Headaches When Going Vegan: Causes & Solutions for Relief

If you have recently transitioned to a vegan diet and are experiencing headaches, you are not alone. Headaches when going vegan are a common occurrence for many individuals due to various reasons such as nutrient deficiencies and dehydration.

However, fret not, as there are numerous solutions available to relieve these headaches and help you smoothly transition into a vegan lifestyle. By understanding the causes and making some simple changes, you can avoid or manage headaches and enjoy all the benefits of a vegan diet.

Why Do Headaches Occur When Going Vegan?

Transitioning to a vegan lifestyle can have numerous benefits for both individual health and the environment. However, like any significant dietary change, it can also come with side effects, including headaches.

But why exactly do headaches occur when going vegan?

Vegan Withdrawal Symptoms

One reason for headaches during the transition to a vegan diet is the withdrawal symptoms experienced when eliminating certain foods. Animal products, such as meat and dairy, contain high levels of fat, salt, and sugar, which can be addictive. When these foods are removed from the diet, the body may experience withdrawal symptoms, including headaches.

To alleviate these withdrawal symptoms, individuals can gradually reduce their intake of animal products over time instead of stopping cold turkey, which can lead to more severe symptoms.

Nutrient Deficiencies

Another reason for headaches when going vegan is a potential deficiency in certain nutrients. When making the switch to a plant-based diet, it is essential to ensure adequate intake of key vitamins and minerals, such as vitamin B12, iron, and omega-3 fatty acids. A deficiency in these nutrients can lead to headaches and other health problems.

To combat nutrient deficiencies, vegans can incorporate fortified foods or supplements into their diets and ensure a varied intake of plant-based foods with high nutrient content.


Dehydration can also be a cause of headaches when going vegan. A plant-based diet typically contains higher water content, and individuals may not be accustomed to drinking enough fluids to compensate for this change.

To prevent dehydration and subsequent headaches, individuals should make a conscious effort to stay hydrated by drinking plenty of water and other fluids throughout the day.

By understanding the reasons behind headaches when going vegan, individuals can take proactive steps to prevent and alleviate any discomfort during the transition to a plant-based lifestyle.

Nutrient Deficiencies and Headaches on a Vegan Diet

Transitioning to a vegan diet can be challenging, and some people experience headaches during the process. The cause of these headaches could be due to nutrient deficiencies.

Vegan diets often require more planning and consideration to ensure a well-balanced intake of nutrients. Some key nutrients that can be lacking in a vegan diet include vitamin B12, iron, zinc, and omega-3 fatty acids. Deficiencies in these nutrients can lead to headaches and other symptoms.

Vitamin B12Fortified plant-based milks, nutritional yeast, supplements
IronLeafy greens, beans, tofu, fortified cereals
ZincNuts, seeds, fortified cereals, beans
Omega-3 Fatty AcidsFlaxseeds, chia seeds, hemp seeds, walnuts

If you are experiencing headaches during your transition to a vegan diet, it may be beneficial to track your nutrient intake and consider incorporating more plant-based sources of these key nutrients into your meals.

It may also be helpful to consult a registered dietitian who can provide personalized guidance on meeting nutrient needs on a vegan diet.

Calcium Deficiency and Headaches

Calcium is another nutrient that can be lacking in a vegan diet. Low calcium levels can cause headaches and migraines. While dairy products are a common source of calcium in non-vegan diets, vegans can obtain calcium from fortified plant milks, tofu, dark leafy greens, almonds, and sesame seeds.

It is important to ensure adequate calcium intake to prevent symptoms such as headaches and osteoporosis.

Overall, keeping track of your nutrient intake and consulting a registered dietitian can help prevent headaches caused by nutrient deficiencies on a vegan diet.

Dehydration and Headaches on a Vegan Diet

While transitioning to a vegan diet can be a positive lifestyle change, it can also lead to dehydration, a common cause of headaches. Dehydration occurs when the body loses more fluids than it consumes, causing a range of symptoms, including headaches.

When switching to a vegan diet, it’s important to pay close attention to your water intake to prevent dehydration. Many plant-based foods, such as fruits and vegetables, have a high water content, which can support hydration. However, it’s still crucial to drink enough water throughout the day to stay hydrated.

If you’re not sure how much water your body needs, an easy way to calculate it is by dividing your body weight in pounds by two. The resulting number is the minimum amount of water in ounces that you should be drinking daily.

If you’re experiencing headaches due to dehydration, drinking water can provide relief. However, it’s important to continue drinking water regularly to avoid future headaches. Additionally, incorporating more hydrating foods like watermelon and cucumbers into your diet can help prevent dehydration.

Food Triggers and Headaches

While changing to a vegan diet can bring a lot of health benefits, it can also lead to certain side effects such as headaches. One possible cause of these headaches could be certain food triggers.

Foods That Can Trigger Headaches

Some common food triggers that can cause headaches on a vegan diet include:

  • Caffeine: Found in tea, coffee, chocolate, and some sodas.
  • Artificial sweeteners: Such as aspartame and saccharin, found in many processed foods and drinks.
  • Alcohol: Especially red wine as it contains histamine, which can trigger headaches in some people.
  • Processed foods: Such as packaged snacks, deli meats, and frozen meals that are high in salt, sugar, and preservatives.

