The card contains no comparison with other forms of magnesium and no list of groups for whom the supplement suits best. It gives the dosage for adults: 2 tablets a day, taken with water (200 mg of magnesium, 48 % NRV). Do not use in case of hypersensitivity to the ingredients; during pregnancy and breastfeeding consult a doctor; do not use as a substitute for a varied diet.
General information (not a manufacturer's instruction): whether this particular form of magnesium suits you depends on how you feel, your diet and the medicines you take; this is better discussed with a doctor or pharmacist.
