Overview
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It sits at the center of how your body turns food into usable energy, repairs DNA, and keeps hundreds of metabolic reactions running. As we age, natural NAD+ levels fall — and that decline is closely tied to lower energy, slower recovery, and the everyday signs of aging.
Maddox NAD+ is a high-purity, independently tested formulation delivered by injection, so it bypasses the digestive system and reaches your bloodstream directly. People reach for it to support steady energy, sharper focus, and a healthier aging process — without the crash that comes from stimulants.
Recharge your cells, renew your energy.
What people look to NAD+ to support, backed by its central role in cellular metabolism:
All-day energy
Fuels the mitochondrial pathways that produce cellular energy (ATP) — steady output, no stimulant crash.
Cognitive clarity
Supports the brain's high energy demand, which many associate with sharper focus and mental stamina.
Healthy aging
Activates sirtuins and DNA-repair enzymes tied to cellular resilience and the aging process.
Recovery & resilience
Underpins the repair and stress-response machinery your cells rely on after exertion.
How it works
NAD+ is a shuttle for the electrons your cells use to generate energy. Inside the mitochondria it cycles between its charged (NAD+) and discharged (NADH) forms, driving the production of ATP — the fuel that powers everything from muscle contraction to brain activity.
Beyond energy, NAD+ is the required fuel for two families of enzymes: sirtuins, which regulate cellular stress and aging, and PARPs, which repair damaged DNA. When NAD+ runs low, both slow down. Restoring it gives these systems the substrate they need to work at their best. Injection delivers NAD+ directly to the bloodstream, avoiding the breakdown that limits oral forms.
How to use
- 1
Reconstitute
If supplied as a lyophilized powder, add bacteriostatic water per the included instructions and swirl gently until fully dissolved.
- 2
Dose
Dosing should be set with a healthcare provider based on your goals and health history — protocols are individualized and not something to self-direct.
- 3
Administer
Administration should be demonstrated and directed by a healthcare provider familiar with your protocol.
- 4
Store
Keep refrigerated after reconstitution and use within the window on your instructions. Keep out of reach of children.
Independently tested, every batch
Every lot is tested by an independent lab and ships with a certificate of analysis, so what's on the label is what's in the vial.
Safety & important considerations
- Talk with a qualified healthcare provider before starting, especially if you take medication or have a health condition.
- The most common sensations — flushing, mild nausea, or chest tightness — are usually tied to injecting too quickly; slowing down typically resolves them.
- Not a substitute for professional medical care, diagnosis, or treatment.
- Stop and seek care if you experience any reaction that concerns you.

Frequently asked questions
How often do people use NAD+?＋
It varies by goal and by person. Many follow a regular schedule set with a provider, then adjust based on how they feel and respond.
Why injection instead of a pill?＋
Oral NAD+ is largely broken down before it's absorbed. Injection delivers it directly to the bloodstream, which is why many people prefer it.
When might someone notice a difference?＋
Responses differ. Some notice energy or focus changes within the first weeks; consistency tends to matter more than any single dose.
Does the flushing feeling mean something is wrong?＋
Usually not — a warm, flushed feeling is common when NAD+ is given too fast. Slowing the injection almost always eases it.
Is Maddox NAD+ tested?＋
Yes. Every batch is independently tested and ships with a certificate of analysis confirming identity and purity.
Can I use it with other products?＋
Many people stack NAD+ with other compounds, but combinations should be reviewed with a knowledgeable provider first.
