Creatine Side Effects: Is It Safe? FAQs You Should Know

Creatine Side Effects


Creatine is a widely popular sports performance supplement known for its numerous benefits. However, there are concerns about its safety, causing some individuals to avoid it. In this article, we will explore the evidence-based facts regarding the safety and side effects of creatine.

Purported Side Effects of Creatine

Creatine has been associated with various claimed side effects, including kidney and liver damage, kidney stones, weight gain, bloating, dehydration, muscle cramps, digestive concerns, compartment syndrome, and rhabdomyolysis. However, extensive research supports the safety and effectiveness of creatine supplementation.

Debunking Myths: Is Creatine a Steroid?

Contrary to popular belief, creatine is not an anabolic steroid. It is considered extremely safe by the International Society of Sports Nutrition, and numerous studies have confirmed its positive effects. Creatine supplementation has been utilized for the treatment of various diseases and health conditions, including neuromuscular disorders, concussions, diabetes, and muscle loss.

Is Creatine Safe to Take Every Day?

Research has shown that daily consumption of creatine supplements over an extended period is safe. Even high doses of up to 30 grams per day for up to 5 years have not shown any significantly detrimental side effects. In fact, long-term supplementation has been associated with positive health benefits in athletes.

How Does Creatine Work Biologically?

Approximately 95% of creatine in the body is stored in the muscles. During high-intensity exercise, stored creatine helps muscles produce more energy, thereby enhancing exercise performance. Once muscle creatine stores are filled, any excess is broken down into creatinine and metabolized by the liver.

Debunking Dehydration and Cramps Myths

Contrary to popular belief, creatine does not cause dehydration or muscle cramps. Research has shown that creatine supplementation does not increase the risk of these conditions and may even offer some protection against them. In fact, athletes taking creatine have experienced fewer cases of dehydration, muscle cramps, or injuries during exercise.

Does Creatine Cause Weight Gain?

Creatine supplements have been proven to cause a temporary increase in body weight due to increased muscle growth, rather than an increase in body fat. Long-term studies have demonstrated greater weight gain in creatine users, which is beneficial for older adults, individuals with obesity, and certain medical conditions.

How Does Creatine Affect Kidneys and Liver?

Although creatine can raise levels of creatinine in the blood, which is commonly measured to diagnose kidney or liver conditions, it does not indicate harm to these organs. Extensive research conducted on healthy individuals and college athletes has found no adverse effects on kidney or liver function. However, individuals with pre-existing liver or kidney concerns should exercise caution and consult a healthcare professional before taking creatine.

Addressing Digestive Concerns

Excessive doses of creatine may cause digestive issues. However, when taken at recommended doses, creatine does not increase the risk of digestive concerns. Reports of such issues are often anecdotal, and no scientific evidence supports them. It is recommended to purchase high-quality, trusted products to minimize the risk of additives or contaminants.

Does Creatine Cause Acne?

There is no evidence to suggest that creatine directly causes acne. While increased sweating during exercise may lead to acne, creatine itself does not contribute to this condition. Some studies even suggest that creatine may improve skin health, reducing wrinkles and damage.

Drug Interactions and Other Effects

It is advisable to consult with a healthcare professional before starting any supplement regimen, including creatine. Certain medications that affect liver or kidney function may interact with creatine, and individuals using medication known.
