Sophie Pigott

I am a qualified Holistic Clinical Nutritionist. I graduated in 2021 with a Bachelor of Health Science in Nutritional and Dietetic Medicine. My passion is empowering individuals to fall in love with taking care of themselves, through nourishing foods & a mindful lifestyle. My approach to practice is thorough, holistic, evidence-based, and individualised to each client.

I specialise in women’s health, mental health, including stress, anxiety, depression and disordered eating, nutritional deficiencies, gut health, immune support, and pre conception, pregnancy, and post natal care.

I thrive on simple, vibrant, wholesome living across all aspects of my life. Cooking, creating recipes, teaching yoga, and the swimming in the ocean are my therapy. I have always been into healthy eating, movement, and the power of the mind. Through my own personal challenges I have gained so much knowledge about myself and gained a wealth of empathy towards others. I now commit myself to living life to serve and support others and to be the best version of myself I can possibly be. I believe in living a wholesome, sustainable life free of diet culture, yet full of nourishing foods and self love.

Supporting your body with an abundance of whole foods, living an active lifestyle, and mindfulness are the keys to change all aspects of your life for the better. I am here to help kickstart your journey to optimal health and balance.
