From gym bros to new mums: why scientists are rethinking creatine as a women’s health booster

From pregnancy to postpartum and even menopause, creatine could be a secret weapon for women’s health, though big question marks remain for breastfeeding.

Creatine might sound like something only weightlifters care about. But scientists are starting to see it in a whole new light. From fuelling labour to speeding postpartum recovery, this everyday supplement could be the next big thing for mums.

So, should you be adding creatine to your smoothie? Here’s what the research says, and where the gaps still lie.

What is creatine, and why women have less of it

Creatine is a compound your body makes naturally and also gets from foods like meat and fish. It helps your muscles and brain generate quick bursts of energy, which is why athletes swear by it.

But here’s the surprise: women have up to 70–80% lower creatine levels than men. Those levels dip even further at stressful times like pregnancy, new motherhood and menopause.

Pregnancy: could creatine protect babies in labour?

Research suggests creatine fuels the uterus, placenta and even the developing baby. Levels drop in the first half of pregnancy, when demands are highest.

Animal studies show that topping up with creatine might protect babies from oxygen deprivation during labour, a complication linked to developmental delays and neurological issues.

Creatine is the fuel for the ‘backup energy battery’ of many vital cells in the brain… Much like folate, creatine could one day be a standard pregnancy supplement to protect babies.

The catch? Human trials are still in planning. For now, the science is promising but not proven.

Postpartum: recovery, mood and healing

After birth, creatine could help mums rebuild strength and resilience. Early studies suggest it may:

Support brain health: easing fatigue and brain fog from sleep deprivation
Boost mood: studies link creatine to reduced symptoms of depression, with potential for postpartum support
Aid healing: helping with inflammation, muscle recovery, and wound repair after C-sections or perineal trauma

Creatine isn’t just for bodybuilders, it’s a scientifically backed supplement that accelerates recovery, supports your brain, and helps rebuild your body from the inside out.

Breastfeeding: the unanswered questions

This is where things get complicated. Creatine is naturally present in breastmilk, especially in colostrum (the first milk after birth). Scientists believe it helps fuel babies’ developing brains.

But what happens if mums supplement? Right now, no one knows.

Concerns include:

Babies’ immature kidneys may not cope with extra creatine
Milk quality or supply could be affected
Side effects like water retention in mums could slow recovery

Until more data are available, it is probably best to avoid creatine supplementation unless prescribed by a healthcare professional.

The bottom line: if you’re breastfeeding, experts advise against creatine until we know more.

Menopause: strength and bone protection

Later in life, creatine could help again. After menopause, when oestrogen levels fall, women are more at risk of osteoporosis and muscle loss. Studies show creatine, especially when combined with resistance training, can help preserve bone density and increase muscle mass, lowering the risk of falls.

How much is safe, and when to avoid it

For most adults, 3–5g a day of creatine monohydrate is considered safe and effective. But safety hasn’t been confirmed in pregnancy or breastfeeding, so always check with your GP, midwife or paediatrician before starting supplements.

Remember: creatine pulls water into cells, so staying hydrated is vital (pale straw-coloured wee is your guide).

The takeaway for mums

Creatine is shaping up as one of the most exciting supplements in women’s health, with potential benefits across pregnancy, postpartum and healthy ageing.

But when it comes to breastfeeding, the science just isn’t there yet. The safest option? Wait until your nursing journey is over before adding creatine to your routine.
