Your body makes creatine on its own and adjusts how much it makes based on how much energy your cells need, helping shuttle energy where it's needed most.

Evidence of an intracellular creatine-sensing mechanism that modulates creatine biosynthesis via AGAT expression in human HAP1 cells
The study shows cells can sense their own creatine levels and adjust how much they make, which helps balance energy use — just like the claim says.
The study shows that the body uses creatine like a battery shuttle to move energy where it's needed most, especially during activity, which supports the idea that it’s naturally regulated to keep energy flowing smoothly.

Mechanism of futile creatine cycling in thermogenesis.
The claim says creatine helps store and deliver energy where it's needed, like a battery. But the study shows that in fat cells, creatine actually burns energy as heat instead of saving it, which goes against the idea of it being a buffer.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
