Overview

What is NAD+?

Direct injectable Nicotinamide Adenine Dinucleotide — the universal cellular cofactor for redox reactions, sirtuin activity, PARP DNA repair and mitochondrial respiration. Tissue levels decline ~50% by middle age.

What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide) is a universal cellular cofactor central to redox reactions, mitochondrial respiration, sirtuin activity, and PARP-mediated DNA repair.

Tissue NAD+ levels drop by roughly 50% between ages 20 and 60, a decline that is now considered one of the mechanistic drivers of age-related mitochondrial dysfunction.

Direct injectable NAD+ bypasses the poor bioavailability of oral precursors and elevates tissue NAD+ within minutes.

How does NAD+ work?

NAD+ is required by every mitochondrion for oxidative phosphorylation — the process that produces the majority of cellular ATP.

It is also the required substrate for sirtuin enzymes (SIRT1–7), which regulate longevity-related gene expression, and for PARP1, which mediates DNA damage repair.

Restoring NAD+ pools has therefore become one of the most-studied interventions in longevity research.

Research highlights

• Rapid restoration of cellular NAD+ pools

• Fuels SIRT1/SIRT3 sirtuin activity

• Supports mitochondrial respiration and ATP output

• Studied in addiction recovery, aging and neurodegeneration

Dosing reference (research use)

Common research dosing: 50–300 mg subcutaneously, slowly titrated to tolerance. Some protocols use IV infusion for higher doses.

1 vial = 500 mg. At 100 mg/day, a vial covers ~5 days.

Reported side-effect signals

Facial flushing

Chest pressure at fast infusion rates

Nausea at high doses

FAQ

Common questions

Is NAD+ third-party tested?+

Yes. Every batch of NAD+ ships with an HPLC purity report and identity confirmation from an independent lab. Batch numbers are searchable in our Lab Results portal.

How is it shipped?+

Ambient, insulated mailer, discreet plain packaging. Includes BAC water + 12 syringes. Domestic delivery in 24–48h.

Do you ship internationally?+

Currently US only for research supply. International researcher accounts require verification.

What is the shelf life?+

Lyophilized vials remain stable for 12+ months at −20°C. Once reconstituted, refrigerate at 2–8°C and use within 30 days.
