How do I choose adjunctive products for nervous system health?
Shelf order follows the badges: magnesium glycinate leads as the aisle's only guideline-endorsed member (AAN Level B for migraine prevention, plus the NMDA-gate excitability chemistry), alpha-lipoic acid carries the neuropathy indication's trial program (600 mg, honestly sized between IV strength and oral modesty), and the EPA-forward omega-3 delivers the membrane's structural fat with the mood-adjunct formulation lesson attached. All three sit behind the emergency rules, the workup discipline (glucose, B12, thyroid), and neurology's prescription tier — and none touches the B6-megadose trap the aisle sells beside them. The products below are educational examples — not medical recommendations.
Thorne Magnesium Bisglycinate
by Thorne · The Excitability Gate
Score
The only supplement on this page carrying a formal neurology guideline endorsement: the American Academy of Neurology rates magnesium 'probably effective' for migraine prevention (Level B) — the strongest formal badge in the entire nervous-system aisle. The mechanism behind the badge: magnesium gates the NMDA receptor — the system's master excitability switch — and its deficiency state (cramps, twitching, the anxious-wired pattern) is the gate left ajar. 🚨 350 mg/day supplemental ceiling (elemental); potentiates blood pressure medication; kidney disease = physician gate; glycinate the tolerated form (our magnesium page's ladder).
