Restore what time takes.

Introducing Niagen® Plus IV — pharmaceutical-grade NAD⁺ therapy, delivered intravenously by clinicians for direct cellular replenishment. Engineered, not assembled.

01 · The Science

Your cells run on NAD⁺. Aging runs it down.

NAD⁺ (nicotinamide adenine dinucleotide) is the coenzyme that powers cellular energy, DNA repair, and metabolic regulation in every living cell. By age 50, levels can decline by more than 50 percent — and the symptoms are familiar: lower energy, slower recovery, diminished resilience.

Oral precursors raise NAD⁺ steadily over weeks. Intravenous delivery bypasses digestion entirely, depositing NAD⁺ directly into the bloodstream at a bioavailability oral capsules cannot match.

Oral Precursor

Capsule pathway

Absorbed through the gut, processed by the liver, then circulated. Effective and convenient — best as a daily foundation.

Bioavailability~30%

Niagen® Plus IV

Direct infusion

Administered intravenously by a licensed clinician. NAD⁺ enters circulation immediately, with no digestive loss.

Bioavailability100%

02 · The Experience

A single session. Clinician-administered.

Niagen® Plus IV is delivered inside partnered longevity clinics, in private treatment suites designed for stillness. A licensed nurse or physician administers the infusion over sixty to ninety minutes — most members rest, read, or work straight through.

Consult

A board-licensed clinician reviews your health history and confirms candidacy in a private intake.

Infuse

A 500 mL Niagen® Plus IV is administered over 60–90 minutes in a quiet treatment suite.

Recover

Return to your day immediately. No downtime, no recovery window required.

03 · The Evidence

Built on two decades of NAD⁺ research.

Niagen® is the most-studied NAD⁺ precursor on the market, the foundation of more than forty-five peer-reviewed clinical trials and twenty years of biochemistry. Niagen® Plus IV applies that science in pharmaceutical-grade form.
