I read the magnesium research so you don't have to.

I'm Sara Walker. Somewhere around forty-five I stopped sleeping properly, started waking up with calf cramps, and went looking for answers. What I found was a wall of supplement marketing and a much quieter pile of actual studies.

So I started reading the studies. Glycinate versus citrate versus oxide. What the trials actually measured. Where the evidence is decent and where it's thin. Then I write it down in plain English.
