Urgent warning about the industrial chemical DNP, or 2,4-Dinitrophenol.

DNP, or 2,4-Dinitrophenol, is an industrial chemical that has become popular amongst some people wanting to lose weight rapidly, including bodybuilders and people with eating disorders. DNP is usually sold online or via social media as tablets or capsules.

Danger to health

DNP is poisonous to humans and can lead to severe health problems including:

  • blindness
  • high body temperature
  • death

Sales of DNP have been increasing in the UK in recent years, and a number of people have become seriously ill since the start of 2015, with DNP contributing to a significant number of deaths and instances of serious harm to health in the UK.

What should you do?

The Scottish Food Crime and Incidents Unit is appealing for anyone in Scotland with information on the sale of DNP to report it to the free and confidential Scottish Food Crime Hotline, which is operated in partnership with Crimestoppers on 0800 028 7926. You can also report any concerns using our online form.
