Although generally considered safe, creatine is not suitable for all situations. Some women should consult a healthcare professional before using it, especially:

• Those with kidney failure: creatine is metabolized by the kidneys, and medical monitoring is recommended if you have a history of kidney problems.

• Pregnant or breastfeeding women: as a precaution, due to a lack of sufficient studies in these populations, it is advisable not to take creatine without medical advice.
