DIYNAD+ Injection Pen

  • Feel steadier energy: through the day so you can do more with less drag.
  • Support mental clarity: for deep work and decision‑making.
  • Back‑up cellular function: NAD+ is central to how cells make energy.
  • Keep your routine simple: with pre‑measured, every‑other‑day dosing.
  • Clinic‑style convenience at home:  no waiting rooms, no fuss.

A clean, easy‑to‑use auto‑injector delivering concentrated NAD+. Designed for everyday maintenance, first‑time users, and anyone who wants reliable support without stepping up to high‑strength.

NAD+ is a coenzyme found in every cell, involved in cellular energy production. Levels naturally decline with age. The pen helps you keep your intake consistent - so you can feel more ready for work, training and busy days.

Use every other day as directed. The pen is sized for a 28‑day plan when following the standard schedule. Pair with a subscription so you never run out.

How to start

  • Your DIYNAD+ Pen kit consists of everything you need to self-administer injections. This typically results in high bioavailability, ensuring that a greater amount of NAD+ is directly available to the body’s cells. By bypassing the digestive tract, they avoid the first-pass metabolism by the liver.

  • We suggest a monthly dosage of 750mg, divided and administered every other day. With the supply of pure, active NAD+ and included pen injection equipment, you can easily self-administer the treatment, empowering you to optimise your health and vitality on your own terms.

  • We recommend administering the NAD+ solution on an alternate-day schedule from the outset. Each vial delivers 14 doses, offering approximately four weeks of consistent NAD+ supplementation, without the need for consecutive-day loading.

Benefits

DNA Repair

Scientific:NAD+ acts as a critical substrate for PARP (poly ADP-ribose polymerase) enzymes that detect and repair DNA strand breaks. Maintaining adequate NAD+ levels supports genomic stability, counteracting the cumulative DNA damage associated with aging and environmental stress.


Layman’s:NAD+ helps your cells repair damaged DNA - like a built-in maintenance system that keeps your body’s blueprint strong and youthful.

Energy Metabolism

Scientific:NAD+ is essential in redox reactions that drive cellular respiration, transferring electrons in glycolysis and the mitochondrial electron transport chain. It underpins ATP production, making it fundamental for energy metabolism.


Layman’s:Your cells use NAD+ to turn food into energy. Higher NAD+ levels mean your body can produce energy more efficiently, helping you feel more alert and active.

Sirtuin Activation

Scientific:Sirtuins (SIRT1–7) are NAD+-dependent deacetylases that regulate gene expression, stress resistance, and longevity pathways. NAD+ availability directly controls sirtuin activity, influencing metabolic health and cellular resilience.


Layman’s:NAD+ switches on “longevity enzymes” called sirtuins that help protect your cells, regulate metabolism, and slow down aspects of the aging process.

Cell Signaling

Scientific: NAD+ serves as a signaling molecule influencing calcium signaling, immune response, and intracellular communication. Its metabolites (e.g., cyclic ADP-ribose) play key roles in regulating cellular communication and stress responses.

Layman’s: NAD+ helps your cells talk to each other properly, ensuring they respond to stress and stay in sync for healthy body function.

Mitochondrial Function

Scientific:As a cofactor in mitochondrial oxidative phosphorylation, NAD+ regulates energy transfer and mitochondrial biogenesis. Elevated NAD+ supports efficient ATP production and reduces mitochondrial dysfunction, a hallmark of aging.


Layman’s:NAD+ keeps your cell’s “power plants” (mitochondria) running smoothly, so your body can produce clean, steady energy without fatigue.

Redox Balance

Scientific:NAD+/NADH ratios maintain cellular redox balance, modulating oxidative stress and metabolic pathways. This balance prevents excess free radical formation and supports cellular homeostasis.


Layman’s:NAD+ helps your body control oxidation - the process that causes stress and damage in cells - keeping your system in balance and reducing inflammation.

Healthy Aging

Scientific:By sustaining DNA repair, mitochondrial function, and sirtuin activity, NAD+ counters molecular damage accumulation, improving cellular resilience and promoting healthspan rather than just lifespan.


Layman’s:Rising NAD+ levels help your body age more gracefully - supporting energy, cell health, and vitality as the years go by.

Cognitive Function

Scientific:NAD+ enhances neuronal metabolism, supports mitochondrial energy supply in neurons, and modulates neuroprotective sirtuin pathways (notably SIRT1 and SIRT3), mitigating cognitive decline linked to NAD+ depletion.


Layman’s:NAD+ fuels your brain cells, supporting focus, memory, and mental clarity while protecting against age-related cognitive slowdown.

Immune Support

Scientific:NAD+ regulates immune cell metabolism and inflammatory signaling through CD38 and SIRT1 pathways. Restoring NAD+ improves immune surveillance and reduces chronic inflammation (“inflammaging”).


Layman’s:NAD+ helps your immune system work efficiently - defending against illness while preventing the overactive inflammation linked to aging.

Metabolic Health

Scientific:NAD+ modulates insulin sensitivity, lipid oxidation, and glucose metabolism through sirtuin and AMPK activation. Its decline is associated with obesity, insulin resistance, and metabolic syndrome.


Layman’s:NAD+ supports a healthy metabolism - helping your body process sugar and fat more effectively and maintain balanced energy levels.

Recovery & Performance

Scientific:NAD+ replenishment enhances mitochondrial efficiency, reduces oxidative stress, and improves cellular recovery following exertion or injury by supporting ATP regeneration and inflammation control.


Layman’s:By boosting cellular energy and repair, NAD+ helps your body recover faster from workouts, stress, or fatigue - improving endurance and performance.

  • NAD+ is a crucial co-enzyme present in every cell, influencing energy conversion, DNA repair, and neural communication. It oversees 500+ biological processes, essential for optimal function.

  • With age, NAD+ production diminishes significantly. At 50, it's half the level at 30, and at 70, just 25% remains. The decreasing NAD+ emphasizes its crucial role in aging.

  • Alcohol, pollution, nicotine, and even dehydration result in a decrease in your NAD+ levels, impeding your body's efficient functionality.
