What Happened When I Started Taking Creatine at 40

I didn’t expect much to change when I turned 40, and at first, I was right — until I wasn’t. About six months after the big 4-0, I started to feel just a little bit … off. I was suddenly yawning a lot more in the afternoon. My brows and lashes, which had always been rather full, began to get patchy. And I kept having these brain blips, as I like to call them. I’d be in the middle of telling a story, and then I’d get stuck trying to remember a name or a basic word. While none of that was fun, the most unfun change of all was a noticeable difference in what I could lift.
I’m a regular weight trainer; it’s a big part of what got me back in shape after gaining 20 pounds during the pandemic. I practice progressive overload — gradually upping how much you lift to keep achieving those sweet, sweet muscle gains. However, one day, the weights I’d been using for shoulder presses suddenly felt much heavier. I quickly did some research and realized it could be muscle loss due to perimenopause. When I asked a registered dietitian if there was anything I could do to mitigate that, she pointed me to creatine.
It’s generally recommended to start taking 3 to 5 grams (g) of creatine monohydrate a day, which is what I did (but always check with your healthcare provider first). I went with this creatine monohydrate micronized powder by Orgain because it had good reviews and was relatively affordable.

I loved how easy this creatine powder was to incorporate into my life. It dissolves in water within 30 to 60 seconds and has no real taste. I typically take it right before or right after a workout, but there’s really no better or worse time. “Consistently taking creatine is more important than when you take it,” says Kitchens. “Research shows that taking creatine post workout may be advantageous for body composition, but again, consistency is what’s key.”
Within about a month of consistently taking creatine, I started to feel stronger. Slowly but surely, I was able to lift heavier again. I also had more stamina, so I started doing longer, more intense workouts. Beyond that, my energy stayed high throughout the day, and I just generally felt better. Even my brain fog started lifting.
It seemed magical, but there’s a real scientific reason for the results I was seeing. “Women have 70 to 80 percent lower baseline creatine stores than men, due to lower creatine production and intake,” says Avery Zanker, RD, practicing with Health Casa in Ontario, Canada. “This can make the benefits of creatine more noticeable for women. Creatine production and metabolism are impacted by sex hormones like estrogen and progesterone in ways that suggest that creatine may be particularly influential during menstruation, postpartum, perimenopause, and postmenopause.”
