When we talk about physical health, we usually think about food and movement—but real health goes deeper. It includes how we sleep, how we manage stress, and how our nervous system functions. Today we’re talking about magnesium, a mineral that plays a role in over 300 biochemical reactions in the body—and one many of us are deficient in.

Recently, a study suggested that magnesium may be as effective as antidepressants for some people when it comes to mild to moderate depression. That’s powerful—and it opens the door to seeing mental and physical health as deeply connected.
