Try bovine colostrum for gut permeability

What to Do

Take bovine colostrum (3-6g daily) as a supplement to support gut barrier function. Choose a product from grass-fed sources that lists immunoglobulin (IgG) content on the label.

Why It Works

Colostrum contains immunoglobulins, lactoferrin, and growth factors that support epithelial cell repair. A 2017 study in Nutrients found colostrum reduced exercise-induced intestinal permeability by 80% compared to placebo. It also contains proline-rich polypeptides that modulate immune response in the gut.

Tips

• Take on an empty stomach for best absorption
• Most evidence is for exercise-induced gut stress and NSAID damage
• Avoid if you have a dairy allergy (it contains milk proteins)
• Look for third-party tested brands with standardized IgG content
