Should women take creatine? What the science says

Creatine isn’t just for bodybuilders or male athletes. Research suggests it may help women support muscle and strength, particularly when combined with resistance training.

But creatine isn’t where we’d start.

A nutrient-dense diet with enough protein, together with regular strength training, provides the foundation for maintaining muscle, strength, and long-term health. Creatine monohydrate may offer an additional boost, particularly for women during and after menopause.

The strongest evidence is for muscle and strength. There is also emerging, but less certain, research into potential benefits for bone health, mood, and cognition.

This is general information, not medical advice. Talk with your doctor before taking creatine if you have kidney disease or are pregnant or breastfeeding.

Key takeaways

• Food and strength training come first. Creatine can be a useful addition, but it can’t replace the basics.
• Women can benefit from creatine, too, although women-specific research is still developing.
• The strongest evidence is for muscle and strength, particularly when creatine is combined with resistance training.
• Evidence for bone health, mood, and cognition is promising but still emerging.
• 3 to 5 grams of creatine monohydrate per day is a commonly studied maintenance dose.
• Meat and fish are the richest natural food sources of creatine.

What is creatine?

Creatine is a natural compound your body makes from three amino acids. Most of it is stored in your muscles, with smaller amounts found elsewhere in the body, including the brain.

Creatine helps regenerate adenosine triphosphate (ATP), which your cells use for quick bursts of energy, such as lifting a heavy weight, sprinting, or climbing a flight of stairs.

Your body makes creatine on its own. You also get it from food, primarily meat and fish.

Creatine supplements provide additional creatine beyond what you typically get from food alone.

Why may creatine be particularly relevant for women?

Women have historically been underrepresented in creatine research. We’re still learning how hormonal changes throughout life may affect creatine metabolism and response to supplementation.

Research suggests there are sex differences in creatine synthesis, dietary intake, metabolism, and utilization. Women also tend to consume less dietary creatine than men on average.

¹

This doesn’t necessarily mean women benefit more than men from supplementation. But it does mean we need more research that considers female physiology and different stages of life.

People who eat little or no meat or fish, including vegetarians and vegans, also tend to consume much less creatine from food.

What are the benefits of creatine for women?

Not every claim about creatine has the same level of scientific support. Here’s what we know so far.

Can creatine help women build muscle and strength?

This is where creatine has the clearest track record.

A 2026 systematic review and meta-analysis of seven randomized controlled trials involving 608 postmenopausal women found a small increase in lean mass and an improvement in leg press strength with creatine supplementation.

The benefits were most evident when at least 5 grams per day was combined with resistance training. Trials using 3 grams or less without resistance training did not show measurable benefits.

²

That last part matters.

Creatine isn’t a substitute for using your muscles. Think of it as something that may help you get more from strength training, while the training itself remains fundamental.

Is creatine good for bone health?

Possibly, but the evidence is less convincing.

Maintaining bone health becomes increasingly important as we age, particularly during and after menopause.

Creatine may support bone health indirectly by helping maintain muscle and physical function. However, the recent meta-analysis in postmenopausal women found no significant overall improvement in bone mineral density.

³

So while this is an interesting area of research, we wouldn’t currently recommend creatine primarily for improving bone density.

Can creatine support brain health, mood, or memory?

Your brain also uses creatine, which has led researchers to investigate whether supplementation could affect cognition, mental fatigue, and mood.

There are encouraging early findings, including research into cognition and depression. However, studies in women remain relatively limited, and the evidence is much less established than it is for muscle and exercise performance.

⁴

Think of these as possible additional benefits rather than reasons to expect a particular result from taking creatine.

Is creatine beneficial during menopause?

Menopause may be one of the most relevant stages of life for women to consider creatine.

As we age, maintaining muscle mass and strength becomes increasingly important for mobility, metabolic health, and independence.

Hormonal changes during and after menopause can also contribute to changes in body composition and bone health.

Research in postmenopausal women suggests creatine may provide modest additional benefits for lean mass and strength when paired with resistance training.

⁵

But the same hierarchy still applies:

Eat enough high quality protein. Strength train regularly. Then consider creatine as an optional addition.

If menopause is your focus, our 5-day menopause meal plan can help you build that nutritional foundation. It provides high protein, low carb meals designed to make healthy eating during menopause easier.

Will creatine make women bulky?

No. Creatine is not a hormone or steroid, and taking it won’t suddenly make you bulky.

Creatine may improve training performance and, when combined with resistance training, contribute to increases in muscle mass and strength.

Building substantial amounts of muscle requires consistent, progressive training over time.

Some people may also notice a small initial increase on the scale after starting creatine. This can be due to increased water stored in the muscles and isn’t the same as gaining body fat.

How much creatine should women take?

If you decide to supplement, you don’t need anything fancy.

Choose creatine monohydrate. It’s the most extensively studied form.

3 to 5 grams per day is a commonly studied maintenance dose.

For postmenopausal women interested in muscle and strength, recent evidence suggests that at least 5 grams per day combined with resistance training may be more effective than lower doses without training.

Consistency matters more than timing. Take it at whatever time of day makes it easiest to remember.

Loading is optional. A loading phase can increase muscle creatine stores faster, but it isn’t necessary for most people.

