SBI Protect Powders

SBI Protect Powder by Ortho Molecular Products represents a breakthrough in gut immune support — delivering the only purified, dairy-free immunoglobulin G (IgG) available in dietary supplement form. With 75 grams of pure IgG concentrate per container, this practitioner-trusted formula is designed to strengthen the gut barrier, neutralize harmful microbes and toxins, and reset healthy immune tolerance from the inside out.
The Science Behind IgG and Gut Health
Research has established that the gut barrier plays a central role in overall immune health. When the barrier is compromised, unwanted microbes, toxins, and antigens pass through the gut lumen and trigger immune system activation — a cycle that contributes to chronic inflammation, dysbiosis, and a host of systemic health challenges.
Immunoglobulins — particularly IgG — are the body’s natural solution. They bind to a broad range of microbes and toxins directly within the GI tract, neutralizing them before they trigger an immune response. By eliminating these unwanted triggers early, IgG helps reset healthy immune tolerance and builds a stronger, more resilient barrier against the external environment.
Key Benefits

Concentrated Immunoglobulins for Mucosal Immunity – Pure IgG delivers targeted support to the gut’s mucosal immune system, the body’s first line of defense in the digestive tract.
Microbial Balance Support – By binding and neutralizing a wide range of harmful microbes within the gut lumen, SBI Protect helps maintain a healthy microbial environment.
GI Barrier Health and Integrity – IgG’s binding capabilities have been shown to have a positive effect on gut barrier function, supporting what is commonly referred to as “tight junction” integrity and reducing intestinal permeability.
Normal Inflammatory Balance – By intercepting microbial and toxin triggers before immune activation occurs, this formula helps the body maintain a balanced, healthy inflammatory response.
