How much elemental magnesium is actually in 100, 200 or 400 mg of taurate?
Magnesium taurate is 8.9% elemental magnesium by mass (Mg(C₂H₆NO₃S)₂, molar mass 272.58). Magnesium taurate has a molar mass of 272.58 against magnesium's 24.305, so 8.9% of its mass is magnesium. Every 100 mg of elemental magnesium from it needs 1,121 mg of the compound, calculated 2026-10-17.
computedThis defined salt has one calculated elemental fraction from its formula.

Estimated salt mass versus assumed capsule capacity
0 of 2 capsule labels naming taurate alone are above the assumed size 000 capacity at powder density 0.8 g/mL, against 8 of 137 capsule labels across the audited registry. 0 fit size 0 or 00 and 2 need size 000. This is computed with a stated assumption of powder density 0.8 g/mL, the top of the usual 0.6–0.8 range and the most favorable mass per capsule.

Is a label called taurate really taurate, or mixed with another salt?
0 of 4 labels naming taurate also name another form as of 2026-08-10. The table counts partner names on filed labels; a named blend does not establish the elemental contribution of each salt. Naming one salt is not the same as fitting it: 0 of 2 capsule labels naming taurate alone exceed size 000. Open the full label list to inspect individual records.

I need 200 mg of actual magnesium. What changes in compound weight and capsules between taurate and other forms?
For 200 mg of elemental magnesium, taurate needs 2,242 mg of compound, against oxide at 332 mg. Size 00 holds about 730 mg at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range. Each row uses the stated elemental fraction; hydration ambiguity stays a range, and any price comparison remains within a single salt.
