Mechanism of Interaction

Older research suggested caffeine might blunt creatine uptake in skeletal muscle by opposing its ergogenic effects on phosphocreatine resynthesis. More recent meta-analyses have not confirmed this interaction at physiological doses. Caffeine does not significantly impair creatine's cognitive benefits (phosphocreatine supports brain energy metabolism). For brain health and cognitive use cases, these are generally considered safe to combine.

Recommendation

Combine freely for cognitive use cases. If using primarily for athletic performance, some coaches prefer separating caffeine and creatine intake timing, though current evidence does not strongly support this concern.
