1 in 3 Australians Don’t Get Enough Magnesium

According to the Australian Bureau of Statistics, the 2011 - 2012 National Nutrition and Physical Activity Survey found that one in three Australians over the age of two did not meet their Estimated Average Requirement (EAR) for daily intake of Magnesium, with 37% of males and 34% of females not meeting the requirement from their diet. The results of the national survey revealed that 72% of females and 61% of males aged 14 to 18 did not meet the EAR.

Magnesium is an essential mineral that plays a key role in a number of biochemical functions in the body including muscle and nerve function, blood sugar control, bone health and protein synthesis. Magnesium is widely distributed in both animal and plant products including unrefined cereals, green vegetables, beans and nuts.

The current Estimated Average Requirement (EAR) for Australian adults is 350mg/day for men and 265mg/day for women with the Recommended Dietary Intake (RDI) faring a little higher at 420mg/day and 320mg/day respectively for men and women.

Given that a significant portion of the Australian population might receive inadequate intake from their diet, many people may benefit from significant changes to their diet or adding a high quality magnesium supplement. Studies have found that magnesium forms such as magnesium chloride or magnesium citrate are more completely absorbed with superior bioavailability compared to magnesium oxide and magnesium sulfate.
