Prevention raises the threshold.
MIGRAINES, EXPLAINED
Migraine attacks can become more likely when several factors add up. A good plan lowers avoidable strain and builds consistency across the day.
It is rarely just one trigger.
THINK OF A THRESHOLD
Poor sleep, missed meals, dehydration, stress, hormonal changes and other factors can accumulate. Some cannot be controlled. The goal is not perfect avoidance—it is to make the modifiable pieces more stable.

| MIGRAINE THRESHOLD |
Regular sleep
A consistent schedule matters more than chasing a perfect number every night.
Meals and hydration
Avoid long fasting periods. Hydrate regularly and eat in a way you can sustain.
Movement
Build toward consistent aerobic activity while respecting your current capacity.
Trigger awareness
Use a diary to notice patterns. Broad, restrictive elimination diets are rarely the best starting point.
Acute treatment
Treat attacks as directed, and discuss frequent acute medication use with your clinician.
Preventive treatment
Daily strategies need time. Review benefit, tolerability and next steps with your healthcare professional.
Understanding Migraine and Its Impact
Migraine is a neurological disorder characterized by recurrent attacks of headache and associated neurological symptoms. A typical migraine headache lasts 4 to 72 hours when untreated and usually has at least two of the following features: one-sided location, pulsating or throbbing quality, moderate to severe intensity, or worsening with routine physical activity. During the headache, there is typically nausea and/or vomiting, or sensitivity to both light and sound (photophobia and phonophobia).
A diagnosis of migraine without aura generally requires a history of at least five attacks meeting these criteria and not being better explained by another headache disorder. Some people also experience migraine with aura, consisting of temporary neurological symptoms—most commonly visual, but sometimes sensory or language symptoms—that typically develop gradually and resolve completely.
The headache phase of an untreated migraine attack typically lasts approximately 4 to 72 hours, although individual experiences vary.
Migraine may involve several phases. A prodrome can occur before the headache and may include fatigue, mood changes, food cravings or difficulty concentrating. Some people experience aura, which consists of temporary neurological symptoms such as visual disturbances, sensory symptoms or language difficulties.
The headache phase may then be followed by a postdrome, during which fatigue, cognitive slowing or a general feeling of being unwell can persist even after the headache has resolved.
Not everyone experiences every phase.
Migraine is commonly classified as either episodic or chronic, based largely on the number of headache days a person experiences each month.
Episodic migraine refers to migraine in someone who experiences fewer than 15 headache days per month. The frequency can vary considerably, from an occasional migraine attack to headaches occurring many days each month.
Chronic migraine is defined as having 15 or more headache days per month for more than 3 months in a person with a history of migraine. At least 8 days per month must have features of migraine, be recognized by the patient as migraine and relieved by a migraine-specific medication such as a triptan or ergot, or otherwise meet established criteria for migraine with or without aura.
Importantly, the other headache days do not all need to feel like a typical severe migraine. People with chronic migraine may have a background of milder daily or near-daily headache, with more severe migraine attacks occurring on top of it. Symptoms such as light sensitivity, sound sensitivity, nausea, cognitive fog and sensitivity to smells may also persist between more severe attacks.
Migraine frequency can change over time. Episodic migraine can progress to chronic migraine, a process sometimes called chronification, while effective treatment and management of contributing factors can reduce headache frequency and allow chronic migraine to return to an episodic pattern.
Keeping track of all headache days—not just the most severe migraine days—is important when determining whether migraine is episodic or chronic.
Nausea can be a symptom of migraine, and vomiting can occur during more severe attacks.
These symptoms reflect the widespread neurological effects of migraine rather than simply being a reaction to headache pain. Migraine may also produce sensitivity to movement, light, sound and smells, all of which can worsen nausea during an attack.
Very commonly. Photophobia, or sensitivity to light, and phonophobia, or sensitivity to sound, are characteristic features of migraine. Some people also develop osmophobia, an increased sensitivity to smells.
During an attack, ordinary levels of light, noise or smell may become uncomfortable or even intolerable. This sensory hypersensitivity reflects altered processing of sensory information within the nervous system during migraine.
