What the rat studies and small human trials of magnesium L-threonate measured, who funded them, and how much elemental magnesium you really get.
What the magnesium and sleep trials really tested, why glycinate labels mislead, safe upper limits (NHMRC, NIH, EFSA), medicine interactions and better sleep first steps.
Why 500 mg of magnesium oxide and 500 mg of glycinate hold very different amounts of magnesium, how to find the elemental figure, and what to check first.
Which everyday foods supply the most magnesium, how much adults need in different countries, a worked day of eating, and why food has no upper limit.
