Does Pre-Workout Make You Poop? Find Out the Truth Here!

Does Pre-Workout Make You Pee?

The most central stimulant in pre-exercise supplements is caffeine which could cause you to poop. Other ingredients that could cause you to poop are artificial sweeteners and amino acids.

This article will discuss why pre-workouts could cause you to poop and the most effective pre-workout supplements that will not cause you to go to the bathroom.

The Reason Why Pre-Workouts Can Cause You To Want To Poop

In this portion of this article, we’ll try to examine why your pre-workout could cause you to have to poop. To be clear, not everyone who participates in pre-workouts should make a mad dash to the toilet.

However, it also explains why some individuals might need to go through a mid-gymnasium for poop.

The pre-workout is usually high in Artificial Sweeteners.

Artificial sweeteners are commonly used in various supplements as an alternative to sugar that is low in calories.

Unfortunately, they can be challenging to digest and absorb.

Once the undigested sweetener is absorbed into the colon, bacteria will have an incredible time fermenting it. This creates methane and CO2.

As you’re probably aware, these two chemicals are gases that could cause abdominal discomfort.

But, if you consume a lot of sugar substitutes, bacteria in the colon might have a hard time keeping up with the demands.

In this situation, the sweetener that is not digested absorption of water into the colon leads to an urgent trip to the bathroom.

A study found that participants taking in 40g or more of isomalt a day noticed an increase in their frequency of bowel movements and watery stools.

Although it’s unlikely to consume these amounts of supplements for pre-workouts however, you could still consume enough to require a bowel movement afterward. The Pre Workout stage is typically high in caffeine.

Pre-workout is renowned for its high levels of caffeine. A typical pre-workout powder has as “little” as 150mg of caffeine in a serving and can go to a staggering 300mg of caffeine.

While coffee is famous for making you require a puke.

However, caffeine does not contain caffeine; so what argument are you trying to convey, Robb?

This is a great question.

It’s not caffeine; however, research has shown that caffeinated coffee causes you to poop more than decaffeinated coffee.

In the case of one study, 12 subjects were given caffeinated or decaffeinated beverages, and water and 1000 calories were dispersed randomly over 10 hours.

(The caffeinated coffee had 150mg of caffeine, by the way.)

According to the research, caffeinated coffee resulted in 60 percent more stool movements than water and 23 percent more bowel movements than decaf coffee.

Therefore, caffeinated coffee triggers more constipation than decaff, which suggests caffeine may stimulate bowel movements.

We now know which ingredients cause you to need a pee; let’s look at 3 fantastic pre-workout drinks that do not contain these ingredients.

Additionally, I greatly admire Genius for its role as a supplement business.

The product (like the one below) comes from 3 3rd test for purity and potency, which means it is safe to trust their labels.

(It’s fantastic that many supplement companies provide false information on their labeling.)

Potential Drawbacks

Suppose you substitute inexpensive ingredients (ahem, caffeine, caffeine, and artificial sweeteners) with organic alternatives. In that case, you’ll end up with more expensive supplements.

However, it is passed on to you, so it’s more than the usual pre-workout supplement.


In conclusion, certain pre-workout supplements aren’t a good idea for those who want to prevent a mid-workout pee.

You can blame the artificial sweeteners and the caffeine in their products for that.

But don’t panic…

Many amazing pre-workouts do not contain both artificial sweeteners and caffeine.
