Activists with the Illinois Herbalife Campaign called on state Attorney General Lisa Madigan "to conclude an investigation on [the] nutritional supplement maker" at a Tuesday press conference.

"We need the Attorney General's office to conclude their investigation and determine how to best protect Illinois consumers from further abuses by Herbalife," State Rep Will Guzzardi (D-Chicago) said in a release of thr group. "Multilevel marketing schemes like Herbalife often target people with little business experience because they are the most vulnerable to high-pressure offers of entrepreneurship and financial freedom. The harsh reality is that those who fail at the Herbalife business opportunity are those who can least afford it."

Last year, Madigan launched an investigation into Herbalife, "but dozens of victims from Illinois that have filed complaints with her office claiming financial losses due to Herbalife's deceptive practices are frustrated that they are not receiving the adequate support from Madigan's office," according to a release from the Illinois Herbalife Campaign.

"I came forward to file a complaint because Herbalife needs to be held accountable for their actions in our community. But it has been more than a year since the investigation and we have not received an update on the investigation," said Norma, an alleged Herbalife victim that reportedly filed a complaint with Madigan's office last year.

Madigan's office encourages those affected by Herbalife to file a complaint with them. Meanwhile, the activists also implore "additional victims to come forward by calling the Illinois Herbalife Campaign hotline at (855) 701-5437."
