What Our Customers Are Saying...

This is the best product for GI support and helps in supporting the immune system as well. Tastes great!

This has helped with allergies. It has helped.

This colostrum works great when paired with liposomal vitamin c! It's great as a stand-alone product, but when paired, they are a power twin. My daughter had a UTI &40;urinary tract infection&41;, ...more

Sovereign Laboratories Colostrum

We get colostrum from our mother's breast immediately after birth and for about the first 72 hours of life. It was designed by nature to defend and protect us from infection, eliminate the pain and physical stress of birth and help us grow strong and develop optimally. It delivers critical components to prime the immune system and close the natural holes in the infant's gut (Leaky Gut Syndrome). In adults, bovine colostrum provides immune and growth factors to protect against gut-based infections and to keep the gut lining intact. Colostrum-LD is the only substance clinically proven to heal and prevent Leaky Gut Syndrome, now recognized as the primary cause of allergies and chronic and autoimmune conditions.

Pasture-fed, BST*, BSE** and Antibiotic-free

Sovereign Laboratories obtains its colostrum from pasture-fed Grade A dairy cows that are certified to be healthy, BST*, BSE** and antibiotic-free.

All raw colostrum supplied to Sovereign Laboratories is tested to confirm that it is from the first milking (after the calf obtains its needs) and free of antibiotics, hormones and herbicides.

Flash Pasteurized

Our colostrum is flash pasteurized according to the most demanding of the International Standards - 161°F for 15 seconds - to ensure the colostrum will reach the organs and cells; and remain bioavailable at the cellular level.

* BST (bovine somatotrophin) - a growth hormone used to increase milk production in dairy cattle.

** BSE (bovine spongiform encephalopathy) - a fatal neurodegenerative disease in cattle that can be transmitted to humans; known as "mad cow disease."

1500% Increase in Bio-Availability

Only Sovereign Laboratories exclusive Colostrum-LD (liposomal delivery) increases bio-availability by up to 1500%. Without the liposomal delivery advantage, key components of the colostrum are destroyed by stomach acids before they can be absorbed by the body, thus reducing bio-availability and therefore decreasing effectiveness.

Additionally, clinical studies have shown Sovereign Laboratories colostrum to contain higher levels of key healing components than other USA and New Zealand colostrums.

Proline-Rich Polypeptides

Among colostrum's numerous immune factors, the most important and powerful are the PRPs (Proline-Rich Polypeptides). The PRPs help modulate the immune system to fight infection and quell inflammation. Colostrum-LD has always had the most PRPs of any colostrum on the market, and has recently been improved to contain up to 50% more PRPs than before.

Immunoglobulins & Antibodies

These immune factors are critical to providing immunity against a wide range of pathogens affecting humans. Dairy cows are "walking pharmaceutical factories" because they produce natural antibodies to every bacteria, virus and fungi they encounter. Bovine colostrum contains up to 40% more of these immune factors then human colostrum, making it an ideal supplement to protect us from infection.

Growth Factors (Hormones)

Colostrum-LD contains a multitude of bioidentical growth factors including insulin-like growth factor (IgF-1), growth hormone (GH), and transforming growth factors (TgF) which help the body repair and regenerate muscle, bone skin and organ tissue.

GI, Immune and Athletic Performance

Colostrum-LD is the only colostrum proven in clinical trials for GI, immune and athletic performance. It was developed by Doug and Kaye Wyatt with the Sovereign Health Initiative ( and has more than twenty-four years of research and study behind it.
