Biochemical Mental Health
"Walsh Protocol, Methylation & Neurochemical Individuality"
Mental health conditions are intimately linked to nutrient imbalances, methylation status, pyrrole disorder, and heavy metal toxicities that disrupt neurotransmitter synthesis.
From Lisa Cutforth — Clinical Nutritionist
"By applying the Walsh Protocol and targeted nutrient therapy, we balance neurotransmitter levels at the genetic and biochemical level, providing profound relief without relying solely on pharmaceuticals."

Cellular Pathways
Biochemical Mechanism & Systems Interplay
The body does not operate in silos. Here is the biochemical reality of how nutrient cofactors govern biochemical mental health.
Undermethylation reduces S-adenosylmethionine (SAMe), impairing serotonin and dopamine synthesis. Overmethylation leads to excessive dopamine activity and anxiety. Pyrrole disorder causes severe depletion of zinc and active vitamin B6.
"When we correct enzymatic blocks with bio-available cofactors, physiology realigns naturally."
Standard blood ranges are designed to detect acute disease. We look for optimal functional biochemistry.
- Whole Blood Histamine (Methylation marker)
- S-Adenosylmethionine (SAM) / S-Adenosylhomocysteine (SAH) Ratio
- Urinary Hydroxyhemopyrrolin-2-one (HPL / Pyrroles)
- Plasma Zinc & Serum Copper Ratio
- Ceruloplasmin

Connected Health Pillars
Women's Health & Hormones
Hormone synthesis, follicle maturation, and endometrial cycling require precise nutritional inputs across all 28 days. From heavy menstrual bleeding to perimenopausal transition, targeted nutrition balances oestrogen detoxification, luteal progesterone support, and thyroid interactions.
Gut-Brain Axis & Microbiome
Over 90% of the body's serotonin and a significant portion of GABA are generated in the gastrointestinal tract. Intestinal dysbiosis and leaky gut directly trigger neuroinflammation through bacterial lipopolysaccharides (LPS).
Adrenal & Stress Physiology
Chronic stress alters the hypothalamic-pituitary-adrenal (HPA) axis, depleting vital cofactors required for cortisol synthesis, catecholamine regulation, and thyroid activation.
