BioCare Magnesium Taurate: 146 mg of magnesium per capsule, 2 capsules a day
146 mg of magnesium per capsule; the label's 2 capsules a day give 292 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
BioCare Magnesium Taurate declares 146 mg of elemental magnesium per serving as taurate, which needs 1,637 mg of magnesium taurate in each capsule, 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: it fits only that size. No US retail price matched as of 2026-11-02; 2 of the 4 taurate labels in this registry have a matched price. NIH DSLD 309746, label dated 2024-06-20.

Mass: 1,637 mg per capsule · Price: none matched · % DV: 39% vs 35%
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 146 mg of taurate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: BioCare Magnesium Taurate implies 1,637 mg of magnesium taurate in each capsule to deliver 146 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 000, read at the most favourable hydration and the most units per serving. The label's 60 capsules over 30 servings imply 2 per serving, so that number is used.

How much elemental magnesium is actually in this label's filed magnesium lines?
BioCare Magnesium Taurate files 1 magnesium line in NIH DSLD 309746; the selected primary line declares 146 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 taurate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, taurate, resolved from the full NIH DSLD record text; 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 "39% Daily Value" mean here, and does it recompute?
The label declares 39% Daily Value; 146 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 35%, a difference of 4 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