Importantly, these sensitivities do not always disappear completely between attacks. In people with chronic migraine, particularly those with frequent or daily headaches, photophobia and other forms of sensory hypersensitivity may persist on a daily or near-daily basis. Some people therefore experience constant sensitivity to bright lights, screens, glare, loud environments or strong smells even when they are not experiencing a severe migraine attack.
Absolutely! Cognitive symptoms are common during migraine attacks and may occur before or after the headache phase.
People may describe difficulty concentrating, slowed thinking, mental fatigue, impaired attention or difficulty finding words. This is sometimes informally described as “brain fog.”
These symptoms do not necessarily indicate a primary memory disorder. Rather, they can form part of the neurological symptoms associated with a migraine attack.
Sleep and migraine are very intertwined. The relationship between migraine and sleep is bidirectional: sleep disruption can increase susceptibility to migraine, while migraine can interfere with sleep.
Insomnia, irregular sleep schedules, insufficient sleep and sometimes excessive sleep can be associated with attacks. Maintaining regular sleep and wake times is therefore an important component of migraine management.
Persistent sleep difficulties or symptoms suggestive of a sleep disorder should be discussed with a healthcare professional.
Yes. Migraine is associated with an increased prevalence of anxiety and depression, and mood symptoms can also fluctuate around individual attacks.
Some people experience irritability, anxiety, low mood or changes in energy before, during or after migraine episodes.
Persistent anxiety or depressive symptoms should not simply be attributed to migraine and should be discussed with a healthcare professional, as both conditions can be treated.
Physical activity can aggravate headache during an active migraine attack, which is one of the characteristic clinical features of migraine.
Outside of an attack, however, regular physical activity is generally encouraged. Consistent aerobic exercise may contribute to overall migraine management as well as cardiovascular health, sleep quality and stress reduction.
Exercise should be introduced gradually and combined with appropriate hydration and nutrition.
Migraine is much more than a headache. It is a neurological disorder that can cause a headache that is often pulsatile, nausea, vomiting, sensitivity to light and sound, cognitive symptoms, fatigue and other neurological symptoms.
An attack may interfere substantially with work, school, parenting, relationships, exercise and social activities. Some people need to stop normal activities and rest in a dark, quiet environment until symptoms improve.
The disability associated with migraine can also extend beyond the attack itself because people may alter their plans or activities out of concern about when the next attack will occur.
100%. Migraine can significantly impair occupational functioning.
Throbbing headache, photophobia, phonophobia, nausea, visual symptoms and cognitive difficulties can make computer work, reading, driving, communicating and concentrating difficult.
Migraine can therefore result in both absenteeism, meaning missed work, and presenteeism, meaning being at work but functioning below normal capacity.
For people with frequent migraine, this can create a substantial cumulative burden. Some people are forced to leave work and pursue disability benefits.
Migraine can have a substantial social impact.
The unpredictable nature of attacks may result in cancelled plans, missed family activities or avoidance of situations in which an attack would be particularly difficult to manage. Family members and friends may also have difficulty understanding the severity of a disorder that often has no visible external signs.
Effective prevention aims not only to reduce headache frequency but also to reduce the overall disruption migraine causes in everyday life.
Without a doubt. Migraine can substantially affect quality of life through its effects on work, family responsibilities, relationships, sleep, physical activity and emotional well-being.
For this reason, successful migraine prevention is not measured only by the number of headache days. Treatment may also aim to reduce attack severity and duration, improve response to acute treatment, reduce disability and allow people to participate more consistently in normal activities.
Especially if left untreated or undertreated. Some people with episodic migraine eventually develop chronic migraine, defined clinically by headache occurring on 15 or more days per month for more than three months, with migraine features present on at least eight days per month.
Several factors may contribute to increasing headache frequency, including ineffective acute or preventive treatment, sleep disturbance, stress, obesity and excessive use of certain acute headache medications.
Frequent use of acute medications can contribute to medication-overuse headache in susceptible individuals.
A meaningful increase in headache frequency or a substantial change in headache pattern should be discussed with a healthcare professional.
