What does colostrum mean?
Colostrum is a clear, yellowish fluid produced by female mammals, including humans, shortly after giving birth. It precedes the production of milk and is rich in immunoglobulins, growth factors, and other nutrients. Colostrum plays a crucial role in the development of the newborn's immune system. In medicine and nutrition, colostrum is used as a dietary supplement due to its potential health benefits. The substance is usually harvested from cows, goats, or sheep and is available in various forms, including powders and liquids. Colostrum has been used for centuries in traditional medicine, and recent studies have confirmed its potential benefits for human health.
