Fatigue and Weakness
Magnesium deficiency may cause fatigue, weakness, and muscle cramping. Weakness is a common symptom of magnesium deficiency because the mineral is required for muscle contraction. The reason why people who are suffering from a magnesium deficiency may feel weak and tired is that the body needs magnesium to produce energy. Without enough magnesium, the cells can’t make ATP, the energy molecule that supports bodily functions.
Fatigue is one of the most common signs of a severe medical condition, so if you are experiencing it along with other symptoms like weakness and cramping, it could be due to low levels of circulating magnesium.
