NAD+ AT HOME Pen Refill Kit 1000mg | 2 Cartridges

NAD+ AT HOME Pen Refills provide a replacement supply for adults who already own the compatible refillable injection pen and are following an established, professionally supervised routine. NAD+, or nicotinamide adenine dinucleotide, is a naturally occurring cellular coenzyme involved in redox reactions and normal energy metabolism. This refill-only pack contains two pre-filled glass cartridges, each holding 500 mg of NAD+ in 3 ml of solution, for a total labelled content of 1000 mg. It also includes sterile micro-needles, antibacterial preparation wipes and a sharps-disposal container. The product does not include the reusable auto-injector pen or travel case and should not be used without appropriate instruction, clinical suitability assessment and safe injectable-product handling.

The Science of NAD+ Cellular Metabolism

NAD+ is present in living cells and repeatedly cycles between oxidized NAD+ and reduced NADH forms. This cycle allows electrons to move through metabolic reactions involved in converting carbohydrates, fats and proteins into usable cellular energy. NAD+ also serves as a substrate for several cellular enzymes, although the wellness effects of supplemental or injectable NAD+ remain under investigation.

Cellular Redox Activity: NAD+ accepts electrons during normal metabolic reactions and becomes NADH. NADH can then transfer those electrons within pathways involved in mitochondrial energy production.

Enzyme Co-Substrate Role: NAD+ is used by enzymes involved in cellular signaling, DNA-damage responses and metabolic regulation. Its biological importance does not by itself demonstrate that injectable supplementation produces anti-aging or cognitive benefits.

Evidence-Limited Delivery: Subcutaneous delivery bypasses the digestive tract, but high-quality human evidence regarding long-term benefits, optimal protocols and comparative effectiveness remains limited. Product use should therefore remain professionally guided.

Use and Handling Guide

This refill kit is intended only for people who already own the compatible NAD+ AT HOME refillable pen and have received appropriate instructions. Confirm cartridge compatibility and review the current supplied guide before use. Do not select, increase or change an administration amount without qualified clinical direction. Use a new sterile needle for every application, never share the pen or cartridges and place used needles directly into the supplied sharps container. Keep the cartridges refrigerated, protected from direct light and out of reach of children. Do not use a cartridge if its packaging, seal or appearance raises concerns.

Safety Information

This is an injectable refill product and should not be treated like a routine oral supplement. A qualified healthcare professional should assess suitability before use, especially during pregnancy or breastfeeding, with cancer, immune suppression, bleeding disorders, heart-rhythm conditions, chronic disease, infection or regular medication use. Incorrect injectable technique or contaminated equipment may cause pain, bruising, bleeding, infection or tissue injury. Seek urgent medical assistance for breathing difficulty, facial swelling, severe dizziness, fainting, chest symptoms or signs of a serious allergic reaction. Stop use and obtain advice if persistent headache, nausea, palpitations or an unusual injection-site reaction occurs. Never reuse needles or dispose of them in household waste.
