The RDA for magnesium is 310–420 mg for adults depending on age and gender. If you require a supplement, dosage recommendations can vary depending on your needs, such as to improve constipation, sleep, muscle cramps, or depression. Most studies found positive effects with daily doses of 125–2,500 mg.

Many types of fish are high in magnesium, including salmon, mackerel and halibut. Half a fillet (178 grams) of salmon packs 53 mg of magnesium, which is 13% of the RDI (35). It also provides an impressive 39 grams of high-quality protein.

(a) Magnesium has atomic number 12, so all atoms of magnesium contain 12 protons and 12 electrons. The three isotopes are therefore represented by Mg, Mg, and Mg. (b) The number of neutrons in each isotope is the mass number minus the number of protons.
