NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It carries electrons in the reactions that turn food into cellular energy, and it is used by enzymes involved in DNA repair, including the sirtuins and PARPs.
NAD+ levels fall with age in animal studies and in some human tissues, which is why it is a focus of healthy-ageing research. Most human data come from oral precursors such as NR and NMN, which reliably raise NAD+ in the blood. Evidence for effects on energy, focus or ageing in people is still early and mixed, and published data on injected NAD+ are limited.
Each box holds two pre-filled pens, each containing 500 mg NAD+, so 1,000 mg in total. Every pen is genuine Alluvi Healthcare stock, manufactured in Germany, with its batch number and expiry date printed on the box and a numbered holographic GMP seal across the lid.
Alluvi notes that brief stinging or redness at the injection site is a normal, well-documented response to NAD+ and not a fault in the product.
