DES MOINES, Iowa (AP) — An Iowa judge has permanently barred a Law Vegas company from marketing to state residents following allegations of false advertising. Polk County District Court Judge Eliza Ovrom issued the injunction Tuesday against Au Naturale Health Solutions. It also requires that the company refund Iowa consumers who request one.

Au Naturale Health Solutions sold health and nutrition products in the state, including marine phytoplankton pills and liquid oxygen drops. The company is accused of making false claims about the health benefits of the phytoplankton pills.

The Iowa Attorney General’s Office says its consumer protection division also recorded phone calls with telemarketers making false claims about its products.
