Prime Hydration, the sports and energy drink brand co-founded by Logan Paul and KSI, has faced three significant lawsuits since 2023: a PFAS contamination class action in California, a caffeine mislabeling class action in New York, and a trademark infringement suit from the U.S. Olympic and Paralympic Committee. Two ended in confidential settlements, and the third was dismissed with prejudice. Each Prime drink lawsuit targeted a different product issue, so the outcomes don’t all point the same way.
The PFAS Class Action in California
On August 2, 2023, California resident Elizabeth Castillo filed a proposed class action against Prime Hydration LLC in the Northern District of California.1PFAS Pillsbury Law. Castillo v. Prime Hydration LLC, Complaint The complaint alleged that Prime’s grape-flavored sports drink contained per- and polyfluoroalkyl substances — “forever chemicals” — despite being marketed as a healthy beverage with electrolytes, vitamins, and antioxidants.2Milberg. PFAS Prime Hydration Grape Class Action
Independent testing commissioned by the plaintiff reportedly detected eight PFAS compounds, including PFOA and PFOS, in the grape drink. According to the complaint, the detected PFOS level was roughly three times the EPA’s lifetime health advisory for drinking water, set at 0.02 parts per trillion.1PFAS Pillsbury Law. Castillo v. Prime Hydration LLC, Complaint The suit called the product “adulterated” and “misbranded” under the Federal Food, Drug & Cosmetic Act and California’s Sherman Law, and sought more than $5 million in damages and an injunction against sales of the drink without PFAS disclosure.3ClassAction.org.

Prime moved to dismiss in April 2024, arguing Castillo had not shown any “cognizable injury” or imminent threat of future harm.4USA Today.

Castillo v. Prime Hydration LLC Logan Paul publicly called the claims “absolute bull” in a TikTok video, arguing that the EPA treats PFAS measurements below 1.1 parts per trillion as unreliable, pointing to Prime’s activated-carbon and ion-exchange water filtration, and suggesting that any trace PFAS could come from the plastic bottle rather than the drink.
After a settlement conference on January 9, 2026, the parties told the court they had reached an agreement. Castillo filed a stipulation of dismissal on January 27, 2026, and the court closed the case the next day.6Docket Alarm. Castillo v.

The Caffeine Mislabeling Class Action in New York
On April 8, 2024, Lara Vera, a Poughkeepsie resident, filed a separate class action in the Southern District of New York. She alleged that Prime’s 12-ounce energy drinks contained between 215 and 225 milligrams of caffeine per can despite labels listing 200 milligrams, and said she would not have bought the Blue Raspberry flavor had she known. The suit sought $5 million in damages.8USA Today. Prime Drink Lawsuit Update9Courier-Journal. Logan Paul’s Prime Hydration Based in Louisville Faces Lawsuit
On July 31, 2025, U.S. District Judge Katherine Polk Failla dismissed the consolidated case with prejudice, meaning the plaintiffs cannot refile it. The judge found the allegations “conclusory,” noting that plaintiffs never disclosed how many cans were tested, when or where the samples were purchased, or what testing methodology was used, and had failed to fix those gaps across three amended complaints.10Bloomberg Law. In Re Prime Energy Consumer Litigation, Opinion and Order Even accepting the numbers, Judge Failla ruled that an extra 7 to 11 percent of caffeine in a drink already marketed as containing twice the caffeine of competitors would not be material to a reasonable consumer. She dismissed the related claims for New York consumer fraud, breach of express warranty, unjust enrichment, and fraud.11Top Class Actions.

The Olympic Trademark Suit
In July 2024, days before the Paris Games, the U.S. Olympic and Paralympic Committee sued Prime Hydration in the District of Colorado. The USOPC alleged that Prime used protected marks — “Olympic,” “Olympian,” “Team USA,” and “Going For Gold” — on a special-edition hydration bottle featuring NBA player Kevin Durant. The committee said it sent a cease-and-desist letter on July 10, 2024, that Prime kept marketing the product, and that the conduct was “deliberate” and “in bad faith.” It sought millions of dollars in damages.12BBC.

Regulatory and Public-Health Scrutiny
Alongside the lawsuits, Prime Energy drew regulatory attention over its caffeine content. A 12-ounce can contains 200 milligrams of caffeine, which the file compares to roughly six cans of Coca-Cola or more than two cans of Red Bull.15NBC News. Logan Paul Prime Energy Drink Risks Caffeine Kids
In July 2023, Senate Majority Leader Chuck Schumer asked FDA Commissioner Robert Califf to investigate Prime, arguing the brand’s social-media marketing effectively targets children under 18 and that its energy-drink packaging closely resembles its non-caffeinated hydration line. No public record indicates the FDA opened a formal investigation or took enforcement action. Prime said it had complied with FDA guidelines before launch, that its labels warn the product is not recommended for anyone under 18, and that its caffeine content is comparable to other leading energy drinks.16Reuters.

Canada acted more directly. In July 2023, the Canadian Food Inspection Agency recalled more than two dozen energy drinks, including Prime, for exceeding Canada’s 180-milligram-per-serving caffeine limit, with retailers facing fines or loss of operating licenses if they failed to pull the products.17CBC.
