NAD+ 500 mg nasal spray
Half a gram of the coenzyme in a metered nasal spray, the needle-free answer to NAD+ research’s delivery question, honestly flagged as the contested one.
- ISO-certified laboratory
- COA per batch, ≥99% HPLC
- Not yet available, in development
- Research use only
The contested route, honestly sold
Whether intranasally delivered NAD+ reaches cells in research-meaningful quantity is a live question, one this product page states rather than assumes. The spray exists because part of the field investigates exactly that route; buying it is joining that investigation, not settling it. The route comparison page sets out what mucosal delivery gives up in exchange for the missing needle.
Five hundred milligrams metered across the pump reflects coenzyme-scale consumption, the same economics that size the 300 mg pen. Between the two formats sits the delivery question itself, and our comparison page referees it.
| Compound | NAD+ (dinucleotide) |
| Content | 500 mg, metered spray |
| Class | Coenzyme, not a peptide |
| Purity | ≥ 99% (HPLC) |
| Route status | Mucosal delivery contested |
| Twin format | Peptide pen, 300 mg |
| Category | Research use only |
If route certainty matters more than needle-freedom, the pen version is the safer assumption.

A contested route, sold as one
Why a coenzyme reaches the shelf as a spray, and what the format leaves open.
NAD+ arrives as a spray for a reason unlike the peptides around it. It is a dinucleotide coenzyme, not a chain of residues, the PubChem record for the dinucleotide shows the structure, and small-molecule chemistry makes some mucosal uptake arguable where a large peptide simply fails. The needle-free format follows from that argument, not from proof of it. The half-gram fill answers separate logic: a coenzyme is used at a scale that dwarfs the microgram economy of most sequences here, so the bottle’s figure measures how much a study spends.
The route status is the part this page refuses to soften. Whether enough of an intranasally delivered coenzyme actually arrives at cells to matter is an open question, not an assumption; choosing this format enrols in it rather than stepping around it. The chemistry that allows some mucosal transit stays silent on how much completes the journey, exactly the variable under study. A nad+ nasal spray is therefore best read as an instrument for probing a delivery question, not a verdict already returned on it.
Prime, log, keep it cold
The device habits that keep a half-gram metered fill dosing consistently.
A large fill excuses nothing about handling; it rewards precision. Prime the pump to a complete actuation before anything is recorded, then re-prime whenever the bottle has sat unused, so a fresh device does not open on a run of short sprays. Point the tip at the side wall of the nostril, not inward, actuate on a slow breath, and log the spray count beside the batch number. Across five hundred milligrams, a steady per-actuation volume is what makes one session comparable with the next.
Once opened, the coenzyme keeps to the cold schedule every spray here follows. Store it refrigerated, stand it upright so the dip tube stays primed, and write the first-use date on the bottle rather than trusting memory across a long series; the page on degraded material covers what a lapse actually costs. NAD+ in solution is not a thing to leave warm and half-finished; plan the actuations to fall inside the post-opening window, and let the record, date, count, appearance, rather than optimism call the bottle finished.
