Creatine is one of the most popular dietary supplements in the world. It helps to improve strength and muscle performance. It may also support brain function. Creatine is considered safe and affordable when used in recommended doses. Recently, scientists have started looking at its benefits beyond fitness.
A UCLA study examined creatine in relation to cancer and immune response. The research was conducted in mouse models and in human cell experiments. It was published in the journal iScience. The findings suggest that creatine may influence how the immune system fights tumours.
Researchers focus on dendritic cells. These cells help coordinate immune attack against cancer. They also studied killer T cells. These cells directly destroy tumour cells. Most current immunotherapy drugs work by targeting T cells, but only a portion of patients respond well. The UCLA team found that creatine may support both dendritic cells and T cells.
A key discovery was that tumour dendritic cells show higher creatine transporter activity. This suggests that immune cells take in more creatine when inside tumours. To test this hypothesis, scientists removed the creatine transporter in dendritic cells.
Creatine was important for dendritic cells. Without it, they become weaker. They were less effective. The cells struggled to activate T cells properly. When creatine levels were increased, immune activity improved. In mice with melanoma, creatine slowed tumour growth. It also increases immune cell activity in tumours.
ATP levels were higher after creatine supplementation. ATP is the main energy source for cells. This helped immune cells stay active in harsh tumour environments. Researchers also tested human dendritic cells in the lab. Creatine improved their ability to activate T cells. This suggests possible benefits for cancer vaccines.
Scientists believe creatine could improve immunotherapy treatments in the future. It may also help prepare immune-cell vaccines better. However, the research is still early. Most of the studies were done in animals. Human clinical trials are still needed. Creatine is generally safe. But cancer patients should consult a doctor before using it.
Future studies will test whether it improves outcomes in patients. Scientists say creatine may support immune metabolism in multiple ways. It may help immune cells keep energy during stress. This finding is important because tumours create a low-energy environment. Immune cells may not work well in these conditions. A better energy supply could help them respond better.
Creatine acts like an energy buffer inside cells. It helps keep ATP levels stable when energy demand increases. This effect could provide insight into the enhancement of immune activity in tumours. The study highlights a possible link between metabolism and immunity.
It suggests that nutrients can influence immune system performance. This opens interest in combining supplements with medical treatments. Still, researchers caution that it is premature to draw conclusions about human treatment.
More controlled clinical studies are required. Until then, creatine should not be considered a cancer therapy. It remains a dietary supplement primarily used for fitness and performance. Its safety record is strong when taken in standard doses. People with medical conditions should seek professional advice before use. Future studies should shed more light on its function in cancer treatment, according to researchers. Currently, we should view the findings as preliminary scientific evidence.
The idea that metabolism can influence immune therapy is gaining attention. Creatine is being studied as one of several metabolic enhancers. It may one day be used with standard immunotherapy drugs. But this possibility is still speculative. Human trials are needed to confirm the benefits. Overall, the UCLA study gives new insight into how immune cells use energy.
It shows how a common supplement may affect cancer biology. More evidence is still needed. Any medical use can’t be confirmed yet. Future studies will see if these findings work in humans too. The next crucial step will be to confirm this.
