Do creatine make you bloated

You’ve probably encountered the term “Creatine” in chats with athletes, fitness enthusiasts, or even glimpsed it on your TV screen. But let’s get down to the nitty-gritty: today, we’re taking a look into the science of Creatine – exploring its essence, understanding its working, and tackling the burning query – does Creatine genuinely cause stomach bloating or is that just a myth?

Understanding creatine


Creatine is a widely used dietary supplement that has gained popularity among athletes, fitness enthusiasts, and bodybuilders for its potential to enhance performance and muscle growth. However, like any supplement, creatine has also been the subject of various claims and concerns. One common question that arises is whether creatine consumption leads to bloating. In this article, we will explore the science behind this claim to determine whether creatine truly causes bloating or if it’s merely a myth.

Understanding Creatine: What is Creatine
Before delving into the bloating aspect, it’s crucial to understand what creatine is and how it works. Creatine is a naturally occurring compound found in small amounts in certain foods and synthesized in the human body, primarily in the liver and kidneys. It plays a vital role in supplying energy to cells, especially during short bursts of high-intensity physical activity.

Myth or Reality: Does Creatine Cause Bloating?

Myth or Reality

The claim that creatine causes bloating largely stems from the belief that creatine draws water into muscle cells, leading to temporary water retention and, subsequently, bloating. While it is true that creatine can cause an increase in water content within muscle cells, this effect is not synonymous with the uncomfortable abdominal bloating often associated with overeating or digestive issues.

The Water Retention Mechanism:

When you consume creatine, it helps increase the levels of phosphocreatine in your muscles. This, in turn, supports the generation of adenosine triphosphate (ATP), a molecule that fuels muscle contractions. As your muscles take in more water to maintain balance, they can become slightly fuller. However, this water retention occurs within the muscle cells themselves and not in the spaces between tissues, which is where traditional bloating occurs.

Addressing the Bloated Feeling:

It’s important to distinguish between the mild, localized water retention within muscle cells and the more generalized bloating that affects the abdomen. Creatine-related water retention is generally limited to muscles and doesn’t typically cause discomfort or the sensation of being bloated. If an individual experiences abdominal bloating while using creatine, it may be due to other factors such as improper dosing, pre-existing digestive issues, or sensitivity to certain ingredients in the supplement.

Dosage and Hydration:

To minimize any perceived bloating associated with creatine usage, it’s recommended to stick to the appropriate dosage as suggested by health professionals or the product label. Additionally, staying adequately hydrated is essential. Creatine draws water into muscle cells, and staying hydrated helps maintain the balance between intracellular and extracellular water levels.


The notion that creatine causes bloating is largely a misconception. While creatine supplementation can lead to mild water retention within muscle cells, this effect is not the same as the abdominal bloating often associated with digestive discomfort. Proper dosing, hydration, and understanding the physiological processes involved in creatine’s mechanism of action can help athletes and individuals make informed decisions about its usage without unnecessary concern about bloating. As always, consulting with a healthcare professional before starting any new supplement regimen is advisable.

What Nutritionist Say about Creatine and Bloating

The following is a brief explanation from Dr. Jose Antonio Ph.D., a professor at Nova Southeastern University and CEO of the International Society of Sports Nutrition, who addresses this question about creatine bloating in the only manner he knows how.

Creatine Bloating: Some people say creatine made them bloated. Is there any scientific evidence behind these claims?

JA: The problem with the word ‘bloated’ is that it has no scientific meaning. How do you measure bloatedness? If someone says they are bloated, how can you even argue against it?
If someone says they weigh more, that’s easy to measure. If you ‘feel’ bloated (whatever that means to you) and that feeling bothers you, then by all means quit taking creatine.

Dosage of Creatine


When it comes to the recommended daily dosage of creatine, there is some variation among sources. However, the general consensus is as follows:
Loading phase: During the loading phase, it is recommended to take 20-25 grams of creatine per day, split into 4-5 equal doses, for a duration of 5-7 days. This phase is typically recommended for those who are new to creatine supplementation and aims to rapidly increase the amount of creatine stored in the muscles.

Maintenance phase: Once your muscles are fully saturated with creatine, a lower daily dose is required to maintain this level. It is generally recommended to take 3-5 grams of creatine per day. This dosage can be adjusted based on body weight, with a guideline of 14 mg per pound of body weight or 30 mg per kilogram of body weight
It’s important to note that taking more than the recommended dosage of creatine is not necessary and may lead to side effects such as stomach discomfort and bloating. Additionally, it’s always a good idea to consult with a healthcare professional or a registered dietitian before starting any new supplement regimen to ensure it aligns with your individual needs and goals.

Side effects of Creatine

Risks of creatine

Creatine is generally considered safe when taken at the recommended dosage. However, some people may experience side effects, including:

Gastrointestinal issues: Occasionally, a few individuals might experience some stomach discomfort, diarrhea, or a feeling of bloating when they start taking creatine. This can be a temporary adjustment as your body gets used to the supplement. If these effects persist, it’s a good idea to consult a healthcare professional.

Weight gain: One thing to keep in mind is that creatine can lead to weight gain, but it’s not the kind of gain that should ring alarm bells. The weight increase is often due to the muscles holding onto more water. It’s like your muscles are getting all pumped up and hydrated – a good thing for muscle health and strength.

Muscle cramps and strains: For a small number of folks, muscle cramps or strains might tag along with creatine usage. This could be due to the muscles working differently or perhaps needing a bit more time to adapt. Remember, everyone’s body is unique, so it’s all about finding your own groove.

Dehydration: Here’s a heads-up: creatine can play a trick on your hydration levels if you’re not getting enough water. To keep things on the up and up, just make sure you’re sipping that H2O regularly. It’s like giving your muscles the refreshing drink they deserve.

Liver and kidney damage: Now, about those worries regarding liver and kidney health. While there’s been some talk about high doses of creatine causing issues, it’s essential to know that this is incredibly rare. Plus, the research isn’t quite clear-cut yet. To be on the safe side, sticking to recommended doses and checking in with a healthcare pro can help ease any concerns.
It’s important to note that most of these side effects are mild and go away on their own. However, if you experience severe or persistent side effects, you should stop taking creatine and consult with a healthcare professional.

How Long It Take Creatine to Work

Creatine results can take time to show up, and the timeline can vary depending on the individual and the dosage. Here are some key points from the search results:
Loading phase: During the loading phase, which lasts 5-7 days, you can take 20-25 grams of creatine per day to rapidly increase the amount of creatine stored in the muscles.
You might not see a change in the first few days, but you can expect to see results within the first two weeks
These results can show up in your water retention, which can spike more easily than your resting creatine stores

Maintenance phase: Once your muscles are fully saturated with creatine, which can take about 7 days, you can start experiencing some of its benefits
It’s important to note that you won’t experience the performance benefits until full saturation, which can take up to 4 weeks. During this period, you may experience some side effects such as bloating and digestive discomfort

Consistency is key: To see the benefits of creatine, it’s important to take it consistently and at the recommended daily dosage. Creatine’s effects are systemic, meaning it needs to build up in your system over a period of days or weeks to work effectively.

Therefore, taking creatine regularly, even on non-training days, is more important than the specific timing.
In conclusion, creatine results can take time to show up, and the timeline can vary depending on the individual and the dosage. You can expect to see results within the first two weeks during the loading phase, and up to 4 weeks during the maintenance phase. Consistency in taking the recommended daily dosage of creatine is key to seeing its benefits.
