Colostrum Supplements: Benefits, Side Effects, and What the Science Says
Have you heard breast milk called “liquid gold”? This usually refers to colostrum or the early stages of breastmilk (produced in the first few weeks of birth), which is rich in nutrients, growth factors, and antibodies. Health-conscious consumers are very interested in colostrum as a supplement for a variety of potential benefits.
How is it taken?
The most common colostrum supplements on the market come from cows (bovine colostrum). These are typically sold in health stores and supplement sections of pharmacies as a powder that is placed in a cold liquid like water, milk, or a smoothie, or as a powder-containing capsule taken by mouth.
What is it used for?
Colostrum is being studied for a variety of proposed health benefits including:
- managing bloating and digestive conditions like inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS);
- reducing post-workout recovery time;
- protecting the stomach lining from chronic use of non-steroidal anti-inflammatory drugs (NSAIDs);
- replacing the gut biome to prevent illnesses that may come from the gut (e.g., bacterial, viral, or parasitic infections);
- preventing seasonal illnesses like colds, influenza, and COVID-19;
- promoting collagen production to assist with hair and nail growth and healthy skin;
- preventing or reducing side effects from chemotherapy such as cold sores and a suppressed immune system.
Studies are ongoing and to date, not enough has been completed to draw specific conclusions on whether colostrum provides benefit.
Is it safe to take colostrum?
Individuals with allergies to cow milk or beef-derived protein (alpha gal syndrome) may have a severe reaction to bovine colostrum and should not take it. Lactose may be present in bovine colostrum and should be considered for individuals with lactose intolerance. Additionally, individuals with strong vegan dietary preferences may also consider avoiding colostrum.
Early studies point to good tolerability of bovine colostrum supplements. Some individuals experience nausea and flatulence (gas) with use, but no serious side effects have been reported.
It is important to remember that since it is still being studied, there may be some risks with taking colostrum that are unknown. Bovine colostrum is sold as a non-FDA-approved dietary supplement. Find more information about buying supplements. Your local pharmacist can also be a good resource for helping you select a safe supplement.
Conclusion
Bovine colostrum has potential therapeutic benefits for which studies are ongoing. Although early studies seem to indicate it is well-tolerated, more data is needed before it can be routinely recommended. If you choose to take colostrum, be sure to ask your pharmacist for help in selecting a safe product.
