Absorption and effect of the magnesium content of a mineral water in the human body

Objective: The kinetics of magnesium (Mg) absorption, after drinking Magnesia mineral water (204 mg Mg/L), was investigated in healthy humans aged (23–60 yrs).Methods: Serum Mg, calcium (Ca), potassium (K) and sodium (Na) content, blood hemoglobin, erythrocyte and white blood cell counts as well as urinary volume and urine Mg content were evaluated. Subjects drank 1.5 liters of Magnesia in 30 minutes; blood and the other tests were taken at 0, 2, 6, 24 and 48 hours, and after 1, 2, 3 and 4 weeks. Serum ion quotient was calculated. Serum Mg levels increased in all cases, and returned to individual normal values after 48 hrs. Subjects drank copious amounts of the mineral water only on the first two days, later they consumed one glass of mineral water at a time, totalling 1–1.5 liters daily.Results: Urinary volume and its Mg content significantly increased, with individual differences in urine Mg content depending on degrees of tissue Mg deficiency. For example, two subjects, who had the same initial serum M...
