Consumer advice
Check the Supplement Facts panel for "elemental magnesium" mg, not just the total complex weight — that's the number that determines dosing. If it's under 200mg elemental per serving, a cheaper single-form magnesium glycinate or citrate product will do the same job for less. Skip this if you already get enough magnesium from diet (nuts, leafy greens, whole grains) or take a multivitamin with magnesium already.

- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
