    Magnesium for Panic Attack Prevention

    Magnesium has small anxiolytic effects that may reduce background arousal, but no panic-specific evidence.

    Overview

    Magnesium has small anxiolytic effects that may reduce background arousal, but no panic-specific evidence.

    Verdict

    Mixed evidence

    How It Works

    As an NMDA antagonist and GABA modulator, magnesium reduces neuronal excitability and blunts the HPA stress response.

    Dosing & Protocol

    Typical dose

    Recommended dose
    200-400mg elemental magnesium (glycinate) daily
    Expected timeframe
    4 weeks

    Protocol

    form
    Magnesium glycinate or citrate
    duration
    6-8 weeks
    co factor
    Take with food. Evidence is mixed and does not extend to panic specifically. Randomised trials and meta-analyses support a modest reduction in anxiety and depressive symptoms with magnesium, most clearly in people with low magnesium status, and the mechanism is coherent - GABA-A positive modulation, NMDA receptor antagonism and dampened HPA axis reactivity, with magnesium deficiency in animal models producing anxiety-like behaviour. But no trial has examined panic attacks or panic disorder. Oral magnesium also acts over weeks rather than minutes, so it cannot abort an attack, which typically peaks within ten minutes. Reducing baseline anxiety might plausibly reduce attack frequency, but this remains untested.
    titration
    Up to 400 mg/day in divided doses
    starting dose
    200 mg elemental magnesium daily with food, if using it for general anxiety

    Evidence

    What the studies say

    Meta-analyses report modest anxiety reductions, strongest in people with low intake or high stress. No trial has used panic attack frequency as an endpoint.

    Existing evidence is suggestive of a beneficial effect of Mg on subjective anxiety in anxiety vulnerable samples. However, the quality of the existing evidence is poor.

    Safety

    Caveats

    Adjunct only. Reduce dose in kidney impairment.

    Less likely to help if

    People with panic disorder needing proper treatment, and anyone seeking acute relief during an attack.
