The Blood Labs Book Shop

The must-have books for every nutritional therapist.

I wrote the books I needed in clinic, designed to help you understand your clients blood test results with greater confidence, moving beyond basic reference ranges to explore patterns, context, and optimal interpretation.

Covering everything from the foundational blood work of fatigue, to more specialist areas such as cardiovascular disease, and paediatric blood testing, these books are practical, accessible resources to support your learning and your clinical practice.

  • Blood Labs 1 – Fatigue
  • Blood Labs 2 – Hormones (male & female)
  • Blood Labs 3 – Cardiovascular disease
  • Blood Labs 4 – Allergy, Intolerance, and Sensitivities
  • Blood Labs 5 – Autoimmune disease
  • Blood Labs 6 – Children

There’s a good reason why they’re on the reading list of all the major nutrition colleges in the UK, and why even I couldn’t be without them on a daily basis!
