Nutritional therapy is a type of treatment in which nutrition is used to remove the imbalances which can cause ill-health. Another important aspect of the therapy is providing guidance on healthy eating and the prevention of future disease. The aim of nutritional therapy is for the client to achieve optimal levels of health and well-being.

The approach of the therapy is holistic; the treatment aims to treat the underlying cause of symptoms, rather than just suppressing them. As this is a complementary therapy, it can be used alongside conventional medicine.

An important belief underpinning nutritional therapy is that each client has an individual biochemistry, so treatment is tailored to the individual requirements of each client. Treatment will usually involve changes to the client’s diet or way of eating, and may also include supplementation with vitamins, minerals and other natural nutrients.
