Blaithin O'Neill

Registered Dietitian and Sports Nutritionist

BSc, PgDip, CORU


Are you looking to improve your nutrition but don’t know where to start?

Do you want to feel more confident in your body but sick of dieting and restricting certain foods that you enjoy?

Are you a fitness fanatic but lacking knowledge on how to fuel your body correctly to get that the most out of the sport that you love?

Have you been experiencing poor digestion for most of your life and sick of trying to cope with daily bloating, discomfort and feeling sluggish?

I am here to help

My name is Blaithin and I am a registered dietitian helping people make sustainable long lasting changes to their nutrition to improve their health physically and mentally.

My passion for working in nutrition comes from my first love of cooking. I want to help people understand that improving your nutrition does not need to be boring and prescriptive. It can be enjoyable, fulfilling and thrilling.



Too often we define our health by the number on the scales. I believe in a more holistic approach to ensure we are encompassing all aspects of the body to improve your health. My aim is to help you improve your nutrition and health through healthy habit formation.

With over 7 years of working in evidence based practise, you can feel assured you will be being guided on the basis of scientific research

I combine my years of experience of working in the public health sector alongside my training in sports nutrition and intuitive eating to provide you with a tailored supportive nutrition programme.

I want to take you from feeling lost to feeling empowered.
