Leaky Gut: What It Is, How It Starts, and How Colostrum Can Help

If you've been dealing with bloating, brain fog or ongoing digestive discomfort, you may have heard the term leaky gut. But what does it actually mean, and what can you do about it?

In this post, we’ll walk through the basics of leaky gut, what causes it, and how colostrum may naturally support gut repair and long-term digestive health.

What Is Leaky Gut?

Your intestinal lining works like a security filter. Its job is to let nutrients pass through into your bloodstream while keeping harmful particles like toxins, bacteria and undigested food out.

When this lining becomes overly porous, unwanted substances can sneak through. This is what many refer to as leaky gut, also called increased intestinal permeability. Once these particles enter your bloodstream, they may trigger inflammation, immune reactions and a wide range of symptoms.

Common signs of leaky gut include:

• Bloating or gas after meals

• Food sensitivities that didn’t exist before

• Low energy or brain fog

• Frequent immune system flare-ups

• Skin issues like acne or eczema

While not yet considered a formal diagnosis, many health professionals agree that leaky gut contributes to broader inflammation and discomfort in the body.

What Causes Leaky Gut?

A number of everyday factors can weaken the gut barrier:

• Diets high in processed food or sugar

• Excess alcohol or caffeine

• Long-term stress

• Overuse of antibiotics or NSAIDs

• Chronic inflammation

• Imbalance in gut bacteria

Over time, these disrupt the tight junctions in your gut wall and make it easier for harmful particles to slip through.

How Colostrum Supports Gut Repair

Colostrum is the first form of milk produced by mammals. It is rich in nutrients, growth factors and immune-supporting compounds. When it comes to gut health, colostrum does more than ease symptoms, it helps your body rebuild and strengthen the gut barrier itself.

Here’s how:

Supports Gut Cell Regeneration

Colostrum contains growth factors like IGF-1 and IGF-2, which help repair the cells lining your intestinal wall. This encourages a healthier, more resilient barrier.

Reinforces Tight Junction Integrity

Tight junctions are the protein gates between cells in your gut lining. Colostrum has been shown to support these junctions, helping to reduce permeability and prevent unwanted particles from getting through.

Provides Immune Protection

Colostrum is packed with immunoglobulins, especially IgG and IgA, which help identify and neutralize harmful invaders before they can trigger inflammation in your system.

Calms Inflammation

One of colostrum’s most powerful compounds, lactoferrin, helps regulate your immune response and calm inflammation. This is especially helpful if your gut lining is already irritated or damaged.

Balances Gut Bacteria

Colostrum naturally supports a healthy microbiome, making it easier for your gut to maintain balance and fight off harmful bacteria. A well-balanced microbiome is essential for long-term gut integrity.
