A form of vitamin B3, and precursor to NAD+, may play a key role in modifying neurodegenerative diseases and protecting brain health in adults. STORY AT-A-GLANCE The trace nutrient nicotinamide riboside (NR), a precursor of nicotinamide adenine dinucleotide (NAD+) and a form of vitamin B3, may help slow brain aging.
NR may help to boost levels of NAD+, which typically declines in the brain with age, leading to metabolic and cellular dysfunction.
The NAD+ precursor niacinamide is also beneficial, but it’s not widely promoted because it costs much less than other NAD+ precursors, including NR.
Since NAD+ declines with age, boosting it has been described as a fountain of youth for extended lifespan and increased resilience to disease.
Vitamins B6, B9 (folate), and B12 are also important for supporting cognitive function as you age and have been shown to play a major role in the development of dementia. When you eat a varied diet based on whole foods, your body enjoys access to the myriad nutrients contained therein. The trace nutrient nicotinamide riboside (NR), a precursor of nicotinamide adenine dinucleotide (NAD+) and a form of vitamin B3, is among them….
