NAD+ is a coenzyme every cell uses to convert food into energy, and people inject it to push back against the natural age-related drop in NAD+ levels. Most users report it for energy, mental clarity, and recovery; researchers also study it for DNA-repair and metabolic-aging pathways. Human studies confirm injections raise blood NAD+ levels meaningfully, though long-term outcome data is still developing. This page covers reconstitution math and typical daily-or-cycle logging cadence.

How the NAD+ mg ↔ units converter works

This converter is a two-way bridge between dose mass (mg or mcg) and the unit count you actually draw on an insulin syringe. Once you set the NAD+ concentration of your current vial, you can type any mg value and read the units back, or type any unit count and read the mg back. It is the same math as the dose calculator, but bidirectional, which matters when you are checking a dose someone else recorded in units against a protocol written in mg.

The formula in both directions: mg = mL × concentration mg/mL, and units = mL × 100 on a U-100 syringe. With a 20 mg/mL NAD+ solution, 50 mg comes out to 250 units, and 250 units comes out to 50 mg. The converter handles the unit flip automatically so you never multiply or divide in your head while holding a syringe.

Concentration is the input that changes the answer most. A 100 mg vial diluted with 1 mL is twice as concentrated as the same vial diluted with 2 mL, which means the same dose draws half as many units. That is the single biggest source of converter confusion: a remembered unit count from an old vial does not transfer to a new vial reconstituted with different water volume.

Use the converter whenever a protocol or research note is written in one unit and your syringe is labeled in the other. It is also useful for sanity-checking that a planned titration step lands at a unit count you can read accurately on the syringe — under five units gets hard to read, over fifty starts crowding into the back third of a 1 mL syringe.

Why this matters for NAD+

NAD+ — nicotinamide adenine dinucleotide — is technically a coenzyme rather than a peptide, but it is commonly supplied and tracked in the same lyophilized-vial workflow as the peptides on this site. Vial sizes are typically much larger than peptide vials, often 100 mg or 500 mg.

Cadence varies widely between users. Weekly, twice-weekly, and intensive-loading protocols all appear in personal logs. The flexible cadence makes a structured dose log even more useful for retrospectively understanding what was actually done.

Nicotinamide adenine dinucleotide (NAD+) is, from a chemical standpoint, not a peptide. It contains no amino acids and no peptide bonds. Its molecular structure is that of a dinucleotide, which is composed of two nucleotide units joined together through their phosphate groups. One of these nucleotides contains an adenine base, while the other contains nicotinamide. Despite its non-peptide identity, NAD+ is frequently included on platforms dedicated to peptide tracking because it shares an identical supply and self-administration workflow. It is commonly supplied as a lyophilized powder in vials, requiring reconstitution with a diluent prior to use, making it a logical candidate for inclusion in tracking and calculation tools.

NAD+ mechanism in plain English

NAD+ is a coenzyme involved in cellular energy metabolism and is studied in a wide range of contexts. As with every other entry on this site, mechanistic and clinical specifics are out of scope for a calculator page.

From a biochemical perspective, NAD+ functions as a critical coenzyme in a vast number of cellular processes. Its primary role is as an electron carrier in oxidation-reduction (redox) reactions, which are fundamental to metabolism and cellular energy production. During these reactions, the NAD+ molecule can exist in two forms: its oxidized state (NAD+) and its reduced state (NADH). By cycling between these two forms, it facilitates the transfer of electrons from one molecule to another. Additionally, NAD+ serves as a substrate for several important classes of enzymes, including sirtuins and poly (ADP-ribose) polymerases (PARPs). These enzymes consume NAD+ to carry out their functions, which are subjects of intense study related to cellular maintenance and signaling.

Tracking NAD+ unit counts

NAD+ is unusual in this list because the cadence is so variable. The dose log itself is the source of truth for what protocol was actually followed; without it, retrospective analysis is essentially guesswork.

Documenting NAD+ administration requires careful attention to the route, as a key differentiator in study protocols is intravenous (IV) versus subcutaneous (SubQ) delivery. IV infusions are typically observed in clinical or research settings, involving large quantities such as 250 mg, 500 mg, or even 1000 mg, infused directly into the bloodstream over several hours. Tracking for this route should include the total dose, infusion duration, and any observed parameters. In contrast, subcutaneous self-administration involves logging much smaller doses (e.g., 50 mg) on a more frequent schedule. A comprehensive tracking log allows for clear delineation between these two methods, ensuring that the recorded data accurately reflects the significant difference in dose magnitude and delivery pharmacokinetics.

