Prime Hydration, the sports drink company co-founded by Logan Paul and KSI, has reached a settlement in a lawsuit alleging the presence of per- and polyfluoroalkyl substances (PFAS) in its products. The lawsuit, filed in August 2023, accused the company of containing these toxic substances, which have been linked to various health issues, including cancer.
The legal action was initiated by Elizabeth Castillo, a California resident, who claimed that independent testing revealed harmful levels of PFAS in Prime’s grape-flavored sports drink. Castillo alleged that the undisclosed presence of these chemicals influenced her purchasing decisions and sought damages for herself and other consumers.

In response, Prime Hydration contested the allegations, with Logan Paul publicly stating that the claims were unsubstantiated and based on “zero evidence.” He emphasized that the lawsuit was “frivolous” and “based on nothing.” ([dexerto.com](https://www.dexerto.com/food/olympic-committees-prime-hydration-lawsuit-ends-as-logan-pauls-company-settles-3034203/?utm_source=openai))
Despite the company’s defense, the case progressed through the legal system. In September 2024, a California federal judge dismissed most of the claims but allowed the breach of implied warranty of merchantability claim to proceed. The court found that Castillo had adequately pleaded that the product was “not fit to be consumed” due to the presence of PFAS.

As of January 2026, the parties have reached a confidential settlement agreement, leading to the dismissal of the case. The terms of the settlement have not been disclosed, and both parties have agreed to bear their own legal fees and costs.

This settlement highlights the ongoing scrutiny faced by beverage manufacturers regarding product safety and transparency. The presence of PFAS, often referred to as “forever chemicals” due to their persistence in the environment and human body, has been a growing concern in various industries. Companies are increasingly being held accountable for ensuring their products are free from harmful substances and accurately labeled to inform consumers.
For Prime Hydration, this resolution allows the company to move forward without the overhang of litigation. However, it also serves as a reminder of the importance of rigorous quality control and transparent communication with consumers, especially in the competitive beverage market.
