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.
The sleep supplement market is saturated with plausible-sounding products and inconsistent evidence. This guide applies the same rigorous evidence-quality framework to sleep supplements that NeuroEdge applies to cognitive compounds: human RCTs with specific sleep outcomes, mechanistic coherence, and honest caveats. Tier 1 (Magnesium Glycinate and Glycine — both with direct RCT evidence), Tier 2 (L-Theanine, Ashwagandha KSM-66, Magtein®), and what doesn’t make the list (Valerian, 5-HTP, CBD) — with the reasoning for each exclusion.
