More Information
Heal The Gut Lining. Feel Like Yourself Again.
(2.5 g ImmunoLin® + 1 g NAG/serving • 3.7 oz • 30-day supply)
Immunoglobulin support to calm and restore gut integrity.
Think of your gut lining as a castle wall: it lets nutrients in and keeps unwanted things out. Probiotics add more guards. IgGI Gut Vitality™ supports the wall itself.
Benefits
Why It Feels Different From Other Gut Products
- No probiotics to keep alive (works alongside Probio Vitality™ or the one you already take)
- No herbs that can upset sensitive stomachs
- No handful of capsules: just one scoop a day
- Tasteless and mixes into water, coffee or a smoothie
Who Notices the Biggest Difference
- “I'm bloated no matter what I eat”
- Anyone with a sensitive gut or food sensitivities
- Anyone who has taken a lot of antibiotics or NSAIDs
- Athletes who train hard and feel it in their gut
Ingredients & Usage
Supplement Facts (per scoop)
- Serum-derived bovine immunoglobulin concentrate (ImmunoLin®): 2.5 g. Immunoglobulins that bind unwanted microbial compounds so your body can clear them.
- N-Acetyl-D-Glucosamine (NAG): 1 g. A building block your body uses for the protective mucus layer of the gut.
Very low in dairy proteins (this is not colostrum); tolerated by most people with milk sensitivity.
Suggested Use
- Mix 1 scoop daily into water, coffee, or smoothie
How it works
Why Did We Create IgGI Gut Vitality™?
Probiotics and fiber are wonderful, but they mostly add more good guys. They don't directly support the lining itself or help clear out what's already irritating it.
That's exactly what this powder is for, with just two ingredients. ImmunoLin® acts like tiny handcuffs, grabbing unwanted bacterial fragments so your body can escort them out. NAG supplies the raw material for the slippery protective mucus layer that keeps the wall strong.
ImmunoLin® has been studied in more than 30 human studies for digestive comfort and gut barrier support.

Quality You Can Trust
Physician Exclusive Quality
Our supplements are available to the public exclusively through our doctors, including here in our online store. No prescription is needed to order.
Superior to Store Bought
Any store carries supplements; far fewer can tell you exactly what’s inside. Potency, purity, and accuracy vary widely from label to label, so it’s hard to know what you’re truly getting or how effective it will be. That’s the standard we hold ourselves to.
Trusted Potency Control
The supplement industry is loosely regulated, meaning labels may not reflect actual dosages. Our physician-guided formulas ensure every ingredient and amount is scientifically validated for optimal health and immune support.
Frequently Asked Questions
What is serum-derived bovine immunoglobulin (SBI)?
SBI is a concentrated source of immunoglobulins (antibody proteins) from bovine serum. In the gut, they bind unwanted microbial compounds, supporting gut barrier integrity and immune balance.
Can I take it with a probiotic?
Yes! They do different jobs. Probio Vitality™ supports your good bacteria, and IgGI Gut Vitality™ supports the lining they live on.
