Magnesium never comes on its own. It’s always bound to something else, and that compound weighs far more than the magnesium inside it. So a magnesium label can show two very different numbers. Only one of them counts.
What other brands might tell youIllustrative example
1,000 mgmagnesium bisglycinate
The compound: magnesium bound to glycine. The bigger number.
140 mgmagnesium · 37% NRV
Elemental magnesium: the magnesium itself, and the number that counts toward the 375 mg NRV.
Some labels lead with the compound weight in large type. It can make a product look like it has several times more magnesium than it does.