If you suspect that any of these foods are causing your headaches, try eliminating them from your diet and see if the headaches improve. Keeping a food diary can also be helpful in identifying potential triggers.

Replacing Trigger Foods with Nutrient-Dense Alternatives

Eliminating trigger foods from your diet doesn’t mean you have to give up the flavors and textures you enjoy. Instead, try replacing them with nutrient-dense alternatives that can provide similar benefits without the negative side effects.

For example, if you’re craving something sweet, try snacking on fresh fruits or making a fruit smoothie instead of reaching for a sugary snack. If you need a caffeine boost, consider switching to herbal tea or experimenting with different roasted grain beverages.

By replacing trigger foods with healthier alternatives, you can not only reduce your risk of headaches but also improve your overall health and wellbeing.

Lifestyle Changes To Avoid Headaches on a Vegan Diet

Transitioning to a vegan diet can cause headaches and other discomforts for some individuals. However, there are steps that can be taken to prevent headaches and other symptoms from occurring. Here are some lifestyle changes to consider:

1. Gradual Transition

Going cold turkey on animal products can be a shock to the system, so it’s important to transition to a vegan diet gradually. This will give your body time to adjust to the new diet and reduce the likelihood of headaches and other symptoms.

2. Stay Hydrated

Dehydration can be a trigger for headaches, so it’s essential to drink plenty of water throughout the day. Aim for at least eight glasses of water a day and more if you’re particularly active.

3. Balanced Diet

Make sure your vegan diet is balanced and includes a variety of fruits, vegetables, whole grains, legumes, nuts, and seeds. This will ensure that you’re getting all the nutrients your body needs, which can help prevent headaches.

4. Monitor Your Protein Intake

Protein is an essential nutrient, but some vegans don’t get enough of it in their diet. Make sure you’re consuming enough protein from plant-based sources such as tofu, tempeh, lentils, and quinoa. Lack of protein can lead to headaches and other symptoms.

5. Get Enough Sleep

Sleep is crucial for our overall health, and lack of sleep can lead to headaches. Aim for at least 7-8 hours of sleep a night to prevent headaches and other symptoms.

6. Reduce Stress

Stress can be a trigger for headaches, so it’s important to find ways to manage stress levels. This can include meditation, yoga, deep breathing exercises, or simply taking a walk in nature.

By following these lifestyle changes, you can reduce the likelihood of experiencing headaches on a vegan diet. If your headaches persist, it’s important to consult a doctor to rule out any underlying health issues.

Supplements for Headache Relief on a Vegan Diet

Many vegans may experience headaches due to nutrient deficiencies, dehydration, or food triggers. While dietary changes may help relieve headaches, supplements can also be useful in reducing the frequency and severity of headaches.

Note: Before taking any supplements, it is important to consult with a healthcare professional to ensure they are safe and appropriate for your individual needs.

1. Vitamin B12

Vegans may be at risk of vitamin B12 deficiency, which can cause symptoms such as headaches, fatigue, and weakness. Taking a vitamin B12 supplement can help prevent deficiency and alleviate associated symptoms. The recommended daily intake of vitamin B12 for adults is 2.4 micrograms.

2. Magnesium

Magnesium is an essential mineral that plays a role in many bodily functions, including muscle and nerve function. Some studies suggest that magnesium supplementation may help reduce the frequency and severity of headaches. The recommended daily intake of magnesium for adults is between 310-420mg.

3. Coenzyme Q10

Coenzyme Q10 is a nutrient that is involved in energy production in the body. Some studies suggest that it may help reduce the frequency and severity of migraines. The recommended dose of coenzyme Q10 for migraine prevention is typically between 100-300mg per day.

4. Riboflavin (Vitamin B2)

Riboflavin is a B vitamin that is involved in energy production and helps maintain healthy skin, eyes, and nervous system. Some studies suggest that riboflavin supplementation may help reduce the frequency and severity of migraines. The recommended daily intake of riboflavin for adults is between 1.1-1.3mg.

Supplements can be a helpful tool to alleviate headaches on a vegan diet. However, it is important to remember that a well-planned and varied vegan diet can provide all the necessary nutrients to support a healthy lifestyle. If you are experiencing frequent or severe headaches, it is important to speak with a healthcare professional to determine the underlying cause and appropriate treatment.

3. Monitor Your Nutrient Intake

Ensure you are getting enough nutrients like iron, calcium, and vitamin B12 which are commonly found in animal products. You can obtain these nutrients from plant-based sources like leafy greens, beans, and fortified cereals. It may also be necessary to take supplements to ensure you are meeting your nutritional needs.

4. Identify Food Triggers

Some people may have sensitivities to certain foods, and this can trigger headaches. Keep a food diary and identify any foods that seem to cause headaches. Avoiding these foods can help reduce the frequency of headaches.

5. Get Enough Sleep

Sleep deprivation can also cause headaches. Make sure you are getting enough sleep every night, and establish a regular sleep routine.
