Functional Medicine Nutrition

The Functional Medicine (FM) model was developed by bio-scientists and medical doctors almost 30 years ago and is used by doctors and nutritional therapists worldwide. It is based on the understanding that not only genetics but also diet, environmental toxins and lifestyle choices can have an accumulative effect over the years which may result in the development of disease. Rather than addressing symptoms we look at root causes of symptoms and by identifying the complexities and imbalances in your health concerns, we can give recommendations that are specific to you.


Functional Medicine operates on these basic principles:

  1. While we share the same physiological make up, we are all unique individuals with different ways that we react and respond to our environment.
  2. By understanding that the body has interlinking body systems we can start to observe the root causes of imbalances in our health.
  3. By adjusting our nutrient intake and lifestyle choices, we can start to address these root causes.
  4. Our ancestry, genetics and a lifetime of diet and lifestyle choices can have an accumulative effect resulting in certain health concerns. In the same way our present health choices can affect our future. We would like to help guide you on your life choices.
