Some dietary supplements can do serious harm, especially when taken in high doses. A recent study found cancer associated with high doses of the supplement nicotinamide riboside (NR), which is a form of vitamin B3.
Keep in mind that this study was done in vivo and in vitro (in a lab), and also in mice.. and not humans. But the results are concerning.
Swiss and Univ. of Missouri researchers found that high levels of NT could increase the risk of developing triple-negative breast cancer, and also for it to metastasize to the brain. Yikes.
By the way, while NR can be purchased as a supplement, it is normally not found in ordinary multi-vitamins that many take daily. Low levels of NR are found in fruit, vegetables, meat, and milk - it is necessary for health (it increases levels of cellular energy). It's the large amounts found in supplements that the researchers were concerned with and that can be problematic.
Stay tuned for further research...
While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research from the University of Missouri has found NR could actually increase the risk of serious disease, such as development of breast cancer and brain metastasis. ...continue reading "A Dietary Supplement That Might Increase Cancer Risk"
