NAD+ Pen Refill Guide: Switching Cartridges Made Easy

The Holte NAD+ Pen™ was built to simplify your wellness routine. But like all precision devices, it requires a refill from time to time. Switching cartridges might sound technical at first, but with the right steps it’s quick, safe, and effortless. This guide will show you how to change your NAD+ cartridge, care for your device, and make your regimen seamless.

Why Cartridge Refills Matter

Consistency is key when it comes to cellular health and energy. Missing a few doses can set back your progress. By knowing exactly how and when to switch cartridges, you’ll keep your Holte Pen ready to go, and avoid the frustration of running out at the wrong moment.

When to Replace Your Cartridge

Each cartridge contains a measured supply of NAD+. Depending on your usage, you’ll need to replace it after a certain number of injections. Signs it’s time to switch include:

• The plunger reaches the end of the cartridge
• You’re unable to prime the pen (and the cartridge is empty)
• You’ve reached the recommended usage limit for that cartridge

For most users, this means a new cartridge every 1–3 weeks. 

Step-by-Step: How to Replace Your Cartridge

Follow these simple steps every time you change a cartridge:

1. Prepare Your Space

Wash your hands thoroughly and make sure your pen, new cartridge, and a clean surface are ready. 

2. Remove the Old Cartridge

1. Unscrew the body of the Holte Pen.
2. Pull out the used cartridge carefully.
3. If any liquid remains, dispose of the cartridge safely according to local guidelines.

3. Insert the New Cartridge

1. Check the new cartridge’s seal and expiration date.
2. Insert it into the pen with the rubber seal facing upward.
3. Screw the pen body back together until secure, but don’t over tighten.

4. Prime the Pen

Turn the dosage dial slightly higher than normal and press the plunger until a small drop of liquid appears at the needle tip. Reset the dial to your recommended dose. This step ensures smooth delivery and removes air bubbles.

5. Ready for Use

Attach a fresh needle and continue with your normal routine. Your Holte Pen is now fully loaded and ready to deliver maximum bioavailability.

Storage and Handling Tips

• Opened cartridges: Keep your active cartridge stored in a refrigerator.
• Spare cartridges: Store in the fridge until use.
• Needles: Always use a new sterile needle for each injection.
• Sharps: Dispose of used needles in a sharps container, never regular bins.

Troubleshooting Cartridge Changes

“My new cartridge won’t prime”

Turn the dosage dial slightly higher and press again until liquid appears. If this doesn’t work, check that the cartridge is inserted correctly.

“I see a small leak”

Ensure the cartridge is fully seated and the pen body is snug but not overtightened.

“The plunger is stiff”

Remove and reinsert the cartridge. Sometimes air bubbles cause resistance.
