Headaches: A Nutrition and Natural-Health Reference
1. Definition and Presentation
A headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck. Headache is an almost universal human experience and one of the most common complaints encountered in medicine and neurology. The most well-recognized classification system is that of the International Headache Society, which categorizes headaches into more than 150 types of primary and secondary headaches.
The International Classification of Headache Disorders (ICHD-3) broadly divides headaches into primary and secondary forms. The main types of primary headaches include tension-type headache, migraine, and cluster headache. Secondary headaches may arise from underlying conditions such as intracranial bleeding or infection.
Headaches manifest as pain or discomfort in the head, scalp, or neck and can be classified into several types, including migraines, tension-type headaches, and cluster headaches. Migraine specifically presents as a complex, episodic disorder. Migraine is characterized by recurrent attacks of moderate to severe head pain, typically affecting one side of the head, and accompanied by photophobia, phonophobia, and nausea. According to the 2018 ICHD-3, migraine is classified into two main types: migraine without aura, characterized by headaches with distinct features and related symptoms, and migraine with aura, mainly marked by temporary focal neurological symptoms that typically occur before or sometimes during the headache. Some individuals may also experience a prodromal phase, which occurs hours or days before the headache, and/or a postdromal phase after the headache subsides.
2. Body Systems and Anatomical Structures Involved
Under normal physiologic conditions, the brain is largely insensate. Head pain is mediated by projections from the trigeminal and upper cervical dorsal root ganglia, which innervate the pial, dural, and extracranial blood vessels. Head pain occurs when nociceptive neurons within the trigeminal, vagus, or glossopharyngeal cranial nerves or within the upper cervical roots become depolarized.
Key anatomical structures involved in headache pain are the large intracranial vessels, dura mater, trigeminal nerve, and pain modulatory brain systems. In general, these pseudounipolar neurons innervate the vessels on the same side, which can explain the unilateral distribution of pain in certain headache types, but some of the cells project bilaterally to innervate midline vessels.
The trigeminovascular system, which involves the trigeminal nerve and associated blood vessels, plays a key role in the pathophysiology of migraines. Cortical spreading depression (CSD) has been demonstrated to activate the trigeminovascular system both centrally and peripherally by exposing the dura to inflammatory molecules, indicating that susceptibility to CSD may contribute to the initiation of migraine attacks. The headache phase follows the prodromal or aura stages of a migraine, marked by the activation and sensitization of the trigeminovascular system and brainstem, leading to disrupted sensory processing and various neurological symptoms indicative of altered brain excitability.
Migraine pathophysiology can be viewed upon a background of a presumably genetically induced hypersensitivity of the brain to both internal and external homeostatic changes that can act as headache triggers. Evidence also indicates a direct association between phases of migraine attacks and calcitonin gene-related peptide (CGRP), mitochondrial disorders, monoaminergic pathway, disruption in brain energy metabolism, and higher serum levels of glutamate and homocysteine. Vascular headaches such as migraines are thought to involve abnormal function of the brain's blood vessels or vascular system; muscle contraction headaches appear to involve the tightening or tensing of facial and neck muscles; while traction and inflammatory headaches are symptoms of other disorders, ranging from brain tumor to stroke or sinus infection.
3. Contributing and Associated Factors
3.1 General Causes and Triggers
Causes of headaches may include dehydration; fatigue; sleep deprivation; stress; the effects of medications (overuse) and recreational drugs, including withdrawal; viral infections; loud noises; head injury; rapid ingestion of a very cold food or beverage; and dental or sinus issues such as sinusitis.
3.2 Dietary Triggers
Dietary triggers are commonly reported by patients with a variety of headaches, particularly those with migraines. The presence of any specific dietary trigger in migraine patients varies from 10 to 64% depending on study population and methodology. Some foods trigger headache within an hour while others develop within 12 hours post ingestion. Alcohol (especially red wine and beer), chocolate, caffeine, dairy products such as aged cheese, food preservatives with nitrates and nitrites, monosodium glutamate (MSG), and artificial sweeteners such as aspartame have all been studied as migraine triggers.
