Colostrum, the first postpartum milk rich in antibodies and growth factors, is framed as a valuable ingredient for immunity and recovery — hence its use in supplements.
The full read
The post correctly describes colostrum biology (rich in immunoglobulins, growth factors) but silently generalizes that value to bovine colostrum powder sold to healthy adults — a very different audience from the newborn who biologically depends on it. In active adults, controlled trials of bovine colostrum (10-25g/day) show null-to-weak effects on blood immune markers (IgA, IgG, lymphocytes), with a firmer signal only on gut permeability and a possible reduction in upper respiratory infections in athletes. The slide from neonatal human colostrum (the post's framing) to bovine colostrum powder for wellness adults (the marketing context) deserves scrutiny. "Supports immunity" and "aids recovery" need heavy caveats for a non-athlete adult: the evidence is thin and the benefit is niche.
