Which supplement companies have disclosed paid advisory relationships with Dr. Oz, and where are those disclosures published?
Executive summary
Dr. Mehmet Oz has publicly acknowledged paid advisory and promotional ties to at least two supplement-related companies — iHerb and Usana — and those relationships have been documented across government financial-disclosure filings, activist filings and multiple news outlets [1] [2] [3]. The most explicit company-level disclosures appear in Dr. Oz’s financial disclosure filings and in his social-media account biographies, while watchdog letters and news reports have republished and analysed those disclosures for the public record [4] [2] [5].
1. Which supplement companies are named in reporting
Reporting and watchdog letters identify iHerb as Dr. Oz’s primary paid advisory relationship in the supplements space — describing him as a “global advisor and stakeholder” for the online supplement retailer — and earlier reporting and his own filings also record paid agreements with Usana, a supplement manufacturer, from his time as a brand ambassador [6] [2] [1] [3].
2. Where the iHerb relationship is disclosed — government forms and platform bios
The iHerb tie is disclosed in the government financial and ethics reporting that journalists and watchdogs have reviewed: news stories cite Dr. Oz’s financial-disclosure filings showing stock and advisory ties to iHerb and note he identified himself on social platforms as “@iHerb Global Advisor & Stakeholder,” a disclosure activists point out is present in bios but often absent from individual promotional posts [1] [2] [5].
3. Where the Usana relationship is disclosed — prior filings and reporting
Dr. Oz’s paid work for Usana is documented in past financial disclosures and reporting on his business relationships; WHYY and other outlets reported that his disclosure documents list paid agreements and promotional work with Usana, including brand‑ambassador arrangements that predate the more recent iHerb link [3].
4. Watchdog filings and media outlets that republished or flagged the disclosures
Public Citizen formally called attention to Dr. Oz’s iHerb advisory status in a letter to the Federal Trade Commission and published that letter online, arguing his social posts promoting iHerb did not include required per‑post disclosures even though his bio noted the paid relationship [2]. Major media organizations — including the Associated Press, HuffPost, Fortune and others — have summarized the same disclosures found in his ethics filings and social‑media profiles, amplifying the government forms and activist letters into broader coverage [1] [6] [5].
5. How and where the disclosures appear in practice — gaps and context
The published disclosures appear in multiple places: formal financial-disclosure documents filed with ethics offices and reported by outlets (cited in news stories and Senatorial correspondence), and in Dr. Oz’s social-media biographies where he lists his iHerb advisory role; watchdogs contend the latter is insufficient under FTC endorsement rules when individual posts tout products without inline ad disclosures [4] [1] [2]. Reporting also documents that some past promotional segments identified sponsoring companies (e.g., a sponsored Ozempic segment), but the supplement relationships raise distinct questions because they combine equity, advisory titles and promotion on social platforms [6] [3].
6. Limits of the record and where to look next
The public record compiled by reporters and Public Citizen makes the case that iHerb and Usana are the supplement firms most clearly tied to Dr. Oz in paid or advisory capacities and shows where those ties were disclosed — in his financial-disclosure paperwork and in social-profile statements, and recirculated in watchdog letters and mainstream press coverage [1] [2] [3] [5]. This reporting does not exhaustively catalogue every minor commercial tie in his past or list every platform version of a disclosure; the primary on‑record documents are the OGE/financial disclosure filings and the published watchdog letters and news articles that cite them [4] [2] [1].
