Celsius class action lawsuit overview:

  • Who: Plaintiff Annabelle Nielsen filed a class action lawsuit against Celsius Holdings Inc. and Celsius Inc.
  • Why: Nielsen claims the companies falsely advertise their energy drinks as promoting health and wellness.
  • Where: The Celsius class action lawsuit was filed in Washington federal court.

A new class action lawsuit alleges Celsius falsely advertises that its energy drinks promote health and wellness.

Plaintiff Annabelle Nielsen claims Celsius has misled consumers by promoting its energy drinks as health and wellness products, when, in reality, the drinks do not actually provide the benefits advertised.

Nielsen says the brand advertises purported benefits of its products, such as “accelerating metabolism” and “burning body fat,” that she claims are not supported by scientific evidence and are misleading to consumers.

“Celsius’s promises on the front of the labels… are misleading and unsupported because, as Celsius knows, drinking the products will not ‘accelerate’ a person’s metabolism nor will they ‘burn’ one’s body fat,” the Celsius class action lawsuit says.

Nielsen wants to represent a Washington state class of consumers who purchased allegedly “healthwashed” Celsius energy products from Oct. 26, 2022, through the time of trial.

Class action lawsuit alleges consumers pay ‘premium’ for Celsius energy drinks

Nielsen argues Celsius’ marketing strategy has ultimately led consumers to pay premium prices for its energy drinks, believing they are purchasing a product that offers health benefits.

“Celsius intends for consumers to rely on such claims when deciding which fitness drink or supplement to purchase and knows that consumers are often willing to pay more for products they believe possess those attributes,” the Celsius class action lawsuit says. 

While Celsius has published studies that appear to support its health claims, the studies were funded by the company itself, a fact that is not disclosed to consumers, according to the Celsius class action lawsuit.

Nielsen claims Celsius committed fraudulent concealment and violated the Washington Consumer Protection Act. She demands a jury trial and requests declaratory and injunctive relief and an award of punitive damages for herself and all class members.

In a previous case involving Celsius, a New York federal judge granted final approval in April 2023 to a $7.8 million settlement resolving claims that the company deceived consumers through its “no preservatives” marketing.
