Magnesium – maybe the one nutrient you’re not getting enough of?

15 Aug 2016

 

Do you eat well? Think you’re ticking all the nutrition boxes? Unless you are eating the particulars, you may not be meeting your magnesium requirements.

 

Magnesium functions

 

Magnesium is a mineral that is abundant in any healthy body. It is involved in over 300 chemical processes, hopefully happening in you right now. Some of these include:

 

  • Energy production

  • Protein synthesis

  • Blood glucose control

  • Blood pressure regulation

  • DNA synthesis

  • Muscle contraction

  • Normal heart rhythm

  • Nervous transmission

 

The adult body contains about 25g of Magnesium with up to 60% of this found in the bones and most of the rest of it, found in soft tissues, like skeletal muscle.

 

Magnesium balance 

 

Your kidneys manage magnesium balance in the body, with most of us urinating ~120mg out into the toilet each day. If you’re not consuming enough , you're body is quite clever at conserving it by reducing urinary excretion.

 

 

Magnesium tests

 

 

 

You can get your magnesium levels checked through blood testing, however your blood levels of magnesium have little correlation with your overall total body magnesium levels... So blood tests may not be the best marker to check for healthy magnesium status. For a more comprehensive analysis, it would be advised to have lab tests checked with a thorough clinical assessment, including detailed diet history.
