Fact check: What is the name of the glp1 supplement endorsed by Oprah in her video?

Checked on August 17, 2025

1. Summary of the results

Based on the analyses provided, Oprah Winfrey has not publicly disclosed the specific name of the GLP-1 supplement she uses. Multiple sources confirm that she uses a weight-loss medication and has discussed GLP-1 agonists, but she deliberately chooses not to name the specific drug [1].

The analyses reveal that while various GLP-1 medications are mentioned in discussions about Oprah's weight loss journey - including Ozempic, Wegovy, Mounjaro, and Zepbound [2], as well as Trulicity [3] - these are referenced as examples of GLP-1 agonists rather than as specific endorsements by Oprah herself.

2. Missing context/alternative viewpoints

The original question assumes that Oprah has endorsed a specific GLP-1 supplement by name in a video, but the evidence suggests this assumption may be incorrect. Oprah has been deliberately private about the specific medication she uses [1], which represents a conscious choice to avoid what could be perceived as product endorsement.

This privacy approach contrasts with the typical celebrity endorsement model, where public figures often promote specific products. Oprah's decision not to name her medication could be viewed as:

  • A responsible approach to avoid influencing medical decisions
  • A way to prevent potential liability issues
  • A strategy to maintain credibility while discussing weight loss

The pharmaceutical industry, particularly companies manufacturing GLP-1 medications like Novo Nordisk (Ozempic, Wegovy) and Eli Lilly (Mounjaro, Zepbound), would significantly benefit from high-profile endorsements from influential figures like Oprah, given her massive audience and trusted status.

3. Potential misinformation/bias in the original statement

The original question contains a false premise - it assumes that Oprah has endorsed a specific GLP-1 supplement by name in a video, when the available evidence indicates she has not done so. This assumption could stem from:

  • Misinterpretation of her discussions about GLP-1 medications in general [2] [3]
  • Confusion between discussing a medication category versus endorsing a specific product
  • Potential misinformation circulating online that falsely attributes specific product endorsements to Oprah

The question's framing as fact ("the glp1 supplement endorsed by Oprah") rather than as an inquiry ("Has Oprah endorsed a specific GLP-1 supplement?") demonstrates confirmation bias and could perpetuate misinformation about celebrity medical endorsements.
