Can vitamins prevent leg cramps?

Vitamins can help to prevent and treat leg cramps, especially within individuals who have a calcium, magnesium or potassium deficiency which can cause muscle spasms and cramps in the leg, according to WebMD. A daily multivitamin and foods rich in calcium and magnesium can help ward off leg cramps.

Beyond increasing daily vitamin intake, individuals at risk for leg cramps should also increase fluid and water intake, stretch muscles regularly, especially before and after exercise and at bedtime and limit or avoid drinks with alcohol, according to WebMD. Pregnant women, who are at risk for leg cramps, should heavily increase calcium intake to prevent muscle spasms.
