Magnesium supplement dosage
By admin on July 25th, 2009Recommendations for magnesium are provided in the Dietary Reference Intakes (DRIs) developed by the Institute of Medicine of the National Academy of Sciences. Dietary Reference Intakes is the general term for a set of reference values used for planning and assessing nutrient intake for healthy people. Three important types of reference values included in the DRIs are:
- Recommended Dietary Allowances (RDA), average daily intake that is sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people.
- Adequate Intakes (AI), AI is set when there is insufficient scientific data available to establish a RDA for specific age/gender groups. AIs meet or exceed the amount needed to maintain a nutritional state of adequacy in nearly all members of a specific age and gender group.
- Tolerable Upper Intake Levels (UL), the maximum daily intake unlikely to result in adverse health effects.
Recommended Dietary Allowances for magnesium for children and adults
| Age (years) |
Male (mg/day) |
Female (mg/day) |
Pregnancy (mg/day) |
Lactation (mg/day) |
|---|---|---|---|---|
| 1-3 | 80 | 80 | N/A | N/A |
| 4-8 | 130 | 130 | N/A | N/A |
| 9-13 | 240 | 240 | N/A | N/A |
| 14-18 | 410 | 360 | 400 | 360 |
| 19-30 | 400 | 310 | 350 | 310 |
| 31+ | 420 | 320 | 360 | 320 |
There is insufficient information on magnesium to establish a RDA for infants. For infants 0 to 12 months, the DRI is in the form of an Adequate Intake (AI), which is the mean intake of magnesium in healthy, breastfed infants. Table 3 lists the AIs for infants in milligrams (mg).
Recommended Adequate Intake for magnesium for infants
| Age (months) |
Males and Females (mg/day) |
|---|---|
| 0 to 6 | 30 |
| 7 to 12 | 75 |
