Is it now appropriate to assert that creatine supplementation holds cognitive benefits for the elderly?

Abstract

This paper explores the potential cognitive benefits of creatine supplementation for the elderly population. Creatine, known for its role in muscular and neuronal energy metabolism, is primarily obtained through dietary intake, particularly from meat sources. The literature underscores creatine's significance in neural tissue development and cognitive capacity, with deficiencies linked to impaired cognitive function, especially in infants. In the context of the aging global population, cognitive decline is a prevalent concern, and reduced creatine concentration is implicated in this process. While association studies suggest a connection between creatine intake and cognitive performance in the elderly, the absence of robust clinical trials calls for further investigation. Physiological plausibility supports the idea that increased creatine intake, combined with physical activities, could positively impact cognition in the elderly. However, the existing evidence remains inconclusive, and rigorous randomized placebo-controlled clinical trials are essential to establish a cause-and-effect relationship and elucidate underlying mechanisms. Confirmation of cognitive benefits could pave the way for determining optimal dosages to enhance cognitive function in the elderly.
