Why Magnesium Matters for Athletes

Magnesium plays a major role in recovery, sleep, muscle function, and stress management. If you train hard, lift heavy, or simply want to improve your recovery, it’s one of the most important minerals you can supplement.

But with hundreds of magnesium powders on Amazon, it’s easy to get lost in flashy labels and generic blends. That’s why we did the digging and narrowed it down to three magnesium powders that actually work. Whether your goal is deeper sleep, faster recovery, or better focus, these are high-quality, trusted options worth adding to your stack.
