Scientists have named a dietary supplement that can protect against dementia.

The dietary supplement nicotinamide riboside (NR) may protect the brain from neurodegenerative diseases such as Alzheimer's disease. HP stimulates the production of nicotinamide adenine dinucleotide (NAD+). It helps repair cells and damaged DNA and regulates redox processes. NAD+ levels decrease with age and, for example, due to obesity or smoking. The lead author of the study believes that the results indicate that HP slows down neurodegenerative processes. Further research is needed to prove this.
