BulkSupplements.com Magnesium D-Aspartate: 49 mg of magnesium per 680 mg, 1,471 servings
49 mg of magnesium in each 680 mg, about 1,471 servings per 1 Kilogram. Aspartate is 7.5–15.6% magnesium. Inside: salt per scoop, %DV check.
BulkSupplements.com Magnesium D-Aspartate was observed at $35.97 on 2026-09-11; a cost per 100 mg of elemental magnesium is not computed for it because pack weight differs: the offer lists 250 g, the label 1000 g. The observation stays visible and enters no ranking. NIH DSLD 310740, label dated 2024-03-22.

Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
Compound: The whole salt, such as magnesium glycinate, that must physically fit in the capsule.
Size 000: The largest standard capsule, about 1,100 mg of powder at 0.8 g/mL, the top of the usual 0.6–0.8 range; size 00 holds about 730 mg and size 0 about 545 mg.

How much aspartate powder is in one scoop?
BulkSupplements.com Magnesium D-Aspartate carries 313–654 mg of magnesium aspartate per serving for 49 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this powder.

How much elemental magnesium is actually in this label's filed magnesium lines?
BulkSupplements.com Magnesium D-Aspartate files 1 magnesium line in NIH DSLD 310740; the selected primary line declares 49 mg of elemental magnesium per serving, against 0 other rows excluded from the primary amount. A salt named under another nutrient does not turn that nutrient's quantity into elemental magnesium.

Does this label's aspartate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, aspartate, resolved from the full NIH DSLD record text; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.