You have questions? We have answers! Causes, Impacts and Treatments for Migraines
(Click to enlarge)
Migraine is a complex neurological disorder involving genetic susceptibility and altered excitability of the brain and trigeminovascular system. During a migraine attack, activation of pain-processing pathways and release of neuropeptides such as calcitonin gene-related peptide (CGRP) contribute to headache and associated symptoms.
There is no single cause of migraine. Genetics, hormonal fluctuations, sleep disruption, stress, dehydration, missed meals, environmental stimuli and other factors can influence the threshold at which an attack occurs. Rather than being the underlying cause of migraine, these factors often act as triggers in a nervous system that is already susceptible to migraine.
Stress does not cause the underlying neurological disorder, but it is a commonly reported migraine trigger. Both periods of increased stress and the reduction in stress that follows a stressful period can be associated with attacks.
Stress can influence sleep, muscle tension, autonomic function and pain-processing pathways, potentially lowering the threshold for a migraine attack. Regular exercise, adequate sleep, relaxation techniques, mindfulness and other stress-management strategies may be helpful components of a comprehensive migraine prevention plan.
Sleep deprivation is one of the biggest, if not the biggest, triggers for migraine. Insufficient sleep, excessive sleep, poor-quality sleep and irregular sleep schedules may all increase susceptibility to migraine attacks in some individuals.
The migraine brain appears particularly sensitive to changes in routine. Maintaining consistent sleep and wake times, including on weekends when possible, can therefore be an important component of migraine prevention.
Sleep disorders such as insomnia and obstructive sleep apnea may also contribute to headache burden and should be assessed when clinically appropriate.
Here lie two other major migraine triggers. Dehydration is a well-known trigger; in fact, patients are often rehydrated in the emergency department as part of the treatment of severe migraine attacks and status migrainosus, particularly when dehydration is present. Maintaining normal hydration throughout the day, primarily with water, while avoiding excessive amounts of caffeine or sugar, can therefore be an important part of migraine prevention.
Fasting can also contribute to triggering a migraine by lowering the migraine threshold. Skipping meals, going prolonged periods without eating, or intermittent fasting can therefore be problematic for some people with migraine.
Triggers can also have a cumulative effect. For example, dehydration combined with poor sleep, stress and a missed meal may be more likely to precipitate an attack than any one factor alone.
Fluctuations in hormones, particularly estrogen, can significantly influence migraine susceptibility. Some women experience migraine attacks around menstruation, when estrogen levels fall.
Migraine patterns can also change considerably during pregnancy and postpartum. For many women, particularly those with migraine without aura, migraine attacks improve during the second and third trimesters as estrogen levels become higher and more stable. Migraine with aura may behave less predictably and, in some women, aura may occur for the first time during pregnancy. After delivery, the rapid fall in estrogen levels, combined with sleep disruption, stress and changes in routine, can lead to the recurrence or worsening of migraine during the postpartum period.
New, unusually severe or significantly different headaches during pregnancy or postpartum should not automatically be attributed to migraine and warrant medical assessment, as secondary causes of headache are more important to consider during these periods.
Migraine patterns may also change during perimenopause and menopause. Tracking migraine attacks alongside the menstrual cycle can help identify a hormonal pattern and may assist a healthcare professional in developing an appropriate treatment strategy.
An important consideration is migraine with aura. Migraine with aura is independently associated with an increased risk of ischemic stroke. Because estrogen-containing combined hormonal contraceptives can further increase this risk, they are generally contraindicated in women with migraine with aura.
Menopausal hormone therapy is somewhat different and requires an individualized assessment. Migraine with aura does not necessarily preclude menopausal hormone therapy, and when estrogen is required, lower-dose transdermal preparations are often preferred because they provide more stable estrogen levels and are associated with a lower thrombotic risk than oral estrogen. These options should be discussed with a healthcare professional based on the individual’s migraine pattern and other vascular risk factors.
Yes, although migraine triggers vary considerably from person to person and there is no single “migraine diet” that everyone needs to follow. In fact, many foods traditionally blamed for migraine have limited or conflicting scientific evidence behind them. Rather than unnecessarily eliminating large numbers of foods, it is generally more useful to identify your own reproducible triggers.
