Identify the full ingredient name
The supplier describes Aquamin Mg AG as a mineral derived from seawater, with Arabic gum added for processing properties. Its listed specification includes at least 33 % magnesium, solubility in weak acids and insolubility in water. These are ingredient specifications, not a ready-to-take retail dose. [1]
Marine origin does not define the final dose
The mass of the ingredient includes more than elemental magnesium. ODS explains that a supplement’s magnesium amount refers to elemental magnesium, not the whole compound. A supplier specification is useful for understanding a formulation but does not replace the finished product’s Supplement Facts. [2][1]
Do not transfer claims across grades
Imagine a formulation contains 300 mg of an ingredient at a hypothetical 33 % elemental concentration. That would supply 99 mg magnesium, not 300 mg. The calculation illustrates why ingredient weight matters; it is not a recommended dose or a substitute for the manufacturer’s actual finished-product specification. [2]
