Swanson High Immunoglobulin Colostrum, 120 Capsules (500 mg per Capsule)

Swanson High Immunoglobulin Colostrum is a dietary supplement formulated to support immune, digestive, respiratory, and metabolic health, using bovine colostrum standardized to a 40% immunoglobulin content. Each serving of two capsules provides 1 gram of colostrum, delivering 400 mg of immunoglobulins, primarily IgG, which are glycoproteins studied for their role in immune function by binding to bacteria and supporting natural killer cell activity.

This product sources colostrum from mature USDA dairy cows not treated with antibiotics, with the material shipped frozen and low-heat dried to preserve proteins and nutrients. The manufacturer notes that the colostrum is an early milk rich in antibodies, peptides, fatty acids, vitamins, and minerals. It is available in a 120-capsule bottle, providing 60 servings, with a suggested use of two capsules one to two times daily on an empty stomach. The product is gluten-free and non-GMO, and it contains milk as an allergen.