Many types of diet, dairy products such as cheese and milk, as well as chocolate, citrus fruits, nuts, ice cream, tomatoes, onions, alcoholic beverages, coffee, caffeine, monosodium glutamate, histamine, tyramine, phenylethylamine, nitrites, aspartame, sucralose, and gluten have been considered in the literature as triggers influencing migraine headaches.
The symptoms of phenylethylamine and tryptamine intoxication mirror those observed in tyramine intoxication, including headaches, migraines, and elevated blood pressure.
There are instances where a noticeable delay occurs between eating a trigger food and the onset of a migraine, which makes it much more difficult to determine whether or not a food actually contributes to the exacerbation of a migraine attack. While the pathophysiology of migraine is not completely understood, evidence suggests that dietary factors may play a role in several possible mechanisms. Diet may have an effect on the modulation of neuropeptides, neuroreceptors and ion channels, sympathetic nervous system and cerebral glucose metabolism, and/or by causing inflammation.
3.3 Alcohol
Alcohol (especially red wine) and high, irregular caffeine intake are frequently reported triggers. On average, patients reported that approximately 2.18 ± 1.3 standard glasses of red wine or 2.16 ± 1.9 glasses of vodka were sufficient to trigger a migraine attack. Excessive alcohol consumption can cause dehydration, hypoglycemia from low blood sugar levels after an overnight fast — a common headache trigger — and disrupt sleep patterns, leading to poor-quality sleep and resulting in morning headaches, especially common in migraine.
3.4 Caffeine
Caffeine has a dual effect; while moderate intake can alleviate headaches, excessive consumption or abrupt withdrawal can cause rebound headaches, particularly upon waking. About 50% of patients experience headaches during caffeine withdrawal, and higher daily caffeine intake is associated with more severe withdrawal headaches.
3.5 Meal Timing, Fasting, and Body Weight
A study identified in a systematic review showed that nighttime snacking and eating a late dinner could reduce the odds of headache. Although the data quality was generally low to medium, these studies suggest that maintaining steady glucose levels by eating more frequent, small meals and snacks could be a strategy that might prevent headaches triggered by fasting. Observational data and clinical studies suggest that dietary patterns, gut microbiota, specific nutrients, meal timing, and body weight may influence attack frequency, duration, and severity.
3.6 Sleep and Physical Activity
Low physical activity has been associated with higher prevalence of headaches. The association of pure migraine, pure tension-type headache, and coexistent headache with the level of leisure-related physical activity has been studied in population-based research. In studies of tension-type headache (TTH), the vast majority of individuals were inactive or minimally active, and moderate to weak positive correlations were found between headache frequency and severity and depression, anxiety, and stress scores.
3.7 Dehydration
Severe dehydration corresponds to a fluids deficit of 5% or more and leads to difficulties in concentration, headache, irritability, and sleeplessness. Dehydration is listed among the recognized contributing factors to headache onset.
4. Nutrients Studied in Relation to Headaches
4.1 Magnesium
Scientific Evidence:
A large body of literature suggests a relationship between magnesium deficiency and mild and moderate tension-type headaches and migraines. A number of double-blind randomized placebo-controlled trials have shown that magnesium is efficacious in relieving headaches and have led to the recommendation of oral magnesium for headache relief in several national and international guidelines.
A study found that low serum magnesium levels caused a 35-fold increase in the likelihood of acute headaches in migraine patients, suggesting that magnesium deficiency is an independent risk factor for the onset of migraines.
Accumulated evidence from case reports, case–control studies, observational studies, and randomized, placebo-controlled trials has shown the effectiveness of magnesium supplementation in alleviating migraine, both acutely and chronically. Mechanisms that may help explain these results include the potential link between magnesium deficit and spreading cortical depression, vascular changes, and oxidative stress.
A 2018 systematic review provides Grade C (possibly effective) evidence for prevention of migraine with magnesium. Prophylactic treatment of migraine by means of high levels of magnesium dicitrate (600 mg) appears to be a safe and cost-efficient strategy in clinical use.
