Vitamin D and Headaches
Beyond the well-studied migraine evidence, vitamin D has been examined in tension-type headaches, cluster headaches, and other headache disorders. Deficiency is more common in chronic headache patients than in controls, but the specific-headache-type evidence for supplementation benefit is more limited than for migraine.
Tension-type headaches
The most common headache type — pressing, bilateral, mild-to-moderate. Chronic tension-type headache patients have lower mean 25(OH)D than controls in several studies. Prakash 2010 reported symptom improvement with high-dose vitamin D + calcium in patients with deficiency-related bone pain and headache. Standard first-line management is stress reduction, sleep, hydration, and NSAIDs; vitamin D is an adjunct in the deficient.
Cluster headaches
Severe unilateral orbital pain, autonomic features, cyclical. Case series have reported cluster headache improvement with high-dose vitamin D supplementation, most notably by Peter Goadsby's group observing seasonal cluster patterns. The Northwestern "vitamin D3 anti-inflammatory protocol" (Batcheller et al.) uses cholecalciferol 10,000 IU/day plus cofactors; small series suggests reduction in attack frequency in some patients. Trial-level evidence is lacking; work with a headache specialist if considering high-dose regimens.
Cervicogenic headaches
Headache from cervical spine dysfunction. Chronic musculoskeletal pain populations (of which this is one) show benefit from vitamin D correction in deficient patients; specific cervicogenic trials are limited.

Practical guide
- Frequent or chronic headache patients: test 25(OH)D.
- Correct deficiency to ≥ 30 ng/mL with standard dosing.
- Continue evidence-based headache management (identifying triggers, appropriate acute and preventive medication).
- Red-flag headaches (thunderclap, associated neurology, new after 50, worsening pattern) need urgent evaluation — not a vitamin trial.
