Can creatine really help with brain fog, working memory lapses, and the mental overload that comes with motherhood?

In this episode of the Wellness That Fits Podcast, registered dietitian and mom of three, Cassie Groeschl, breaks down the science behind creatine and cognitive function, especially for sleep-deprived, overwhelmed moms juggling work, family, and decision fatigue.

You’ve probably seen the headlines claiming creatine isn’t just for bodybuilders anymore. But what does the research actually say?

Cassie dives into:

• What creatine is and how it supports cellular energy (ATP) in the brain
• Who may benefit most from supplementation (vegetarians, older adults, and those under acute sleep stress)
• What studies show about working memory, processing speed, and executive function
• The emerging research on high-dose creatine during sleep deprivation
• The limitations and caveats you need to know before supplementing

Most importantly, she zooms out to answer the bigger question:
Is creatine the solution to chronic mom brain?

You’ll also learn what does have overwhelming scientific backing for cognitive resilience — including exercise, sleep quality, social engagement, and simple lifestyle shifts that fit into real life.

If you're tired, overstimulated, and wondering whether a supplement can fix your brain fog, this episode will give you clarity, nuance, and practical next steps.

Because wellness should fit your real life — not add more overwhelm.
