Colostrum is a popular supplement for immune health, but what is colostrum? It is the nutrient‑rich first milk produced by cows after birthing calves. It naturally contains immunoglobulins, proteins, and growth factors that support overall wellness. Immunoglobulins are a specific type of protein that boost the body’s natural immune defenses. They work by identifying foreign substances that the body then knows to eliminate. For a deeper dive, check out our post on The Science Behind Your Immune System. The most common type of immunoglobulin is IgG, a central part of your secondary immune response and key to long-term wellness. Swanson Colostrum Powder features 25% IgG.
Beyond immune health, emerging research indicates that high doses of colostrum may actually support gut integrity and be particularly helpful against exercise-induced inflammation1,2 and GI disruptions.3,4 Beginning an exercise regimen can upset various systems throughout the body, resulting in joint or digestive discomfort; colostrum can help soothe those bumps in the road, making it especially useful for maintaining an active lifestyle.
Colostrum has also been studied for its ability to promote respiratory health by maintaining healthy mucous membranes.5 Its naturally occurring fat content—including omega-3 and -6, conjugated linoleic acid (CLA), and short-chain fatty acids—may protect cellular membrane integrity as well. This is important for proper cellular signaling, immune defense, energy production and more. In addition to protein, nutrient-rich colostrum has been studied for its impact on metabolic health markers such as blood glucose, cholesterol and more.6
