Magnesium Intake Recommendations

In 1993, the European Scientific Committee for Food determined an acceptable magnesium intake range for adults of 150–500 milligram (mg) per day (52).

Based on the results of balance studies the U.S. Food and Nutrition Board established a recommended dietary allowance (RDA) for magnesium in 1997 (4):

 Life Stage   Age  Males: (mg/day) Females: (mg/day)
 Infants 0–6 months 30 (AI) 30 (AI)
 Infants  7–12 months 75 (AI) 75 (AI)
 Children   1–3 years 80 80
 Children  4–8 years 130 130
 Children 9–13 years 240 240
 Adolescents 14–18 years 410 360
 Adults 19 - 50 years 400 310
 Adults 51 years and older 420 320
 Pregnancy 18 years and younger - 400
 Pregnancy 19-30 years - 350
 Pregnancy 31 years and older - 360
 Breast-feeding 18 years and younger - 360
 Breast-feeding 19-30 years - 310
 Breast-feeding 31 years and older - 320

In 2010 it has been reported that around 60% of adults in the US do not consume the estimated average requirement for magnesium (60).
