The aging connection

Let’s connect the dots between NAD+ and aging. As the years pass, our bodies undergo changes, and one of those changes involves a decline in NAD+ levels [1]. This connection between aging and decreasing NAD+ is significant for a few reasons:

  • Energy production: NAD+ is a critical player in the energy production process within our cells. As NAD+ levels drop, our cells may become less efficient at generating energy, potentially leading to feelings of fatigue and sluggishness that often accompany aging.
  • DNA repair: NAD+ is also involved in DNA repair mechanisms. As we age, our DNA may sustain more damage, and diminished NAD+ levels could hinder the body’s ability to repair and maintain our genetic code.
  • Age-related conditions: Reduced NAD+ has been associated with age-related diseases such as cardiovascular issues, neurodegenerative disorders, and metabolic problems. Maintaining optimal NAD+ levels could potentially help mitigate some of these health challenges.

Understanding this aging-NAD+ connection is the first step in assessing whether NAD+ supplementation could be a valuable tool in promoting healthier aging and overall well-being.

By addressing the role of NAD+ in the aging process, we can better appreciate why many are exploring ways to bolster their NAD+ levels.
