Do you often feel anxious? Are you easily stressed? If so, you may benefit from topping up your magnesium intake. Signs that you may be low in magnesium include anxiety, low resilience to stress, poor sleep, fatigue, restless legs, eye twitches, PMS, muscular cramps and low mood. Magnesium is an essential mineral needed for over 300 processes in the body including energy production, muscle and nerve function as well as the structure of bones and teeth. This powerful mineral is also proven to aid relaxation and contribute to a reduction in stress and fatigue. Magnesium may be depleted in the body by a diet low in wholegrains, vegetables, nuts and seeds and a high intake of sugar and refined foods.