Commonly reported dietary triggers include alcohol, particularly red wine and beer; excessive caffeine or caffeine withdrawal; aspartame and some other artificial sweeteners; monosodium glutamate (MSG); processed or cured meats containing nitrates or nitrites, such as salami, bacon, ham and some sausages; aged or fermented foods, including some aged cheeses; foods high in tyramine or histamine; chocolate; some nuts and legumes, including peanuts; and citrus fruits in some individuals.
Food additives and artificial colours, including red food dyes, are sometimes reported by patients as triggers, but there is currently limited evidence that specific food dyes are consistent migraine triggers.
Smells can be important triggers as well. People with migraine can be particularly sensitive to strong odors, sometimes referred to as osmophobia. Perfume and cologne, cigarette smoke, gasoline or fuel fumes, scented detergents, cleaning products, air fresheners, paint and other strong chemical odors can precipitate or worsen an attack in susceptible individuals.
It is also important to remember that a suspected trigger may not cause an attack every time. Migraine is often a threshold disorder: a particular food or smell may cause no problem on one day but contribute to an attack when combined with other factors such as poor sleep, dehydration, stress, hormonal changes or a missed meal.
Keeping a migraine diary can help identify patterns. A food or environmental exposure is much more convincing as a personal trigger if migraine attacks repeatedly occur after that same exposure.
Treatments
Migraine treatment generally has two major components: acute treatment and preventive treatment.
Acute treatments are taken during an attack to reduce pain and associated symptoms. Depending on the individual, these may include anti-inflammatory medications, triptans, CGRP receptor antagonists known as gepants, anti-nausea medications and other non-pharmacological treatments such as cooling caps and peppermint rollers.
Preventive treatments are used to reduce the frequency, severity and disability associated with future attacks. Options can include evidence-based supplements such as Migraine Rx™, oral prescription medications, CGRP-targeted therapies, onabotulinumtoxinA (Botox) for chronic migraine and lifestyle interventions.
Treatment should be individualized according to migraine frequency, severity, associated symptoms, medical history and previous treatment response.
Migraine cannot always be completely prevented, but the frequency and severity of attacks can often be reduced substantially.
A comprehensive prevention strategy may include consistent sleep, regular meals, adequate hydration, exercise, stress management and appropriate preventive therapies.
For people with frequent or disabling attacks, preventive medication or other migraine-specific therapies may be appropriate. The objective is not necessarily to eliminate every migraine attack, but to reduce migraine burden and improve function and quality of life.
Medication-overuse headache, sometimes called a “rebound headache,” can occur in people with an underlying headache disorder who use acute headache medications too frequently over a prolonged period.
This can create a frustrating cycle. Headaches become more frequent, which leads to more frequent use of acute medication, and excessive use of certain medications can then contribute to maintaining or worsening the headache disorder.
Medication-overuse headache is generally considered when a person with a pre-existing headache disorder has headaches on 15 or more days per month and has been regularly overusing one or more acute headache medications for more than three months.
The amount of medication use that constitutes overuse depends on the medication. Triptans, opioids and combination analgesics used on 10 or more days per month can contribute to medication-overuse headache, while acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) used on 15 or more days per month can also contribute when this pattern continues for more than three months.
This does not mean that acute medications should be avoided. They are an important part of migraine treatment. The concern is frequent and repeated use over time, particularly in someone whose headaches have become increasingly frequent.
If you are regularly requiring acute migraine medication several days per week, this should be discussed with a healthcare professional. Optimizing preventive treatment and developing an appropriate acute-treatment strategy can help reduce medication overuse.
Keeping a migraine diary that records both headache days and acute medication days can be particularly helpful.
Several nutritional supplements, often referred to as nutraceuticals, have been studied for migraine prevention. Among the most established are magnesium, riboflavin (vitamin B2) and coenzyme Q10 (CoQ10). These nutrients have been included in migraine-prevention guidelines and have clinical evidence suggesting that they may reduce migraine frequency or severity in some individuals.
Their proposed mechanisms are particularly interesting because they target biological processes thought to be involved in migraine. Magnesium is important for neuronal excitability, neurotransmitter release and normal nerve and muscle function, and may influence several pathways involved in migraine. Riboflavin is essential for mitochondrial energy metabolism, while CoQ10 is an important component of the mitochondrial electron transport chain and cellular energy production. Abnormalities in cerebral energy metabolism and mitochondrial function have long been investigated as potential contributors to migraine susceptibility.
