Creatine supplementation exacerbates the hepatic toxic effects of ethanol. Creatine intake associated with ethanol upregulates ethanol metabolism genes. Creatine supplementation exacerbates ethanol-induced oxidative liver damage. Creatine associated with ethanol intake upregulates inflammation-related genes.
Dietary exposure to creatine through a regular diet is not associated with more liver disease manifestations in U.S. population aged 12 years and over. The risk of having liver fibrosis, cirrhosis, and hepatic steatosis is similar between low‐intake and high‐intake creatine consumers.
Studies have found that Cr supplementation can increase skeletal muscle and brain total Cr and PCr concentrations, with an even greater degree of increase seen in organs with low baseline creatine content such as kidney and liver (Ipsiroglu et al., 2001) but the possible side effects of Cr supplementation, such as ...
People with pre-existing kidney disease, liver problems, diabetes, or bipolar disorder, as well as pregnant or breastfeeding women, should avoid creatine or consult a doctor first, as it can worsen conditions or have unknown effects, especially when combined with certain medications or excessive caffeine. It's crucial to talk to a healthcare provider before starting, as creatine can affect kidney-related lab results.
While creatine is considered a safe and well-researched supplement, it does come with potential side effects. 1 When taking more than the recommended 3 to 5 grams a day—such as during the loading phase—you may experience stomach upset, water retention, and slight weight gain.
Boosting Your Energy
Otherwise, an adult dose of 3 to 5 grams of creatine daily is safe. However, people with kidney disease should consult with their doctor prior to taking it. Creatine is not an anabolic steroid, nor does it increase testosterone levels.
What are the symptoms of high creatinine levels?
👉 Bottom line: Current evidence shows creatine does not cause hair loss in healthy people without genetic predisposition.
Doctors don't universally discourage creatine but recommend caution due to unknowns, especially long-term effects, potential interactions (caffeine, certain meds), and risks for those with pre-existing conditions like kidney issues or bipolar disorder; most concerns center on lack of research in kids/pregnant women and potential side effects like water retention, though it's generally safe for healthy adults at recommended doses.
Creatine is a relatively safe supplement. However, side effects may include: Weight gain because of water retention. Dizziness.
Gaining 10 pounds on creatine is common and usually due to water retention in muscles and increased muscle mass, not fat; creatine pulls water into your cells, causing temporary fullness, while also boosting performance for real muscle growth. This initial weight gain (often 3-8 lbs) is normal, doesn't mean fat gain, and typically stabilizes, though the increased muscle and water contribute to the number on the scale.
Creatine is a compound that your body naturally makes, and you also get it from protein-rich foods. It supplies energy to your muscles and may also promote brain health. Many people take creatine supplements to increase strength, improve performance and help keep their minds sharp.
In short, creatine can be associated with mild digestive problems such as bloating, stomach ache or diarrhoea. Note that these side effects are rare, temporary and avoidable, provided you follow a suitable protocol. They often occur at the start of a course of treatment, during the so-called "loading" period.
In addition, there has been no evidence that creatine supplementation promotes muscle cramping among athletes.
Nausea and Diarrhea
Nausea is likely caused by the large amount of water and creatine ingested, while diarrhea is likely caused by creatine pulling water into your intestines.
Boosting Your Energy
Otherwise, an adult dose of 3 to 5 grams of creatine daily is safe. However, people with kidney disease should consult with their doctor prior to taking it. Creatine is not an anabolic steroid, nor does it increase testosterone levels.

Creatine works by pulling water into your muscle cells, enhancing energy metabolism and performance. But without proper hydration, you risk minimizing those benefits or worse, dealing with discomfort like bloating, cramps, or fatigue.
6. Liver Enzyme Elevations (Uncommon) That said, people with existing liver conditions or those taking other liver-metabolized medications should consult a healthcare provider before using creatine. Routine monitoring of liver enzymes may be advised if creatine use is prolonged.
5 Tips to Follow If Creatine Is Making You Bloated
Negative changes in mood or anxiety following supplementation with creatine have been documented in two human trials (Roitman et al., 2007; Volek et al., 2000) and one animal experiment (Allen et al., 2010).
To maximise results with creatine, cycling is recommended. Remember to have a break between cycles and increase daily water intake when using creatine.
Creatine Side Effects
These include symptoms such as nausea, vomiting, diarrhea, bloating, and indigestion. However, after comparing the side effects of study participants who received a placebo instead, the study authors found no evidence that creatine supplements have a significant effect on GI symptoms.
Creatine is possibly safe when taken long-term. Doses up to 10 grams daily for up to 5 years have been safely used. Side effects might include dehydration, upset stomach, and muscle cramps. When applied to the skin: There isn't enough reliable information to know if creatine is safe.
