Creatine: From Gym to Cognition

Creatine is a supplement that has long been associated with athletic performance, mainly beneficial for increasing muscle mass and strength. However, recent studies are illuminating its potential as a cognitive enhancer. During the ABC7 segment aired on January 26, 2025, Dr. Lalezari explained how creatine functions in the brain, enhancing energy availability and potentially supporting neuron health.

He remarked, "When most people think of creatine, they think of the gym and building muscle, but the science is showing us that it does much more than that. Creatine helps increase energy in the brain and may also support and protect neurons."

Cognitive Enhancements and Neuroprotection

Research indicates that creatine may improve cognitive performance, especially during challenging circumstances such as sleep deprivation, aging, and the postpartum transition. Dr. Lalezari's insights emphasize that creatine could be beneficial even outside its traditional scope of physical performance. The medical community is increasingly considering creatine as a supplement not just for athletes but for the general population seeking to enhance cognitive function.

Safety and Accessibility

While creatine is generally considered safe for most adults, Dr. Lalezari advises individuals with pre-existing kidney conditions to consult with their healthcare provider before beginning any supplementation. Moreover, the segment highlighted the accessibility of creatine, as it is widely available and affordable which facilitates its uptake by everyday consumers.
