Canadians should not buy or use health products that contain 2,4-dinitrophenol, more commonly known as DNP, because it is toxic and can cause death. Products containing DNP are primarily marketed towards bodybuilders and are promoted online as a "fat burner" or "shredder" and for weight loss. There are currently no health products containing DNP approved by Health Canada because of serious safety concerns.

In the United Kingdom, five deaths between January 2018 and June 2018 have been linked to the use of DNP. Health Canada has been made aware that some Canadians may have purchased products containing DNP online. No deaths have been reported in Canada to date.
