What is a soap remedy for leg cramps?

While some believe that placing a bar of soap under the bed at night helps to stave off leg cramps, medical experts debunk this belief as magical thinking. According to the belief, the soap allegedly gives off magnesium, which can help leg cramps.

Medical experts dispute that using soap for cramps actually works. Muscle cramps are usually caused by a lack of minerals and dehydration. Instead of using a bar of soap to fight cramps, experts recommend rehydrating with a sports drink. Massage therapy can also help alleviate cramps. Continued muscle cramps could be a sign of an underlying medical condition that needs to be diagnosed and treated by a medical professional.
