What is behind Thyroid & Metabolism
Mitochondrial energy (ATP) output. Evidence A — Human trial evidence.
The cell's master energy sensor — when fuel runs low it ignites fat-burning, glucose uptake and mitochondrial renewal while standing down growth. Evidence A — Human trial evidence.
The transcription factor that commands the body's own antioxidant and detoxification arsenal. Evidence A — Human trial evidence.
The hypothalamic–pituitary–adrenal axis and its hormone cortisol — the body's central stress-and-recovery command. Evidence A — Human trial evidence.
Norepinephrine is the alertness and arousal neurotransmitter behind focus, drive and the stress response. Healthy tone supports attention, energy and mood. Evidence B — Preclinical.
Evidence on these pathways
AMPK → Insulin Sensitivity. “In model systems, sustained decreases in AMPK activity accompany IR, whereas AMPK activation increases insulin sensitivity.” — AMPK, insulin resistance, and the metabolic syndrome. The Journal of Clinical Investigation, 2013, volume 123, issue 7, pages 2764-2772. doi:10.1172/JCI67227
HPA Axis / Cortisol → Cognition. “Whereas treatments used in previous studies generally affect more than one memory phase and therefore cannot detect possible differential effects of glucocorticoids on the distinct phases of acquisition, consolidation and retrieval, here we show that treatment of healthy humans with cortisone at acute-stress levels specifically impaired retrieval of declarative long-term memory for a word list.” — Acute cortisone administration impairs retrieval of long-term declarative memory in humans. Nature Neuroscience, 2000, vol 3, pp 313-314. doi:10.1038/73873
HPA Axis / Cortisol → Digestive Function. “Reports have consistently established that central administration of CRF acts in the brain to inhibit gastric emptying while stimulating colonic motor function through modulation of the vagal and sacral parasympathetic outflow in rodents.” — Corticotropin-Releasing Factor and the Brain-Gut Motor Response to Stress. Canadian Journal of Gastroenterology, 1999, vol 13, pp 18A-25A. doi:10.1155/1999/375916
HPA Axis / Cortisol → Prolactin. “Stress is also an important physiologic cause of hyperprolactinemia, and its clinical significance is still being explored.” — Stress-Induced Hyperprolactinemia: Pathophysiology and Clinical Approach. Obstetrics and Gynecology International, 2018, volume 2018, article ID 9253083. doi:10.1155/2018/9253083

What this page does not claim
This page names the pathways involved and the published evidence on each. It does not claim that any formula treats, cures or prevents Thyroid & Metabolism. A pathway opens here only on graded, published evidence, under a standard fixed before the evidence was gathered, and every figure above carries its grade.
