NAD+

As we age, our bodies experience a significant decline in Nicotinamide Adenine Dinucleotide (NAD+), a critical coenzyme that plays a vital role in cellular health and function.

 

This guide explores how NAD+ levels decrease by approximately 50% by age 40 and the far-reaching implications this decline has on overall health, energy levels, cognitive function, and the aging process.

​

NAD+ testing represents a valuable clinical tool for patients over 40, providing crucial insights into cellular health and guiding personalized interventions. Research has established that intracellular NAD+ levels of 40 µM or higher are associated with optimal cellular function across multiple biological systems. As NAD+ naturally declines with age, testing becomes increasingly important for identifying deficiencies that may contribute to age-related health concerns.

​

For healthcare practitioners, NAD+ testing offers a quantifiable biomarker that can inform targeted therapeutic

approaches. When testing reveals suboptimal levels, clinicians can recommend appropriate NAD+ replenishment strategies, including intravenous therapy, oral supplementation, or lifestyle modifications that naturally boost NAD+ production. This precision approach allows for individualized treatment plans rather than one-size-fits-all recommendations
