The influence of creatine supplementation on the cognitive functioning of vegetarians and omnivores

What the study found

This trial tested whether diet changes creatine's cognitive effect. Vegetarians — who get little dietary creatine — improved on a memory task after supplementation, while omnivores did not, supporting the idea that people with lower baseline stores respond most.

Key findings

• Vegetarians showed improved memory performance after supplementation.
• Omnivores showed no significant cognitive change.
• Baseline creatine status appears to predict who benefits cognitively.

The practical takeaway

If you eat little or no meat, creatine is likely to do more for your brain than for a heavy meat-eater's.
