F Factor Founder Resolves Gellis Lawsuit

Tanya Zuckerbrot, MS, RD, founder of F-Factor, has resolved her defamation and cyberstalking lawsuit against fashion influencer Emily Gellis after six years of litigation. The settlement includes a $240,000 payment, made in $500 monthly installments over 40 years, and a public video apology from Gellis. The apology must remain pinned to the top of Gellis’ social media profile for three and a half years. Zuckerbrot is preparing to relaunch F-Factor in 2027.

Settlement Terms

Under the settlement, the payment represents reimbursement for trauma treatment Zuckerbrot underwent as a result of the campaign. Gellis agreed to publish a video apology on her social media account acknowledging that the allegations she promoted were not supported by verified evidence.

The agreement requires the video to remain prominently visible to visitors on Gellis’ profile for three and a half years.

“I spent 25 years building my career and F-Factor, only to watch a smear campaign built on lies destroy my company within months. While I was fighting to save everything I had worked for, I was also enduring relentless cyberstalking and harassment that reached into my home and my family's life. An apology cannot undo that damage or give us back those years, but this settlement represents accountability. Now, I'm focused on rebuilding F-Factor, returning to the work I love and reclaiming the future I worked so hard to create.”

Claims In The Case

The lawsuit arose from Gellis’ social media campaign against Zuckerbrot and F-Factor. The lawsuit alleged that Gellis used her platforms to amplify anonymous allegations, including claims of arsenic contamination, serious health harms and personal misconduct.

According to court records, Gellis posted more than 4,500 Instagram stories about F-Factor in 75 days. The release states that the total number of videos and posts about Zuckerbrot over the following years exceeded 50,000, including accusations of drug use, tax evasion and criminal activity.

As stated in the case, F-Factor products were co-manufactured in a pharmaceutical-grade facility and tested for microbiological safety, heavy metals and label accuracy. Certificates of analysis and a toxicology report supported their safety, according to the release.

F Factor Relaunch Plans

F-Factor offers 20/20 fiber and protein powders and bars, alongside nutrition education focused on fiber. Zuckerbrot plans to relaunch the business in 2027, returning to the nutrition education and fiber-focused approach she has championed for more than two decades.
