Dinks & Drives is built on one molecule and one honest premise: NAD+ (nicotinamide adenine dinucleotide) is central to how your cells produce energy, and its levels decline measurably with age. By around 50, NAD+ in many human tissues has dropped to roughly half of youthful values. That decline maps cleanly onto the demographic that fills the pickleball courts.
The NAD+ salvage pathway
Most of your NAD+ is regenerated through a recycling route called the salvage pathway. The enzyme NAMPT converts nicotinamide into NMN; NMNAT enzymes then convert NMN into NAD+. NMN sits one enzymatic step from NAD+ — which is why supplementing it is mechanistically interesting. Supplemental NMN enters the line after the age-slowed NAMPT bottleneck.
Sirtuins & mitochondrial function
NAD+ is the required fuel for the sirtuins — SIRT1 in the nucleus, SIRT3 in the mitochondria. SIRT1 activates PGC-1α, the master regulator of mitochondrial biogenesis; SIRT3 tunes the efficiency of energy production. A depleted NAD+ pool quietly throttles these renewal signals. Meanwhile the enzyme CD38, which rises with age and inflammation, consumes more and more NAD+ — production falls as consumption climbs.
What the human evidence shows — and doesn’t
The mechanism is well established. Early human trials are encouraging: oral NMN can raise circulating NAD+, with reported signals around walking endurance, aerobic capacity, and muscle insulin sensitivity in older adults. But those studies are small, relatively short, and not always consistent. The dramatic lifespan extension seen in some rodent work does not reliably translate to humans. The honest framing: NMN and NAD+ precursors may support cellular energy metabolism. The longevity claims you see online run well ahead of the proof.
Our manufacturing standard
Every batch is manufactured in a GMP-certified facility and independently third-party assayed for purity, potency, and identity. We publish certificates of analysis to the batch number. In a flooded NMN market where label and contents often diverge, this is the part that isn’t optional.
