WonderCow Colostrum

Colostrum is the nutrient-rich “first milk” produced by mammals in the days immediately after birth. It is naturally concentrated with antibodies, growth factors, lactoferrin, and bioactive peptides that support immune resilience, gut integrity, and overall development. Research shows bovine colostrum supplementation can enhance immune defense, improve intestinal barrier function, and help reduce inflammation. Many people use colostrum to support digestion, immunity, recovery, and vitality. High-quality supplements are typically sourced with a calf-first method, ensuring newborn calves receive their full share before any excess is collected for human use.

Colostrum has been extensively studied for its effects on immunity and gut health. Recent clinical research shows bovine colostrum supplementation reduces the incidence of upper respiratory tract infections and improves gut barrier function (Głabska et al., 2021, Nutrients; Davison et al., 2021, Nutrients). A 2023 meta-analysis found colostrum supplementation in athletes reduced respiratory illness and supported immune function during intense training (Sawada et al., 2023, Frontiers in Nutrition). Colostrum also contains bioactive growth factors that may aid tissue repair, reduce inflammation, and promote healthy aging by supporting the gut-immune axis (Playford & Weiser, 2022, Clinical Nutrition). In fertility and maternal health, colostrum provides early immune protection to newborns, and supplemental colostrum may help balance maternal immunity and microbiome health during the perinatal period (Valladares et al., 2020, Frontiers in Immunology).

Colostrum is typically available in powder or capsule form, often standardized for immunoglobulin (IgG) content. High-quality colostrum should be sourced from grass-fed cows, processed at low heat to preserve bioactivity, and third-party tested for purity. It is best taken on an empty stomach to support gut absorption. Because colostrum is a dairy-derived product, individuals with milk allergies should avoid it.

If you’re taking prescription medications or managing a health condition, check for potential interactions before adding new supplements.
