Nature's Way Alpha Betic Cinnamon with Magnesium & Biotin: 67 mg of magnesium per capsule, 3 capsules a day

67 mg of magnesium per capsule; the label's 3 capsules a day give 200 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.

Nature's Way Alpha Betic Cinnamon with Magnesium & Biotin declares 200 mg of elemental magnesium per serving as oxide, which needs 111 mg of magnesium oxide in each capsule, against 545 mg in a size 0 capsule at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range: it fits a size 0 capsule, the smallest of the three sizes compared here. No US retail price matched as of 2026-11-02; 10 of the 61 oxide labels in this registry have a matched price. NIH DSLD 213757, label dated 2020-02-26.

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 200 mg of oxide actually fit in one capsule, or do I need more than one?

Estimated salt mass versus assumed capsule capacity: Nature's Way Alpha Betic Cinnamon with Magnesium & Biotin implies 111 mg of magnesium oxide in each capsule to deliver 200 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: fits size 0, read at the most favourable hydration and the most units per serving.

How much elemental magnesium is actually in this label's filed magnesium lines?

Nature's Way Alpha Betic Cinnamon with Magnesium & Biotin files 1 magnesium line in NIH DSLD 213757; the selected primary line declares 200 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.
