Abstract

Aging is associated with decreased muscle function and cognitive processing. Current pharmacological andnutritional therapies to slow the progression of or reverse these effects have been unremarkable. Creatine is a natural component of the diet, and, as a dietary supplement, enhances fatigue resistance, increases strength, improves the performance of activities of daily living and may improve cognitive processing in older adults. These benefits also may augment the gains achieved during exercise training programs. Creatine supplementation appears to be a safe, effective, and inexpensive nutritional intervention that offers many benefits to aging individuals.
