Magnesium Glycinate for Sleep
Magnesium glycinate is the internet’s favourite sleep supplement — but does it work? The honest evidence, what the 2025 trial found, correct dosing, safety cautions, and who benefits most.
How to Get Better Sleep Tonight
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 Best Supplements for Sleep: What the Evidence Actually Shows
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.
Sleep Architecture: Understanding Sleep Stages and Cycles
Sleep has a structure, not just a duration. What happens across the stages and cycles of a night, why the shape isn’t symmetrical, what slow-wave sleep does for memory, and an honest look at the claims wearables and headlines get wrong.
Magnesium L-Threonate: Benefits, Dosage, and What the Research Actually Shows
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.
