Should women over 40 take Creatine?

Short answer?

Yes most women over 40 who strength train could benefit from it.

I hesitated for a long time, as well as protein powders. It felt unnecessary. But it’s one of the most researched sports supplements available, and the research is clear:

What creatine actually does

Creatine helps your body produce energy during short, high-intensity efforts like:

• Lifting weights

• Sprinting

• Intervals

• Explosive movements

Why it’s relevant after 40

From our 30s onwards, we naturally lose muscle mass. For women in their 40s, especially approaching perimenopause, this becomes more significant.

Muscle isn’t just about how you look. It affects metabolism, bone health, injury risk, balance and independence later in life. Creatine supports your ability to train hard enough to maintain that muscle.

Key benefits for women over 40

1. Supports muscle retention
Helps you build and preserve lean muscle when combined with strength training.

2. Improves strength & power
Power declines faster than strength with age. Creatine supports explosive efforts and repeated performance.

3. May support bone health
When paired with resistance training, it may help improve bone density, crucial for women over 40.

4. Cognitive support
Creatine is also stored in the brain. Some research suggests it may help with mental fatigue and cognitive function.

Let’s bust the myths

“It makes you bulky.”
No. You don’t accidentally gain large amounts of muscle. It may increase water inside muscle cells, making them look slightly fuller.

“It causes bloating.”
Most women tolerate 3–5g daily very well. You don’t need a loading phase.

“It’s unsafe.”
In healthy individuals with normal kidney function, creatine is widely considered safe at recommended doses.

Why I started taking it

I train seriously, I care about muscle retention, I want to be strong now, and at 70.