Level I evidence supports the use of magnesium in the prevention and treatment of migraine headache, among other health conditions. According to a large body of literature, magnesium, with its relative lack of side effects, is particularly compelling for headache use in groups in which side effects are less well tolerated, such as children, pregnant women, and the elderly population.
Studies have revealed decreased levels of magnesium in the plasma and brain of migraine patients. A deficit of these nutrients could play a role in the pathophysiology of migraine.
4.2 Riboflavin (Vitamin B2)
Scientific Evidence:
Riboflavin (vitamin B2) can be recommended for migraine prevention in adults, though pediatric use is not proven. Adverse events are minimal. Overall, results of studies to date have found that riboflavin has similar efficacy to valproate for migraine prophylaxis but has a more tolerable side effect profile.
The American Headache Society (AHS)/American Academy of Neurology (AAN) 2012 Guidelines assessed efficacy for supplements for migraine prevention and provided riboflavin with Level B (probably effective) evidence.
The Canadian Headache Society Guideline for Migraine Prophylaxis includes riboflavin, coenzyme Q10, and magnesium citrate in the list of prophylactic agents that received a strong recommendation for use, alongside topiramate, propranolol, and amitriptyline.
Riboflavin, also known as vitamin B2, is an essential water-soluble vitamin found in animal-derived foods such as meat, dairy products, and eggs, as well as plant-based sources such as spinach, almonds, and quinoa. The mechanistic link to migraine centers on mitochondrial energy metabolism: supplementation with nutrients involved in mitochondrial function, brain energy metabolism, and methyl donors may relieve migraine attacks.
4.3 Coenzyme Q10 (CoQ10 / Ubiquinone)
Scientific Evidence:
Coenzyme Q10 has Level C evidence for migraine prevention and low adverse events. There is some limited evidence that coenzyme Q10 may help reduce the duration and frequency of migraines, but not their severity.
The AHS/AAN 2012 Guidelines classified CoQ10 as Level C (possibly effective) for migraine prevention. The mechanistic rationale parallels that for riboflavin: studies have revealed decreased levels of CoQ10 in plasma and brain of migraine patients, and a deficit of these nutrients could play a role in the pathophysiology of migraine.
4.4 Omega-3 Fatty Acids
Scientific Evidence:
Much evidence has shown a role of inflammation in the pathogenesis of migraine. Omega-3 fatty acids are important components of cell membrane phospholipids. Their intake is related to decreased concentrations of C-reactive protein, proinflammatory eicosanoids, cytokines, chemokines, and other inflammation biomarkers.
A systematic meta-analysis of omega-3 supplementation revealed a significant reduction in migraine frequency (MD: −1.74 days per month) and severity of migraine attacks.
A secondary analysis of a completed 3-arm randomized, controlled, dietary intervention trial found that a high omega-3 diet, with or without reductions in omega-6 linoleic acid intakes, decreased headache frequency, intensity, and duration.
However, evidence is not uniformly positive. A large two-by-two factorial design study over 4.6 years with 25,871 middle-aged or older adults, including 1,032 with a history of probable migraine, found that neither vitamin D nor marine omega-3 PUFAs supplementation affected migraine frequency or severity compared to a placebo. Diets high in omega-3 fatty acids may be helpful for migraines; however, omega-3s in supplement form have not been shown to reduce the frequency or severity of migraines consistently across all studies. The evidence from dietary omega-3 interventions is therefore more favorable than that from isolated supplementation alone, and the overall body of evidence must be characterized as preliminary to moderate.
4.5 Vitamin D
Scientific Evidence:
Vitamin D's active form, calcitriol, binds receptors implicated in neurodegenerative and neurological conditions, including migraines. Studies demonstrate a connection between vitamin D deficiency and increased migraine risk. However, as noted above, a large factorial design trial found that marine omega-3 PUFAs and vitamin D supplementation did not affect migraine frequency or severity compared to placebo. Overall, the evidence for vitamin D supplementation in headache management remains preliminary and inconsistent.
