BFF Health was created with a clear vision: to be proactive about health, rather than waiting until we’re forced to react to a condition at the ‘bedside.’ We believe in tackling the root causes of health issues before they arise by empowering individuals with the tools and knowledge to take charge of their wellbeing. Our mission is to help people build – or rebuild – strong, sustainable nutrition foundations, giving them the confidence to nourish their bodies for long-term vitality. By focusing on prevention and optimisation, we aim to support lifelong health, so you can thrive at every stage of your journey.

Your BFF Team

Hayley Cullen-Xiang (Founder)


I began my journey as a microbiologist, drawn to the fascinating world of microbial life. From there, I worked as a medical researcher and laboratory manager, focusing on brain development and early neurogenesis.

My passion for translating scientific discoveries into tangible real-world benefits often clashed with the medical industry’s focus on cures over prevention. This frustration inspired me to return to university and retrain as an Accredited Practicing Dietitian (APD).

Now, I bridge the gap between science and health by working directly with clients to make a meaningful, preventative impact on their wellbeing.
