Anxiety & Nervous System Regulation
"GABA-Glutamate Balance, Copper/Zinc Ratios & Sympathetic Dominance"
Chronic anxiety is frequently driven by excitatory glutamate toxicity, elevated copper-to-zinc ratios, and impaired GABA synthesis due to nutrient depletions.
From Lisa Cutforth — Clinical Nutritionist
"Anxiety is often an electrical and chemical storm caused by elevated copper or low GABA cofactors. Restoring elemental balance calms the neural firing."

Cellular Pathways
Biochemical Mechanism & Systems Interplay
The body does not operate in silos. Here is the biochemical reality of how nutrient cofactors govern anxiety & nervous system regulation.
Copper stimulates norepinephrine production and reduces dopamine breakdown. Excess copper combined with deficient zinc creates hyper-excitability in the central nervous system and heightened panic responses.
"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.

- Urinary Catecholamines & GABA/Glutamate Ratios

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.
