A holistic approach

to your health

My name is Nicole Gray, a naturopath and nutritionist based in Singleton, and here you will find information about me and my philosophy on offering support and education with: learning and behavioural difficulties, family health, mental health, preventable diseases, nutritional deficiencies etc. Please scroll down or click on the headings to take you to the information.

I am really looking forward to meeting you soon and being able to help you achieve your wellbeing goals.

About Me

I am originally from Germany and arrived in Australia in 1998. In 1999 I made Singleton my home and have been very happy here. Most of my life I have been working in hospitality and have always had a great interest in nutrition, having followed every weight loss diet under the sun with mixed results. This made me realise that there has to be more to it than just going on fad diets and restricting the foods you love.

The catalyst however, for me to study Nutritional Medicine and Naturopathy was mine and my families health. In addition, working as a canteen manager at a public school, I have had insight into the effects of dietary choices on children’s health and behaviour.

Countless conversations over the years have made me realise that many are seeking help in taking theirs and their families wellbeing into their own hands but don’t know where to start. I was in the same boat. After asking many questions and not getting the answers that I felt comfortable with I finally found someone who was able to steer me onto an alternative path to health.

My family had some amazing results incorporating nutritional changes, supplementation, exercises and the use of a variety of healthcare professionals. I feel the knowledge I have acquired through my studies and my life experience will be of benefit to the Singleton community and beyond and would love to share it with families in need.

I am passionate about a holistic approach to your wellbeing and hope that you will allow me to be part of your journey to optimal health.

Yours in health and happiness,
Nicole Gray

My Philosophy

As a nutritionist and naturopath my focus is on the interaction of gastrointestinal health, vitamins and minerals, dietary and lifestyle choices to the optimal function of the brain and general wellbeing.

Mental health, learning and behavioural difficulties, autoimmune diseases and other preventable illnesses have been linked to an unbalanced gastrointestinal micro flora, nutritional deficiencies and inflammation.

The definition (online medical dictionary) of nutritional medicine underpins my approach:
1. Use of food and nutrition as a medicinal approach.
2. Supplementation of diet with nutrients, intermediary metabolic products, and probiotics to prevent illness and improve health and healing.



With the above in mind I believe in the inherent capability of the body being able to heal itself given the right nourishments and lifestyle.

My 7 principles focus on Nutrition, Exercise, Wellness, Support, Mindfulness, Self-respect and Positivity taking an assertive and holistic approach to your health. In addition my aim is to educate you to be able to make informed choices and take your health into your own hand.
