Has Dr. Mehmet Oz ever endorsed Iron Boost publicly or in paid promotions?

1. What the reporting actually documents: product endorsements and disclosure complaints

Multiple outlets documented that Oz posted frequent endorsements of supplement products online and that a watchdog (Public Citizen) and news organizations found he regularly touted products—particularly from the retailer iHerb—without prominent disclosure of his paid advisory role or financial ties ^{[1] [2] [3]}. Fortune and Bloomberg reported the same Public Citizen letter and examples of posts praising herbal supplements, and a local paper summarized the watchdog’s conclusion that his posts “threaten to run afoul of U.S. marketing rules” by lacking clear ad disclosures ^{[2] [3] [1]}.

2. What the sources say about paid promotions and advisory relationships

The reporting indicates Oz had an advisory or stakeholder relationship with some companies and that he promoted their products on platforms like X (formerly Twitter) and Instagram without making those financial ties prominent in each post, which watchdogs argued violated Federal Trade Commission guidance on endorsements ^{[2] [3] [1]}. Bloomberg and Fortune specifically cite Public Citizen’s letter as the basis for that allegation ^{[3] [2]}.

3. What the sources do not say: the name “Iron Boost” is absent

None of the provided sources mention a product called “Iron Boost.” The articles and watchdog letter referenced name iHerb and “herbal products,” and they cite examples like green coffee bean extract and raspberry ketone, but they do not mention “Iron Boost” or document Oz endorsing that specific product (available sources do not mention “Iron Boost”) ^{[1] [2] [3]}.

4. How to read the evidence: documented pattern vs. a specific claim

The sources establish a documented pattern: Oz publicly endorsed supplements and listed products on social media while sometimes failing to disclose financial ties ^{[2] [3] [1]}. That pattern supports reasonable suspicion that he has engaged in paid or paid-adjacent promotions. However, because the reporting does not cite the product name you asked about, it cannot confirm or deny Oz ever endorsed “Iron Boost” specifically (available sources do not mention “Iron Boost”) ^{[1] [2] [3]}.

5. Competing perspectives and limitations in the record

Watchdog groups and outlets (Public Citizen, Fortune, Bloomberg, The Spokesman-Review) assert nondisclosure and point to specific posts; the sources frame those findings as potentially inconsistent with FTC rules ^{[2] [3] [1]}. The articles do not include a public response from Oz in these excerpts disputing the watchdog’s claims; they instead summarize the watchdog’s letter and social-post examples ^{[2] [3] [1]}. The available reporting may omit any subsequent clarifications, corrections, or paid-disclosure labels Oz may have added later; those are not found in the currently supplied sources (available sources do not mention later clarifications).

6. What you can do next to get a definitive answer

To establish whether Oz specifically endorsed “Iron Boost” and whether that endorsement was paid, check primary sources not included here: his social media archives (X, Instagram), the company’s marketing materials, FTC filing/complaint records, or Public Citizen’s full letter. The supplied reporting supports a broader truth—Oz has publicly promoted supplements and sometimes failed to disclose ties ^{[2] [3] [1]}—but does not confirm the specific product name you asked about (available sources do not mention “Iron Boost”).
