Why this guide exists
Searching for NAD+ can quickly become a tangle of product promises, unfamiliar terms, and prices that are difficult to compare. The NAD+ Neighborhood organizes the questions in plain language: what is being offered, what it costs, what the evidence supports, and what you should verify.
We write for readers who appreciate readable type, useful context, and time to think. You can begin with a provider review, a practical guide, or a city page. Each route leads to related reading and primary sources.
What our reviews represent
These are editorial reviews of public information. We have not purchased every product, audited the dispensing pharmacies, or independently measured patient outcomes. There are no invented patient testimonials, clinician endorsements, or customer ratings on this site.
Articles are published by The NAD+ Neighborhood editorial desk. The current articles have not been independently medically reviewed. They are educational information and cannot diagnose a condition or determine whether a prescription is appropriate.
How the site is funded
This is a commercial review site. CoreAge Rx is the featured partner and is deliberately placed first in our comparison articles. We may receive compensation when a reader follows a CoreAge Rx link. That order is promotional, not a finding of superior safety or effectiveness.
We disclose the relationship on the page and in the featured banner. Our reviews still identify uncertainty, pricing discrepancies, membership charges, and other material details found in the sources.
What the geographic directory covers
The directory uses the US Census Bureau’s 2025 Gazetteer, covering 32,058 incorporated places and Census-designated places in the 50 states and the District of Columbia. It does not include every neighborhood or unincorporated settlement.
Location pages combine a shared decision guide with place-specific geography and nearby links. They are not individually verified clinic directories. Distances are calculated between geographic reference points, not clinic addresses, and do not represent driving distances.
