Do NAD supplements work

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 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.
