Magnesium is an essential mineral for over 300 enzymatic processes within the body, and without it, these processes are impaired. Dietary intakes are often found to be low, and low levels are exaggerated due to modern lifestyle factors which increase demand such as stress, smoking, alcohol consumption and a high sugar intake. Magnesium is required for normal psychological function and normal nerve function and is often found to inadequate in people with low moods and low mental outlooks. Magnesium is also required for sleep and the relaxation hormone GABA. Magnesium is required directly for the energy production cycle for the creation of energy. It is needed for the normal function of muscles and may help to prevent cramping and stiffness. Magnesium is particularly beneficial for the heart muscle and for regulating high blood pressure. As a key structural mineral in bones and teeth, adequate levels of magnesium are required for their maintenance, particularly for weak bones and osteoporosis.