5. Herbs and Natural Ingredients
5.1 Feverfew (Tanacetum parthenium)
Traditional Use:
Feverfew (Tanacetum parthenium) is an herbaceous perennial native to Asia Minor and common in the Balkans, now naturalized throughout most of Europe, the Americas, and the rest of the world. It is a member of the Asteraceae family. The dried leaves or aerial parts are used for medicinal purposes. Traditionally it has been used for fever, women's ailments, inflammatory conditions, psoriasis, toothache, insect bites, rheumatism, asthma, and stomach-ache. Today feverfew extract is predominantly used for preventing migraine attacks and alleviating accompanying symptoms.
Scientific Evidence:
A Cochrane systematic review covering evidence up to January 2015 for or against feverfew in the prevention of migraine found six studies including 561 participants. Generally the studies were heterogeneous and their results were mixed. The previous version of this review showed no clear benefit of feverfew compared with placebo. A later, larger, higher-quality study added to the review showed that feverfew reduced migraine frequency by a little more than half a migraine (0.6) per month compared to placebo. There was no difference in how severe the pain was or how long it lasted. These results come from a single study of moderate size and must be viewed with caution until confirmed in other rigorous studies.
Feverfew suppresses serotonin-induced contractions in vascular smooth muscle and neutralizes sulfhydryl groups to inhibit platelet granule release. Feverfew extract also reduces histamine release from mast cells, possibly by modulating calcium influx. These combined effects contribute to its proposed role in migraine prophylaxis.
Feverfew may be effective for migraine prevention, but the absence of clear safety studies, the differences in doses and characteristics of dried leaf preparations, and the myriad of feverfew cellular effects suggest caution in its recommendation for use. The AHS/AAN guidelines classified feverfew as Level B (probably effective) for migraine prevention.
5.2 Butterbur (Petasites hybridus)
Traditional Use:
Butterbur has a history of use in European folk medicine as an antispasmodic agent. Its root extract has been used historically for pain, cough, and urinary tract complaints.
Scientific Evidence:
Butterbur appears to help reduce the frequency of migraines in adults and children. However, butterbur contains pyrrolizidine alkaloids (PAs), which are hepatotoxic. The American Academy of Neurology stopped recommending butterbur in 2015 because of serious concerns about possible liver toxicity. Based on two randomized controlled trials, butterbur was classified as having Level A evidence in the AHS/AAN 2012 guidelines; however, concerns over hepatotoxicity resulted in these entire guidelines being retired. Some butterbur preparations have had PA toxins removed to ensure safety; only butterbur products that have been processed to remove PAs and are labeled or certified as PA-free should be considered for use.
5.3 Ginger (Zingiber officinale)
Traditional Use:
Feverfew and ginger have both been traditionally used in folkloric medicine to treat headaches, arthritis, asthma, anxiety, various neurological disorders, and menstrual discomfort. Ginger (Zingiber officinale) has been used across Asian traditional medical systems including Ayurveda and Traditional Chinese Medicine for pain relief and nausea.
Scientific Evidence:
A meta-analysis of randomized controlled studies concluded that ginger is safe and effective in treating migraine patients for pain outcomes assessed at 2 hours. In vitro and animal studies demonstrated that many compounds of ginger possess antioxidative and anti-inflammatory activities that may be active in lowering chronic inflammatory disease symptoms, including pain. However, human studies assessing oral or topical ginger's positive effect on pain are not numerous, and different dosages, methods of administration, product formulations, and study designs were used across studies.
Previous studies have shown an analgesic effect of ginger in the acute treatment of migraine, and there is anecdotal evidence of its efficacy in migraine prophylaxis. Several natural products, including ginger, butterbur, turmeric, feverfew, and ginkgo, have shown promising potential for the management of migraine. Overall, evidence for ginger in migraine treatment is considered preliminary and encouraging, but trials are small and heterogeneous.
5.4 Peppermint (Mentha × piperita) Oil
Traditional Use:
Peppermint has been used in European herbal traditions as a topical and inhaled remedy for headache, as well as for digestive complaints, due to its menthol content.
