About

A straight-shooter in a hype-drunk category.

We started nadvsnmn because every other NAD⁺ site we could find was either selling something specific, quoting one podcast on repeat, or both. There was no calm, comparative place to answer the actual question — which precursor, which format, which brand, for me.

What we actually do

We compare NAD⁺ precursors (NMN, NR, NAD⁺ itself, NADH), the delivery formats that carry them into your bloodstream (oral capsule, sublingual, injectable, IV drip, nasal spray, transdermal patch), and the brands that sell them — from the ChromaDex-patented big names to the direct-from-China gray market.

Every comparison is built the same way: we read the peer-reviewed literature, we log the study conflicts of interest, we sanity-check bioavailability claims against the actual pharmacokinetic data, and we price everything on a per-milligram basis so you can see which "premium" brands are premium in name only.

The five things we won't do

01

Cite studies without reading them.

Every clinical claim on this site is linked to a real PubMed ID. If we can't verify the source, we don't publish the claim. Full stop.

02

Bury conflicts of interest.

If a study is funded by the company selling the supplement, we tell you. If a "clinical trial" is really a marketing white paper, we say so.

03

Pretend the comparison is closer than it is.

Sometimes the answer is genuinely "it depends." Sometimes it's really not. We won't manufacture nuance to keep every brand happy.

04

Recommend based on affiliate payout.

Some brands pay us more than others when a reader buys. That never — never — determines who ranks first. Payouts and rankings are audited separately.

05

Fake reviews, fake testimonials, fake anything.

There are zero fabricated testimonials on this site. Zero AI-generated "customer stories." Zero stock photos of models pretending to be biohackers.


How we make money

Straightforward: when a reader clicks an affiliate link on this site and buys, the seller pays us a small percentage. Every affiliate link is labeled "Paid link" at the point of click. We're not selling supplements ourselves, we're not running paid webinars, and we don't have a $299 course.

The trade-off is honesty: an affiliate site that rigs its rankings for higher payouts stops being useful to readers, which means fewer clicks, which means less money over the long run. The economics of trustworthy comparison are actually pretty good.

Who's behind this

nadvsnmn is part of a small independent health-content network. We're editorially separate from the brands we cover. We're not owned by a supplement company, we're not a subsidiary of a telehealth platform, and we don't take money for reviews.

Not medical advice. Everything on this site is educational. NAD⁺ precursors are dietary supplements — they're not FDA-approved to diagnose, treat, cure, or prevent any disease. Talk to a licensed physician before starting anything, especially if you're pregnant, nursing, or on medication.
