Bovine colostrum whey comes from cows and is usually produced two to four days after they have given birth. This fluid contains a rich store of antibodies and other substances that help protect calves from infection, enhance their immune function and promote growth. Purported uses for humans include treating diarrhea, promoting overall gastrointestinal health, boosting the immune system and enhancing athletic performance. Like many nutritional supplements, it comes in many forms, but they are all similar in their contents. The Beth Israel Deaconess Medical Center says that evidence supports these uses but that not all studies produced positive results 1.
Beth Israel Deaconess Medical Center says colostrum has not been associated with any significant side effects 1. Potential reactions include nausea and flatulence. Drugs.com notes a lack of scientific literature suggesting that bovine colostrum poses any risk of toxicity 3.
