Functional Medicine Practitioner Steve Grant 2

Hi, I’m Steve.

I have been a Functional Medicine Practitioner for over 20 years and during that time have supported clients through a variety of health, performance and physical transformations.

I operate both from my Functional Medicine clinic in Marylebone, central London and online via video consultations.

I have worked with thousands of clients to date and won ‘Outstanding Practice’ awards for my work within Functional Medicine.

In a world of constant demands, conflicting health advice, the world’s information at our fingertips, and ever-changing priorities, many people struggle not with motivation, but with clarity, consistency, and implementation.

This is where professional guidance, accountability, and experience matter most, especially when delivering a Functional Medicine-based health transformation.

The reality most clients face…

Most people seeking support today are not short of information. They are overwhelmed by it.

Clients often arrive having tried multiple diets, supplements, practitioners, protocols, or tests.

Many have spent hours using online resources, AI tools, or search engines to navigate their situation, yet still feel stuck, frustrated, or unsure which direction to take next.

They may be managing complex or chronic health concerns, juggling demanding careers and family life, or simply finding that their health has gradually slipped down the priority list.

The reality is, more information alone doesn’t equal better results.

How we work

Steve Grant Health provides personalised Nutrition and Functional Medicine support for individuals seeking clarity, consistency, and sustainable improvements in their health.

With over two decades of clinical experience, the focus is on helping clients navigate complexity, implement realistic strategies, and achieve meaningful long-term outcomes.

Rather than one off consultations, most clients achieve better outcomes through structured, ongoing support.

This provides clarity, accountability, and the ability to adapt recommendations as circumstances change.

Support focuses on prioritising what matters most, translating data into action, and maintaining momentum over time.
