Colostrum (Bovine Colostrum (IgG-Rich))
The first milk produced after birth, rich in immunoglobulins (IgG), growth factors (IGF-1, TGF-β), lactoferrin, and proline-rich polypeptides. Supports gut barrier integrity, immune function, and mucosal healing.
How it works
IgG antibodies bind gut pathogens and endotoxins. Growth factors (EGF, TGF-β) stimulate epithelial cell proliferation and repair. Proline-rich polypeptides modulate Th1/Th2 balance for immune regulation.
Key facts
- Molecular weight: Complex mixture
- Half-life: IgG: ~2-4 hours in GI tract
- Bioavailability: Oral - IgG survives gastric acid (~25-30%); growth factors act locally
- Storage: Room temperature (powder). Refrigerate after opening.
Dosing overview
- Typical dose: 5-20 g powder or 500-2000 mg capsules
- Frequency: Daily on empty stomach
- Duration: Ongoing or 8-12 week cycles
- Route: Oral (powder or capsule)
Reported benefits
- Gut barrier repair
- IgG immune support
- Reduced gut inflammation

- Reduced upper respiratory infections
- Growth factor delivery
Possible side effects
- Mild bloating initially

Research
- Bovine colostrum and intestinal permeability (2021): Reduced NSAID-induced intestinal permeability by 80% vs placebo in healthy volunteers (3-fold protective effect).
- Colostrum and athletic performance (2020): 20g/day for 8 weeks increased lean mass by 1.5kg and reduced upper respiratory illness incidence by 50% in elite athletes.
Community reviews of Colostrum
- deep_science_dee rated it 5/5 - Solid compound with real results: Been using Colostrum for about 1 month and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- stack_logic_lisa rated it 5/5 - Noticed clear benefits within weeks: Added Colostrum to my protocol about 3 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- baseline_ben rated it 4/5 - Worth adding to the protocol: Colostrum has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
- measured_mike rated it 5/5 - Genuinely effective after 2 months: Been using Colostrum for about 2 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month.

- mom_honest rated it 4/5 - quieter gut, fewer random flare-ups: after about 12 weeks on bovine colostrum, the main thing i noticed was my gut felt less reactive, which mattered a lot with my long west coast days and being on my feet at work. i’d still call it a mild win, not some dramatic fix, but imo it was real for me.
