What Is Potassium?

 Potassium is a mineral and an electrolyte that is important for good health. It plays several key roles in the body, including:

• Heart health: Potassium helps regulate heart rhythm and blood pressure.
• Muscle function: Potassium helps muscles contract and relax properly.
• Fluid balance: Potassium helps regulate the balance of fluids in and around cells.
• Nerve function: Potassium is involved in the transmission of nerve impulses.
• Acid-base balance: Potassium helps regulate the balance of acids and bases in the body.
• Bone health: Potassium helps maintain strong bones by supporting the metabolism of calcium.

Most people can get enough potassium from their diets by eating a variety of foods, including bananas, oranges, potatoes, spinach, and tomatoes. Some people, however, may need to take potassium supplements to meet their needs, especially if they have certain health conditions or are taking certain medications. If you are considering taking a potassium supplement, it's a good idea to talk to your doctor first to determine if it is right for you and to determine the appropriate dosage.
