Many people today take dietary supplements to improve their health. One popular supplement is nicotinamide riboside, often called NR.
It is a form of vitamin B3 and is widely promoted for its possible benefits for the heart, brain, and metabolism. Some people also believe it can boost energy levels and support healthy aging.
Because of these claims, NR has become a common choice for people looking to improve their overall well-being.
However, new research from the University of Missouri suggests that this supplement may not be as harmless as many people think. The study raises concerns that high levels of NR could increase the risk of certain types of cancer, especially an aggressive form known as triple-negative breast cancer.
To understand why this might happen, it is helpful to know how NR works in the body. NR helps increase a molecule called NAD, which plays an important role in producing energy inside cells. This is one reason why people believe NR can improve energy and health. But this same process may also create a problem.
Cancer cells need a lot of energy to grow and spread. If a substance increases the energy supply in cells, it may also help cancer cells survive and multiply. This is what researchers wanted to explore in their study.
The scientists examined how NR affects different types of cells, including cancer cells, immune cells, and healthy cells. They found that higher levels of NR may give cancer cells extra energy, allowing them to grow more quickly. Even more concerning, the study suggests that NR may help cancer spread to other parts of the body, including the brain.
When cancer spreads to the brain, it becomes much harder to treat. There are currently very limited treatment options for cancer that has reached this stage, and survival rates are often lower. This makes the findings especially important for both doctors and patients to consider.
The study focused in particular on triple-negative breast cancer, which is known to be one of the most difficult types of breast cancer to treat. This form of cancer does not respond to some of the common treatments used for other types, which makes new risk factors even more concerning.
It is important to note that this research does not mean that NR will cause cancer in everyone who takes it. The study mainly suggests that high levels of NR could increase risk under certain conditions.
However, it does highlight the need for caution, especially for people who may already have a higher risk of cancer or who are dealing with existing health problems.
This research also reminds us that supplements are not always as simple or as safe as they may seem. Many supplements are available without a prescription and are often marketed as natural or beneficial. However, their effects on the body can be complex, and not all risks are fully understood.
The findings from this study may help guide future research and treatment strategies. Scientists hope to learn how to block the harmful effects linked to NR, which could improve cancer treatments. For example, if researchers understand how cancer cells use extra energy, they may be able to design therapies that limit this process and slow down tumor growth.
The study also supports the growing idea of personalized medicine. This approach focuses on tailoring treatment to each individual based on their unique condition.
Different types of cancer behave in different ways, and their response to treatments can vary. By understanding these differences, doctors may be able to create more effective and safer treatment plans.
The research was led by Elena Goun and published in the journal Biosensors and Bioelectronics. While more studies are needed to confirm these findings, the results are an important step in understanding how supplements like NR may affect the body.
For now, this study serves as a reminder that even widely used supplements should be approached with care. It is always a good idea to speak with a healthcare professional before starting any new supplement, especially for people with existing health concerns.
