As we age, our bodies undergo profound changes at the cellular level. One of the most important molecules that declines with age is NAD+ (Nicotinamide Adenine Dinucleotide) a coenzyme essential for energy production, DNA repair, and overall cellular health. This is where NMN (Nicotinamide Mononucleotide) comes in. NMN has gained attention as a powerful supplement for supporting longevity, metabolic health, and gut function. Here’s what the latest science reveals about NMN, how it works, and why it’s becoming a cornerstone in healthy aging research.
What is NMN? (Nicotinamide Mononucleotide)
NMN is a naturally occurring compound found in small amounts in foods like broccoli, cucumbers, and avocado. Inside the body, NMN acts as a direct precursor to NAD+, meaning it helps replenish the NAD+ our cells need to function properly. Without NAD+, our bodies cannot efficiently:
- Convert food into usable energy
- Repair damaged DNA
- Support brain and heart function
- Maintain metabolic balance
Unfortunately, NAD+ levels decline with age, making NMN supplementation an attractive option for those interested in longevity and optimal health.
Why NAD+ Declines with Age
By midlife, NAD+ levels in our cells may drop by nearly 50%. This decline is linked to:
- Fatigue and slower metabolism
- Reduced DNA repair capacity
- Higher risk of cardiovascular decline
- Neurodegenerative conditions
