Creatine supplements are everywhere lately. What started as a staple in gym culture has gone mainstream — marketed to women for muscle tone, energy, and even cognitive performance. If you have endometriosis, you may have wondered whether it’s safe to take.
Some emerging research suggests that the relationship between creatine and endometriosis is worth understanding before incorporating it into your routine.
At Solace Women’s Care in Conroe, Texas, Farly Sejour, MD, FACOG, and Natalie Gould, WHNP-BC, along with our team, help women navigate questions like this one — where health trends and gynecological conditions intersect.
Your body already makes creatine. It’s produced naturally in the liver and kidneys and stored in muscle tissue, where it helps fuel short bursts of physical activity. You also get small amounts from food like:
Supplemental creatine — usually taken as creatine monohydrate powder — simply raises those levels higher than food and natural production alone can achieve. For healthy adults without underlying conditions, it’s generally considered safe.
Endometriosis happens when tissue resembling the uterine lining takes root outside the uterus, most often in the pelvis. It’s more common than many people realize, affecting an estimated 190 million women worldwide. Symptoms vary widely but often include:
The condition tends to be underdiagnosed because symptoms overlap with other issues and can be dismissed as normal period pain. Many women live with endometriosis for years before getting answers.
Researchers have found that creatine tends to accumulate in the pelvic environment of women with endometriosis at higher concentrations than in women without the condition. That accumulation appears to help displaced endometrial cells survive and spread in ways they wouldn’t know otherwise.
Endometriosis progresses partly because cells that travel outside the uterus can take hold somewhere new. The body has natural mechanisms to prevent that from happening, but creatine seems to interfere with at least one of them. It may also influence how immune cells in the abdominal cavity behave, nudging them toward responses that encourage:
None of this means creatine supplements directly cause endometriosis.
Should you stop taking creatine if you have endometriosis?
There’s no clinical guideline telling women with endometriosis to avoid creatine. What science suggests is that creatine plays a more active role in the disease than previously understood, making it reasonable to discuss with our team.
If you take creatine regularly and have endometriosis, bring it up at your next visit. A few things worth mentioning:
Your care team can help you weigh your options based on your specific situation.
Managing endometriosis means staying informed about all things that affect your body, including any supplements you’re taking. At Solace Women’s Care, we take the time to understand your full health picture before making recommendations.
