Why Runners Are Obsessed with Magnesium (And Should You Be Too?)

If you’ve ever cramped up mid-run, struggled to recover, or just felt drained for no clear reason—magnesium might be the missing piece.

Runners lose a lot of this essential mineral through sweat, and most people don’t get enough of it in their diet to begin with. That’s a recipe for fatigue, soreness, and frustrating plateaus.

Why Magnesium Matters for Runners

Magnesium plays a role in over 300 biochemical reactions in the body. For runners, it’s especially important because it:

• Helps muscles contract and relax

• Supports energy production

• Reduces inflammation and oxidative stress

• Aids recovery and sleep quality

Without enough magnesium, your muscles are more prone to cramping, fatigue sets in quicker, and recovery slows down.

How to Tell If You’re Low

Common signs of deficiency include:

• Muscle cramps or twitches

• Trouble sleeping

• Persistent fatigue

• Increased irritability or anxiety

How to Get More

You can get magnesium from whole foods like spinach, almonds, pumpkin seeds, and dark chocolate—but when you're training hard, food alone often isn’t enough.

Many athletes supplement with:

• Oral magnesium (citrate or glycinate are well-absorbed)

• Magnesium baths or sprays for local relief

• Recovery drinks with added electrolytes

That’s why we’ve made magnesium a key ingredient in our EverRun Recovery Mix—to help you bounce back stronger and run fresher the next day.
