Bloom class action lawsuit overview:

  • Who: Plaintiff Bianca Marinelli filed a class action lawsuit against Bloom Nu LLC.
  • Why: Marinelli claims Bloom Nu falsely advertised its sparkling energy drinks as containing “no artificial colors, flavors, or aspartame.”
  • Where: The class action lawsuit was filed in New York federal court.

A new class action lawsuit accuses Bloom Nu of falsely advertising its sparkling energy drinks as containing “no artificial colors, flavors or aspartame” when they actually contain citric acid, a known artificial ingredient.

Plaintiff Bianca Marinelli says in her class action lawsuit that Bloom sparkling energy drinks are marketed to appeal to health-conscious consumers who want to avoid artificial flavors.

“[Bloom’s] ‘no artificial colors, flavors or aspartame’ representations are featured on the products’ labeling in order to induce health-conscious consumers to purchase drinks that are free from artificial flavors,” the Bloom class action lawsuit argues.

The complaint goes on to allege that Bloom markets its products in a systematically misleading manner by misrepresenting that the products do not contain artificial flavors.

Marinelli’s class action lawsuit asserts claims for violations of New York General Business Law, breach of express warranty and unjust enrichment. She seeks to represent a class of consumers who purchased Bloom sparkling energy drinks within the applicable statute of limitations period.

Class action: Citric acid not natural and may be harmful

According to the Bloom class action lawsuit, citric acid is a common artificial flavor used in food and drink products. Marinelli says that while citric acid can occur naturally in citrus fruits, the citric acid used in Bloom Nu’s sparkling energy drinks is commercially manufactured through a process involving black mold and chemical solvents.

The U.S. Department of Agriculture has reportedly found that it is not commercially feasible to use natural citric acid extracted from fruits, Marinelli says. She argues the U.S. Food and Drug Administration has determined that manufactured citric acid is not natural, but is artificial.

The Bloom class action lawsuit points to a study published in Toxicology Reports Journal that found that manufactured citric acid may trigger inflammatory reactions and allergic responses in some people due to potential impurities from the manufacturing process.

Marinelli claims Bloom Nu’s allegedly deceptive marketing practices have caused consumers to pay a premium for the sparkling energy drinks based on the belief they are free from artificial flavors.

She is seeking compensatory and statutory damages, restitution and an order enjoining Bloom Nu from continuing to market its sparkling energy drinks as free from artificial flavors.

The popular Gatorade sports drink is also facing a class action lawsuit over similar citric acid claims and that it falsely advertises the drink can hydrate better than water.
