If you've noticed that you're heading to the bathroom more than usual after you've consumed creatine, you might be wondering - does creatine make you poop?

Here, we'll provide you with all the answers, from whether creatine affects your bowels to potential side effects of creatine and more.

While it may be great for muscle growth, increasing overall muscle mass, and improving athletic performance, there have been reports of creatine intake impacting gastrointestinal health and having a laxative effect.

Even though this isn't a common side effect of taking creatine supplements, some individuals have commented on gastrointestinal discomfort and pain, such as stomach cramps and unusual bowel movements.

With this, however, most individuals that experience frequent bowel movements after taking creatine monohydrate have either consumed a higher creatine dosage than recommended or mixed it with other stimulants such as pre-workout and caffeine.

Does Creatine Make You Poop More?

As mentioned above, whether it makes you poop more can largely be attributed to several factors, such as the amount of creatine you are consuming and how you are taking creatine.

Too much creatine, for example, will cause your body to remove it as waste, causing you to poop more.

Another reason it makes you poop more could be due to the creatine loading phase, where you're consuming more than the recommended dose of creatine.

During this phase, you will consume up to 20-25 grams of creatine per day for about five to seven days.

Consuming such high doses of creatine could cause some adverse reactions on your gastrointestinal tract and cause you to poop more.[1]

Why Does Creatine Supplementation Make You Poop More?

Even though creatine can improve physical performance and is ideal for those looking for weight loss or to increase muscle mass, loading up on creatine can make you poop more.[2]

To understand why creatine supplementation can make you poop more, it's essential to first understand how creatine works in the body.

Creatine is a natural substance in the body, but users consume additional creatine to help make more of a substance called adenosine triphosphate (ATP) that helps strengthen muscles.

ATP doesn't just improve athletic performance,  but it also helps with exercise endurance and more.

When excessive amounts of creatine are consumed, it's not properly digested; thus, creatine will remain in the intestines and continue to draw water from other body parts.

This extra amount of water in the intestines will cause you to poop more, affecting the overall digestion process. In the long run, this could lead to GI distress and, eventually diarrhea.

How To Solve Creatine Poops (Expert Tips)

Whether you’re looking to solve or prevent creatine poops, here are some expert tips to help you get started.

Lower The Dose Of Your Creatine

As most of this is attributed to a high consumption of creatine supplements, one of the best ways to solve creatine poops is to stick with your recommended doses.

When it comes to recommended doses, you’re looking at a creatine dosage of no higher than 10g a day.

Just taking three to five grams of creatine a day should be more than sufficient in providing you with benefits and preventing any unwanted side effects.

If you're worried about taking a single serving all at once, you can also split it up into two doses.

Change How You Are Mixing Creatine

If you are mixing your creatine with a pre-workout or caffeine, that could be what's giving you the creatine poops.

As pre-workouts come with a lot of caffeine and chemicals, the combination of creatine could lead to diarrhea and other undesirable side effects on the body.

What Are Some Other Potential Side Effects Of Creatine

While diarrhea and poop are one of the side effects of creatine, what are some other side effects that can be attributed to creatine?


Bloating is definitely a potential side effect of creatine, as consuming creatine causes fluid retention.

When you consume creatine, it draws water into your muscle cells - thus causing water retention.

With this water retention, your body will hold water - which can cause bloating and discomfort around your tummy area.

You can get diarrhea from creatine - especially if you’re consuming excessive amounts of creatine.

Studies have shown that athletes who consumed more than 10 grams of creatine supplements in a single serving experienced discomfort such as diarrhea and stomach upset.


While consuming a creatine supplement directly won't make you fart, it can be one of the side effects. As mentioned, you can get bloating from creatine as your intestines are working overtime.

With all of that bloating, it can also lead to an increased amount of gas which can lead to farting.


Can creatine cause constipation? The simple answer to that is no. It's likely that creatine can cause you to have diarrhea, but not so much constipation.

If you end up having it, however, this is likely because you're not hydrating enough, especially because creatine makes you dehydrated.
