A form of magnesium
Magnesium aspartate supplements
1,038 magnesium products in the NIH label database list magnesium as magnesium aspartate (7% of the 15,088 magnesium products); their median is 150 mg of magnesium per serving, against 86 mg across all magnesium products; the 34 whose only supplement ingredient is magnesium list a median of 400 mg (DSLD version 9.4.0, January 2026).
How does magnesium aspartate compare with the other forms?
The median amount of magnesium per serving in products naming each form; the count in brackets. The amount is the magnesium the label gives, as printed (the Supplement Facts row normally states the element; a row named as the compound usually gives the compound's weight and is left out of these figures).

Is the amount the magnesium or the whole magnesium aspartate?
A Supplement Facts row normally states the magnesium itself (a row like "Magnesium (as magnesium aspartate)"); a row named as the compound (a row like "Magnesium aspartate") usually states the compound's weight, which includes what the magnesium is bound to and is larger than the magnesium it supplies. The front of a bottle may print either. Of the 1,038 products here, 941 give the magnesium in its own row (9 of them an amount far outside what other labels list, or one their own %DV disagrees with); 96 give only a row named as the compound, left out of the medians and counts on this site; 1 give no amount of their own or one in another unit.
The adult Tolerable Upper Intake Level for magnesium is 350 mg a day; it covers magnesium from supplements and medicines only, not food or water. At the most servings their labels direct, 306 of the 932 magnesium aspartate products with a plausible amount (32.8%) give more than that.