You can mix creatine with water or add it to coffee, a smoothie, or Greek yogurt.

⁶

Is creatine safe for women?

For healthy adults, creatine monohydrate has been extensively studied and is generally considered safe at commonly used doses.

One thing worth knowing is that creatine supplementation can cause a small increase in serum creatinine, a marker often used to estimate kidney function. This doesn’t necessarily indicate kidney damage.

A 2025 systematic review and meta-analysis found a modest increase in serum creatinine but no significant change in glomerular filtration rate (GFR).

⁷

If you take creatine, consider telling your healthcare provider so they can take this into account when interpreting your blood tests.

If you have kidney disease or are pregnant or breastfeeding, talk with your healthcare provider before taking creatine.

What foods are naturally high in creatine?

Before reaching for a supplement, remember that creatine is a naturally occurring nutrient in food.

The richest sources are animal foods, particularly meat and fish. Plant foods contain very little creatine, while eggs and dairy contain only small amounts.

Here are approximate amounts found naturally in some common foods:

Food	Approximate creatine per 100 g, raw
Herring	0.65 to 1 g
Pork	0.5 g
Beef	0.45 g
Salmon	0.45 g
Tuna	0.27 to 0.65 g
Chicken	0.3 to 0.4 g
Cod	0.3 to 0.44 g

⁸

These numbers are based on raw foods because cooking can reduce creatine levels. The amount lost varies depending on cooking method, temperature, and cooking time.

That doesn’t mean you need to start eating everything raw. But if you already enjoy raw or lightly cooked meat and fish, there are some delicious ways to get creatine naturally while avoiding or limiting heat-related losses.

Does raw fish contain more creatine than cooked fish?

Cooking can reduce the creatine content of meat and fish. Raw fish avoids these heat-related losses.

If you enjoy sashimi, raw salmon and tuna are delicious natural sources of creatine and high quality protein.

Fatty fish such as salmon offers another nutritional benefit: the long-chain omega-3 fatty acids EPA and DHA.

Rather than focusing on creatine alone, this is one of the advantages of getting nutrients from whole foods. Salmon provides protein, creatine, omega-3 fats, and other essential nutrients in the same meal.

Try one of our low carb sashimi recipes:

• Sashimi rolls
• Sashimi plate with wasabi mayo 
• Low carb sashimi salad with sriracha mayo 

Ceviche is another option since the fish isn’t exposed to heat.

What about creatine in beef?

Beef is another naturally rich source of creatine.

If you enjoy steak tartare, it provides beef without heat-related creatine losses. Try our Classic keto steak tartare.

Prefer your beef cooked? There’s no need to eat it raw just for the creatine. But if you already prefer steak rare or medium-rare, the center is exposed to less heat than in a well-done steak.

Our Perfectly seared steak includes instructions for rare, medium-rare, medium, and well-done steak.

We don’t have enough evidence to say exactly how much creatine is retained at each level of doneness, so we wouldn’t recommend choosing rare steak specifically for this reason.

A note on food safety

Raw or undercooked meat and fish can contain harmful bacteria or parasites.

Choose fish intended for raw consumption, buy meat and fish from trusted sources, and handle raw foods carefully.

If you’re pregnant or have a weakened immune system, follow your healthcare provider’s advice about avoiding raw or undercooked animal foods.

Should you get creatine from food or supplements?

At Diet Doctor, we believe food should come first.

Supplements can sometimes provide a useful extra boost, but they can’t replace a nutrient-dense diet, enough high quality protein, or regular movement and strength training.

Meat and seafood naturally provide creatine along with protein and many other essential nutrients.

That’s an important distinction. The goal of eating salmon, beef, or herring isn’t to reproduce a 3 to 5 gram dose of isolated creatine. Whole foods offer much more than any single nutrient.

Start by building your meals around nourishing whole foods and getting enough protein for your needs.

Then, if you want to support muscle and strength further, creatine is one evidence-based tool you may choose to add.

Think of it as an addition to the foundation, not the foundation itself.

Frequently asked questions

How much creatine should a woman take per day?

A commonly studied maintenance dose is 3 to 5 grams of creatine monohydrate per day.

For muscle and strength in postmenopausal women, recent evidence suggests that at least 5 grams per day combined with resistance training may provide greater benefit.

Will creatine make me gain weight?

Creatine may cause a small initial increase in body weight due to increased water stored in the muscles. This isn’t the same as gaining body fat.

When is the best time to take creatine?

For most people, consistency matters more than timing.

Pick a time that makes it easy to take regularly.

Do I need to take creatine on rest days?

If you choose to supplement, creatine is generally taken every day to maintain elevated muscle creatine stores, including on rest days.

Is creatine good for women during menopause?

It may be useful, particularly for postmenopausal women who also do resistance training.

The strongest current evidence is for modest improvements in lean mass and strength. Evidence for bone health, cognition, and mood is less certain.

The bottom line

Creatine is one of the most extensively studied sports supplements, and growing evidence suggests it may be useful for women, too.

But the basics matter more.

Prioritize protein-rich whole foods and regular strength training. Then, if you want an additional boost, creatine monohydrate is one option with a growing evidence base, particularly for supporting muscle and strength.
