ADHD & Cognitive Focus
"Dopamine Pathways, Iron Co-factors & Pyrrole Depletion"
Attention deficits and executive dysfunction correlate with impaired dopamine receptor density, low serum iron/ferritin, zinc deficiency, and elevated urinary pyrroles.
From Lisa Cutforth — Clinical Nutritionist
"Before labeling a brain as inherently deficient, we must optimize ferritin, zinc, and essential fatty acids — the literal building blocks of attentional control."

Cellular Pathways
Biochemical Mechanism & Systems Interplay
The body does not operate in silos. Here is the biochemical reality of how nutrient cofactors govern adhd & cognitive focus.
Dopamine synthesis relies on tyrosine hydroxylase, which requires iron, oxygen, and tetrahydrobiopterin (BH4). Zinc modulates dopamine transporter activity and NMDA receptor function.
"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.
- Serum Ferritin (Optimal > 50-70 ng/mL for dopamine)
- Urinary Pyrroles (HPL)
- Zinc / Copper Balance
- Essential Fatty Acid Analysis

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.
