About Simplex Health

Simplex Health is a clinical nutrition practice based in functional medicine concepts empowering our clients through innovative and progressive approaches to build a sustainable lifestyle.

Our sustainable approach requires no complex calorie counting, simplified meal planning and real food.  Where appropriate, we incorporate the sensible use of pharmacologics to assist in the re-balancing process.


We believe the path to better health, effortless weight loss, reversing 'dis-ease' and igniting your energy levels must move beyond conventional thinking. SIMPLEX HEALTH unites a fresh approach applying our doctor-approved, integrative programs to re-balance and harmonize the whole person.

What is a ‘healthy’ food?

1. It promotes a healthy psychological response
2. It promotes a healthy hormonal response
3. It supports a healthy gut
4. It supports immune function and minimizes inflammation
