Creatine and Cognition: A TikTok Doctor Discusses Promising Study

A recent TikTok video by Dr. Jennale, a family medicine physician, discusses a pilot study on creatine monohydrate and its potential cognitive benefits, particularly for older adults. The study, published in May 2025, found that supplementing with 20 grams of creatine daily showed improved cognition and recall in participants. However, Dr. Jennale cautions that the study was small and single-armed, meaning more research is needed to confirm the findings. "Take this with a grain of salt," she advises, emphasizing the need for larger, more comprehensive studies. The video also highlights the convenience of creatine gummies for patients who may struggle with traditional oral nutrition methods. While the results are promising, further research is crucial before drawing definitive conclusions about creatine's impact on cognitive function in Alzheimer's disease.
