Psychoneutrogenomics: Personalizing Nutrition for Mood, Focus, and Mental Resilience

If you have cycled through diets, supplement stacks, DNA reports, and gut protocols only to watch the improvement fade, the problem was never your discipline. It was the order.

Psychoneutrogenomics is the study of how three biological layers — your genes, your gut's anaerobic ecology, and your nutrient intake — interact to shape your mood, focus, and mental resilience. It is also the study of why those layers must be addressed in sequence, and what happens when they are not.

Drawing on nutritional genomics, gut microbial ecology, and nutritional psychiatry, this book presents a single integrated framework for the first time:

·        The terrain: how gene variants like MTHFR and COMT shift your nutrient requirements without determining your fate

·        The engine: why your colon is anaerobic, and why keystone species like Akkermansia muciniphila, Faecalibacterium prausnitzii, and Roseburia matter more than any probiotic on the shelf

·        The signal: how cofactors, omega-3 fatty acids, and amino acid timing convert biological potential into actual neurotransmitter output

·        The method: a four-phase sequencing protocol, a testing prioritization framework, and a discipline for running your own personal experiment

Ecology first. Nutrients second. Gene-targeted refinement third.

This is not a diet book. It is not a promise of a cure. It is a map for the reader who has been told their labs are normal and their symptoms are not — and who is ready to understand their own biology well enough to work with it.

Honest about the science. Honest about the limits. Written for the reader who wants the real answer.

Perfect for readers of nutritional psychiatry, functional medicine, gut-brain science, and anyone who has ever wondered why personalized nutrition never felt personal.
