What You'll Learn
Creatine is likely safe for most people when taken by mouth
Creatine is a chemical found naturally in the body, as well as in red meat and seafood. It is often used to improve exercise performance and muscle mass. Creatine is likely safe for most people when taken by mouth. Doses up to 25 grams daily for up to 14 days have been safely used. Lower doses of between 3 to 5 grams daily for up to 18 months have also been safely used. Creatine is possibly safe when taken long-term, with doses up to 10 grams daily for up to 5 years having been safely used.
Although creatine is likely safe for most people, there have been some reports of side effects. These include dehydration, upset stomach, and muscle cramps. However, it is important to note that these side effects may be related to excessive doses of creatine. For example, a 2008 study found that a 10-gram dose of creatine taken once daily increased the risk of diarrhea by 56%. Similarly, a 2003 study of college athletes found that those taking creatine had fewer cases of dehydration, muscle cramps, and muscle injuries than those not taking it. The study also found that creatine users missed fewer training sessions due to illness or injury.
While creatine supplementation is generally considered safe, there are some groups of people who should use caution. For example, creatine is possibly safe for children when taken by mouth short-term. Doses of 3-5 grams daily for 2-6 months have been safely used in children 5-18 years of age, while doses of 2 grams daily for 6 months have been safely used in children 2-5 years of age. However, there is not enough research to determine the safety of creatine for pregnant or breastfeeding women, so it is recommended that they avoid using it. Additionally, people with bipolar disorder or kidney disease should use caution when taking creatine, as it may worsen these conditions.
Some anecdotal reports suggest that creatine supplementation may cause muscle stiffness and increase the risk of muscle strain injuries. However, these claims have been refuted by several studies. One study examined 20 men for musculotendinous stiffness before and after creatine ingestion and found no increase in stiffness at any assessment load. Similarly, another study of college football players found that creatine supplementation did not increase the incidence of muscle cramps or injuries. Overall, while there may be some concerns about the side effects of creatine, the current evidence suggests that it is generally safe for most people when taken by mouth.

Creatine may cause muscle cramps
Creatine is a chemical found naturally in the body and is also present in red meat and seafood. It is often used to improve exercise performance and muscle mass. Creatine is involved in making energy for muscles. About 95% of it is found in skeletal muscle.
Creatine is likely safe for most people when taken by mouth. Doses up to 25 grams daily for up to 14 days have been safely used. Lower doses of up to 4-5 grams daily for up to 18 months have also been proven to be safe. Creatine is possibly safe when taken long-term. Doses up to 10 grams daily for up to 5 years have been used safely. However, excessive doses of creatine may cause digestive issues.
There are anecdotal reports suggesting that creatine supplementation may cause side effects such as an increased incidence of muscle strains, tears, and cramps. However, these claims have been refuted by several published studies. For example, a 2003 study of college athletes found that those taking creatine had fewer cases of dehydration, muscle cramps, or muscle injuries than those not taking it. They also missed fewer sessions due to illness or injury. Another study found that creatine supplementation improves muscular performance in older women. Based on the current evidence, creatine does not cause dehydration or cramping. It may even protect against these conditions.
It is important to note that creatine may interact with certain medications. As with any diet or supplement regimen, it is best to speak with a healthcare professional before taking creatine.

Creatine may cause an increase in musculotendinous stiffness
Creatine is a chemical found naturally in the body and is also present in red meat and seafood. It is often used to improve exercise performance and muscle mass. Creatine is involved in making energy for muscles, and about 95% of it is found in skeletal muscle.
While creatine is likely safe for most people, there are some reported side effects of taking creatine supplements, such as dehydration, upset stomach, and muscle cramps. Some anecdotal reports also suggest that creatine supplementation may cause an increase in musculotendinous stiffness, which could increase the chance of injury during exercise. However, these claims have been refuted by several studies.
In one study, twenty men were randomly assigned to a control or experimental group and examined for musculotendinous stiffness before and after creatine ingestion. The experimental group did not show any increase in musculotendinous stiffness at any assessment load, and there were no significant changes in any variables within the control group. Similarly, another study on college football players found that creatine supplementation did not increase the incidence of cramping or injury.
While creatine may not directly cause muscle stiffness, excessive doses can lead to digestive issues such as diarrhoea, abdominal pain, and bloody stools. It is always recommended to consult a healthcare professional before taking any supplements to assess whether they are right for you.

Creatine can be used to treat muscle cramps
Creatine is a chemical found naturally in the body and is also found in red meat and seafood. It is often used to improve exercise performance and muscle mass. While some sources suggest that creatine may cause muscle cramps, there is little evidence to support this claim. In fact, creatine monohydrate treatment has been found to alleviate muscle cramps associated with haemodialysis.
Creatine supplementation is one of the most popular athletic supplements, with sales surpassing $400 million in 2004. It is often used to improve exercise performance and increase muscle mass. However, there have been anecdotal reports that creatine supplementation can result in muscle cramps and dehydration. Despite this, over 200 studies have examined the effects of creatine on athletic performance, with many finding no increase in the incidence of cramping or injury.
For example, a study by Greenwood et al. (2003) found that creatine supplementation during college football training did not increase the incidence of cramping or injury. Additionally, a study by Poortmans et al. (2000) reviewed the adverse effects of creatine supplementation and found no evidence that it causes muscle cramps. Furthermore, a recent publication by Jäger et al. (2011) analysed the efficacy, safety, and regulatory status of novel forms of creatine, suggesting that the myth of creatine causing muscle cramps is unfounded.
While the majority of evidence suggests that creatine does not cause muscle cramps, it is always important to consult a healthcare professional before taking any supplements, as individual experiences may vary. Additionally, while creatine is generally considered safe for most people when taken by mouth, it is important to follow the recommended dosage guidelines to minimize the risk of any potential side effects.

Creatine may cause digestive issues
Creatine is a chemical found naturally in the body and is also present in red meat and seafood. It is often used to improve exercise performance and muscle mass. Creatine is likely safe for most people when taken by mouth. Lower doses of up to 4-5 grams daily for up to 18 months have been safely used. However, excessive doses may cause digestive issues.
A 2008 study found that a 5-gram dose of creatine taken twice daily caused diarrhoea in 29% of participants, which was similar to the placebo group. However, when the dose was increased to 10 grams taken once daily, the risk of diarrhoea increased significantly to 56%. This highlights the importance of adhering to the recommended serving size of 3 to 5 grams daily.
While creatine is generally considered safe, some people suggest that it may lead to digestive issues such as an upset stomach. However, it is important to note that these side effects are typically mild and comparable to those experienced by the placebo group in studies. Additionally, no evidence suggests that creatine causes digestive concerns when taken at recommended doses.
It is worth noting that creatine may interact with certain medications. Therefore, it is always best to consult a healthcare professional before taking creatine or any other supplement, especially if you have any health concerns or are taking medication. They can help you decide if creatine is suitable for you and advise you on the appropriate dosage.
