Science-first approach

As an evidence-based practitioner, Rhiannon is committed to the benefits of a scientific approach to nutrition. She has worked as a consultant to many well-known food brands including Deliveroo, Wagamama, Alpro, Yeo Valley, and Little Freddie, refining their menus, product ranges, and cooking methodology. Rhiannon has also advised on nutrition and wellbeing at Six Senses, Four Seasons Hotels & Resorts, Microsoft, Samsung, and Coty.

What our clients say

I was privileged enough to work with Rhitrition’s Sarah Elder, following severe medical and psychological trauma. She gently and expertly addressed my fears, eliminated the physical pain I was experiencing, and transformed the way I live my life. I can’t thank Sarah and the Rhitrition team enough.”

Anna N.

For the first time, I feel empowered to make my own food choices rather than guilted or shamed into them. Rhiannon is the first nutritionist I’ve come across, who incorporates psychological mindset, daily living practices and nutritional theory. Rhitrition has completely changed my life!”

Carianne O.

We recognise one approach doesn't suit everyone

You needn’t be worried about hard-to-commit-to and complicated plans, we firmly believe that getting back to basics and keeping nutrition simple is the easiest way to maintain a healthy body.
