I-Shield 40pk (1st Gen)
Gut Integrity Support –-Pure Functional Protein (IgG)
When gut and mucosal surfaces are under pressure (from diet, environment or daily stress), the barrier can lose its integrity. I-Shield (1st Gen) brings a concentrated source of serum-derived immunoglobulins (bovine) formulated in New Zealand to help protect gut lining integrity, support mucosal barriers, and help maintain everyday microbial balance and inflammatory balance.

Seasonal changes
When your body feels more sensitive and in need of extra support.
Your gut lining is more than a digestive surface. It’s a key communicator with your immune system.
When balanced, the barrier blocks unwanted fragments while allowing nutrients through. But stress, illness, or antibiotics can weaken it, letting irritants slip through and disrupt comfort.
That’s why I-Shield delivers concentrated IgG. These functional proteins naturally bind to microbial fragments in the gut, helping reduce strain on the lining, maintain integrity, and support daily balance.
