NAD+ (nicotinamide adenine dinucleotide) is a vital, naturally occurring molecule that has an essential role in many biological functions within the human body. Having adequate levels of NAD+ is critical for supporting healthy aging and avoiding age‒related illnesses. However, as people grow older, their natural ability to produce enough of this critical molecule diminishes significantly. This decline has been linked not only to general signs of aging but also to specific conditions like cardiovascular disease or neurodegenerative disorders such as Parkinson’s disease and even Alzheimer’s disease.
Other factors, like chronic inflammation, oxidative stress, and exposure to environmental toxins, can further accelerate the depletion of NAD+ levels. One promising approach for increasing the supply of vital NAD+ molecules within our bodies is through oral supplementation with nicotinamide riboside (NR).
