Colostrum is the most important food an offspring can receive from its mother in mammals. Because of the various health benefits of colostrum, many people use it on a regular basis. Bovine colostrum is the ideal substitute for human colostrum as it is not species specific.

Although there are no obvious side effects of colostrum consumption, some people may experience mild side effects depending on the nature of their body and the quantity of colostrum intake. Usually, when you consume colostrum, a variety of toxins are flushed out from your body. When this is happening, you may experience flu-like symptoms. But this is only temporary and will subside as the toxins are completely flushed out from your body.

Side effects like abdominal discomfort and/or diarrhea may also occur when the colostrum consumption is too high and too fast. In strict medical terms, abdominal discomfort and/or diarrhea is not a side effect but the process where the body gets rid of the toxins accumulated during the illness. In any case, you must consult your doctor before consuming colostrum on a regular basis. If you are allergic to milk and milk products, you may experience headache, muscle aches, or stomach distress.

If you suffer from hyperthyroid disease, you should consult your doctor. Although there is no substantial evidence regarding the effect of colostrum on patients suffering from hyperthyroid disease, in some patients the disease worsened after regular consumption.

Also, if you have an injury or wound, there may be heightened pain in these areas while the wound is healing. Under these circumstances, it's wise to lower consumption of colostrum until the pain subsides.

There are no proven side effects of colostrum. The above-mentioned symptoms are temporary and rare. Still, if you are pregnant, nursing, or on medications, consult your doctor before you consume colostrum.
