In Episode 47 of the Irsfeld Pharmacy Optimal You Podcast, pharmacist Steve Irsfeld sits down with retired entrepreneur turned health advocate, Joseph Cassarino, to explore the groundbreaking science of Pro Immune. Joseph shares his remarkable journey—from building multi-million-dollar companies to coming out of retirement to champion a natural formula that supports the body’s own glutathione production. Learn how this “nature in a jar” supplement works at the cellular level to optimize health, support detoxification, and address issues from oxidative stress to immune resilience. Plus, Joseph explains why most glutathione supplements fall short, the unique benefits for athletes, veterans, and children, and the passion that fuels his mission.
