Dietary supplement nicotinamide riboside (NR), a form of vitamin B3, is often used to reverse aging, to support brain health and to heal from a number of health issues.

But do the dietary supplements, including NR, have only positive health benefits with no side effects? Actually no, at least according to a recent study on NR.

Researchers found that high levels of NR could not only increase risk of developing triple-negative breast cancer, but also could cause spread of the cancer cells to the brain in the animal model. This is deadly because at this moment there is no viable treatment for brain metastasis.

You can see the results of this study as a careful reminder to think twice before taking any dietary supplements. Do you really need them in your current health condition?
