How to read this table
How do you read Magnesium citrate label notation?
Magnesium citrate is about 16% magnesium by molecular weight. A label reading "magnesium 100mg" therefore means several times that weight of raw material went in, and the price per mg on this page uses elemental magnesium, not the raw weight, as its denominator.
How much does Magnesium citrate pricing vary between products?
Products classified as Magnesium citrate number 514, which is 14% of all 3,548 Magnesium products. Classification is by the label's form notation string; products without notation are placed in no form.
