Magnesium appears on many labels — but behind it hide very different compounds. Magnesium never goes into a capsule in elemental form, but always bound: to an acid, an amino acid or as a salt. Which bond it is determines solubility, tolerability and how much elemental magnesium is actually contained.
The seven forms at a glance
Magnesium citrate — bound to citric acid, the organic form with high solubility.
Magnesium bisglycinate — bound to the amino acid glycine, the gentle, stomach-friendly form.
Magnesium gluconate — bound to gluconic acid, a highly soluble organic form.
Magnesium glycerophosphate — bound to glycerophosphate, the fat-soluble organic component.
Magnesium oxide — the compact depot form: a lot of elemental magnesium in little space.
Magnesium carbonate — the alkaline form, rounding off the spectrum.
Magnesium chloride — the salt-like, very readily water-soluble form.
Why the combination?
Each compound brings different properties. A mix of organic and inorganic forms combines fast solubility with a compact magnesium content — NUI Magnesium 7 contains 500 mg of elemental magnesium per daily serving (133 % NRV) from seven sources.
How to take it: it doesn’t get simpler
Two capsules daily with a meal, with a large glass of water. Many tie the intake to their evening routine — regularity matters more than the time of day.
