Potassium

Overview:

Potassium is an essential mineral and electrolyte that plays a key role in maintaining proper cell function, fluid balance, nerve signals, and muscle contractions.

Sources:

Potassium is abundant in fruits and vegetables, particularly bananas, oranges, potatoes, spinach, and avocados. It is also available in supplement form, often as potassium chloride or potassium citrate.

Functions:

Electrolyte Balance: Potassium helps maintain fluid balance and electrolyte levels in the body.

Nerve Function: It is crucial for transmitting nerve signals and proper functioning of the nervous system.

Muscle Contraction: Potassium supports muscle function, preventing cramps and maintaining healthy heart function.

Deficiency:

Potassium deficiency, known as hypokalemia, can cause symptoms such as muscle weakness, cramping, fatigue, and irregular heart rhythms. It can result from inadequate dietary intake, excessive sweating, or certain medications.

Toxicity:

High levels of potassium, known as hyperkalemia, can cause symptoms such as nausea, irregular heartbeat, and muscle weakness. Severe hyperkalemia can be life-threatening, so it is important to manage potassium intake carefully, especially in individuals with kidney problems.
