3 Key Signs of a Potassium Deficiency

Why potassium matters more than most people realize

Potassium is one of the body’s main electrolytes. Electrolytes are minerals that carry an electrical charge when dissolved in fluid. That electrical charge helps cells communicate.

Your body uses potassium to support:

• Muscle contraction

• Nerve signaling

• Fluid balance

• Heart rhythm

• Blood pressure regulation

  
  

Low potassium is also called hypokalemia. It can happen for many reasons, including heavy sweating, vomiting, diarrhea, certain medications, low food intake, or medical conditions that affect the kidneys or hormones.

Mild potassium deficiency can be easy to miss. The signs may feel like normal fatigue, soreness, or water retention. But when potassium keeps dropping, symptoms can become more noticeable and potentially serious.

How much potassium do you need?

For healthy U.S. adults, the Adequate Intake is approximately 3,400 mg/day for men and 2,600 mg/day for women. Needs differ during pregnancy and breastfeeding and may need significant modification in people with kidney or certain cardiovascular/endocrine conditions.

If your having difficulties getting enough potassium in your diet consider the following supplement.
