How Much is Enough?
A macromineral, magnesium, is one of seven minerals that are required in larger quantities (unlike minerals such as zinc and iron, which are needed in much smaller amounts). The NHS guidelines recommend a daily intake (RDI) of 300mg for men and 270mg for women. But, whilst most people don’t meet their daily intake, it can be found in many different foods.
Too much alcohol, caffeine, and sugar can cause a depletion of magnesium within the body.
If you’re not getting enough, you may start to notice some rather unpleasant symptoms. Magnesium deficiency, known ashypomagnesia, can cause nausea, vomiting, muscle cramps, anxiety and even changes in the heart’s rhythm, as well as making it harder to sleep.
