The formula

What it is

NMN (nicotinamide mononucleotide) is the molecule your cells convert into NAD+, a coenzyme involved in energy production and DNA repair. Each capsule holds 500 mg, a dose studied in published human trials. It's the only active ingredient in the jar, and nothing is hidden in a blend.

Where it fits

For a routine you can account for.

For people looking for a single-ingredient NMN formula with the active amount stated clearly and the evidence presented with its limits.

The mechanism

How it works

NAD+ is involved in cellular processes including turning food into usable energy. NMN sits one enzymatic step before NAD+, which is why researchers study it as a way to raise NAD+ by mouth.

What the research supports

Evidence, graded without shortcuts.

  • 01

    Oral NMN raises blood NAD+ levels in adults.

    Several randomized controlled trials at 250 to 900 mg a day [1][2][3].

    Strong
  • 02

    NAD+ declines with age.

    Well documented in several tissues, still being mapped in others [4].

    Emerging
  • 03

    Effects on energy, sleep and physical performance.

    Smaller, shorter trials with mixed results [2][3].

    Emerging
  • 04

    Long-term healthspan or lifespan in humans.

    No human data yet. We don't claim it.

Daily use

How to take it

  1. 01

    Keep the jar somewhere you'll see it every morning. That matters more than you'd think.

The first twelve weeks

What to expect, week by week

  1. Day 1

    Your first capsule.

    You won't feel anything yet, and that's expected. NMN isn't a stimulant. There's nothing to notice on day one.

  2. Week 3

    The quiet week.

    This is where most routines stall, because nothing tells you to wait. The research window is longer than the first few weeks.

  3. Weeks 8 to 12

    The window the trials measured.

    Published NMN studies measured changes in blood NAD+ over roughly this period. Research on energy, sleep and exercise is still developing.

  4. Week 12

    Your honest review.
