Dosage Guidelines

Getting Started

If you’re new to NAD+ microdosing, we recommend beginning with a 50 mg dose for three consecutive days. This initial loading phase helps elevate your NAD+ levels and creates a strong cellular foundation.


Maintenance Phase
After the first three days, transition to a maintenance rhythm of 50 mg every second or third day, depending on your personal needs, energy levels, and recovery goals.


One Cartridge = 500 mg
Each cartridge contains 500 mg of NAD+, providing up to 10 standard doses. Always monitor your usage and replace the cartridge when empty.

Tip: Listen to your body and adjust your rhythm if needed. Some users prefer slightly more frequent dosing during periods of high stress, travel, or recovery.

FAQ

Questions about the kit.

  • How long does one cartridge last?

    One N-Core 500 holds ten 50 mg doses: about 20 to 30 days at one dose every second or third day.

  • Do I need a prescription?

    Talk to your doctor before you start. Your doctor decides whether it suits you and sets the dose.

  • How do I store the cartridges?

    Store cartridges in a cool, dark place, ideally in the fridge, and never freeze them. Take a cartridge out about 15 minutes before use so it reaches room temperature.

  • Can I add the other cartridge later?

    Yes. The pen works with both N-Core 500 and S-Core 200, so you can order the other cartridge as a refill at any time.

  • What is in the box?

    The Longevity Pen, one N-Core 500 cartridge (500 mg), the travel case with two cooler packs, needles and alcohol wipes.
