Creatine Energizes Cancer-Fighting Immune Cells: UCLA
SkimNews Take
The same ATP-buffering that powers muscles apparently fuels dendritic cells too — meaning routine creatine use may be quietly shaping immune response in ways no one is currently measuring.

- UCLA researchers found that creatine boosts dendritic cell activity, which activates killer T cells that destroy cancer, according to a study published in iScience.
- Lili Yang, the study's senior author and UCLA microbiology professor, said creatine "energizes the entire infrastructure" supporting T cells, not just the T cells themselves.
- Daily creatine injections significantly slowed tumor growth in mouse melanoma models while increasing both the number and activity of tumor-infiltrating dendritic cells.
- Creatine supplementation raised intracellular ATP levels in dendritic cells, helping maintain inflammatory signaling pathways even as tumors competed for the same nutrients.
- Lab experiments on human cells showed creatine enhanced monocyte-derived dendritic cells used in cancer vaccines, improving their ability to stimulate human T cells against a cancer target.
- Current immunotherapies benefit only 20% to 40% of cancer patients, and the UCLA researchers caution their preclinical findings won't translate without human clinical trials.
Why it matters: For the roughly 60-80% of cancer patients who don't respond to current immunotherapies, this UCLA preclinical work points to creatine as a potential add-on enhancer — but no cancer patient has been tested yet, and the team urges patients to consult their physicians before adding any supplement.
