Millions of people  the world take dietary supplements  the belief that they will boost their health. New research casts doubt  the benefits  these pills and tablets. A new report  the American organisation Consumer Reports (CR) found serious health risks  supplements that included vitamins, probiotics, and weight loss pills. CR said the biggest problem  supplements is that they are largely unregulated. While medicinal drugs have to be tested  safety and effectiveness, dietary supplements need far less government approval  many countries. This means that consumers are largely  the dark regarding the ingredients of the supplements and how the body will react  them.
Lisa Gill, an editor  CR, said the report showed how dangerous many supplements were. She said they could cause liver failure, kidney failure requiring kidney transplants, seizures, and heart problems. Gill added: "Just because it's not prescription, you say, 'oh, it's safe,' but that's not necessarily true." Gill urges consumers to avoid 15 ingredients commonly found  supplements, including red yeast and caffeine powder. She warned: "There have been deaths associated  each  these." She told people to seek medical help before taking supplements. She said: "Tell your doctor and your pharmacist what you're taking. Treat it like a medication. It's that important. It's really  your health."
