When ephedra became the first dietary supplement to be banned by the FDA after being linked to 155 deaths, manufacturers scrambled to offer "ephedra-free" alternatives. For example, Xenadrine EFX contains bitter orange (Citrus aurantium); but bitter orange is metabolized into synephrine which is still very similar to ephedra in its pharmacodynamics.

At the press conference January 4th, FTC chairman Deborah Majoras discounted the use of testimonials in advertising by pointing out that the person is paid to do so, and that they often had additional diet and personal trainers to help them. She also listed some "red flag" claims that consumers should be wary of:
