I have inspected PhenQ’s ingredients for this article to find out if they may be causing you headaches. Additionally, I have searched for ways that will help you reduce their incidence.

Key Points:

  • Headaches are rightly associated with PhenQ.
  • Nopal, chromium picolinate, and caffeine are some ingredients that may trigger headaches in users.
  • The headaches can be linked to over-caffeination, low blood sugar, or dehydration caused by PhenQ intake.
  • Find out more about PhenQ on its official website.

Research suggests that obese individuals have a higher risk of experiencing a headache than those with normal BMI. Moreover, approximately 41 percent of individuals get headaches while losing weight.

And, PhenQ may raise this risk because it has caffeine which messes with the neurotransmitters and other ingredients that may decrease blood sugar levels and increase dehydration.

In the following sections, I’m going to share some scientific evidence with you about why PhenQ may trigger headaches and what you can do to prevent them.

So, keep reading to find out all about it.

Why Does PhenQ Cause Headache?


PhenQ’s real reviews indicate that headaches are indeed a common affair for users. The ingredients that may be suspected to cause them include caffeine, nopal, and chromium picolinate.

The reasons why headaches might get triggered by these ingredients include dehydration, low blood sugar, an overuse symptom, or a withdrawal side effect.

But there is more in the upcoming sections, so keep following.

Caffeine May Trigger Headaches As A Withdrawal Symptom Or Due To Overuse.

PhenQ contains 150 mg of caffeine anhydrous per dose because it causes an energy boost and increases thermogenesis. Plus, it is recommended that you take two pills per day for at least 3 weeks (A month).

In a 2014 review, specific remarks about caffeine and headache can be read as long-term overconsumption of caffeine (more than 450 mg per day) can induce abnormal changes in the peripheral and central nervous system, which may increase the frequency of primary headaches and analgesic-overuse headaches.

According to the International Classification of Headache Disorders (ICHD-3), consuming over 200 mg of caffeine for over 2 weeks may trigger withdrawal headaches if this pattern is interrupted.

Moreover, a review of 28 studies was published in 2020 that investigated caffeine as a migraine trigger and found that it caused migraines in 2% to 30% of the participants.

The reason why the caffeine in PhenQ may trigger migraines is that it causes magnesium loss and dehydration.

Now, magnesium has a role in neuromuscular conduction and nerve transmission, and hence its deficiency may be a factor that induces migraines and chronic pains.

Similarly, caffeine has a diuretic effect which may lead to dehydration and, ultimately, headache.

Nopal May Cause Dehydration, Leading To Headaches.

PhenQ contains 20 mg of nopal per serving because of its ability to cause fullness and induce weight loss.

According to WebMD, headache is a common side effect of Nopal.

One reason could be that nopal shows the potential to lower blood sugar levels, but if they drop too low, you may experience hypoglycemia which can manifest in headaches.

Headaches Are Associated With Chromium As Their Common Side Effect.

PhenQ provides you with 80 mcg of chromium per dose. It has the potential to increase lean muscle mass and decrease body fat which supports healthy weight loss. report chromium as a common side effect of chromium picolinate supplementation.

Likewise, according to a phase IV clinical trial performed by eHealthme, in 917 people who experienced side effects due to chromium intake, the headache was more commonly reported in females, in 40-49 years old, or in individuals who had been taking it for up to 6 to 12 months.

How To Cure Headache Caused By PhenQ?

There are two ways that you can go about dealing with PhenQ headaches. You can either shift to a weight loss supplement that doesn’t trigger your headache or, if you want to continue taking PhenQ, then countering the reasons behind it may relieve it.

So, in this section, I will recommend you a non-stimulant weight loss supplement and some effective remedies to help you get rid of the pain.

1. Check Your Sugar Levels And Act Accordingly.

As mentioned above, nopal in PhenQ may level down your sugar levels. Apart from this, other ingredients in it, like chromium picolinate and α-Lacy’s Reset, reinforce this action by increasing insulin sensitivity and triggering insulin release.

Learn more about the blood sugar-regulating properties of PhenQ in my detailed blog here.

On top of that, if you are going into a calorie deficit, there is a high chance that your headache is caused due to low glucose levels (below 70 mg/dL) in the blood.

Therefore, you might want to check your blood sugar levels and then take the right action, like drinking fruit juice and eating some carbs like crackers which may make you feel better.

2. Work On Keeping Your Body Hydrated.

The caffeine in PhenQ may trigger your migraine or headache, so the best approach may be to take the appropriate preventive measures.

You need to ensure that you are drinking enough water and try to exercise within 15 minutes to 2 hours (the time during which caffeine peaks in the blood) of consuming PhenQ to utilize the energy boost.

This may prevent headaches caused due to dehydration and over-caffeination.

In case you are getting headaches after cessation of PhenQ, they will most probably resolve in 7 days as you may fall out of caffeine dependence within this duration.

3. Try non-caffeine pills like PhenQ PM.

Caffeine in PhenQ is the predominant cause of headaches, so shifting to a stimulant-free alternative like PhenQ PM may resolve it.

PhenQ PM capsule pills

Unlike PhenQ, PhenQ PM doesn’t contain caffeine; instead, it contains all the ingredients that promote good sleep, help release stress, and enhance overnight fat burning.

You just have to take 4 pills of it with water 30 minutes to 1 hour before sleep, and it will speed up your metabolism, help you relax, and prevent late-night cravings.

Both PhenQ and PhenQ PM come at a retail price of $69.99, without any shipping costs, and with a 60-day money-back guarantee.

PhenQ Fat Burner – How to use without causing headaches?

The best way to avoid PhenQ side effects is by following the instructions recommended by the manufacturers.

Still yet, here are some things that you need to consciously take care of are:

  • Make sure that you stay hydrated and drink at least 8 glasses of water with your daily PhenQ doses.
  • PhenQ may suppress your appetite but monitor and fulfill your daily caloric and nutritional requirements to avoid headaches due to deficiencies and low sugar levels.
  • Monitor your daily caffeine intake; it should not exceed the USDA recommended 400 mg mark. If you are caffeine sensitive, then try to eliminate other caffeine sources from your day when you are following the PhenQ regimen.


Does PhenQ Affect Sleep?

Yes, PhenQ contains caffeine which stimulates the central nervous system to promote alertness and cause sleep disturbances. Therefore you should avoid the second dose near bedtime and take it in the evening.

Can You Take 2 PhenQ At Once?

Yes, you can take two pills at once. However, spacing the two doses may help to extend the appetite suppression, metabolism enhancement, and weight loss effect of the supplement throughout the day.
