Hormones, the Nervous System & Why Less Is More for Health | ARTAH’s Rhian Stephenson

takeaways

1. Rhianne Stevenson shared how being chronically ill as a child, later linked to an allergy to the protein in milk, sparked her passion for nutrition and led to founding the supplement brand Arta.

2. The conversation explored a shift towards 'Health 2.0' — moving away from extreme diets and thinness-focused wellness towards nervous system regulation, connection and sustainable habits.

3. Rhianne framed 'the discipline of self-care' as prioritising nutrition, breathwork and stress management, especially as a working mother when sleep and training time are limited.

4. On biohacking, she noted women now make up a majority of clinic clients and argued fundamentals — protein, fibre, sleep, stress management, movement and a core supplement stack — matter more than expensive add-ons.

5. Fibre was discussed in depth, including its role in gut health and oestrogen detoxification, with only 1 in 10 UK adults reportedly reaching the 30g minimum, and the idea of using a low-FODMAP fibre supplement 'low and slow'.

6. They talked about supplement fundamentals like vitamin D, magnesium and omega-3s, realistic expectations, and the downsides of quick fixes and obsessively tracking wearables.
