BioColostrum
Also known as: Bovine colostrum, BC, Colostrum, BioColostrum, Bovine Colostrum
Overview
Bovine colostrum (BC), often marketed as BioColostrum, is the first milk produced by cows after giving birth. It is rich in immunoglobulins (IgG, IgA), lactoferrin, growth factors, and other bioactive compounds. As a nutritional supplement, BC is primarily used to support immune function, enhance gut health, and reduce the risk of upper respiratory symptoms (URS), particularly in physically active individuals and athletes. Research suggests that BC can modulate immune responses and protect mucosal surfaces. While several randomized controlled trials (RCTs) and meta-analyses exist, the quality of evidence is mixed, with some limitations in study design and heterogeneity. Overall, BC is considered a functional food or nutraceutical with potential immunological benefits, especially in reducing URS incidence, though its effects on measurable immunological markers are less consistent.
Benefits
Bovine colostrum supplementation has shown promise in reducing the incidence of upper respiratory symptoms (URS) in healthy, physically active adults. A meta-analysis of 5 RCTs (152 participants) found that BC significantly reduced URS days by 44% and URS episodes by 38% over 8-12 weeks. However, another meta-analysis of 10 RCTs (239 participants) indicated that BC had little to no significant effect on serum immunoglobulins (IgA, IgG), lymphocytes, neutrophils, or salivary IgA concentrations. The benefits appear most relevant in physically active or athletic populations who are at increased risk of URS due to exercise-induced immune suppression. The reduction in URS incidence is clinically meaningful, potentially reducing illness-related training interruptions.
How it works
Bovine colostrum contains immunoglobulins (especially IgG), lactoferrin, and growth factors that enhance mucosal immunity and modulate systemic immune responses. It primarily acts on the mucosal immune system of the respiratory and gastrointestinal tracts. Immunoglobulins neutralize pathogens, while lactoferrin has antimicrobial and anti-inflammatory properties. Some components may act locally in the gut, but systemic absorption of intact immunoglobulins is limited in adults. The precise mechanisms by which bovine colostrum reduces URS incidence are not fully understood, and may not be fully explained by changes in measurable immunological markers.
Side effects
Bovine colostrum is generally regarded as safe, with no serious adverse effects consistently reported in clinical trials. Some individuals may experience mild gastrointestinal discomfort. Allergic reactions are possible in individuals with cow’s milk protein allergy. No significant drug interactions have been documented. Bovine colostrum is contraindicated in individuals with a known allergy to bovine milk proteins. Safety in pregnant or breastfeeding women and children requires further study. Individuals with lactose intolerance should also exercise caution. Overall, the risk of adverse effects is low, but awareness of potential allergic reactions is important.
Dosage
Studies have typically used doses of bovine colostrum ranging from 10 to 20 grams per day. Around 20 grams daily appears effective for reducing URS in athletes. There is no established maximum safe dose, but doses up to 60 grams daily have been used without serious adverse effects. Daily supplementation over 8-12 weeks is recommended for immune benefits. Powdered form is common, but capsules and tablets are also available. It is best taken on an empty stomach to avoid protein degradation. No specific cofactors are required. Individuals should start with a lower dose to assess tolerance and gradually increase as needed.
FAQs
Does BioColostrum boost immunity?
It reduces the incidence of upper respiratory symptoms in active adults but does not consistently increase serum immunoglobulin levels.
Is it safe for everyone?
Generally safe except for those allergic to cow’s milk proteins. Individuals with lactose intolerance should also exercise caution.
How long before effects are seen?
Benefits typically appear after 8 weeks of daily use, based on studies examining URS reduction in athletes.
Can it replace vaccines or medications?
No; it is a supportive supplement, not a substitute for medical treatments or preventative measures like vaccines.
Is it effective for non-athletes?
Evidence mainly supports use in physically active populations; benefits in sedentary individuals are unclear.

- https://pubmed.ncbi.nlm.nih.gov/27462401/ – This systematic review and meta-analysis of 5 RCTs (152 participants) found that bovine colostrum supplementation significantly reduced the incidence rate of upper respiratory symptoms (URS) days by 44% and URS episodes by 38% in healthy adults engaged in regular exercise over 8-12 weeks. The study suggests that BC may be an effective intervention for reducing URS in physically active individuals.
