Sleep Architecture & Melatonin
"Circadian Rhythm, Pineal Synthesis & Glymphatic Clearance"
Quality sleep is the primary period for glymphatic brain detox and cellular repair. Disrupted sleep stems from circadian mis-alignment, low melatonin synthesis, or nocturnal cortisol spikes.
From Lisa Cutforth — Clinical Nutritionist
"Sleep is not passive downtime — it is active neurological maintenance. Fixing sleep requires setting light cues and supplying pineal cofactors."

Cellular Pathways
Biochemical Mechanism & Systems Interplay
The body does not operate in silos. Here is the biochemical reality of how nutrient cofactors govern sleep architecture & melatonin.
Serotonin is converted to melatonin in the pineal gland via N-acetyltransferase, a enzyme dependent on B6, SAMe, and darkness. Glymphatic clearance removes beta-amyloid plaques during deep slow-wave sleep.
"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.

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.
