Longevity isn’t just about adding years to life—it’s about keeping your body and mind energised as you age. At the centre of this process is NAD+, a molecule that fuels energy production, DNA repair, and cellular resilience. Unfortunately, NAD+ levels naturally decline with age, which can leave you feeling drained and accelerate ageing. That’s where NAD supplements come in, offering a way to restore balance and support healthy ageing.
Evidence-backed forms
Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN) are the most studied. Clinical trials in humans show they raise NAD+ levels in blood and tissues. That’s a real, measurable effect.
This boost supports mitochondrial function, DNA repair, and metabolism—processes tied to ageing and energy.
What they don’t do (yet)
There’s no conclusive human evidence that they extend lifespan. Most longevity data comes from animal studies (mice, worms).
Benefits like sharper cognition, anti-ageing effects, or muscle strength are promising but still preliminary in people.
Who may notice the benefits?
Older adults (since NAD+ declines with age).
People with high energy demands, stress, or poor recovery.
Some users report improved sleep quality, less fatigue, and better endurance.
What matters most
Lifestyle factors (exercise, sleep, fasting) naturally increase NAD+ and may be more impactful than supplements alone.
Supplements seem to work best when paired with these habits.
So, NAD supplements do raise NAD+ levels reliably. Whether that translates into big longevity or performance benefits is still being studied. Think of them as a support tool, not a magic bullet.
