Magnesium is one of those nutrients most people don’t think about—until they start feeling the effects of low levels: poor sleep, muscle cramps, headaches, fatigue, or anxiety. If you’ve ever searched which type of magnesium is best, you’ve probably noticed there isn’t just one answer. That’s because different forms of magnesium serve different purposes.
In this guide, we’ll break down the most effective types of magnesium, what they’re best for, and how to choose the right one for your specific goal—whether that’s better sleep, migraine relief, or overall wellness.
