NAD Picks
The NAD Picks standard

Methodology

We rank the companies selling NAD⁺. Those rankings are worth something only if you can see how they are produced, so here is the whole thing: the scoring weights, the rules we hold ourselves to, and the one place commercial relationships are allowed to show up.

How a score is calculated

Every provider score is a weighted average of five marks. There is no field anywhere in this site’s data where a score can be typed in by hand — a rank is an output of the table below, and nothing else.

  • Evidence quality

    30%

    Does the provider's own material describe what NAD⁺ can and cannot do accurately, and does the format they sell have human data behind it?

  • Price transparency

    25%

    Can you find the real, all-in monthly cost — including the consult and any required labs — before creating an account?

  • Value for money

    20%

    What you pay against what you receive, compared with the rest of the category.

  • Ordering experience

    15%

    How straightforward the intake, prescribing and delivery actually are.

  • Clinical support

    10%

    Access to a real clinician after the sale, and how cancellation is handled.

The scoring function does not read commercial status. It is not weighted low; it is not an input at all. Partners are shown first on category pages and labeled “Partner” — that is display order, and it never touches the number. The clearest evidence we can offer that this holds: the format we rate best on evidence is the one we earn nothing from, and we say so on that page.

  1. 01

    Primary sources, never summaries

    Every factual claim is tied to the trial publication, the FDA / DailyMed label, or the peer-reviewed paper of record. We do not cite press releases, secondary blogs, or AI-generated summaries as evidence.

  2. 02

    Citations are live-verified

    Before publication, each reference is checked against the source of record — PubMed, DailyMed, ClinicalTrials.gov — to confirm the authors, year, journal, and the specific figure being cited. Citations are never reconstructed from memory.

  3. 03

    Magnitude over vibes

    We report effect sizes, hazard ratios, confidence intervals, and durations — not adjectives. Where evidence is preclinical or thin, we say so plainly rather than implying more than the data supports.

  4. 04

    Independence, disclosed

    NAD Picks earns revenue through clearly labeled partnerships with vetted telehealth and pharmacy providers. Those relationships are disclosed and never determine a ranking, a verdict, or a safety statement.

  5. 05

    Research, not medical advice

    Our work is educational. It is not a substitute for an individualized consultation with a licensed clinician, and we say so on every page that discusses a medication or intervention.

Frequently asked

What sources does NAD Picks cite?
Every factual claim is tied to a primary source — the trial publication, the FDA or DailyMed label, or the peer-reviewed paper of record. We do not treat press releases, secondary blogs, or AI-generated summaries as evidence.
How are citations verified?
Before publication, each reference is checked against the source of record — PubMed, DailyMed, or ClinicalTrials.gov — to confirm the authors, year, journal, and the specific figure being cited. Citations are never reconstructed from memory.
Do commercial partnerships affect your verdicts?
No. NAD Picks earns revenue through clearly labeled partnerships, but those relationships never determine a ranking, a verdict, or a safety statement. Placement can be commercial; the substance of the evidence review is not.
Is anything on NAD Picks medical advice?
No. Our work is educational research, not a substitute for individualized care from a licensed clinician. We say so on every page that discusses a medication or intervention.
