Many new moms want to take care of their bodies and feel their best, both physically and mentally. Creatine is a popular supplement known for supporting muscle strength, recovery, and even brain energy. It works mainly by supporting the body’s production of ATP, which is the main energy source for your muscles and brain. But if you are breastfeeding, you might wonder: is creatine safe while nursing, and what does science actually say about creatine and breastfeeding?
This article will walk you through the latest research, what scientists do and do not know, and practical tips for postpartum moms. By the end, you will feel better prepared to make an informed decision for yourself and your baby.
Is Creatine Safe While Breastfeeding?
What Do We Know Right Now?
There is very little research on using creatine supplements while breastfeeding. Most of what is known comes from how the body normally uses creatine, plus a few small human studies measuring natural levels in breast milk. Because of this, no major medical organizations have called creatine either definitely safe or unsafe for nursing mothers.
Theoretical Concerns and Considerations
Experts say creatine might pass into breast milk in very small amounts. The effect this has on nursing infants is not totally clear. Theoretical risks could include possible changes in infant kidney function, but there is no solid evidence of harm from creatine supplements at typical doses during breastfeeding.
What Do Health Professionals Advise?
Most doctors recommend using caution with any supplement while breastfeeding, including creatine. If you are considering taking creatine, it is always best to consult with a knowledgeable healthcare provider who can look at your unique health situation.
What Research Says About Creatine in Breast Milk
What Studies Have Found
Scientific studies on creatine and breastfeeding are limited. Researchers have measured average creatine levels in breast milk at about 10.5 mg/L in North American and European populations. Levels are highest in colostrum and decrease over the first two weeks postpartum before stabilizing. However, milk levels have not been measured after supplementation in humans. These studies confirm that breast milk naturally contains a small amount of creatine.
Small Human Studies
So far, very few studies have looked specifically at the effects of creatine supplements in breastfeeding mothers. There are small animal studies and a handful of observational studies in humans, but no large clinical trials.
Animal Research Insights
Animal studies suggest extra creatine intake might support the developing brain and muscles in newborns, but it is still not known if this holds true in humans. Overall, more research is needed before clear recommendations can be made.
Why There Is Limited Research on Creatine and Breastfeeding
There are not many studies on creatine and breastfeeding because most supplement research focuses on athletes and healthy adults, not nursing moms. Studying pregnant and breastfeeding women is also more complicated, since researchers need to put the safety of both mom and baby first. Because of these challenges, information about creatine and breastfeeding is based on smaller studies, animal research, and what we know about how creatine works in the body.
What We Still Don’t Know About Creatine and Breastfeeding
Researchers still do not fully understand how creatine supplements might affect the long-term health of infants who receive breast milk from mothers taking creatine. It is also unknown if taking extra creatine would provide any clear benefits or risks for postpartum women. Because so many questions remain, most experts recommend caution until more studies are done.
Is Creatine Naturally Found in Breast Milk?
Yes, creatine is naturally present in human breast milk. According to a study published by the National Library of Medicine, breast milk provides about 9 percent of an infant's daily creatine needs. The amount of creatine in milk can vary by country, diet, and other factors. This natural presence helps support a baby’s growth and brain development during early life.
How to Choose the Right Creatine Supplement
Creatine Monohydrate vs. Blends
Creatine monohydrate is the most studied and widely used form of creatine. Combination blends or newer forms may not be as well tested, especially for safety during breastfeeding. Choosing a basic, pure creatine monohydrate supplement may offer more peace of mind.
Purity Testing and Quality
Look for supplements that have been independently tested for purity and quality. Third-party testing from organizations like NSF or USP may help reduce the risk of contaminants that could pass into breast milk.
How Much to Take
Standard doses are usually around 3 to 5 grams per day. Some brands offer larger “loading” doses, but these are not necessary for most people. If you are breastfeeding and choose to use creatine, stick to the lowest effective dose and discuss it with your healthcare provider first.
Can Creatine Support Postpartum Energy?
Creatine is best known for helping muscles recover after exercise. There is also some early evidence that it might support brain energy and mental function. Some women feel more tired after pregnancy and birth, so they wonder if creatine and breastfeeding could help with that fatigue. However, these benefits are not proven in nursing mothers, and energy levels depend on many different factors. It is important to address basics like rest and nutrition first.
Safer Alternatives to Support Postpartum Energy
Prioritize Sleep When Possible: Quality sleep is essential for recovery and overall energy. Rest when your baby naps if possible, and ask for help from family or friends.
Stay Well Hydrated: Drinking plenty of water helps support milk production and keeps your energy up throughout the day.
Check Iron and Other Nutrients: Iron deficiency is common after childbirth and can cause fatigue. Ask your doctor about having your iron and other nutrient levels checked.
Eat Balanced, Frequent Meals: Include healthy proteins, whole grains, fruits, and vegetables to help keep your energy steady all day long.
Gentle Movement: Light walks or stretching can help boost your mood and energy, even if you are tired.
Connect with Support: Emotional support and talking with other new parents can ease stress, which may also help with energy levels.
When to Talk to Your Doctor
If you are interested in taking any supplement while breastfeeding, especially creatine, bring it up with your healthcare provider first. They can help you weigh the risks and benefits based on your health, medical history, and baby’s needs. It is smart to check in if you notice new symptoms like fatigue that will not go away, changes in your milk supply, or if you have questions about your diet or supplementation.
Taking care of yourself during the postpartum period is important for both you and your baby. While there is still a lot we do not know about creatine and breastfeeding, focusing on healthy sleep, balanced meals, and communication with your doctor can help you feel your best.
Frequently Asked Questions (FAQ)
What supplements should I avoid while breastfeeding?
Some supplements can pass into breast milk or affect your milk supply. Talk to your doctor before using herbal products, high doses of vitamins, weight loss aids, or anything containing caffeine or stimulants.
Who should avoid creatine?
People with kidney problems or a history of kidney disease should avoid creatine. Always consult your doctor before starting any new supplement, especially if you are breastfeeding or have medical conditions.

The most common side effect is water retention, which might cause mild weight gain or digestive discomfort in some people. Rarely, higher doses can stress the kidneys.
Does creatine reduce lactate?
In athletes, creatine may help reduce how much lactate builds up in muscles after hard exercise. There is not enough research to know if this matters for breastfeeding moms.
Does creatine reduce fatigue?
Creatine may support energy in muscles and the brain, but results vary from person to person. It has not been studied specifically for reducing postpartum fatigue in nursing mothers.
Does creatine reduce hormones?
Current research does not show that creatine significantly lowers hormone levels. More study is needed, especially in breastfeeding women.
