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?
Trace Minerals Magnesium Tablets 300 mg files 1 magnesium line in NIH DSLD 322518; the selected primary line declares 300 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?
No single magnesium salt is resolved from the filed record as of 2026-11-02, so the source of the declared magnesium cannot be checked against capsule capacity, compared with oxide, the salt richest in magnesium at 60.3%.

It fuels digestive enzymes and helps the body effectively utilize carbohydrates, proteins, and fats. However, research has shown that many American diets are deficient in magnesium. Magnesium Tablets is a carefully formulated blend of complementary sources of magnesium that help maintain healthy levels of magnesium in your body for optimum health and wellness. We also added Ionic Trace Minerals for healthy body mineral balance. |
