When it comes to gut and immune health, not all supplements are created equal. Two ingredients that often get compared are bovine colostrum and ImmunoLin®—both rich in immune-supporting compounds, but with important differences.
Let’s break it down.
What Is ImmunoLin®?
ImmunoLin® is a serum-derived bovine immunoglobulin protein isolate (SBI)—which is a fancy way of saying it’s packed with antibodies (called immunoglobulins) that help protect your gut and immune system.
- It contains over 50.5% IgG, the most abundant antibody in the body.
- It’s dairy-free and lactose-free, making it a great option for people with sensitivities.
- It’s manufactured under strict quality controls, ensuring consistent purity and potency
- It’s backed by 45+ human clinical trials, making it one of the most studied ingredients in this space.
And yes, it’s the star ingredient in our Gut Support formula.
What Is Bovine Colostrum?
Colostrum is the first milk produced by cows after giving birth. It’s naturally rich in IgG, growth factors, and nutrients meant to nourish newborn calves. While it’s also used in gut health supplements, it has some limitations:
- Lower IgG content: Typically around 30–40%
- Contains lactose: Not ideal for those with dairy sensitivities
- Inconsistent quality: Varies depending on the cow, timing, and handling
- May contain endotoxins: Which can trigger inflammation and GI symptoms in sensitive individuals
Why ImmunoLin® Comes Out Ahead
| Feature | ImmunoLin® | Colostrum |
| IgG Content | Over 50.5% | ~30–40% |
| Dairy-Free | ✅ Yes | ❌ No |
| Clinical Studies | ✅ 45+ trials | Fewer trials |
| Endotoxin Testing | ✅ Ultra-low | ❌ Often untested |
| Batch Consistency | ✅ High | ❌ Variable |
Bottom Line
If you’re looking for gut and immune support that’s clean, consistent, and clinically backed, ImmunoLin® is the clear winner—especially for individuals with dairy sensitivities or those managing chronic inflammation.
That’s why we chose it as the foundation of our Gut Support supplement.
