Magnesium is a mineral that is vital for our body. It is required for growth and maintenance of our muscles and bones as well as the functionality of nerves, muscles and other areas of the body. Magnesium also aids the movement of faeces through the intestine as well as neutralising stomach acid. Without magnesium our muscles become fatigued and tight.

Magnesium is typically used to treat or prevent magnesium deficiency. However there are many other uses for magnesium such as:

  • Laxative for constipation
  • Diseases of the heart and blood vessels
  • Attention deficit-hyperactivity disorder (ADHD)
  • Anxiety
  • Chronic fatigue syndrome (CFS)
  • Kidney stones
  • Multiple sclerosis (MS)
  • And many other medical conditions

Magnesium is to be orally consumed. Be sure to accurately follow the instructions on the product package or given by your doctor. Here are some general guidelines for taking magnesium:

  • It is recommended to take magnesium tablets with a meal in order to reduce diarrhoea or an upset stomach.
  • Take your dose with a glass of water
  • Do not chew or crush your tablet (or capsule) – this can increase the risk of experiencing side effects
  • Do not take the magnesium tablets more frequently than recommended

If you experience any of the following side effects seek immediate medical attention and cease use of magnesium:

  • Hives or rash
  • Swelling of the face, lips, tongue, or throat
  • Difficulty breathing
  • Nausea or vomiting
  • Slow or fast heart rate
  • Reddening of the skin
    Tingling or warm sensation of the skin
  • Itching
  • Unusual fatigue
  • Dizziness

If you experience any of these symptoms continue use of magnesium, however contact your doctor:

  • Upset stomach
  • Bloating or gas
  • Diarrhoea
  • Pregnancy and breast-feeding:There is no evidence to suggest that magnesium is detrimental during pregnancy or breast-feeding. However, it is best to consult your doctor about if magnesium is an option for you or what amounts you should take.
  • Bleeding disorders: Individuals with bleeding disorders may have an increased risk of bleeding or bruising due to magnesium slowing blood clotting.
  • Heart block: Individuals with heart block should not take high doses of magnesium
  • Kidney problems: It is not recommended for individuals to take magnesium if they have kidney problems due to the kidneys being unable to clear out magnesium from the body. As a result the magnesium can reach dangerously high levels in the body, causing serious health issues.
