Could Creatine Play a Role in Healthier Pregnancies?
Possibly. This review found that creatine metabolism is active in reproductive tissues, the placenta, and the developing fetus, with early research suggesting maternal creatine supplementation could help protect newborn brains from oxygen deprivation during birth.
Creatine is best known as a sports supplement, but it plays a much more fundamental role in the body than most people realize. Through a system called the creatine kinase circuit, creatine helps cells maintain their energy supply, especially cells with high or rapidly changing energy demands. The female reproductive system, the placenta, and the developing fetus all have significant energy needs, which makes creatine metabolism a relevant topic for pregnancy research. This review from the journal Nutrients gathered the available evidence on how creatine functions in reproduction, pregnancy, and early newborn life.
Dr Kumar’s Take
This is a fascinating area of research that most people would never associate with creatine. The idea that a mother’s creatine status during pregnancy could affect her baby’s outcomes is really thought-provoking. What caught my attention is the evidence linking problems with creatine metabolism to reduced fertility and poor pregnancy outcomes. That suggests creatine is not just a nice-to-have for pregnant women, it may actually be important for healthy reproduction. The most exciting potential application is using maternal creatine supplementation to protect newborn brains from oxygen deprivation during birth, which is one of the leading causes of neonatal brain injury. The caveat is that most of this evidence comes from preclinical studies and small animal models, so we still need human clinical trials to confirm these findings.
What the Research Shows
The review consolidated evidence showing that creatine metabolism is active throughout the female reproductive system. The creatine kinase circuit, which converts creatine into usable energy in the form of adenosine triphosphate (ATP), is particularly important for cells that have high or rapidly fluctuating energy demands. This includes cells in the reproductive organs, the placenta, and the growing fetus.
Some studies have linked disruptions in creatine metabolism to reduced fertility and poor pregnancy outcomes. This suggests that maintaining adequate creatine levels may be important for successful reproduction, though the evidence is not yet strong enough to say creatine is essential for this process.
Potential for Brain Protection in Newborns
The most compelling area covered in this review is the use of maternal creatine supplementation during pregnancy as a way to protect the newborn brain against injuries caused by oxygen deprivation during birth. This type of injury, known as hypoxic-ischemic brain injury, is a leading cause of disability in newborns. The idea is that if the baby has higher creatine stores at the time of birth, their brain cells may be better equipped to survive periods of low oxygen.
This concept has been widely studied in preclinical laboratory models and small animal studies. The results have been encouraging enough to spark interest in human research. However, the review authors emphasized that there is still no consensus on whether creatine is truly essential for successful reproduction, and they highlighted significant knowledge gaps that need to be addressed before clinical recommendations can be made.
Practical Takeaways
- Creatine metabolism is active in the female reproductive system, the placenta, and the developing fetus, suggesting it plays a role in pregnancy health beyond what most people realize.
- Some research has linked problems with creatine metabolism to reduced fertility and poor pregnancy outcomes, though more evidence is needed.
- Maternal creatine supplementation shows promise for protecting newborn brains from oxygen deprivation injuries during birth, but this has mainly been studied in animal models so far.
- Pregnant women should not start creatine supplementation based on this evidence alone. Talk to your obstetrician about the current state of the research and whether it might be relevant to your situation.

FAQs
Is it safe to take creatine during pregnancy?
There is not enough human research to make a definitive recommendation about creatine supplementation during pregnancy. The preclinical evidence is promising, but human clinical trials are still needed. Any decision about supplementation during pregnancy should be made in consultation with your healthcare provider.
How does creatine protect a newborn’s brain?
The theory is that higher creatine stores in the newborn brain would help brain cells maintain their energy supply during periods of low oxygen, which can occur during complicated deliveries. By keeping cellular energy levels stable, creatine may help prevent or reduce the severity of brain damage. This has been demonstrated in animal models but needs human confirmation.
Does creatine affect fertility?
Some studies have found links between disruptions in creatine metabolism and reduced fertility, but the evidence is not conclusive. The relationship between creatine and fertility is still being studied, and more research is needed before any clinical recommendations can be made. Creatine’s role in cellular energy supply suggests it could be relevant to the energy-demanding process of reproduction.
Bottom Line
Creatine metabolism appears to play a meaningful role in female reproduction, pregnancy, and newborn health. The most exciting potential application is protecting newborn brains from oxygen deprivation during birth, though human clinical trials are still needed to confirm the promising preclinical findings.
