Without copper delivered in this controlled manner, these enzymatic processes slow down

Proposed Mechanisms Preventing GABA receptor downregulation Counteracting compensatory NMDA glutamate receptor sensitization Stabilizing benzodiazepine receptor configuration (preventing shift to inverse agonist state) Upregulating GABAergic neurotransmission through pathways distinct from benzodiazepine action itself This tolerance prevention has profound clinical implications

The choice should be guided by the model and the endpoint, not by marketing

Limitations to Consider: The absorption variability creates uncertainty about whether youre receiving therapeutic doses
