Magnesium glycinate calms the nervous system at the receptor level

Magnesium ions potentiate GABA receptors, dampening neural excitability before sleep onset.

Anyone else struggling with sleep lately?

Tried everything: no screens, cold room, boring podcasts. Still wide awake at 3am most nights. What actually worked for you?

Magnesium helps you sleep. Glycinate specifically, it calms your nervous system down at the receptor level. Two weeks in and I am out before midnight.

Honestly the biggest thing for me was no screens. Blue light from screens wrecks your melatonin.

Weighted blanket. They lower cortisol, or at least mine did.

Magnesium potentiation of the function of native and recombinant GABA(A) receptors

T Möykkynen, M Uusi-Oukari, J Heikkilä, D M Lovinger, H Lüddens, E R Korpi

Neuroreport 12(10): 2175–2179 · 20 July 2001 · doi: 10.1097/00001756-200107200-00026

Abstract

Mg2+ decreased basal and GABA-inhibited t-butylbicyclophosphoro[35S]thionate binding to GABAA receptor ion channels in rat brain sections up to 1 mM, but increased the binding at 10 mM. The Mg2+-effect was detectable in the presence of a specific GABA site competitive antagonist. Two-electrode voltage clamp recordings of recombinant alpha1beta2gamma2S, alpha1beta2, alpha2beta2gamma2S and alpha2beta2 GABAA receptors revealed a potentiation by 0.1-1 mM Mg2+ of EC20 GABA-evoked ion currents. At 10 mM, Mg2+ decreased the currents. In the absence of GABA, Mg2+ did not evoke any currents. The results show that physiologically relevant Mg2+ concentrations affect the GABA responses on GABAA receptors in native and the main recombinant receptor subtypes, suggesting putative Mg2+ binding sites on the receptor complex.