Vitamin D is another promising area of migraine research. Vitamin D does considerably more than regulate calcium and bone health. Vitamin D receptors are widely distributed throughout the body, including within the nervous and immune systems, and vitamin D has roles in immune regulation, inflammation, neuronal function and pain processing. Vitamin D deficiency has been reported more frequently in some populations with migraine and has been associated in several studies with greater headache frequency.
More importantly, evidence is beginning to extend beyond this association. Randomized controlled trials and subsequent meta-analyses have found that vitamin D supplementation may reduce the number of migraine attacks or headache days per month, although results for attack severity and duration have been less consistent. The evidence is newer and not yet as established in migraine guidelines as that for magnesium or riboflavin, and additional high-quality studies are still needed.
Nutraceuticals can therefore form one component of an overall migraine-prevention strategy alongside adequate sleep, hydration, regular meals, exercise, trigger management and, when appropriate, prescription preventive treatments. They are not a substitute for medical assessment when migraine is frequent, severe, changing in character or associated with concerning neurological symptoms.
Migraine Rx™ AM & PM, developed by Neuroceuticals, is a two-part daily formulation designed around evidence-based nutrients used in migraine prevention. Rather than placing every ingredient into a single formulation, Migraine Rx™ separates its ingredients into morning and evening formulas based on how they fit into a daily routine. Importantly, the formulation was designed around the doses used in migraine prevention—not simply the presence of each ingredient.
Migraine Rx™ AM — CoQ10 + Vitamin D
The morning formula contains coenzyme Q10 (CoQ10) 300 mg and vitamin D. CoQ10 plays an important role in mitochondrial energy production and has been studied for migraine prevention. The 300 mg daily dose provides CoQ10 at the upper end of commonly studied and recommended doses for migraine prevention. It is taken earlier in the day because some people find CoQ10 stimulating or experience sleep disruption when it is taken later in the evening.
Vitamin D is an emerging area of migraine research, with a growing body of clinical evidence suggesting a potential role in migraine prevention. Migraine Rx™ is the only migraine supplement in Canada formulated with vitamin D, bringing this emerging area of migraine research into a comprehensive daily formulation.
Migraine Rx™ PM — Magnesium + Riboflavin (Vitamin B2)
The evening formula contains 400 mg of elemental magnesium and 400 mg of riboflavin (vitamin B2). These are not token amounts added simply to appear on an ingredient list. Both are provided at substantial doses consistent with those commonly studied and recommended for migraine prevention. Riboflavin 400 mg daily is one of the best-established nutraceutical doses used in migraine prevention, while 400 mg of elemental magnesium provides a clinically meaningful preventive dose.
Magnesium is involved in neuronal excitability, neurotransmission and normal neuromuscular function, while riboflavin supports mitochondrial energy metabolism and has been studied extensively for migraine prevention. Because magnesium may also promote relaxation in some individuals, it is placed in the evening formulation rather than the morning formulation.
Not all forms of magnesium have been studied equally for migraine prevention. Migraine Rx™ PM uses magnesium citrate together with magnesium oxide to provide 400 mg of elemental magnesium while maintaining a practical capsule size.
Magnesium citrate was specifically selected because it is well absorbed and, importantly, is one of the forms of magnesium directly studied in clinical trials for migraine prevention and specifically referenced in migraine treatment guidelines. Other forms, such as magnesium glycinate or bisglycinate, are also well absorbed and may offer good gastrointestinal tolerability, but currently have considerably less direct clinical evidence specifically for migraine prevention.
Magnesium oxide provides a higher concentration of elemental magnesium, allowing this substantial dose to be delivered without requiring an impractical number of capsules.
Migraine prevention is not simply about choosing the right ingredients. The dose and timing matter too. Migraine Rx™ AM & PM was designed around three of the most established nutraceuticals used in migraine prevention—CoQ10 300 mg, magnesium 400 mg and riboflavin 400 mg—at doses consistent with the upper range of those commonly studied or recommended for migraine prevention.
