NAD+ Cost: Research Vendor Price Comparison

NAD+ is a longevity research compound sold for research use only — it is not an FDA-approved drug, so there is no pharmacy price, no insurance path, and no monthly treatment cost. The only real-world pricing comes from research-chemical suppliers, and it looks different from most peptides: NAD+ is dosed in hundreds of milligrams rather than single-digit milligrams, so the per-mg cost is very small even when a vial isn't.

The table below compares the COA-verified vendors we track, shown both per milligram and per vial so the numbers make sense. Sorted by effective cost per mg after any verified discount, the pattern is consistent — larger buffered multi-gram kits bring the per-mg price down toward the bottom of the range (around $0.07/mg), while a small single vial sits nearer the top.

The biggest swing is quantity. A single 500mg vial can land near the top of the per-mg range, while a large multi-gram kit from the same tier of vendor falls to roughly $0.07/mg. Buffered versus unbuffered form also affects the sticker price, but the headline driver of value is total milligrams per order — always compare on cost per mg and total grams, not on the number on the vial.

The second factor is testing. A price that looks unusually low often reflects unverified purity, and underdosed or contaminated material is expensive at any price. We only list vendors that publish independent, third-party COAs (Certificates of Analysis), so the ranking weighs verification, not just the cheapest sticker. That is also why research-vendor NAD+ and clinic NAD+ IV therapy are not comparable line items — the IV is a compounded, administered service with clinical overhead, and it costs far more than the raw research compound.
