-
After Digestive Stress → Support Gut Barrier
Diet changes, medication, or illness can stress the gut lining. Serum-derived IgG helps reinforce gut barrier strength.
-
Bloating or Discomfort → Support Digestive Balance
Everyday digestive upset often signals imbalance. Functional proteins help restore equilibrium and ease discomfort.
-
Busy Schedules & Shared Spaces → Support Everyday Resilience
Work, school, or travel test the gut–immune axis. Added vitamin C and selenium help maintain daily resilience.
Your gut lining is where nutrients are absorbed and immune cells communicate — known as the gut–immune axis.
When the lining is strong, it blocks unwanted fragments while allowing nutrients through. When weakened, discomfort, irregularity, or reduced resilience can follow.
That’s why this formula combines serum-derived bovine IgG, vitamin C, and selenium:
- IgG reinforces the gut barrier and supports microbial balance.
- Vitamin C helps maintain antioxidant balance in the gut.
- Selenium contributes to the body’s defense against oxidative stress.
Together, they offer functional protein + antioxidant support for barrier integrity, microbial equilibrium, and daily comfort.
- After digestive stress or diet changes
- During periods of lifestyle/environment strain
