NAD Precursor May Improve Cardiovascular Health

heartNAD, or nicotinamide adenine dinucleotide, is found in all living cells. Its oxidized form, NAD+, rose in popularity as a nutritional supplement following a 2013 Harvard study that suggested it might slow aging in mice. A 2018 article by researcher Christopher R. Martens and colleagues in the journal Nature Communications reports that a precursor vitamin to NAD+ called nicotinamide riboside (NR) can stimulate NAD+ metabolism in healthy middle-aged and older adults compared to placebo, which might improve cardiovascular health. In the crossover study, participants received NR or placebo for six weeks, and then received the other option for a second six-week period. NR was associated with increased NAD+ metabolism.

The researchers suggest that more research is needed to investigate whether chronic NR supplementation might be able to reduce blood pressure and arterial stiffness.
