Nutritional therapy is the promotion of health through personalised nutrition and lifestyle support. It is a whole-body approach to nutrition and lifestyle medicine that addresses the potential underlying causes of ill-health, rather than focusing on symptoms.

Evidence-informed, it involves a wide range of tools which are used to assess individual health status and identify potential nutritional imbalances that may be contributing to symptoms. The focus is always on the individual client.

Many chronic conditions, as well as day-to-day fluctuations in health and wellbeing, can be linked to individual nutrition and lifestyle. Quite often, people see stark improvements in their health when they implement changes to their diet.

Nutritional therapy can support individuals with a range of concerns, including:

  • Digestive issues
  • Hormone imbalances
  • Weight loss
  • Migraines
  • Poor sleep
  • Stress
  • Skin conditions
  • Aches and pains
  • Energy
  • Diabetes
  • Autoimmune diseases
  • General wellbeing

What does a nutritional therapist do?

Nutritional therapists are fully qualified practitioners who work with individuals on a one-to-one basis to support health and wellbeing. Their advice is always personalised to the individual, rather a one-size-fits-all approach. They take into account your health journey, health goals and dietary preferences. After all, what works for one person may not work for another.
