Daylight pulls back a minute or two each evening and the jacket comes out of the closet before October is over.

Weeks into a magnesium routine, nothing has visibly changed. Sleep has not quickened, soreness after training fades on its own schedule, and the calm that should have settled over evenings never quite showed. The bottle on the nightstand has outlasted two phone chargers. Whatever magnesium was supposed to do, the body has not confirmed it. Most explanations for that silence point at the wrong variable — the form, the dose, the timing. Hardly any of them ask whether the mineral had a deficit to correct at all.
