What Could Be Causing Your Muscle Twitches and Spasms?

5. Caffeine

Just as a shortage of nutrients can cause fasciculations, an excess of certain items is unhealthy, too. Caffeine is a stimulant, and that’s largely why people drink it. The energy boost is helpful, but it sometimes comes at a cost. Many health studies have linked caffeine to headaches, restlessness, twitching, and muscle spasms. Typically, these side effects only occur if there is too much caffeine in a person’s system. A healthy adult should limit their caffeine intake to 400 milligrams each day. A 12-ounce cup of coffee contains around 260 milligrams of caffeine.
