1. Gastrointestinal problems such as: diarrhea, abdominal pain, bloating and nausea.
These symptoms may result from an allergy to cow's milk protein or lactose intolerance.

2. Allergic reactions such as skin rashes, itching, swelling or shortness of breath.

3. Risk of infection (if not properly manufactured). If colostrum comes from unreliable sources or is inadequately processed, there is a risk of contamination with bacteria or other pathogens.

4. Metabolic disorders, e.g. changes in blood sugar levels (which is important for diabetics), changes in body weight, especially with long-term use.

If you are considering using Colostrum, it is best to consult with your doctor, especially if you have any underlying medical conditions or are taking other medications.
