From the Research
Supplemental bovine colostrum may offer some health benefits for adults, particularly in supporting immune function and gut health, but the evidence is not strong enough to recommend it as a standard health intervention. The most recent and highest quality study, published in 2021 1, suggests that bovine colostrum supplementation may have beneficial effects on preventing upper respiratory illness in sportsmen, modulating immune system response, and reducing intestinal permeability in healthy and sick subjects. However, the study also notes that the evidence is highly heterogeneous and further studies are mandatory to better understand all factors influencing its activity.
Key Findings
- Bovine colostrum contains bioactive compounds like immunoglobulins, growth factors, and antimicrobial peptides that could potentially support immune function and gut health 2, 3, 4.
- Some studies suggest modest benefits for athletic recovery, immune support during respiratory infections, and gastrointestinal health, with typical dosages ranging from 10-60 grams daily depending on the specific product and intended use 1, 5.
- The theoretical mechanism involves colostrum's immune-supporting proteins and growth factors that may help repair tissues and modulate immune responses 2, 4.
- Most adults already have developed immune systems, so the benefits are not as pronounced as they would be in newborns 1.
Recommendations
- If considering supplementation, choose products from reputable manufacturers, start with lower doses to assess tolerance, and be aware that colostrum supplements may cause mild digestive discomfort in some individuals 1, 4.
- Those with dairy allergies should avoid these supplements entirely 1, 5.
- Further studies are needed to confirm the effects, dose, and duration of treatment for bovine colostrum supplementation in adults 3, 1, 4.
