Magnesium plays a vital role in bone formation and maintains bones density. It helps the body utilise the nutrients that are needed for strong bones, like calcium and vitamin D. There are links of greater bone density in older men and women who have a higher dietary magnesium intake.

Magnesium plays an important role in maintaining healthy levels of GABA, a neurotransmitter that promotes sleep. Some research indicates that supplementing with magnesium can improve sleep quality, especially in those who suffer from poor sleeping patterns. A common symptom of magnesium deficiency is insomnia as some people with low levels often experience restless sleep.

Studies have found that low dietary and serum magnesium have been associated with cardiovascular disease, especially in men. This supports findings that magnesium helps regulate heart rhythm, blood pressure and the production of cholesterol, all contributing towards the prevention of cardiovascular disease.

Deficiencies in magnesium have been linked to stress and anxiety and early studies suggest that taking magnesium supplements may help alleviate these symptoms. This may be due to when having low levels of magnesium in your body, your adrenal glands that produce the hormone adrenaline are affected and so this can increase your stress levels.
