Mike Huckabee, former governor of Arkansas, dismissed criticisms over a diabetes cure he had previously endorsed in an infomercial.

Republican presidential candidate Mike Huckabee shot at his critics in his recent guesting at "Face the Nation," saying, "If that's the worst thing somebody can say against me, is I advocated for people who have diabetes to do something to reverse it and stop the incredible pain of that, then I am going to be a heck of a good president."

The informercial shows Huckabee saying, "Let me tell you, diabetes can be reversed. I should know because I did it. Today you can, too."  He then tells viewers to set "Big Pharma" aside and starts recommending a "Diabetes Solution Kit" that contained pills he refers to as "weird spice, kitchen cabinet cure."

The pills were made of cinnamon and chromium picolinate. The American Diabetes Association and the Canadian Diabetes Association do not recommend such treatment because it cannot cure diabetes.

The infomercial raised questions about the presidential candidate earning money for the use of his name in endorsing products he claimed can cure diabetes but are unacceptable to medical experts.

According to Fox News, Face the Nation host Bob Schieffer asked Huckabee, "You had lent your name for money to questionable products... What about that?"

Huckabee explained that the pills were not advertised as medicines but as dietary supplements. "That's a misnomer," he said. He added that aside from the dietary supplements, the kit also contained guides on fighting diabetes through regular exercise and a healthy diet, Business Insider reports.

The 59-year-old candidate is aware that after announcing his candidacy for president on the U.S. 2016 election, he will endure more criticism as the race to the White House intensifies.

"There's going to be a lot of criticism thrown my way," he said, according to CBS News.
