805: Diet Pills and Supplements | Skeptical Sunday

Claims vs Reality

The gap between what supplement manufacturers claim and what their products actually deliver is vast. David C. Smalley highlights that most over-the-counter supplements are ineffective and often come with unpleasant side effects, such as greasy bowel movements from fat blockers 1. He points out that green tea is one of the few natural weight loss aids that has some scientific backing, though its effects are modest 2.

   

Dangerous Ingredients

Dietary supplements often contain unlisted and potentially harmful ingredients. David C. Smalley explains that the FDA has recalled numerous supplements due to contamination and unapproved drugs, yet these products frequently return to shelves 3. He warns that many supplements marketed for weight loss or physical enhancement are particularly risky and advises consulting a physician before taking any 4.

   

Regulatory Issues

The regulatory landscape for dietary supplements is fraught with challenges. David C. Smalley notes that many products are labeled as FDA compliant, misleading consumers into thinking they are FDA approved 5. He and Jordan Harbinger discuss how the Dietary Supplement Health and Education Act of 1994 has left consumers responsible for their own safety, making it crucial to scrutinize product labels and claims 6.
