When digestion turns reactive — bloating, loose stools, or foods you used to tolerate suddenly not sitting right — a compromised gut barrier is often part of the picture. SBI Protect by Ortho Molecular is a concentrated, dairy-free source of serum-derived immunoglobulins (IgG) that bind microbes and toxins in the digestive tract so your body can clear them before they trigger the immune system, helping reinforce the gut lining and calm an overactive immune response.
| Brand | Ortho Molecular Products |
| What it is | Serum-derived bovine immunoglobulin concentrate (IgG) |
| Form | Capsules |
| Free from | Dairy and gluten |
| Best for | Gut-barrier integrity and immune resilience |
| Pairs well with | MegaMucosa, L-Glutamine, a daily probiotic |
SBI Protect is a wellness supplement, not a substitute for medical care. Persistent, severe, or worsening GI symptoms — or blood in the stool, unintended weight loss, or fever — warrant evaluation by your physician.
Immunoglobulins are the antibodies your immune system uses to recognize and bind unwanted material. SBI Protect delivers concentrated immunoglobulin G (IgG) that stays in the gut, where it binds microbes and toxins and helps escort them out before they reach and irritate the gut lining. With fewer triggers reaching the barrier, the immune system stays calmer and the gut lining is better able to maintain its integrity.
Take as directed on the label, or as directed by your healthcare practitioner.
Flourish is a compounding pharmacy with an on-staff pharmacist and nutrition team, so your questions about gut and immune support reach people who do this every day — not a warehouse. Explore Gut Health, Immune System, or pair it with MegaMucosa, L-Glutamine, Restorflora probiotic.
What is SBI Protect?
A concentrated, dairy-free immunoglobulin (IgG) supplement from Ortho Molecular that binds microbes and toxins in the gut to support the gut barrier and immune balance.
What are immunoglobulins, and what do they do?
Immunoglobulins are antibodies. The IgG in SBI Protect binds unwanted microbes and toxins in the digestive tract so the body can clear them before they irritate the gut lining.
Is SBI Protect dairy-free?
Yes. The immunoglobulins are serum-derived, not from dairy, so it avoids the milk proteins found in colostrum- or whey-based products.
How is SBI Protect different from a probiotic?
A probiotic adds beneficial bacteria. SBI Protect does not add bacteria; it binds and helps clear the things that irritate the gut, which is why the two are often used together.
Can I take it with probiotics or L-glutamine?
Yes. They are complementary and commonly combined in gut-support routines; stack or space them as your practitioner advises.
Is it made from beef?
It is a purified bovine serum immunoglobulin concentrate. It contains no dairy and no gluten.
Who should not take it?
Anyone with a known sensitivity to bovine-derived products, and anyone with severe or persistent GI symptoms who has not been evaluated — check with your provider first.
