About 70% of the population gets random muscle twitches. The medical term for this is fasciculation—spontaneous involuntary muscle contraction and relaxation. This could happen to your eyelid, arms, hands, fingers, legs, feet, or tongue. 

There is even a medical condition called benign fasciculation syndrome. I believe this condition is really a nutritional deficiency. But, the typical treatment is cognitive behavioral therapy, anti-depression medication, and calcium channel blockers. 

In my opinion, random muscle twitches are caused by a magnesium deficiency. About 70% of the population also has a magnesium deficiency. Leafy greens are rich in magnesium. 

Other symptoms of a magnesium deficiency: 

• Fatigue 

• Muscle cramps 

• Anxiety 

Other potential causes of a muscle twitch:

• High calcium 

• Low vitamin D

• Alkalosis (potentially caused by a high carb diet or low potassium)
