The Federal Trade Commission is distributing a total of $5.9 million in refunds to more than 316,000 people who bought various products that claimed to help people lose weight and prevent cancer. The FTC said that Central Coast Nutraceuticals, Inc., used misleading claims, deceptive free trial offers, and phony endorsements to market Acai Pure as a weight loss product and Colotox as a cancer prevention supplement, and must refund money to consumers who bought them.
