Yes, PhenQ has stimulatory properties and may cause jitters.

Stimulants in fat burners make them highly effective at fat burning. But the high stimulatory content also comes with the side effects like jitters, anxiety, and headaches.

As PhenQ is a potent fat burner with thousands of success stories proving its fat-burning properties, we often get asked if it has stimulants, too, and can cause jitters like other fat burners.

Key Points:

  • PhenQ is a caffeine-inclusive fat burner, so overdosing can lead to jitters.
  • Caffeine intolerance is another reason for feeling jittery with the diet pill.
  • You can avoid jitters with PhenQ by sticking to the recommended dose, managing your overall caffeine intake, and opting for the non-caffeinated version of PhenQ.
  • Find more about PhenQ on their official website.

However, the fat burner is formulated such that the amount of the stimulant isn’t harmful if you follow the dose recommendations and take necessary precautions to avoid jitters and other stimulatory side effects.

In the upcoming sections, read how much caffeine is in PhenQ, when it can make you feel jittery, and how to escape the fidgety feelings with PhenQ.

But first, let’s see how strong a stimulant is PhenQ;

Is PhenQ a Stimulant?

PhenQ has some stimulatory properties owing to caffeine anhydrous among its active ingredients.

However, it is a multi-ingredient fat burner having many non-stimulatory fat burners, only a moderate amount of caffeine, and no other psychostimulatory compounds.

So, overall, it only has a mild stimulatory nature.

It is not that much of a strong stimulant that can get you on a high soon after the dose, make your heart throb like crazy, or have severe withdrawal effects.

Instead, its stimulatory content is too low to fear such severe side effects.

Overall, 2 pills of PhenQ (the recommended daily dose) give you 285 mg of caffeine, which is a bit more than two cups of Café Latte.

Resultantly, its stimulatory effect is only potent enough to give you a good energy uplift throughout the day or, on the negative side, cause sleeplessness if taken too late.

So, most users tolerate PhenQ stimulatory effects well and are happy that this dieting supplement does not make them jittery as other brands do. For instance, see this Trustpilot review by Angellirika.

On the other side, some people also complain of heart throbbing, jitters, and agitation in negative PhenQ reviews, though such cases are rare.

In these cases, there are usually 3 possible reasons that make you get jitters with this fat burner.

In What Cases Can PhenQ Make You Jittery?


PhenQ can cause jitters in the following circumstances;

1. Taking A High Dose

You can feel jitters if you take over 2 tablets of caffeinated PhenQ daily.

As each pill has 142.5 mg of caffeine, a dosage above the recommendation means you would be taking more caffeine than the safe limit.

Besides that, it is also harmful to take both pills at once because, in that case, you would be ingesting too much-concentrated caffeine at once, which can overwhelm your nervous system, making you fidgety and irritable.

2. Using Caffeinated PhenQ With Caffeine Sensitivity

If you are hypersensitive to caffeine and get irritated by coffee or tea, the caffeinated PhenQ is not for you.

That’s because caffeine is one of the main thermogenic components of this product and may cause hypersensitivity effects, including agitation, jitters, and anxiety.

In fact, caffeine sensitivity is the #1 cause of PhenQ causing jitters and headaches. That’s why you will see most of the negative PhenQ reviews coming from people with low caffeine tolerance.

3. Drinking a Lot Of Coffee With PhenQ

Most people can tolerate a daily caffeine intake of 400 mg.

Yes, most, but not all.

In reality, everyone has a different caffeine tolerance, so the amount that can cause jitters also vary from person to person.

– With Caffeine Sensitivity, Coffee With PhenQ is Not A Good Combination

Some people are highly caffeine-sensitive and can tolerate only a small amount of concentrated caffeine.

If you’re one of them, you may get jittery by consuming coffee while on PhenQ, as the combined caffeine dose goes way beyond the safe threshold.

Also, some reviews like this one from Jorgen Hanson suggest that sensitive people feel caffeine side effects even when they can tolerate a few cups of coffee in their routine.

The probable reason here is your coffee has caffeine diluted with water and milk, but in PhenQ tablets, it is in a highly concentrated anhydrous form.

Hence, I suggest that caffeine-sensitive people do not consume coffee or caffeinated drinks and start with 1 pill to check their tolerance level.

And, if you want to avoid the risk of stimulants altogether, go for the caffeine-free version of PhenQ.


– With Normal Caffeine Tolerance, Jitters May Happen If You Don’t Lower Coffee Intake

Most people have moderate caffeine tolerance, meaning they can drink 3-4 cups of coffee without any trouble, but side effects appear above that.

However, taking 3-4 cups of coffee with PhenQ is not recommended as the combined caffeine intake would go beyond the safe limit.

How To Stop Jitters Caused By PhenQ?

To avoid jitters with PhenQ, do the following;

1. Never Exceed the Dose Recommendations

To prevent overdosing, you should always stick to the dosage guidelines on PhenQ’s official website, i.e., 2 pills daily, one with breakfast and the other with lunch.

You can also start supplementation with 1 pill daily to check your tolerance and familiarize your body with PhenQ ingredients.

2. Adjust Your Coffee Intake Accordingly

As PhenQ already has as much caffeine as 2 big cups of coffee, using more coffee or caffeinated beverages can lead to caffeine intake higher than your tolerance range.

So, adjusting coffee intake is important to keep overall caffeine intake under check.

Some of you will need to let go of the coffee completely, while others can still enjoy 1-2 cups, depending on their caffeine tolerance and the coffee type.

(See this post to figure out exactly how many cups of coffee you can take with PhenQ.)

And what if you used to have no issues with a moderate amount of coffee, but you still stopped taking it when you started PhenQ, and even then, you are feeling jittery like Jorgen Hanson did?

The probable reason here is that your coffee has caffeine diluted with water and milk, but in PhenQ tablets, it is in a highly concentrated anhydrous form, which is why it is hitting you hard, which can be truly upsetting.

To avoid this effect, you can start with a half dose (1 pill daily) and then switch to the total dose (2 pills daily) after 1-2 weeks when your body is well accustomed to the concentrated dose.

However, in all cases, I recommend ensuring that your daily caffeine consumption does not exceed the safe limit declared by the FDA (400 mg of caffeine/day).

3. If Caffeine-Sensitive, Use PhenQ PM Instead

Caffeine-sensitive people cannot take PhenQ due to the increased severity of caffeine-related side effects for them. But it does not mean they can’t benefit from the fat-burning ability of this effective diet pill.

Instead, PhenQ provides them with a caffeine-free, stimulant-free fat burner called PhenQ PM. It is a potent fat burner with no stimulant but vitamin and mind-relaxing compounds like choline.

Hence, this diet pill provides multiple benefits, including a metabolic boost, craving suppression, and calming effects to protect your nervous system against stimulatory compounds.
