What NAD+ does inside your cells
NAD+ is a coenzyme present in every cell in your body. It sits at the centre of how cells convert fuel into usable energy, and the repair enzymes that keep DNA intact draw on it every time they work. Understanding what it does is more useful than any promise about how you will feel.
Energy metabolism
NAD+ carries electrons through the reactions that produce ATP, the cell's usable energy currency.
DNA repair
PARP enzymes detect and patch damaged DNA. Each repair consumes NAD+.
Sirtuin activity
Sirtuins, the regulatory proteins involved in cellular stress response, cannot function without NAD+.

Answers & Questions
From basic inquiries to intricate details, we've collated the most common queries from our user base.
The Longevity Pen® is a reusable microdose delivery device designed for at-home use. It delivers precise doses of compounds like NAD+ and spermidine subcutaneously, bypassing the digestive system.
Insert a cartridge, prepare the site with an alcohol wipe, set your dose and press. The pen handles the rest. Each cartridge is pre-filled and engineered specifically for the device, so there is no measuring or mixing.
NAD+ is a key coenzyme that drives cellular energy, supports DNA repair and contributes to healthy aging. As its levels naturally decline with age, targeted replenishment can help maintain long-term vitality and soften the early signs of aging.
Every Starter Kit includes the reusable Longevity Pen®, a portable case with ice pack, 10 needles and 10 alcohol wipes. The NAD+ kit adds one N-Core 500 cartridge (500 mg), the Spermidine kit adds one S-Core 200 cartridge (200 mg), and The Longevity Protocol includes one of each.
The pen is designed for self-administration and comes with clear step-by-step instructions and a short instruction video. All cartridges are manufactured in Europe to GMP-grade standards. If you have an existing medical condition or take medication, speak to a healthcare professional before starting.
Most users notice more energy and clearer focus soon after use, although results always vary from person to person.
How often depends on your personal goals. Microdosing once or twice a week is the most common choice for maintaining focus, energy and general vitality. For individual recommendations, we advise consulting a healthcare professional.
Adults who want to take NAD+ or spermidine without visiting a clinic. It is not suitable if you are pregnant or breastfeeding, and if you have a medical condition or take medication you should speak to a healthcare professional first.
Keep cartridges in the supplied case with the ice pack when you are out. For longer storage keep them cool in the refrigerator. The S-Core 200 is trehalose-stabilised and filled under inert gas; both cartridges are free from preservatives.
Oral supplements pass through the digestive system before anything reaches the bloodstream. Subcutaneous delivery bypasses digestion entirely, which is the main practical difference between the two routes.
Yes. The pen comes with a portable case and ice pack to keep cartridges cool. Check airline and destination rules for carrying needles and medical devices before you fly.
NAD+ is a coenzyme found in every cell in your body. It carries electrons through the reactions that produce ATP, and the PARP enzymes that repair DNA consume it each time they work. Sirtuins, a family of regulatory proteins, also depend on it.
