Reset Your Immune System with IgX

Autoimmunity is on the rise globally. It can prevent you from thriving and take hold of your life with brain fog, aches, and mood imbalance. 

One of the main causes is weak gut barrier function caused by poor diet lifestyle, genetics, and environmental factors.  Poor gut function means there’s an altered gut microbiota, decreased nutrient absorption, and an abundance of unwanted organisms. Antigens like bacteria, toxins, and undigested food particles trickle down the gut barrier and trigger the immune system.  

A combination of immune activation and decreased barrier function leads to immune intolerance and GI challenges. When left unchecked, this can lead to major immune system challenges like autoimmunity. 

All Functional Health provides a powerful solution for this immune system challenge. Immunoglobulin X.  Ig X is a purified, dairy-free source of immunoglobulins,  that helps restore gut barrier function. This nutrient binds microbes and toxins in the GI tract and eliminates them, prior to immune system activation.

Along with lifestyle improvements, Ig X ensures microbial balance, healthy barrier function, and immune tolerance to keep you thriving in your day-to-day life. Reset your gut immune function with Ig X.
