Why Colostrum Works So Well
Colostrum is the nutrient-rich “first milk” produced by mammals after birth. It’s packed with powerful immune messengers like immunoglobulins and lactoferrin that help defend the body, along with growth factors that repair the gut lining. In dogs, colostrum supports the gut-immune axis, which is the key communication pathway between the digestive tract and immune system. When this system is supported, dogs are better equipped to handle food sensitivities, seasonal allergies, and inflammatory flare-ups.
Four Leaf Rover’s colostrum is gently processed at low heat and never defatted or altered so your dog gets the full benefit of its naturally occurring compounds in a clean, bioavailable form.
What’s Inside and Why It Matters
→ Immunoglobulins (IgG, IgA, IgM) – Help neutralize harmful microbes, regulate the immune system, and support gut and skin health
→ Lactoferrin – Binds to iron and helps protect against unwanted bacteria while supporting a balanced inflammatory response
→ Growth Factors (IGF-1, TGF-β) – Encourage tissue regeneration and gut lining repair, especially helpful for dogs with leaky gut or chronic GI issues
→ Proline-Rich Polypeptides (PRPs) – Help calm an overactive immune system without suppressing natural defenses
How to Use
Sprinkle over your dog’s food once or twice daily. It can be used as a long-term supplement for chronic gut or allergy issues, or short-term for added support during illness, antibiotic use, or stressful transitions. Safe for puppies, adults, and seniors.
