What Is Bovine Colostrum and How Does It Support Immune Health?

Bovine colostrum is the nutrient-rich first milk produced by cows within hours of giving birth. Packed with antibodies, growth factors, and immune-supporting proteins, it has been studied for its potential to support the body’s natural defences. Source Naturals Colostrum is true bovine colostrum—not cheese whey—collected within the first 12 hours to preserve its bioactive compounds. Each batch is standardised to ensure that immunoglobulin proteins (IgG, IgA, IgM) make up 30% of the finished product, providing a consistent, high-quality supplement.*

Immunoglobulins are key players in immune function. They help neutralise pathogens and support the immune system’s ability to respond quickly. By delivering a concentrated dose of these proteins, this colostrum supplement may help maintain a healthy immune response, especially during times of stress or seasonal challenges.*

How to Use Colostrum for Best Absorption

For optimal results, take ½ to 1 level measuring teaspoon (approx. 2–3 g) daily on an empty stomach. Mix the powder into water, juice, or your favourite beverage. Because colostrum is rich in proteins, taking it without food may improve absorption. Start with a smaller amount and adjust as needed. Store in a cool, dry place to maintain freshness.
