- The most pure active NAD⁺ on the market
Inside every cell, NAD⁺ powers the processes that keep you alive.
Inside every cell
NAD⁺ is present in all your cells.
It’s the universal cofactor that lets energy and repair systems switch on exactly when needed.
Transfers energy
NAD⁺ shuttles power from food, becoming NADH and driving ATP production in the mitochondria.
That same flow also fuels key enzymes that keep cellular programs calibrated.
Keeps cells strong
Healthy NAD⁺ levels mean steady energy, faster repair, and better redox balance.
Cells stay resilient - supporting clear thinking, endurance, and healthier aging.
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 the closest we’ve gotten to a fountain of youth… without it, you’re dead in 30 seconds.”
- David Sinclair, Harvard Genetics Professor
⚡️ Energy that lasts 12+ hours
🧠 Sharper focus & mental clarity
🔄 Faster recovery & reduced fatigue
Users report more productive mornings, improved mood, and deeper physical and mental stamina - without stimulants or crashes.
Absorption matters.
Not all NAD⁺ is created equal.
Oral capsules break down in your gut. The pen delivers NAD⁺ directly into your bloodstream for fast, clinical-grade results.
Trusted by those who perform at the highest level.
From athletes to entrepreneurs and Hollywood icons, NAD⁺ has become the quiet edge they rely on to stay sharp, recover faster, and push the limits of their performance both mentally and physically.
For so long, NAD⁺ was locked behind £1,000+ IV sessions at private clinics. Now, only DIYNAD+ brings you the purest, cleanest version - made simple and affordable, from just £11.70 per dose.
What makes us different?
More effective. More affordable. Easier to use.
Clinic results.
Without the clinic cost.
As Bryan Johnson explained in his Diary of a CEO interview, NAD⁺ IV drips only provide short-lived benefits - you’d need to go back regularly to sustain results. That means constant clinic visits and thousands spent on treatments, which makes it impractical for most people. The DIYNAD+ Pen was designed to solve this problem: same active compound, but affordable, consistent, and convenient to use at home.
How it works.
Step 1.
Remove the cap from your DIYNAD⁺ pen. Take a fresh NAD⁺ cartridge and insert it into the pen until it sits securely in place.
Step 2.
Twist on a new sterile BD micro-needle. Remove both protective caps to expose the fine tip, ensuring the pen is ready for use.
Step 3.
Turn the dial at the end of the pen to prime it - a small drop will appear at the needle tip. Then, rotate the dial to select your desired dose, shown clearly in the window.
Step 4.
Clean your injection site (abdomen or thigh) using a pre-injection wipe. Press the pen firmly against your skin and push the button to deliver your dose.
