Poor sleep is the most reliably documented impairment to cognitive performance available — and the most commonly ignored one. This guide covers the evidence-ranked sequence for tonight: environmental interventions first (largest, fastest, free), timing changes second, then supplementation — Magnesium Glycinate, Glycine, L-Theanine, and the pre-formulated Performance Lab Sleep option — all within the NeuroEdge 90-60-30 wind-down protocol.
Most people taking magnesium are taking the wrong form for cognitive purposes. Magnesium L-Threonate is the only commercially available magnesium compound with documented ability to meaningfully raise brain magnesium concentrations — addressing the NMDA receptor gating mechanism that determines synaptic plasticity efficiency. The Liu et al. trial reversed approximately 9 years of age-related cognitive decline in 12 weeks. This complete guide covers the mechanism, the MIT Neuron publication, the Magtein® quality distinction, and why evening timing is mechanistically optimal.
