What is NAD+?

Nicotinamide adenine dinucleotide (NAD⁺) is a vital coenzyme present in every living cell. It plays a central role in cellular energy production, DNA repair, and metabolic regulation. NAD⁺ levels decline with age, a change linked to reduced mitochondrial function and increased cellular stress. Buffered NAD⁺ formulations are designed to improve tolerability and stability during supplementation or intravenous administration.

Why is NAD+ Important?

NAD⁺ is essential for converting nutrients into usable energy. It also serves as a substrate for enzymes involved in DNA repair (PARPs) and longevity pathways (sirtuins). Adequate NAD⁺ levels support metabolic efficiency and cellular resilience.

How Does NAD+ Work?

NAD+ is an energy-carrying molecule that is used as a source of energy for biologic processes, especially those involving oxidation/reduction reactions. NAD+ can be thought of as similar to ATP, which is the more widely-known energy-carrying molecule. ATP acts as a more immediate source of energy, like gasoline for a car. NAD+ is more indirect energy, like the electrical system that enables the engine to run efficiently.

What is NAD+ Used for?

In the research realm, NAD+ can potentially help in the following avenues:

  • Age-related metabolic decline
  • Neuroprotection and cognitive health
  • Cellular energy and fatigue
  • DNA repair and stress resistance

Side Effects of NAD+

In research uses, NAD+ is reported to be rarely associated with flushing or nausea if infused too rapidly. Long-term safety data is still evolving.

NAD+ Dosing Protocol (for Research)

NAD+ research protocols call for twice-weekly administration under the skin of a research subject (subcutaneous).

PhaseDose & frequency
Dosing protocol50 mg twice weekly (no up-titration needed)

Common questions about NAD⁺ (buffered)

What is NAD+ (buffered)?

Nicotinamide adenine dinucleotide (NAD⁺) is a vital coenzyme present in every living cell. It plays a central role in cellular energy production, DNA repair, and metabolic regulation. NAD⁺ levels decline with age, a change linked to reduced mitochondrial function and increased cellular stress.

What are the side effects of NAD+ (buffered)?

In research uses, NAD+ is reported to be rarely associated with flushing or nausea if infused too rapidly. Long-term safety data is still evolving.

What is the dosage of NAD+ (buffered)?

One commonly referenced research protocol is: 50 mg twice weekly (no up-titration needed). Shown for education only; a licensed clinician should set any actual dose. See the dosing table.

How do you mix (reconstitute) NAD+ (buffered)?

Wipe the vial tops with alcohol, add bacteriostatic water slowly so it runs down the inside of the glass, then roll the vial gently until the powder dissolves; don’t shake it. See the step-by-step guide with diagrams for the pen and syringe methods.

How much bacteriostatic water do you add to NAD+ (buffered)?

There is no single correct amount. We recommend 2.1 mL: about 0.1 mL is lost during transfer, leaving roughly 2.0 mL of usable solution. You can add more or less (most peptide vials hold up to 3 mL); just enter the amount in the dose calculator. See the step-by-step mixing guide.

Is NAD+ (buffered) FDA-approved?

No. NAD⁺ (buffered) is not FDA-approved in the US (status as of October 2026).
