Magnesium for Tension Headaches: Mechanics First
The everyday band-of-pressure headache is mechanical — posture, screens, hydration, sleep — which makes its fix list mechanical too. The honest guide: what moves it, the painkiller-counting trap, and the mineral's floor-layer place.
At a glance
- Tension-type = the band of pressure: driven by posture, screens, dehydration, stress, sleep
- Magnesium's evidence home is migraine prevention — a different condition with its own article
- The trap to know: medication-overuse headache — painkiller days climbing is itself the problem
- Red flags: thunderclap, neurological symptoms, new pattern 50+ → urgent/GP
The headache most people actually have, decoded
The tension-type headache — bilateral, pressing, the too-tight-hatband feeling — is the everyday headache of desk-lit lives, and its driver list is refreshingly mechanical: neck and shoulder muscles held tense for hours, screens at the wrong height, jaws quietly clenched (that habit's own article), dehydration, stress load and short sleep. Distinguishing it from migraine matters because the plans diverge: migraine's one-sided, pulsating, nausea-and-light-sensitivity signature has its own prevention conversation — where magnesium holds genuine research standing at GP-supervised doses (that evidence, told straight). This page handles the band; that page handles the storm.
The fix list, ranked by how much it actually moves
Because the drivers are mechanical, so are the wins: hydration first (the cheapest headache intervention in existence — many band-headaches are the afternoon bill for a coffee-only morning); the desk audit second — screen top at eye height, shoulders down, the 45-minute movement snack (the full desk protocol); heat on the neck and simple stretching for the acute episode; sleep regularity underneath everything; and caffeine handled with awareness — both a trigger when stacked and a withdrawal headache when skipped, so consistency beats quantity. Simple painkillers used occasionally are fine and effective; the counting rule is the one to know — climbing painkiller days is the medication-overuse trap, and unwinding it with a GP is one of headache medicine's most reliably good outcomes.
Where the mineral honestly fits, and when to escalate
Magnesium's slot here is the familiar floor: authorised claims covering the exact machinery — normal muscle function for the tension, normal functioning of the nervous system, psychological function for the stress load — with the UK intake gap making the 300mg elemental serving a rational base under the mechanical fixes rather than a headache treatment over them. Futuro Labs Magnesium Glycinate holds the slot at 22p an evening (delayed-release vegan capsules, £19.99 across 90 days), pulling double duty through the sleep route most headache-prone weeks need anyway. Escalation lines, stated plainly: a sudden worst-ever thunderclap headache is 999; headaches with weakness, speech or vision disturbance, fever-and-stiff-neck, or after a head injury are urgent; and a new or changing headache pattern past 50, or headaches waking you from sleep, earn a prompt GP visit. The everyday band earns the fix list; anything outside it earns assessment.

The headache diary: two weeks that outperform most purchases
One tool deserves its own recommendation because it upgrades every other decision on this page: a two-week headache diary — date, time of onset, what the morning and afternoon held (screens, hydration, caffeine timing, sleep the night before), and painkiller use. Patterns surface embarrassingly fast: the Tuesday-Wednesday cluster that maps to the office's worst desk, the 4pm onset that tracks a coffee-only morning, the painkiller days quietly climbing toward the overuse threshold. The diary also transforms any GP visit from vague complaint to solvable pattern, and it costs nothing. Most band-headache careers end not with a product but with one identified driver, removed.
Frequently asked questions
Does magnesium help tension headaches?
The tension-type headache — the band-of-pressure kind — answers mainly to its drivers: neck-and-shoulder tension, screen posture, dehydration, stress, disrupted sleep and painkiller overuse. Magnesium's serious research tradition is in migraine prevention, a different condition; for tension headaches its role is the general base layer (muscle-function and nervous-system claims) under the mechanical fixes, not a treatment.
How do I tell tension headache from migraine?
Rough guide: tension-type is a bilateral, pressing, band-like ache — annoying but usually functional through it; migraine is more often one-sided, pulsating, moderate-to-severe, worsened by activity, and travels with nausea or light-and-sound sensitivity, sometimes aura. The distinction matters because migraine has its own prevention conversation — including magnesium's real evidence there — via your GP.
What is medication-overuse headache?
The trap where the fix becomes the cause: taking painkillers for headaches on many days a month (roughly 15+ for simple painkillers, 10+ for combination or triptan products) can itself sustain near-daily headache. If your painkiller days are climbing, that's a GP conversation with a genuinely good outcome — withdrawal under guidance typically resolves it.
