New research suggests creatine supplements may play a role in helping the immune system fight cancer. The study indicates that creatine can give a key energy boost to immune cells involved in directing T cells, which are central to attacking tumor cells.
According to the findings, this added energy may help those immune defenses work more effectively and slow cancer growth. The study also found that when cells were less able to take up creatine, their anti-cancer activity appeared to weaken, pointing to creatine as a potentially important fuel source in this process.
The results add to growing interest in how metabolism and nutrition can affect immune function in cancer. Rather than acting directly on tumors, creatine appears to support the body’s own defenses, especially the immune pathways that help organize T-cell responses.
While the findings are promising, the research is still at an early stage and does not mean creatine is a proven cancer treatment. More work will be needed to understand how it might be used safely and effectively, and whether the same benefits seen in the study apply broadly in patients.
