Supplement
Colostrum
SaveFirst milk produced after birth, rich in immunoglobulins, lactoferrin, and growth factors. Bovine colostrum is supplemented for gut and immune support.
Quick verdict
Genuine immunoglobulin content with plausible gut-barrier benefits. Athlete studies show reduced URTI incidence. Not a miracle supplement but has legitimate uses.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Contains IgG, IgA, lactoferrin, and growth factors. RCTs in athletes show reduced upper respiratory infection rates during heavy training. Gut-permeability studies (NSAID-induced) show protective effects. Some evidence for exercise recovery.
Benefits
- Provides bioactive immunoglobulins (IgG, IgA)
- Reduces URTI incidence in athletes
- May protect gut barrier from NSAID damage
Dosage notes
10–20 g/day of bovine colostrum powder. Higher doses used in athletic studies. Take on an empty stomach.
Side effects
- GI discomfort
- Not suitable for dairy-allergic individuals
- Bloating
Who should be cautious
Dairy allergy/intolerance contraindicates use. Growth factor content raises theoretical (unproven) concerns in cancer survivors.
What this page cannot tell you
Quality and immunoglobulin content vary greatly between products. Pasteurisation methods affect bioactive content.
