Magnesium is used by the body to help turn food into energy, according to the NHS.
Everyone between the ages of 19 and 64 years old should aim for between 270 and 300mg of magnesium everyday.
Most people should be able to get enough of the vitamin from their diet.
Leafy green vegetables, bread and nuts are all good sources of magnesium.
You could be at risk of a deficiency if you don’t eat enough magnesium. But, what are the signs to look out for?
Magnesium deficiency symptoms include weakness, apathy, tremors, and pins and needles, according to medical website Patient.info.
Without enough magnesium, patients may also have seizures, drowsiness or confusion.
If magnesium levels hit very low, it could even lead to a coma.
The widespread nature of deficiency symptoms means it can be difficult to pinpoint the exact source of their health problem, said the ‘Functional Dentist’ Dr Steven Lin.
Being tested for magnesium deficiency could reveal whether you should consider taking supplements, he said.
“If you’re worried you aren’t getting enough magnesium in your diet, you can add more in supplement form,” said Lin.
“When it comes to magnesium there are several types of supplement you can take and it’s important to know the difference between them.
“The mode of delivery also varies, you can take magnesium in tablet, powder, and transdermal forms.
“It’s better if you opt for a chelated magnesium supplement because these are more easily absorbed by your body.
“Other magnesium supplements can also be harsher on your digestion.”
But, taking too much magnesium can have negative health effects, the NHS warned.
Regularly taking more than 400mg of magnesium can cause diarrhoea.
It could also lead to vomiting, low blood pressure and facial flushing.
But, taking less than 400mg of magnesium supplements everyday is unlikely to be harmful, added the Department of Health.
Meanwhile, you could be at risk of a magnesium deficiency if you often struggle to fall asleep.
