Muscle twitches and cramps

Magnesium deficiency causes twitches, tremors, and muscle cramps. Deficiency might result in seizures in the worst-case scenario.

Scientists believe that a greater flow of calcium into nerve cells causes overexcitation or hyperstimulation of muscular nerves, resulting in these symptoms. While magnesium supplements may help reduce muscular twitches and cramps in certain people who have a deficiency, one study found that they are ineffective in treating muscle cramps in older adults. In other groups, more research is required. Keep in mind that involuntary muscle twitches might be caused by a variety of factors. Stress or too much coffee, for example, might cause involuntary muscle spasms. They might also be a sign of neuromuscular diseases such as muscular dystrophy, multiple sclerosis, myasthenia gravis, or a side effect of some medications. While twitches are common, if your symptoms persist, you should consult a doctor.
