If you’ve been feeling foggy, drained, moody, or stuck in a cycle of weight changes that don’t make sense, your thyroid might be at the center of it.

That small, butterfly-shaped gland at the base of your neck regulates metabolism, energy, and mood—and when it’s out of sync, everything else can feel off too.

Let’s take a closer look at how your thyroid works, the red flags to watch for, and the supplements that can help bring things back into balance.
