Divine Bounty Magnesium Citrate: 104 mg of magnesium per capsule, 2 capsules a day, $7.98 a month
104 mg of magnesium per capsule; the label's 2 capsules a day cost $7.98 a month (Amazon, Nov 2). Inside: salt weight, capsule size, price rank.
Divine Bounty Magnesium Citrate declares 208 mg of elemental magnesium per serving as citrate, which needs 644–920 mg of magnesium citrate in each capsule, against 730 mg in a size 00 capsule at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range: it needs size 00 or larger. Observed at $0.1278 per 100 mg, rank 7 of 12 ranked citrate offers (1 = lowest price per 100 mg), percentile 58 (lower = lower price). NIH DSLD 229221, label dated 2020-07-23.

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.

Will 208 mg of citrate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Divine Bounty Magnesium Citrate implies 644–920 mg of magnesium citrate in each capsule to deliver 208 mg of elemental magnesium, against 1,100 mg in the largest standard capsule (size 000) at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range. Verdict: needs size 00, read at the most favourable hydration and the most units per serving.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 208 mg |
| Units per serving | 2 |
| Magnesium citrate per serving | 1,287–1,841 mg |
| Magnesium citrate per capsule | 644–920 mg |
| Capsule capacity 0 · 00 · 000 | 545 · 730 · 1,100 mg |
| Verdict | Needs size 00 |
The filed salt can have more than one hydration state (trimagnesium dicitrate 16.2%; dibasic and hydrated forms as low as 11.3%), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Divine Bounty Magnesium Citrate files 1 magnesium line in NIH DSLD 229221; the selected primary line declares 208 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 citrate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, citrate, resolved from the filed magnesium line; at that salt the declaration is within the assumed size 000 capacity at powder density 0.8 g/mL, compared with oxide, the salt richest in magnesium at 60.3%.

What does "52% Daily Value" mean here, and does it recompute?
The label declares 52% Daily Value; 208 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 50%, a difference of 2 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
