Will the FDA start regulating supplements?
If the FDA is now going after health claims (see yesterday’s post), will it also start going after dietary supplements? These, as I explained in my most recent column in the San Francisco Chronicle, get to make all kinds of unsubstantiated claims without the FDA being able to do much about them. More and more evidence is coming in suggesting that supplements can be harmful as well as ineffective. The latest example: antioxidant supplements are said to interfere with the beneficial effects of physical activity. Will such studies encourage the FDA to insist that manufacturers demonstrate safety and efficacy before they put supplements on the market? That would be a refreshing change, no?