The potential effects of the individual ingredients were also considered rather than simply combining everything into one formulation. CoQ10 is placed in the morning, when its potentially stimulating effects are less likely to interfere with sleep, while magnesium is placed in the evening, allowing its potential relaxing properties to work with rather than against the daily routine. Separating the formulations also creates a structured morning-and-evening routine that can make consistent daily use easier.
We don’t just consider which ingredients to use—we consider the dose and when to use them.

Migraine Rx™ was developed by me, a Canadian neurologist who regularly treats patients living with migraine. The formulation combines evidence from migraine research with practical considerations encountered in clinical migraine care.
MORE THAN THE RIGHT INGREDIENTS. THE RIGHT DOSE. THE RIGHT TIME.
Migraine Rx™ AM + PM — Evidence-based migraine prevention. Thoughtfully formulated.
Migraine Rx™ should be used according to the directions and recommended conditions of use on the product label.
Migraine Rx™ AM & PM can form one component of a broader migraine prevention strategy.
A comprehensive approach may also include consistent sleep and wake times, regular meals, adequate hydration, regular physical activity, stress management, identification of meaningful triggers and appropriate acute or prescription preventive treatments when required.
Migraine prevention is generally most effective when multiple modifiable factors are addressed rather than relying on a single intervention.
Preventive strategies generally require consistency and time.
Unlike acute medications, which are intended to treat an individual attack, preventive treatments are designed to reduce future migraine burden. The effect therefore needs to be evaluated over weeks to months rather than after a single dose.
For nutritional migraine prevention strategies, consistent daily use over an adequate trial period is important before determining whether they are beneficial.
Keep a migraine diary recording headache days, migraine days, severity and acute medication use. This provides a more objective way to determine whether a preventive strategy is working.
Using both formulas is the intended routine, but it isn’t all-or-nothing. If you don’t tolerate one formula, already obtain one of these nutrients elsewhere, or simply prefer to use only the AM or PM product, *each formula can also be used independently according to its directions.* The goal is to make evidence-based migraine prevention easier to incorporate into a routine that works for you.
Migraine Red Flags
Most headaches in people with an established history of migraine will be related to their underlying migraine disorder. However, new or substantially changed headaches should not automatically be assumed to be migraine.
A sudden, severe headache that reaches maximum intensity within seconds to a minute, sometimes referred to as a thunderclap headache, requires urgent medical assessment. This is particularly important when the headache is new or unlike anything previously experienced.
A new headache associated with weakness, numbness, difficulty speaking, confusion, loss of consciousness, a seizure or other significant neurological symptoms also requires prompt medical assessment, particularly when these symptoms are new or different from a person’s usual migraine aura.
Headache associated with fever, significant systemic illness, unexplained weight loss or immunosuppression may also require investigation for a secondary cause.
A new headache beginning after age 50, particularly when persistent or progressive, should be medically assessed.
Headaches that become progressively more frequent or severe, or that represent a significant change from a person’s usual headache pattern, should also be evaluated.
Headaches that are strongly positional, meaning substantially different when standing compared with lying down, or headaches consistently triggered by coughing, sneezing, straining or exertion, may occasionally indicate an underlying secondary cause and should be discussed with a healthcare professional.
New or substantially different headaches during pregnancy or the postpartum period should not automatically be attributed to migraine, as secondary causes of headache are particularly important to consider during these periods.
The presence of one of these features does not necessarily mean that a dangerous condition is present. Rather, these are features that warrant appropriate medical assessment rather than automatically assuming that the headache is migraine.
Urgent medical assessment is particularly important for a sudden severe or thunderclap headache; a headache associated with new weakness, difficulty speaking, significant confusion, loss of consciousness or seizure; a severe headache associated with fever and significant illness; or a headache that is dramatically different from anything previously experienced.
When in doubt about a severe new headache or new neurological symptoms, seeking urgent medical assessment is appropriate.
Medical assessment is appropriate when headaches are frequent, disabling, changing significantly or difficult to control.
This is particularly important when headaches are becoming progressively more frequent, acute medications are being required frequently, headaches are interfering substantially with work or normal activities, or current treatments are no longer providing adequate control.
New or substantially changed headaches should not automatically be assumed to be migraine.
