The clearest Prosvent lawsuit on the public record is Robert Ness v. Prosvent LLC, a 2011 fraud class action that was pushed into arbitration and dismissed within about two months. Beyond that single case, the company’s legal footprint is thin, but customers have filed complaints alleging unauthorized charges tied to trial offers, and the wider prostate supplement industry has drawn repeated false-advertising and celebrity-endorsement suits worth knowing about.
The 2011 Fraud Class Action
Robert Ness filed his complaint in Los Angeles County Superior Court, and Prosvent LLC removed it to the U.S. District Court for the Central District of California in September 2011. The court docketed it under “Other fraud.”1CourtListener. Robert Ness v. Prosvent LLC, 2:11-cv-08098
Prosvent moved to compel arbitration within days, arguing that an arbitration agreement bound the parties and that the class claims had to be dismissed. Ness opposed the motion with declarations and objections. Judge R. Gary Klausner granted the motion on November 29, 2011, sending the dispute to arbitration and dismissing the case.
The underlying fraud allegations were never tested on the merits in open court. Whether the parties resolved anything in arbitration afterward is not reflected in the public docket. The speed of the dismissal is itself the point for anyone researching the case: an arbitration clause inside the purchase terms was enough to end the class action before discovery.
Billing Complaints From Customers
Prosvent LLC is BBB-accredited with an A+ rating and has been accredited since May 2018.2Better Business Bureau. Prosvent LLC BBB Business Profile The customer reviews on that same profile describe a recurring billing pattern.
One reviewer said they ordered a 14-day trial that never arrived and then found an unauthorized $103 charge on their account. Another said they canceled inside 30 days but were still billed twice more for shipments they had not approved, and only spotted the charges on a bank statement. A third mentioned that a family member had misunderstood the terms of a television offer. No formal regulatory action against Prosvent LLC is listed in the BBB profile.
These are customer allegations, not judicial findings, and none of them has produced a public lawsuit against the company. They matter here because they describe the kind of trial-to-continuity billing dispute that most often becomes litigation against supplement sellers.
Lawsuits Against Other Prostate Supplement Brands
Prosvent has not been named in the higher-profile prostate supplement cases, but two are worth flagging because searchers often conflate the brands.
In 2013, plaintiff Floyd Luman sued NAC Marketing Co. and former NFL quarterback Joe Theismann in the Eastern District of California over Super Beta Prostate, calling the product an “elaborate hoax” and accusing the company of using an actor posing as a doctor in commercials.3Courthouse News Service.

In April 2026, the estate of Larry King sued Verified Nutrition, maker of the competing ProstaGenix supplement, alleging the company kept using King in advertisements after his January 23, 2021 death and after a July 2025 settlement in which Verified Nutrition agreed to pay $110,000 and stop using his image, name, or likeness by July 14, 2025.5New York Post.

Neither case involves Prosvent. They are useful only as context for the kinds of claims the industry attracts.
