MAGNESIUM COMPOUNDS

the share of magnesium in the salt, computed from the formula · and what human trials measured

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

This is not medical advice and not a recommendation. Here are the compositions computed from formulas and what the named trials measured. For whom, how much and what for — ask a doctor.

THE SHARE IN THE SALT AND THE SHARE TAKEN UP ARE TWO DIFFERENT NUMBERS

Magnesium oxide holds more magnesium than any other form on this sheet: 60.30 % of its own mass, and that follows straight from MgO and the atomic weights. On the box it is the largest number on the shelf.

Firoz and Graber (Magnesium Research, 2001) measured the absorption of four preparations by the increment of 24-hour urinary magnesium and put the oxide at 4 %; chloride, lactate and aspartate came out higher than it and equal to one another.

Yet those 4 % are not a property of the oxide either, but the result of one method in one group: Schuette and colleagues (JPEN, 1994) measured the same oxide with a labelled isotope in patients after bowel resection and got 22.8 %. The two numbers answer two different questions, and the box prints neither.

On the sheet

  • This is not medical advice and not a recommendation. Here are the compositions computed from formulas and what the named trials measured. For whom, how much and what for — ask a doctor.
  • Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
  • Nothing about how it was made: the sheet carries only what the reader needs.

Printing

  • Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
  • All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
  • White background and sparing fills — it prints on a home printer without draining the cartridge.
  • Margins of at least 10 mm: a home printer cannot print to the edge.
  • No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 7 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
