The Better Business Bureau is warning consumers nationwide about Prozenith, a company marketing weight-loss supplements online and through social media ads that appear to feature Oprah Winfrey endorsements.
Consumers report ordering supplements from the company’s website but instead receiving turmeric in the mail. Many say the celebrity endorsements influenced their purchases, but BBB’s investigation found these claims to be AI-generated fakes, part of a growing trend of deceptive online supplement schemes.
In just the last four months, BBB has received 52 negative reviews, 115 complaints, and 172 scam reports about Prozenith, with an average consumer loss of about $300.
“We’re seeing an increase in online supplement scams that use AI-generated celebrity endorsements to mislead shoppers,” said Dené Joubert, Senior Investigations Manager with BBB Great West + Pacific. “These ads look authentic, but the products often aren’t what consumers ordered—and getting a refund can be nearly impossible. When in doubt, check the company out at BBB.org before buying.”
More reasons for concern
BBB’s investigation found that Prozenith allegedly misrepresents its products with false claims such as “FDA approved,” “GMP certified,” and “100% natural ingredients,” and has displayed BBB’s accreditation seal without authorization.
Also, the business's true location is unknown. Prozenith lists an address in Aurora, CO which belongs to a fulfillment company called ShipOffers, but BBB could not verify any active state registration for Prozenith itself. The company appears linked to multiple limited liability companies in Wyoming and Delaware operated by Lucas Busch, a citizen of Brazil.
BBB contacted the company several times between August 19 and October 20, 2025, regarding consumer allegations and advertising claims. While automated email replies were received, the company has not provided substantiation or refunds, and BBB cannot confirm the legitimacy of Prozenith.
The business has recently rebranded as “Slimjaro,” continuing similar marketing and sales practices under that name.
Tips to protect yourself
BBB urges consumers to:
- Be cautious of celebrity endorsements seen only in social media ads or pop-up videos.
- Watch for red flags such as exaggerated claims, missing contact information, or no business registration.
- When shopping somewhere for the first time, use a credit card or other payment method that offers chargeback protection. This is especially important for online purchases from unfamiliar sellers.
- Verify business legitimacy, reputation, and trustworthiness at BBB.org before purchasing.
