Supplements, Lies, and a Lengthy Transcript

On October 21, 1993, there was a hearing before the U.S. Senate Committee for Labor and Human Resources, with the long-winded title: Examining How the Federal Government Should Regulate the Marketing and Use of Dietary Supplements and Related Measures, Including S. 784, To Strengthen Federal Standards with Respect To Dietary Supplements.

Vaginal Seeding. Ew. That’s nuts. Hmmm, interesting.

More Trouble for Antioxidants

Antioxidants are now an iconic example of premature hype making its way into marketing and the public consciousness long before the science is adequately understood. There are multiple lessons to be learned in this story, and a new study just emphasizes those lessons further.
