Exploring Creatine: Benefits, Usage, and Its Role in IBD


Quality Rating

Creatine is a popular supplement known for its potential to enhance athletic performance and muscle growth. However, its benefits may extend beyond the gym, potentially offering therapeutic effects for individuals with conditions like Inflammatory Bowel Disease (IBD). Let’s dive into what creatine is, how it works, how to use it, and explore any existing research on its role in IBD.

What is Creatine?

Creatine is a naturally occurring compound found in small amounts in certain foods and synthesized by the human body. It’s primarily stored in the muscles, where it plays a crucial role in energy production. The majority of creatine is found in meat and fish, though it’s also produced by the liver, kidneys, and pancreas.

What Does Creatine Do?

Creatine is involved in the production of adenosine triphosphate (ATP), the primary energy carrier in cells. During high-intensity, short-duration activities like sprinting or weightlifting, the demand for ATP increases. Creatine helps replenish ATP stores, allowing for enhanced performance and reduced fatigue.

Key Benefits of Creatine:
  1. Improved Athletic Performance: Creatine supplementation is well-documented to enhance strength, power, and exercise performance.
  2. Increased Muscle Mass: It supports muscle growth by promoting protein synthesis and drawing water into muscle cells, leading to increased muscle volume.
  3. Enhanced Recovery: Creatine may help reduce muscle damage and inflammation following intense exercise, aiding in quicker recovery. (PMID: 28615996)

How to Use Creatine

Creatine is typically consumed in supplement form, with creatine monohydrate being the most common and well-researched type.

Guidelines for Creatine Use:
  1. Dosing: A maintenance dose of 3-5 grams per day is recommended to sustain elevated creatine levels. Creatine monohydrate is the best form.
  2. Timing: Creatine can be taken at any time of the day! Add it to your morning coffee, smoothie, or other beverage of choice.
  3. What about a loading phase? You may have heard that a loading phase is needed to fully saturate the muscles, but this is not necessary. Creatine at the above dose daily is adequate.

Creatine and Kidney Health: Debunking the Myths

One common myth about creatine is that it may harm the kidneys. This misconception has been debunked by numerous studies, which consistently show that creatine supplementation does not adversely affect kidney function in healthy individuals.

Key Points on Creatine and Kidney Health:
  1. Scientific Evidence: Extensive research, including long-term studies, has demonstrated that creatine does not impair kidney function. These studies involve regular monitoring of kidney health markers such as serum creatinine and glomerular filtration rate (GFR).
  2. Myth Debunking: The myth likely originated from the fact that creatine supplementation can slightly increase serum creatinine levels, a marker often used to assess kidney function. However, this increase is not indicative of kidney damage but rather reflects higher creatine levels in the body.
  3. Safe Usage: For individuals with pre-existing kidney conditions, it’s always best to consult a healthcare provider before starting any new supplement. However, for healthy individuals, creatine is considered safe and does not pose a risk to kidney health.

Creatine and IBD: Current Research and Potential Benefits

Inflammatory Bowel Disease, including Crohn’s disease and ulcerative colitis, involves chronic inflammation of the gastrointestinal tract. Patients with IBD often face challenges related to nutrition, muscle mass, and overall energy levels. Emerging research is beginning to explore the potential benefits of creatine supplementation for IBD patients.

Key Points on Creatine and IBD:
  1. Anti-Inflammatory Properties: Some studies suggest that creatine may have anti-inflammatory effects, which could be beneficial in managing IBD.
    • Further studies in IBD must be conducted. However, it is interesting to note that studies conducted on those participating in ironman competitions  found that creatine supplementation reduced blood levels of pro-inflammatory cytokines and had the potential to lower pain sensitivity associated with inflammation (PMID: 33922654).
  2. Muscle Preservation: IBD patients often struggle with muscle wasting and reduced strength due to prolonged inflammation and malnutrition.
    • Creatine’s role in promoting muscle mass and strength could help mitigate these issues along with inflammation control and adequate dietary intake.
  3. Energy and Fatigue: Creatine might help improve energy levels and reduce fatigue, enhancing the quality of life for individuals with IBD.
    • It’s important to understand that underlying factors of fatigue should be addressed before simply jumping into creatine supplementation. Some things that may contribute to IBD fatigue include: uncontrolled inflammation, decreased food intake, low nutrient levels (particularly iron and B12), poor sleep, and dehydration.


Creatine is a versatile supplement with well-established benefits for athletic performance, muscle growth, and recovery. Emerging research suggests that it may also offer potential benefits for individuals with IBD, particularly in reducing inflammation and preserving muscle mass. While more research is needed to fully understand the therapeutic potential of creatine for IBD, these preliminary findings are promising.

Despite common myths, extensive studies have shown that creatine does not harm kidney health in healthy individuals. As always, it is crucial to consult with a healthcare provider to tailor any supplementation strategy to individual health needs and conditions.
