The makers of “drinkable sunscreen” failed to prove their product provides the advertised protection against cancer-causing ultraviolet rays, according to a consumer fraud lawsuit filed this week by the Iowa Attorney General Tom Miller.

The lawsuit against Osmosis LLC and Harmonized Water LLC says the companies “recklessly gave consumers hollow assurances that they were protected from known health hazards.”

But the makers say the product works, and the water contains compounds that deflect UV radiation, forming a barrier on the skin for up to three hours.

The lawsuit says there is no proof those claims are true, pointing to a trial of the water that went unpublished and wasn’t peer reviewed.

In a statement to a BuzzFeed News, the owner of the two companies stood by the product, saying it’s been selling for five years and has had thousands of reorders.

Miller is calling on the court to stop the company from selling the product, and give dissatisfied consumers their money back.
