Episode Description from the Publisher

In this episode of Aging Less, host Sarah Stancombe sits down with UCSF Clinical Professor and supplement expert Cathi Dennehy to decode the confusing language found on dietary labels. Cathi demystifies complex terms such as "proprietary blends," "standardization," and "tolerable upper limits," providing listeners with the essential tools to look past marketing claims and understand the actual contents of their supplements. The conversation also explores the regulatory landscape of the industry and the potential dangers of medication interactions. Sarah and Cathi discuss how certain supplements can cause adverse effects when combined with prescriptions, emphasizing that "natural" does not always mean safe. This episode serves as a vital guide for navigating the supplement aisle and underscores the importance of consulting a healthcare provider before starting any new regimen.
