Magnesium is a mineral used in more than 300 biochemical functions in the human body. It is involved in the functioning of nerves and muscles, heartbeat, energy production, regulation of blood pressure, regulation of blood glucose levels, and support of the immune system. The average adult human body contains about 25 grams of magnesium: 50 to 60 percent is found in bones, 1 percent is found in blood serum, and the rest is found in soft tissues.
The normal serum level of magnesium ranges between 0.75 to 0.95 millimoles per liter, or mmol/L. To maintain this level, humans need a daily intake of between 30mg for a newborn to 420mg for adults aged 51 years or older. Low magnesium occurs when serum level falls below 0.75mmol/L. Because of its involvement in many body functions, low levels can disrupt these functions and lead to 1.
Low Magnesium Symptom #1: Chronic Fatigue
Fatigue is one of the most common symptoms of low magnesium. Low levels affect the production of energy and the workings of muscles and nerves. When the body does not produce optimum levels of energy, some processes will be adversely affected. Additionally, because magnesium is required for the proper use of potassium in muscles, reduced magnesium levels can mean that the muscles do not function normally.
Inadequate magnesium in the body can therefore lead to fatigue. However, this does not mean that you have magnesium deficiency every time you experience fatigue. Rather, you are more likely to have low magnesium if you have chronic fatigue.
