Clinical studies conducted by Dr.Andrew Keech Ph.D.(an independent world-renowned biochemist and a leading authority on colostrum) shows only Sovereign Laboratories colostrum has adequate amounts of colostrum’s key healing components.

Lactoferrin helps deliver iron to the body where needed. It binds and removes the excess iron that harmful bacteria such as E. Coli, Salmonnella, Staph and Strep need in order to reproduce. The powerful antioxidant properties of lactoferrin help prevent the formation of free radicals in the body that can lead to disease and premature aging. It helps protect other antioxidants such as vitamins C, E and CoQ-10 in the digestive transit so they remain bioactive. It has clinically been proven to destroy HIV, Herpes, Hepatitis and other pathogenic viruses and to help prevent colon cancer in animal studies.

IgG: protects against circulating bacteria and viruses; neutralizes bacterial toxins; triggers the complement system and binds to antigens, enhancing the effectiveness of phagocytic cells.

IgA: 100 times more powerful than IgG and more important for humans. It provides long-term protection against infection in the GI tract. It is the source of most of the truly active anti-bodies for disease prevention and is sometimes called transfer factor for its ability to transfer immunity to the recipient.

PRPs (Proline-Rich Polypeptides) are the only true immune modulators. They help balance the immune function by regulating the thymus gland, which produces T-cells. PRPs also helps balance an overactive immune response which characterizes auto-immune conditions. PRPs do this by inhibiting overproduction of T-cells and lymphocytes, which leads to a reduction in pain and swelling. PRPs have been shown to help reduce Alzheimer’s symptoms and to delay their onset. PRP are cell signaling peptides that are involved in arterial wall and brain cell integrity.

Other US sourced colostrum lacks growth factors due to improper processing. Why is this important: IgF-1 the most prominent factor helps retain and increase lean muscle tissue, burn fat stores for fuel rather than muscle tissue (stop catabolism), reduce insulin needs, balance blood sugar, and increase strength and stamina. Other growth factors heal and protect the delicate intestinal lining from damage, help reduce risk of colon cancer and are involved in angiogenesis (reduction of blood vessel growth to cancer tissue) and apoptosis cell signaling that allows the immune system to clean out cancer cells before they become tumors.

Most importantly, without an adequate protective delivery mechanism, colostrum products are either digested or simply pass through the body intact, providing only minimal benefit. Clinical trials have proven that ONLY Sovereign Laboratories Colostrum-LD® is effective. It helps ensure that the colostrum’s healing components survive the digestive transit and are delivered to where the body needs them.
