Do you need more magnesium?

Paul Keogh shares some of the clues that indicate you might benefit from topping up your magnesium levels.

magnesium for health

Did you know that magnesium plays an important role in many functions in the body, and effects our muscles, energy and the health of our bones? Many Australians could include more magnesium in their diet. Up to one in every three people aren’t getting enough magnesium.1 Here are some of the clues that you might benefit from topping up your magnesium levels.

You get muscle cramps

If you aren’t getting enough magnesium in your diet, you might experience muscle cramps and twitches.2 This is because magnesium is responsible for the contraction and relaxation of our muscles. It does this by helping to balance calcium levels in our muscle cells.2

You’re tired

Are you lacking in energy? One of the most important roles that magnesium plays in the body is the production of energy. It is used in our cells in the formation of a molecule that provides energy for the majority of metabolic processes in the body, called adenosine triphosphate (ATP).2

You exercise

Magnesium is excreted from the body in water, so if you exercise, chances are you may lose some magnesium through your sweat.3 Increasing your dietary intake of magnesium could help compensate for this loss.3

You get PMS

Women who experience premenstrual syndrome (PMS) have lower levels of magnesium in their plasma than women who don’t get PMS.4 If you experience PMS symptoms such as mood changes, irritability or breast tenderness, then taking magnesium might help provide some relief if your dietary intake of this important mineral is inadequate.4

You’re over 51 years old

Research from the Australian Bureau of Statistics (ABS) indicates that the diets of many older Australians don’t supply the recommended quantities of magnesium.1

Almost half of all Australian men over 51 years old (46.5%) don’t consume their estimated average requirement (EAR) of 350mg per day, while 30% all women of the same age consume less than their EAR (265mg per day).1

Because magnesium is important for maintaining healthy bones, consuming enough magnesium is important for older people.2

foods high in magnesium

Where can I get more magnesium from?

There are many foods you can include in your diet that are rich in magnesium, including brazil nuts, almonds, cereals (oats, all bran), brown rice, spinach, chickpeas and bananas.2

Choosing a magnesium supplement

When selecting a supplement, choose a product that contains a highly bioavailable, easily absorbed source of magnesium, such as magnesium glycinate.

If swallowing large tablets is difficult for you, consider taking a powdered supplement that can be dissolved in water, smoothies or juice – these have the added benefit of being suitable to use in your drink bottle when you’re training.
