Enhance your gut and immune resilience with RetzlerRx® Intest-Immune DF Plus, a doctor-formulated, dairy-free powder designed for comprehensive wellness and longevity. This advanced nutritional blend supports optimal immune defense, balanced digestion, and overall vitality for those seeking proactive, daily support.

At the core of this formula is powdered hyperimmune egg, a unique source of naturally occurring IgY antibodies and immunoregulatory proteins shown in human studies to strengthen immune barriers and modulate inflammatory responses.*
It’s paired with larch arabinogalactan, a clinically studied prebiotic fiber that nourishes beneficial gut bacteria and helps promote healthy microbiome diversity—key to both digestive and immune health.*

Together, these science-backed ingredients create a synergistic approach to gut and immune balance—supporting your body’s natural defenses and promoting resilience from within.*
