Colostrum
Also known as: bovine colostrum, colostrum basic protein, CBP, first milk, immune milk, camel colostrum
Effective Dosage
No established dose from provided studies for adult humans
What the Science Says
Colostrum is the nutrient-dense first milk produced by mammals immediately after birth, packed with immunoglobulins, lactoferrin, and growth factors. In preterm infants, oropharyngeal administration of mother's own colostrum has been associated with reduced rates of necrotizing enterocolitis and early-onset sepsis, and improved feeding tolerance. In animal studies, bovine colostrum supplementation improved gut barrier function, digestive enzyme activity, and growth in weaned piglets — but these findings have not been reliably replicated in healthy adult humans.
What It Doesn't Do
Not proven to fight COVID-19 or other viral infections in adults — a clinical trial of camel colostrum showed no reduction in viral load or infectivity. No evidence from the provided studies that it boosts immunity, builds muscle, or improves athletic performance in healthy adults. Don't assume animal or infant research translates to adult supplement use. The gut health benefits seen in piglets and preterm babies don't automatically apply to you.
Evidence-Based Benefits
Colostrum is rich in immunoglobulins, growth factors, and nutrients that can enhance immune function and support gut health. Clinical trials have shown it may help reduce the duration of infections and improve recovery from exercise-induced stress.

Absorption & Bioavailability
Unknown for adult humans based on provided studies. In infants, oropharyngeal administration delivers bioactive compounds directly to mucosal tissue. Whether intact immunoglobulins and growth factors survive adult digestion is not addressed in the provided data.
Red Flags to Watch For
- Most compelling evidence is in preterm infants and animals — not healthy adults
- A placebo-controlled trial of camel colostrum in COVID-19 patients showed no benefit on viral load or infectivity
- A systematic review of bovine colostrum in preterm infants concluded it cannot be recommended based on current evidence, citing likely performance bias
- 736 registered supplement products exist despite very limited human clinical evidence for adult use
- Bovine colostrum is a dairy-derived product — unsuitable for those with milk allergies or lactose intolerance
- No established effective dose for adult humans from the provided studies
