The World Health Organization estimates that 75% of people in some western countries do not consume enough magnesium. Because this mineral is essential for over 300 reactions throughout the body, insufficient magnesium can produce a number of symptoms including: impaired recovery, low energy levels, poor sleep, feelings of stress and anxiety, muscle cramps or restless legs, and more. Supplementing high quality magnesium is one of the easiest ways to make noticeable improvements to our health.
