Which magnesium? What was actually said on the shows

"Magnesium" is not one decision. The forms behave differently enough that guests on these shows recommend them for different problems, and the distinction is usually the thing a listener half-remembers and gets wrong.

What follows is only what was said on air. Where a guest named a compound rather than a brand — which is almost always — the Amazon listing beneath it is Listener Finds' own pick, and the entry says so.

Not medical advice, and nothing here has been tested by us.
