NAD+ AT HOME Pen Refill Kit 1000mg

Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme present in every living cell, responsible for driving energy metabolism, DNA repair, and cellular communication. As we age, NAD+ levels naturally decline — resulting in fatigue, slower recovery, inflammation, and visible signs of ageing. Replenishing NAD+ via subcutaneous injection bypasses the digestive tract entirely, achieving near 100% bioavailability and rapid cellular uptake.

Each refill kit contains two 500mg cartridges (3ml each), pre-filled with sterile pharmaceutical-grade NAD+ solution. Together they deliver 1000mg per supply cycle — the same clinical dose as the full kit — in a convenient, ready-to-load format engineered for the NAD+ AT HOME auto-injector pen.

Available in 1, 2 and 3 month supply options with progressive savings on longer commitments.

Note: The auto-injector pen and travel case are not included. This refill kit is for existing pen holders only.

• 20 x Sterile micro-needles
• 20 x Antibacterial wipes
• 1 x Sharps bin (for safe needle disposal)
• 1 x Step-by-step instruction guide
