Creatine: A Powerful Ally for Women’s Health

When you think of creatine, you might picture bodybuilders or athletes chugging powdery drinks at the gym. But creatine is so much more than a fitness supplement, especially for women. It’s one of the most well-researched nutrients for supporting energy, cognition, strength, mood, and even hormonal transitions throughout a woman’s life.

Let’s dig into why creatine may be worth considering as part of your foundational supplement routine.

What is Creatine, and Why Does It Matter?

Creatine is a compound your body makes naturally from amino acids, and it's also found in animal-based foods like meat and fish. It plays a critical role in cellular energy production, especially in high-demand tissues like the brain, heart, and muscles. Think of it as fuel for your mitochondria, helping your cells make ATP (your body’s energy currency) more efficiently.

While our bodies produce a small amount of creatine daily, many women — especially those eating plant-based or lighter animal protein diets — don’t get enough through food alone.

The Female Creatine Gap

Women store significantly less creatine than men, both in muscles and in the brain. That means we’re often starting at a disadvantage when it comes to strength, cognitive stamina, and even mood regulation. Studies suggest that 70% of women aren’t meeting the recommended creatine intake, and that number only worsens with age.

Hormonal fluctuations also impact how we synthesize and store creatine. Estrogen and progesterone levels influence creatine metabolism, making supplementation particularly important during times of hormonal change: – Puberty and menstruation – Pregnancy and postpartum – Perimenopause and menopause

Creatine Through the Female Lifespan

During the Menstruating Years:

Creatine needs rise in the second half of your cycle (the luteal phase), when estrogen peaks and your body breaks down protein more rapidly. Supplementing during this time may help with energy dips, strength maintenance, and even mood swings tied to your cycle.

Pregnancy & Reproductive Health:

Emerging research links creatine with fetal development and better pregnancy outcomes. It’s used by both sperm and egg during fertilization, and low creatine levels in pregnancy may contribute to low birth weight or preterm birth. While more research is needed, it’s an exciting area to watch — and a discussion worth having with your healthcare provider.

Menopause & Postmenopause:

As estrogen drops, many women notice declines in muscle mass, strength, bone density, and energy. Creatine has been shown to help preserve lean tissue, reduce inflammation, support cognition, and even improve outcomes when paired with resistance training. For

Creatine for the Brain

Women’s brains store less creatine in areas that regulate emotion, memory, and cognition. Low phosphocreatine levels may contribute to fatigue and brain fog — especially during hormonal transitions or times of stress. Creatine supplementation has been shown to reduce mental fatigue and support better focus, particularly during sleep deprivation or stress.

How Much Creatine Do Women Need?

Research shows that women may need slightly more creatine than men to reach saturation, due to lower baseline storage and hormonal influence on metabolism. Here's a general guide:

• Daily maintenance dose: ~3–5 grams per day (about 0.03g per pound of body weight)

• Loading phase (optional): 5 grams 4x/day for 5 days for faster saturation

• Brain saturation: 15–20 grams/day for 3–7 days, then 5–10 grams/day maintenance

Consistency is key — stores begin to deplete within days if supplementation stops.

What Kind of Creatine is Best?

Creatine monohydrate is the gold standard — it’s the most researched and consistently shown to be effective, safe, and well-tolerated.

I personally like Thorne’s Creatine because it’s clean, unflavored, and easily mixes into your daily routine. You can use it solo or blend it with other powders, before or after workouts, or whenever it fits your schedule.

Add Creatine to Your Routine

Bottom Line

Creatine isn’t just for athletes. It’s a clinically proven, well-tolerated tool that can support women’s health across all life stages — from hormone regulation and brain health to strength and longevity.

If you’re navigating hormonal transitions, struggling with energy or brain fog, or working to optimize your body composition, creatine might be one of the simplest yet most impactful additions to your toolkit.

As always, reach out if you'd like help personalizing your supplement strategy or have questions about what’s right for your current life phase.
