FAQs
What can I learn from a magnesium test?
Our test can tell you if your magnesium levels are normal and whether you need to eat more magnesium-rich foods. Magnesium is in fibre-rich foods such as green leafy vegetables, avocados, bananas, wholemeal bread, brown rice, fish, and meat. Too much magnesium is often caused by over-supplementation or taking too many antacids or milk of magnesia.
What are the symptoms of too much magnesium?
Symptoms of excess magnesium include breathing problems, skin and eye irritation, flu-like symptoms, and an upset stomach. Low magnesium can cause muscle twitching and cramps, fatigue, osteoporosis, an irregular heartbeat, and high blood pressure. Low magnesium is associated with heart disease, atherosclerosis, stroke, and diabetes.
What is magnesium?
Magnesium is a mineral that supports proper muscle, nerve, and enzyme function. It helps your body make and use energy and is needed to move other electrolytes (potassium and sodium) into and out of cells. Most magnesium is found in your bones and inside your cells. Only a tiny amount is usually present in your blood.
