Viva Vitamins Super Magnesium 375 mg: 375 mg of magnesium per tablet, 1–2 tablets a day – amino acid chelate + ascorbate + aspartate + citrate + oxide
375 mg of magnesium per tablet; the label's 1–2 tablets a day give 375–750 mg. Inside: label lines, ingredients.
Viva Vitamins Super Magnesium 375 mg declares 375 mg of elemental magnesium from an amino acid chelate. "Amino acid chelate" names a class of compounds rather than one defined substance, so no elemental fraction exists and the compound mass cannot be computed from the label. No US retail price matched as of 2026-11-02. NIH DSLD 239004, label dated 2020-11-21.

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 elemental magnesium is actually in this label's filed magnesium lines?
Viva Vitamins Super Magnesium 375 mg files 1 magnesium line in NIH DSLD 239004; the selected primary line declares 375 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 magnesium claim hold up, or could the magnesium come from another source?
The label names 5 magnesium forms (amino-acid-chelate, ascorbate, aspartate, citrate, oxide); a named blend does not establish how much magnesium each form contributes, so the resolved reading is the most favourable one, compared with oxide, the salt richest in magnesium at 60.3%.

|---|---|---|
| amino-acid-chelate | No defined fraction | named on label |
| ascorbate | No defined fraction | named on label |
| Magnesium aspartate | 7.5–15.6% | named on label |
| Magnesium citrate | 11.3–16.2% | named on label |

Is this a good price for the elemental magnesium I'm actually getting?
No US retail price is matched to this label as of 2026-11-02, and without a resolved salt there is no same-salt comparison.

What does "94% Daily Value" mean here, and does it recompute?
The label declares 94% Daily Value; 375 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 89%, a difference of 5 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.

| Formula re: Contains | Magnesium plays important roles in the structure and the function of the human body. The adult human body contains about 25 grams of magnesium. Over 60% of all the magnesium in the body is found in the skeleton, about 27% is found in muscle, 6% to 7% is found in other cells. In addition, magnesium is involved in more than 300 essential metabolic reactions including energy production, protein and nucleic acid (RNA, DNA) synthesis, and the transport of calcium and potassium across cell membranes. |
