Roll Call does not check drug interactions or assess personal safety.
A mineral salt combining magnesium with ascorbic acid (vitamin C), used as a less acidic, 'buffered' way to deliver both nutrients in one compound.
Why it’s used
Taken as a source of vitamin C and magnesium, often chosen by people looking for a gentler form of vitamin C on the stomach.
What the evidence is for
preventing vitamin C and magnesium deficiency and supporting normal nutrient function.
What the evidence says
The evidence base here rests on vitamin C and magnesium individually, both well established for preventing deficiency and supporting normal physiological function per NIH ODS; the magnesium-ascorbate salt form itself has not been separately studied for superior absorption or effect compared to other forms.
Dose studied
65–2000 mg — adult RDA up to tolerable upper intake level for vitamin C, per NIH ODS.
Context
NIH ODS dietary reference intakes for vitamin C and magnesium are based on studies of the nutrients broadly, not this specific combined salt form, so dosing data reflect the individual nutrients rather than the compound itself.
