Low Potassium – Symptoms, Signs, Diet, Causes, and Treatment

Potassium is a critical mineral that supports nerve function, muscle strength, fluid balance, and heart rhythm, making it essential for overall health and physical resilience—especially in stressful or emergency situations. Many people don’t get enough due to poor diet, and low levels can lead to weakness, cramps, high blood pressure, and even heart issues. Because blood tests don’t always show deficiency, it’s important to maintain potassium through whole foods like avocados, bananas, and vegetables rather than relying on supplements. In a preparedness mindset, keeping electrolytes balanced is key to staying functional when it matters most.
