Creatine and the Brain: The Science Beyond the Gym

Most people think of creatine as a muscle supplement. But your brain is one of the most energy-hungry organs in your body, and creatine plays a role in how cells produce and recycle energy. That is why researchers have started paying close attention to creatine beyond the gym.

Everything below describes independent research about creatine and citicoline in general. It is educational, not medical advice, and not a claim about any product.

Creatine and the brain's energy supply

Creatine helps cells recycle ATP, the body's energy currency. Since the brain runs on that same energy system, scientists have explored whether topping up creatine could support brain function. Candow and colleagues, in a review titled "Heads Up" for Creatine Supplementation (Sports Medicine, 2023), describe creatine as playing a role in the optimal functioning of the human brain, and earlier work (Rawson & Venezia, Amino Acids, 2011) reported that supplementation may support short-term memory and reasoning in healthy adults.

Why this may matter more for women

As covered in our piece on creatine for women, women tend to carry lower natural creatine stores than men. Dolan and colleagues (Nutrients, 2023) have noted that women carry less brain creatine, which has led researchers to ask whether women might see a greater relative benefit.

Under stress: sleep deprivation

Some of the most striking findings come from stressed states. Research has examined how a single larger dose of creatine behaves during sleep deprivation, with studies reporting support for brain energy and cognitive performance when people are sleep-deprived. It is an emerging area, and the authors are careful to say more work is needed.

The other half: citicoline

Creatine is not the only nutrient tied to the brain's everyday housekeeping. Citicoline (CDP-choline) is a clean source of choline, and a clinical trial by McGlade and colleagues (2012) reported improvements in attentional performance and psychomotor speed in healthy adults after 28 days.

The honest caveat

This is a young and exciting field, not settled science. Reviewers consistently note that the brain research is promising but still needs more testing. What is clear is that creatine's story no longer ends at the gym door.
