Micronutrient Monday: What Potassium Does & Top Food Sources

Welcome back to Micronutrient Monday, your weekly nutrition deep-dive with Calorie Counter by NutriSnap! Today, we’re spotlighting potassium — a vital mineral that most people don’t get enough of.

Potassium does more than just balance electrolytes. It supports your heart, muscles, and nervous system. Yet studies show that over 90% of Americans fall short of the recommended daily intake.

Let’s explore what potassium does, where to find it in food, and how NutriSnap makes it easy to track.

💓 What Does Potassium Do in the Body?

1. Regulates Fluid Balance

Potassium helps maintain the balance of fluids inside and outside your cells — critical for hydration and cellular function.

2. Supports Healthy Blood Pressure

It counters the effects of sodium and helps relax blood vessel walls, lowering blood pressure naturally.

3. Enables Muscle Contraction

Potassium plays a direct role in smooth and skeletal muscle function — including your heartbeat.

4. Aids Nerve Signaling

Proper potassium levels are essential for efficient nerve communication throughout your body.


🚨 Signs You Might Be Low in Potassium

  • Muscle cramps or weakness
  • Irregular heartbeat or palpitations
  • Constipation or bloating
  • Tingling or numbness
  • Chronic fatigue or brain fog

Low potassium can result from poor diet, dehydration, excessive sweating, or certain medications (like diuretics).
