What are the health benefits of bovine colostrum and is it safe?

Answer:

Colostrum is milk produced immediately after giving birth. Colostrum supplements, which are derived from colostrum from cows (bovine colostrum), contain antibodies and other immune proteins including lactoferrin (an iron-binding protein promoted for supporting the immune system), lysozymes (antibacterial agents) and lactoperoxidase (an antimicrobial), which are considered to provide passive immunity (short-term immunity that occurs when a person is given antibodies from another person or animal). Colostrum also contains nutrients including carbohydrates, fats, vitamins and minerals (Playford, Nutrients 2021).

Bovine colostrum is promoted for boosting immunity, preventing respiratory infections, preventing and treating diarrhea, improving gut health, improving athletic performance, preventing hair loss, treating acne, and improving aging skin. Although evidence of benefit for these conditions is promising, it is limited by the small sizes of the available studies and conflicting results.
