What are Optimal Magnesium Levels?

The first step to understanding magnesium levels is to know exactly what they should be. A blood test can be done to check how much magnesium you have in your body. If you are low on this vital mineral, you can easily top up with magnesium supplements.

To reach this optimal mineral saturation, Public Health England has recommended the magnesium daily intake for each age group:


Recommended daily dose of magnesium



Pregnant women


Children aged 15-18


Children aged 11-14


Children aged 7-10


Children aged 4-6


Children aged 1-3


Children aged 7-12 months


Children aged up to 6 months


Normal magnesium levels should fall between 1.7 and 2.2 mg/dL.

5 Signs of Magnesium Deficiency

Having too low a level of magnesium could lead to a mineral deficiency. Magnesium deficiencies have a number of signs to look out for:

  • Poor Sleep - magnesium plays a vital role in sleep. Low magnesium levels could leave you struggling to nod off at night. Sleep supplements fortified with magnesium can help you experience a restful sleep.
  • Fatigue - this mineral is essential in the function of muscles, having insufficient magnesium levels could lead to a buildup of lactic acid. This in turn can leave you feeling tired and fatigued. Ensuring you take a natural energy supplement alongside magnesium supplements could help to rectify this.
  • Decreased Appetite - decreased magnesium levels have been linked to a reduction in appetite. Increasing your levels should help to counter this.
  • Nausea - an early sign of low magnesium levels is nausea and even vomiting.
  • Weakness - as this vital mineral is important for muscle function, a low level can cause you to feel weak - especially when in combination with a reduced appetite.

If you are experiencing any of these symptoms, you may have low magnesium levels, this can also be known as hypomagnesemia. If you have any health concerns you should always speak to your doctor.

  • Gastrointestinal diseases - such as celiac and Crohn's disease

Causes of High Magnesium Levels

Our kidneys usually filter excess magnesium levels from our blood and expel them in our urine. One of the key causes of high magnesium levels is kidney failure, when this organ stops functioning properly. However, some people may have this condition simply from consuming too much of the mineral in their diet.
