Magnesium

Magnesium supplements compared against the EU Nutrient Reference Value of 375 mg of elemental magnesium a day. Magnesium is sold as a compound, and pack strengths almost always quote the compound weight rather than the mineral it contains — the elemental fraction ranges from about 60% for magnesium oxide down to roughly 7% for magnesium L-threonate, so a 2,100 mg pack can deliver less magnesium than a 500 mg one.

One caveat this comparison cannot resolve: ranking on dose alone favours magnesium oxide, which is high in elemental magnesium but the least well absorbed of the common forms. Several products here reach 100% of the reference value using oxide or hydroxide, and some blends marketed on their glycinate content are quietly buffered with oxide. Where a label discloses the split we record it; most do not.

Not medical advice

This compares label amounts against published reference doses. It is information, not advice, and it is not personalised. Consult a healthcare professional before starting, stopping or combining supplements — particularly if you take prescription medication.