Scientific Evidence:
A controlled study involving 41 patients with tension-type headache showed for the first time that a 10% peppermint oil in ethanol solution efficiently alleviates tension-type headache and proved to be a well-tolerated and cost-effective alternative to usual therapies. The study analyzed 164 headache attacks in a double-blind, randomized crossover design, with each headache attack treated by cutaneous application of the oil preparation. A 10% peppermint oil in ethanol solution significantly reduced clinical headache intensity already after 15 minutes compared to placebo (p < 0.01), and this reduction continued over the one-hour observation period. There was no significant difference between the efficacy of 1,000 mg acetaminophen and 10% peppermint oil in ethanol solution.
In clinical settings, peppermint oil diluted to 1.5% was applied to the nostrils during the onset of migraines; patients experienced relief within five minutes, with notable reductions in both headache intensity and frequency comparable to the lidocaine group. The rapid action of peppermint oil is largely attributed to menthol, a key compound that activates TRPM8 receptors, producing a cooling sensation that helps modulate pain and inflammation.
5.5 Melatonin
Scientific Evidence:
A randomized, multi-center, parallel-group clinical trial compared melatonin with amitriptyline and placebo for twelve weeks. A 3 mg dose of melatonin reduced migraine frequency, demonstrating the same effectiveness as amitriptyline in the primary endpoint of the frequency of migraine headaches per month. Melatonin was superior to amitriptyline in the percentage of patients with a greater than 50% reduction in migraine frequency, and melatonin was better tolerated than amitriptyline.
There is still a paucity of studies, and melatonin's effectiveness for migraine remains unclear with current limited literature. Current experimental evidence cannot claim a confirmed beneficial role of melatonin for migraine prophylaxis because placebo-controlled trials presented conflicting results — in some studies melatonin was superior to placebo, while in others it was not different from placebo. Melatonin has very low certainty for evidence of efficacy, and is weakly recommended in those with sleep problems.
6. Dietary Patterns and Lifestyle Factors
6.1 Dietary Patterns
Dietary interventions such as low-fat diet, low glycemic index diet, elimination diet, ketogenic diet, and the Dietary Approach to Stop Hypertension (DASH) diet have shown promising therapeutic benefits for migraine. Current evidence supports recommending Mediterranean-style eating, consideration of omega-3 supplementation, and selective trials of ketogenic or elimination approaches in appropriate patients, alongside weight management and lifestyle optimization.
A gluten-free diet has shown remarkable effectiveness in patients with celiac disease, significantly reducing the frequency of headaches and migraines. The role of dietary restriction in managing patients with migraines remains a contentious issue within the field of headache management.
Nutrition-related factors, such as the composition of one's diet and its quality, have been identified as potential triggers for migraine attacks or as contributing risk factors for the development of migraine. However, a recent systematic review has highlighted the need for high-quality studies to establish the diet-migraine association.
6.2 Weight and Obesity
Weight loss and regular physical activity may reduce headache burden in people with obesity. Body weight may influence attack frequency, duration, and severity.
6.3 Physical Activity
Multinomial logistic regression analysis in a population study demonstrated that primary headache was associated with low physical activity (OR=2.54, 95% CI=1.47–4.39, p=0.001) and medium physical activity (OR=1.62, 95% CI=1.05–2.52, p=0.03). In studies of TTH, longer headache duration and higher resting pain intensity were negatively correlated with RMSSD, an indicator of lower parasympathetic activity.
6.4 Sleep
Sleep deprivation is one of the recognized causes of headaches. Migraine headaches are comorbid with several health conditions, including neurological, psychiatric, cardiovascular, cerebrovascular, gastrointestinal, metaboloendocrine, and immunological disorders. The bidirectional relationship between sleep quality and headache frequency is recognized in the literature, with both poor sleep promoting headaches and frequent headaches disrupting sleep architecture.
6.5 Gut Microbiome and Emerging Areas
Investigating how the brain interacts with diet and the gut microbiome in relation to migraines is an interesting and active subject for further research. Evidence indicates that supplementation with riboflavin, omega-3 fatty acids, alpha-lipoic acid, magnesium, probiotics, coenzyme Q10, ginger, and caffeine may have favorable effects on migraine patients. High-quality, longer-duration RCTs using standardized dietary protocols and adherence biomarkers are needed to define dose–response relationships and enable personalized nutrition in migraine.
