    The Dark Side of the Wellness Industry: What Those Ads Aren't Telling You

    Summary: In this episode of The Retreat Radio, PA Heather takes a deep dive into one of the fastest-growing trends in healthcare: direct-to-consumer wellness companies and at-home blood testing.   Using a popular subscription lab service as an example, Heather explains the differences between capillary and venous blood draws, why hormone testing requires more than just a convenient at-home kit, and the limitations of small blood samples, monthly testing, and AI-generated lab interpretations.   The conversation expands into the bigger picture of modern wellness marketing, including celebrity endorsements, influencer culture, startup healthcare companies, and why low headline pricing doesn't always mean better value.
