Creatinine: Promise for Muscles and Memory

Creatine isn’t just for bodybuilders anymore. In this episode, we break down what creatine actually does in the body — and why researchers are now studying it for brain health, muscle preservation, and healthy aging. You’ll hear about typical dosing (3–5 grams daily), what we know about safety, and what the latest research shows in older adults — including a small pilot study in Alzheimer’s patients using higher doses that increased brain creatine levels by about 10%. But does that mean everyone should take it? Not so fast. We’ll walk through who might benefit, who should be cautious, and how to think about supplementation through a lifestyle medicine lens. If you’re navigating midlife changes, muscle loss, brain fog, or just trying to age with strength and clarity, this episode will help you make an informed decision. Because supplements should support a healthy foundation — not replace one. Resources: Keep Your Brain Sharp Get every episode in your inbox Browse more episodes
