Episode 7 of Conversations with Dr. Cowan and friends is with the brilliant MIT researcher Dr. Stephanie Seneff today.

Stephanie knows the medical literature on these subjects in a way that few others do. Some of her conclusions will surprise and challenge you. For example, she makes a compelling case that vitamin D supplementation is not a good idea.
