Magnesium for Back Pain Relief
Magnesium influences muscle relaxation and NMDA-receptor-mediated pain sensitization. Evidence for chronic low back pain specifically is limited to small studies, but it is low-risk and often deficient in modern diets.
Overview
Verdict
Plausible role in muscle tension and neuropathic components; direct back-pain RCT evidence is thin.
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- 200–400 mg magnesium glycinate or citrate in the evening.
- Expected timeframe
- 4–8 weeks.
Protocol
- form
- Magnesium glycinate for tolerability; citrate if constipation coexists
- duration
- 4-6 weeks to judge
- co factor
- Take with food. Evidence is mixed and thinner than commonly claimed. The most cited trial used a two-week intravenous magnesium infusion followed by four weeks of oral magnesium in patients with chronic low back pain and a neuropathic component, and found reduced pain intensity - but the intravenous phase makes it a poor guide to what an oral supplement alone achieves. Mechanistically magnesium is an NMDA receptor antagonist, which is relevant to central sensitisation and neuropathic pain, and it reduces muscle excitability, which may help spasm-related pain. For mechanical, non-neuropathic back pain, which is most back pain, evidence is essentially absent.
- titration
- Up to 400 mg/day in divided doses; reduce if stools loosen
- starting dose
- 200 mg elemental magnesium daily with food
Evidence
No studies are yet linked to both Magnesium and Back Pain Relief.
Safety
Caveats
Loose stools at higher doses (citrate > glycinate). Caution with kidney disease.
