bodily functions.

Promotes Muscle Function

It is not a coincidence that unhealthy levels of potassium lead to bouts of muscle cramps. While involuntary contractions of the skeletal muscles are often associated to older populations, they may afflict people of all ages at any time of the day. More often than not, the underlying cause is malnutrition, especially deficiency in dietary minerals like potassium.

Contractions produced by skeletal muscles are a classic example of physiological functions that necessitate the presence of potassium. When electrical impulses of cell membranes rise and fall at a very fast rate, it results in a cellular event called action potential, igniting a chain of events that lead to muscle contraction. This is the reason why potassium is important in the maintenance of healthy muscles.

Maintains Cardiovascular Health

Potassium is particularly good for the heart. The cardiac muscle is engaged in continuous coordinated contractions that propel blood out of the atria and ventricles to the rest of the cardiovascular system. A condition called hypokalemia, in which the level of potassium in the blood is low, has been linked to abnormal heart rhythms, high blood pressure, and congestive heart failure. Not surprisingly, potassium supplements are used as a therapeutic remedy in the treatment of these diseases.

pH Balance

Potassium has a pH of 14. Taking potassium daily can help you regulate your pH so you can maintain a pH of 7 throughout the day. By maintaining a pH of 7, you can improve your health and reduce the instance of illness.