Common NAD+ conversion mistakes

  • Drifting from a planned cadence and not recording the change in real time.
  • Trying to fit a 50 mg dose into a single insulin-syringe draw without re-running the math.
  • Reusing a unit count from a previous vial without re-checking diluent volume.
  • Letting reconstituted NAD+ warm to room temperature on travel days.
  • Not writing the reconstitution date on the vial.
  • Failing to distinguish between NAD+ and its precursors, such as NMN and NR, when recording data, leading to an inaccurate log of which molecule is being observed.
  • Miscalculating the dose volume and not planning for the need for multiple insulin syringes or a single larger syringe to administer the full calculated amount.
  • Confusing the dosing frequency and amount from a loading phase with that of a long-term maintenance phase when scheduling and documenting protocol adherence.

Frequently asked questions about NAD+ mg ↔ units

Is NAD+ a peptide?
Technically no — it is a coenzyme, not a peptide. It is included on this site because it is tracked using the same lyophilized-vial workflow as the peptides, and the same calculators apply.
How is NAD+ reconstituted?
Add a measured volume of bacteriostatic water through the rubber stopper and swirl gently until the powder fully dissolves. A 100 mg vial with 5 mL of BAC water gives a concentration of 20 mg per mL.
How many units of NAD+ are in 50 mg?
On a 100 mg vial reconstituted with 5 mL of bacteriostatic water (20 mg per mL), 50 mg is exactly 2.5 mL or 250 units. That is too large for a single 1 mL insulin syringe and is typically split or delivered with a larger syringe.
Is NAD+ dosed weekly?
Cadence varies enormously between users — weekly, twice-weekly, and intensive loading protocols all appear in personal logs. Recording the cadence explicitly in each entry is essential.
How long does a 100 mg NAD+ vial last?
At a 50 mg weekly dose, a 100 mg vial provides 2 doses — about 2 weeks of supply. The vial duration calculator runs the math for any combination of vial size, dose, and frequency.
Does NAD+ need to be refrigerated?
Lyophilized powder is typically stored refrigerated, and the reconstituted vial is kept refrigerated and used within several weeks.
What is the difference between NAD+, NMN, and NR?
NAD+ is the final, active coenzyme used by cells. NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are precursor molecules. In the body's natural pathways, NR is converted to NMN, and NMN is then converted to NAD+. Protocols that involve the administration of NAD+ directly are designed to bypass these conversion steps. When you log your activities, it is critical to specify which of these three distinct molecules you are tracking.
Why are the doses for IV infusion and subcutaneous injection so different?
The two routes of administration are studied with different objectives and kinetics. IV infusions deliver a very large dose (e.g., 500 mg) directly into the bloodstream over a period of hours. Subcutaneous injections involve a much smaller dose (e.g., 50 mg) that is absorbed more slowly from the tissue beneath the skin. Due to this order-of-magnitude difference in dosage and delivery method, it is essential that your tracking log clearly records both the dose and the specific route of administration.
Should I use reconstituted lyophilized powder or a pre-mixed solution?
NAD+ can be supplied in two primary forms. The first is as a lyophilized (freeze-dried) powder, which must be reconstituted with a sterile diluent, such as bacteriostatic water, before it can be used; this process should be carefully documented. The second form is a pre-mixed, chemically stabilized solution that does not require reconstitution. Either form can be studied, but your personal log should accurately document the specific product form you are using, as storage and handling may differ.
Why is the injection volume for subcutaneous NAD+ often so large?
The large volume is a direct result of the molecule's properties and the resulting concentration after reconstitution. For example, dissolving a 100 mg vial with 5 mL of diluent creates a 20 mg/mL solution. To administer a 50 mg illustrative dose from such a vial, a volume of 2.5 mL is required. This is significantly larger than the volume for many peptides and exceeds the capacity of a standard 1 mL insulin syringe, necessitating careful planning for dose administration.
