In this final episode of Beneath the Label for the year, host Kathy sits down with Dr. Shelly Hester to unpack the science behind Pharmanex® Colostrum Defense. Together, they explore what colostrum is, why it matters for adults, and how this formula goes beyond a single ingredient to support immune health through clinically studied postbiotics, vitamins, and fiber. From ethical sourcing to daily use and lifestyle context, this conversation breaks down the science in a clear, practical way—just in time for the colder months and holiday season.
