NAD+ explained: why levels drop with age
8 September 2026
NAD+ (nicotinamide adenine dinucleotide) is a molecule found in every cell. It plays a central role in turning food into usable energy.
Why levels change
NAD+ levels naturally decline as we age. That's one reason it has become a focus of healthy-ageing research.
Precursors
Rather than NAD+ itself, many formulas use precursors such as NMN, which the body can use to make its own. NAD+ Longevity is formulated with NMN alongside resveratrol, NAC, lion's mane and cordyceps.
Pairing
Many people pair it with Collagen Pro as part of a skin-and-vitality routine. Results vary, and patches complement a healthy lifestyle.
