- Discover the Benefits of a Magnesium-Rich Diet
Magnesium is involved in more than 300 enzyme systems in the body. Just over half of the body’s magnesium is found in our bones and another third is found in our muscles and soft tissue.
Not only does it help ensure healthy muscle function, it also supports bone and heart health, can help relieve symptoms of stress and is required to maintain energy levels when dietary intake is inadequate. But official statistics show that one in three people in Australia aren’t meeting their daily requirements for magnesium.
Stress, drinking too much coffee, and eating too much salt can all contribute to low magnesium. Some medications may also affect levels. Early signs of deficiency include fatigue, nausea and a loss of appetite. As it progresses, muscle contractions, weakness and cramps, as well as numbness and tingling can occur.
