Colostrum – Is It Worth The Hype

What is Colostrum?

Colostrum is a nutrient-rich fluid produced by mammals, including humans, in the first few days after giving birth. It serves as the initial source of nutrition for newborns, providing essential antibodies, growth factors, vitamins, and minerals to support their immune system and overall health. Colostrum supplements, which are derived from colostrum from cow, contain antibodies and other immune proteins including lactoferrin (an iron-bringing protein that support the immune system), antibacterial and antimicrobial compounds, and nutrients like carbohydrates, fats, and vitamins and minerals.

Potential Benefits of Colostrum:

  1. Immune Support: Colostrum contains high levels of immunoglobulins, antibodies that help protect against infections and boost the immune system. Research suggests that colostrum supplementation may help reduce the risk of respiratory infections, gastrointestinal infections, and other common illnesses.
  2. Gut Health: Colostrum contains bioactive components such as lactoferrin and growth factors that support gut health. These compounds help maintain the integrity of the intestinal lining, support the growth of beneficial bacteria, and may aid in the management of conditions like leaky gut syndrome and irritable bowel syndrome (IBS).
  3. Muscle Growth and Repair: Colostrum is rich in growth factors such as insulin-like growth factor 1 (IGF-1) and transforming growth factor beta (TGF-β), which play key roles in muscle growth, repair, and regeneration. Athletes and fitness enthusiasts may benefit from colostrum supplementation to support muscle recovery and performance.

Evidence-Based Insights:

While colostrum offers promising benefits, it’s essential to examine the evidence behind these claims:

  1. Immune Support: Several studies have shown that colostrum supplementation can help reduce the incidence and severity of respiratory and gastrointestinal infections, particularly in infants and young children. However, more research is needed to determine its effectiveness in adults and specific populations.
  2. Gut Health: Some research suggests that colostrum supplementation may help improve symptoms of gastrointestinal disorders like IBS and leaky gut syndrome, specifically related to damage of the gut lining due to intense exerciseNSAID use, and in critically ill patients. Studies have demonstrated its ability to reduce intestinal permeability, decrease inflammation, and support the growth of beneficial gut bacteria.
  3. Muscle Growth and Repair: Some studies have shown that colostrum supplementation can enhance muscle strength, increase lean muscle mass, and accelerate recovery after intense exercise. However, results have been mixed, and more high-quality studies are needed to confirm these findings.
  4. Skin Health: Bovine colostrum has been promoted for improving aging skin or reducing wrinkles but there doesn’t appear to be any clinical studies of this in people.

While the evidence supporting the benefits of colostrum is promising, it’s important to acknowledge the limitations of research in this field. Many studies are small-scale or conducted on animal models, and more robust clinical trials are needed to validate these findings and determine optimal dosages and applications.

What are the cons to supplementation? 

Bovine colostrum supplements are expensive, ranging from $50 to $100 per 16 ounces. And while the benefits are promising, there are often a lot of other low cost or free changes that clients can make to their lives with greater long term success.

As with all dietary supplements, colostrum supplements are not regulated by the FDA so bioactive compounds found in them can differ considerably. This is based on many factors including the age of the cow, feeding intensity, and exact time after birth, and specific processing methods. In fact, research has shown that the immunoglobulin content of different batches of colostrum ranged significantly even within farms.

There are also ethical concerns with taking colostrum away from baby cows, even when companies claim they are ensuring adequate nursing time.

Who should not take it?

While colostrum appears safe for most people, anecdotal reports of diarrhea, skin rashes, and abdominal discomfort have been reported.

It also contains small amount of estrogens, which may be important to know for women with estrogen-sensitive conditions.

If you are allergic to dairy, you should avoid colostrum.


In conclusion, colostrum shows promise as a natural source of immune-boosting antibodies, gut-supporting compounds, and muscle-building factors. While research supports many of its potential benefits, further studies are needed to fully understand its effects on different populations and health conditions and long term supplement use.

In my practice I have seen it help several clients, and then not at all in others.

As always, if you’re considering adding colostrum to your routine, I recommend consulting with a healthcare professional or registered dietitian to ensure it aligns with your individual health goals and needs.
