Colostrum Colostrum Health Benefits You may have heard that Colostrum – the first form of milk produced by the mammary glands of humans and other mammals immediately after birth – is a unique and powerful superfood. That is quite true and not by any means an exaggeration. Indeed, colostrum is a highly nutrient-rich fluid often referred to as "first milk" or "early milk." It is thick, yellowish, and has a different composition than mature breast milk, which is produced in larger quantities a few days after birthing. https://www.nationalnutrition.ca/food-supplements/colostrum.html #colostrumsupplements
