Don’t Waste Any More Time—Measure Your Longevity With NAD+ Testing

Want to really improve your longevity? Start by checking in on your cells—specifically, the NAD+ levels in your cells.  

Biohacking searches are skyrocketing and more people are experimenting with fasting and immersion therapies to wind back their biological clocks. Though studies support the potentials of intermittent fasting and cold therapy to slow cellular aging and reduce the risk of disease, NAD+ testing as longevity targeting resource has gone largely overlooked—until recently.1,2 

What is NAD+?

Nicotinamide adenine dinucleotide, NAD+, is a coenzyme that influences some of the most vital processes in the body, including metabolizing food into energy and regulating cellular processes like DNA repair and immune system functioning.3,4  It acts as a helper molecule throughout the cellular respiration process, resulting in the production of our cell’s most viable energy currency, Adenosine Triphosphate (ATP).5 

Though NAD+ plays an essential role in the body’s upkeep, NAD+ levels naturally decrease over time—a reduction that is associated with common aging markers and age-related diseases, including metabolic disorders and neurodegenerative conditions.

And although we know that a decline in NAD+ levels does occur with age, until recently it’s been hard to determine the velocity of this decline and how it impacts individuals differently. 

Intracellular NAD+ testing—which is now available at Hudson Health—offers a clear and personalized view of the current state of your cellular health, and subsequently, insights into potential risk levels for future age-related diseases, including:

  • Cardiovascular disease
  • Alzheimer’s
  • Parkinsons
  • Type 2 diabetes  

Arming yourself with a baseline analysis is the crucial first step in your NAD optimization journey. From here, you can work with your longevity specialist to implement the best optimization strategies for your body and lifestyle. 

As more research around intracellular NAD+ optimization emerges, comprehensive baseline analyses are crucial for supporting their efficacy.
