What the research says
2 studies reviewedSupporting (2)
Cohort StudyHuman2024
This study shows that a protein related to creatine use helps colorectal cancer grow, but it doesn't prove that tumors from other cancers use creatine as fuel.
Cross-Sectional StudyAnimal2025
This study shows that liver cancer cells use creatine to grow and survive, supporting the idea for liver cancer, but it didn't test other cancers like pancreatic, colon, or breast, so the claim that all those cancers use creatine goes beyond the evidence.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Cancer cells in low-oxygen areas take in creatine from their surroundings. Inside the cell, creatine switches on a chain of proteins that ultimately stabilizes a key enzyme, PKLR. This enzyme changes how the cell uses energy, protecting the cancer cell from a specific type of cell death called parthanatos. By escaping death, the cancer cells survive and grow, fueling tumor progression.

Tumors from several cancers (liver, pancreatic, colon, breast) use creatine as an energy source to grow and spread.
Mechanism
3 studiesIn liver cancer, low-oxygen conditions make cancer cells import creatine, which triggers a protective chain that prevents the cells from dying. This allows the tumor to grow. On the other hand, immune cells also use creatine to become stronger and attack tumors. The cancer-promoting effect of creatine directly supports the claim that tumors use creatine to grow.

This enzyme changes how the cell uses energy, protecting the cancer cell from a specific type of cell death called parthanatos. By escaping death, the cancer cells survive and grow, fueling tumor progression.
Hypoxia induces expression of the creatine transporter SLC6A8 on cancer cells, increasing creatine uptake and intracellular creatine levels.
Accumulated creatine activates MPS1 kinase, which phosphorylates Smad2/3 transcription factors, driving expression of SERPINE1.
SERPINE1 and HIF1α form a positive feedback loop, mutually reinforcing each other's expression under hypoxia.
SERPINE1 binds to USP10 and PKLR, forming a complex that promotes USP10-mediated deubiquitination and stabilization of PKLR.
Stabilized PKLR reprograms cellular metabolism, antagonizing PARP1-mediated cell death (parthanatos) and promoting tumor cell survival and growth.
Less supported by current evidence, but not ruled out
Dendritic cells, which activate immune T cells, also take in creatine. The creatine helps them produce more energy, which boosts their activation and ability to stimulate T cells that kill cancer cells. This process suppresses tumor growth rather than promoting it.
Dendritic cells upregulate the creatine transporter CrT upon activation by pathogens or inflammatory signals.
Creatine is taken up and converted to phosphocreatine, buffering ATP levels and preventing energy depletion during high activation demands.
Sustained ATP levels support NF-κB signaling, leading to increased expression of costimulatory molecules (CD80, CD86) and proinflammatory cytokines.
These activated dendritic cells prime CD8+ T cells more effectively, enhancing their proliferation and cytokine production.
Increased tumor-specific T cell infiltration and activation suppress tumor growth.
