Magnesium
Magnesium is involved in more than 300 enzyme reactions, from making energy and protein to keeping your heart rhythm steady and your muscles relaxed.

Why it matters
Most of it lives in bone and inside cells, so the blood level is only a rough guide to your total stores. A low magnesium also makes it hard to keep calcium and potassium normal.
What a result can mean
Lower than the range
Low magnesium is commonly caused by alcohol, diarrhoea, diuretics and long-term use of acid-reducing medicines such as omeprazole, and can cause cramps, tremor and palpitations.
Higher than the range
A high magnesium is uncommon and is usually seen with kidney disease or excess intake from supplements, laxatives or antacids.
What can help
Leafy greens, nuts, seeds, beans and whole grains are good sources. Supplements are sometimes recommended for a low level, alongside a review of any medicines that might be the cause.
