I don't watch television but I've seen supplement ads with Dr. Oz's photo. I just assumed he mentioned a supplement in passing and the supplement company ran with it. I didn't know this was Dr. Oz's bread and butter.
While I don't agree that supplements need to be completely controlled by the FTC/FDA, I do agree that the product advertised should be in the bottle. All the negatives that John Oliver mentioned don't just apply to supplements but to the food industry as whole: deaths, mislabeling, lack of nutrients, harmful ingredients, lobbying Congress. It is wrong to think that supplements are what ill society. The regulated prescription drug industry kills 100,000 people a year in the US. Most are people who take the drug exactly as prescribed.
