If you are taking prescribed biotin you should discuss this with your doctor. You should take this test before you take any vitamin or mineral supplements.

From the expert

Most people suffer from fatigue and tiredness from time-to-time and it is one of the most common reasons why people visit their doctor. Tiredness is often as a result of a recent virus or infection or sometimes simply from doing too much. However, for some people, a lack of energy becomes chronic and everyday tasks become more and more difficult.

This test investigates 3 main causes of low energy and fatigue: iron deficiency anaemia, an underactive thyroid and low vitamin D, all of which can be improved through supplements or medication.
