Aging is associated with a loss of physical and cognitive function, which affects the quality of life for individuals, their relatives, and society. Furthermore, the prevalence of dementia increases among individuals with age-related functional decline.

The results of this study will provide a better understanding of how NR affects the body’s and brain’s functions and metabolism. The project has the potential to offer new insights into whether and how NR can mitigate age-related functional decline. If proven effective, NR could provide a new, non-invasive treatment method to improve the quality of life for a broad population of older adults.

In the study, participants will be randomized to take a high dose of vitamin B3 in the form of NR or a placebo (sugar pill). Vitamin B3/NR is classified as a dietary supplement by the Norwegian Medicines Agency. The substance has no known toxic or harmful effects, and no significant side effects are expected. The medication is taken orally in tablet form.
