Fact check: Has Oprah Winfrey ever endorsed any other weight loss supplements?

Checked on August 29, 2025

1. Summary of the results

Based on the comprehensive analyses, Oprah Winfrey has not endorsed any weight loss supplements. The evidence consistently shows that she has actively warned fans against companies using her name to sell weight loss products, including gummies, and explicitly states she does not endorse such products [1].

The analyses reveal that Oprah has been open about using GLP-1 agonist medications (specifically Semaglutide) as part of her weight loss journey [2] [3]. However, these are prescription medications, not supplements. She has discussed these medications in educational contexts, including conversations with medical professionals like Dr. Ania Jastreboff about GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound [4].

The only legitimate business partnership mentioned is her partnership with WW International (formerly Weight Watchers) [2], which is a weight management program rather than a supplement endorsement.

2. Missing context/alternative viewpoints

The original question lacks crucial context about the widespread fraudulent use of Oprah's name and image to sell weight loss products without her consent. Multiple sources confirm that companies have been illegally using her celebrity status to market weight loss gummies and supplements [5] [1] [6].

An important missing perspective is Oprah's proactive stance against these fraudulent endorsements. She has taken steps to publicly distance herself from these products and warn her audience about companies exploiting her reputation [1].

The question also overlooks the distinction between prescription medications and over-the-counter supplements. While Oprah has been transparent about using medically supervised weight loss drugs, this is fundamentally different from endorsing commercial supplements.

Companies selling weight loss supplements benefit significantly from falsely associating their products with Oprah's trusted brand, as her endorsement would likely generate millions in sales due to her massive influence in the health and wellness industry [5].

3. Potential misinformation/bias in the original statement

While the original question appears neutral, it may inadvertently perpetuate the false narrative that Oprah endorses weight loss supplements. The phrasing "any other weight loss supplements" implies she has endorsed some, when the evidence shows she has consistently refused to endorse such products [1].

This type of questioning could reinforce existing misinformation campaigns where fraudulent companies claim celebrity endorsements to boost credibility. The analyses show that there is no credible evidence that Oprah Winfrey has endorsed any specific weight loss gummies or supplements [6].

The question fails to acknowledge the active fraud occurring in the weight loss supplement industry, where Oprah's name and image are being used without permission to sell products she has never endorsed or even used.
