Prolonged use of 20+ grams of Vitamin C may induce slight Magnesium deficiency. Muscle cramps are an obvious sign of magnesium deficiency.
Majkinetor, is this your experience? - Or you gathered it from other sources?
Because since 1 year I actually experience regularly short but strong pain from cramps on stretching or unusual movements in all parts of my body - while taking that much vit C since 2 years.
It's often in my throat (and very, very rare in my legs), so I suspected my bad thyroid values - or, due to fluctuating serum potassium and rather low sodium and calcium, some electrolyte imbalance from adrenal problems.
I didn't really considered low magnesium the culprit, because during the same time I took about 700mg/day of elemental magnesium in bio-available forms, beside as much from my diet. Too bad, none of my docs asked agreed to make a RBC-magnesium test yet.
Probably will have to experiment with higher doses of magnesium, if this could be the case with me..
