Why Should I Maintain Adequate Potassium Levels?

Maintains The Nervous System

Potassium is an essential electrolyte that helps maintain the functioning of the nervous system. The nervous system of our body relays messages between the brain and body. 

Sodium and potassium ions carry electrical impulses through the nerves. These signals help to regulate muscle reflexes, muscle contractions, and other neurological functions. 

Neurons generate nerve impulses by entering sodium ions into the cells and exiting the potassium ions from the cells.

Maintains Fluid and Electrolyte Balance

Our body consists of 60% of water. Out of this, 40% is present inside the cells in intracellular fluid (ICF). In contrast, the rest of the water is present in blood outside the cells in the extracellular space known as Extracellular fluids (ECF). 

Electrolytes such as Potassium and sodium regulate the ICF and ECF. Without adequate regulation and balance, the cells will shrink or burst. You should consume proper electrolytes, especially Potassium and other fluids, to maintain organ health.     

Reduce blood pressure: 

Potassium helps eliminate excess sodium from the body. Excess sodium can increase blood pressure. Therefore, the elimination of excess sodium helps keep blood pressure in check. 

Prevents osteoporosis: 

Osteoporosis is a disease of the bones, in which your bones become brittle and susceptible to fractures. In this disease, lack of calcium makes your bones porous. Potassium helps reduce the elimination of excess calcium from the body and thus helps your bones remain strong.

Reduces the risk of stroke: 

Lower blood pressure means a lower risk of heart disease. People who are at risk of heart stroke should increase their potassium intake.

Reduce fluid retention: 

Potassium increases urine production, which helps reduce fluid retention in the body. If you eat more salt, you should also eat more potassium-rich foods.

Prevents kidney stones: 

Potassium helps lower the calcium concentration in the urine. A higher concentration of calcium in the urine can lead to the formation of kidney stones. If you have had kidney stones or are at risk of having them, a potassium-rich diet will help you avoid them.

Controls muscle contraction: 

Potassium helps in the process of muscle contraction in the gut and heart muscles.
