Why magnesium deficiency could be silently harming your health

Magnesium plays a vital role in keeping the body healthy, yet many people may not get enough of it. The mineral supports over 300 biochemical processes, from energy production to muscle function. Without sufficient levels, symptoms like fatigue, muscle weakness and even depression can appear.

The human body cannot produce magnesium on its own. Instead, it must come from food or supplements. Adult men need around 420mg daily, while women require about 320mg. Despite its importance, diagnosing a deficiency is tricky—blood tests often miss low levels because most magnesium is stored in bones and tissues.

Common signs of deficiency include nausea, tingling in the limbs, and irregular heart rhythms. Over time, it may also contribute to high blood pressure, insomnia, and weakened muscles. For those considering supplements, magnesium glycinate is a gentle option that the body absorbs well.

Taking magnesium 30 to 60 minutes before bedtime may help relax muscles and improve sleep quality. Studies suggest it can also lower blood pressure, boost physical performance, and support metabolic health. However, experts advise speaking to a GP before starting supplements, as self-diagnosing a deficiency can be unreliable.

Magnesium remains essential for heart health, nerve function, and strong bones. While supplements offer benefits, a balanced diet and medical advice are key to avoiding deficiency. Those experiencing persistent symptoms should seek professional guidance before making changes.
