Observational analysis of more than 25,000 U.S. adults linked higher dietary creatine intake to a modest (~5 %) drop in overall cancer incidence, particularly among overweight men. Laboratory work at UCLA has shown that creatine acts as an energy “backup battery” for tumor‑infiltrating dendritic cells and cytotoxic T cells, boosting intracellular ATP, improving dendritic‑cell survival, and extending T‑cell activity in nutrient‑poor tumour microenvironments. Pre‑clinical mouse models of melanoma confirmed that dietary creatine slows tumour growth and augments checkpoint‑inhibitor efficacy.

A July 2026 iScience paper from the same UCLA team reiterated these mechanisms, documenting pronounced expression of the creatine transporter in tumour‑associated dendritic cells and demonstrating enhanced T‑cell training and tumour‑killing after creatine supplementation. The authors highlighted the low cost of creatine but stressed that human trials, dosing, and supplement quality must be validated before therapeutic use.

Together, epidemiologic, mechanistic and animal‑model evidence suggest creatine could serve as a metabolic adjuvant to broaden cancer‑immunotherapy responses, though definitive safety and efficacy data in patients remain pending.

## Timeline

### 2026-07-30: Creatine Shows Promise in Cancer Immunotherapy Amid Ongoing Supplement Popularity

### 2026-07-25: UCLA Study Shows Creatine Boosts Immune Cells for Cancer Immunotherapy

UCLA researchers found creatine fuels dendritic and T cells, enhancing anti‑cancer activity in mouse models and suggesting a boost for immunotherapy, which currently benefits only 20‑40% of patients.

### 2026-07-12: Dietary Creatine Linked to Slightly Lower Cancer Risk in US Study

A U.S. study of 25,000 adults links higher dietary creatine intake to a modest 5% lower cancer risk, especially in overweight men, though causality remains unproven.
