Overview
Current evidence suggests that creatine is likely safe for use during pregnancy when taken at standard doses, but its routine supplementation is not yet established practice. The benefits of creatine in pregnancy may differ from those in non-pregnant adults, with emerging research indicating possible advantages for fetal development, especially in situations of oxygen deprivation or high metabolic stress. However, large human studies and clinical trials are still lacking, so recommendations are cautious.
Key Points
Safety of Creatine During Pregnancy
- Human Data: There are no large randomized controlled trials (RCTs) directly assessing creatine supplementation safety in pregnant women. However, reviews of creatine use in women of reproductive age and preterm infants have found no evidence of harm or serious side effects when supplements are produced to high standards and taken as directed. Pre-clinical (animal) studies and observational data in humans have not shown adverse effects on mothers or babies.Creatine Metabolism in Female Reproduction, Pregnancy and Newborn Health - PMCThe recently conducted Acceptability ... families and healthcare providers, concluding that creatine would be an acceptable supplementduringpregnancy provided they were given evidence-based assurances of efficacy and safety....Creatine and pregnancy: what you need to knowGiven the benefits for mother and baby, Dr Stacey Ellery and her team are investigating the optimal level of creatineduringpregnancy, including creatinesupplementation.

Summary
- Creatine is considered safe for women of reproductive age and has a strong safety profile in non-pregnant adults, but specialized safety studies in pregnant women are still needed.
- Animal and early human studies suggest creatine may benefit fetal and placental health, especially in pregnancies at risk for oxygen deprivation, but routine supplementation in pregnancy is not yet standard practice.
- The benefits of creatine in pregnancy are focused on fetal development and protection, not muscle or athletic performance.
- If you are considering creatine supplementation during pregnancy, it might be beneficial to discuss this with your OB/GYN or maternal-fetal medicine specialist, who can work with you based on your specific medical history and evolving research.Creatine Metabolism in Female Reproduction, Pregnancy and Newborn Health - PMCThe recently conducted Acceptability ... families and healthcare providers, concluding that creatine would be an acceptable supplementduringpregnancy provided they were given evidence-based assurances of efficacy and safety....Creatine and pregnancy: what you need to knowGiven the benefits for mother and baby, Dr Stacey Ellery and her team are investigating the optimal level of creatineduringpregnancy, including creatinesupplementation.
