A few basic supplements are okay to take while cleansing, but you don't need piles of pills. "I'm leery about cleanses that want you to take 20 pills a day," says Marjorie Nolan Cohn, RD, of the Academy of Nutrition and Dietetics. "There's nothing natural about taking that many pills, no matter what they say is in the them."

Instead, Hyman suggests a high-quality multivitamin, fish oil for healthy fats, and additional vitamin D. In short, don't sink big bucks into bottles and bottles of pills that won't really help you.
