What is it?

Some studies suggest that bovine colostrum in various forms can help treat diarrhea or infections.

Bovine colostrum is the milk produced by cows for the first several days following birthing. It is rich in antibodies, growth factors, and cytokines, and protects the newborn calf from infections. It has also been used as a dietary supplement in the last decade.

Several clinical trials suggest that various bovine colostrum preparations may be helpful to treat or prevent diarrhea, but additional studies are needed. Similarly, more studies are needed on the conditions under which it may confer immune function benefits.

Bovine colostrum contains trace amounts of estrogen, so patients with hormone-sensitive cancers should discuss this product with their doctors before consumption. In addition, individuals allergic to dairy products should avoid this product.
