Is Magnesium Effective for Migraine?

Magnesium is a natural mineral required by the body to function properly. It plays a role in improving brain health, stabilizing blood pressure, and helping maintain a healthy heart rhythm and nerve function.

It needs to be combined with other substances for this purpose, which is why supplements often have magnesium combined with other substances such as amino acids.
