Colostrum has a dirty little secret. The #1 selling brand in America (rhymes with “Farmra”) and many others are selling you INCOMPLETE colostrum. They remove the fat to make it "dissolve better" and sit on a shelf. But when they strip the fat, they destroy the medicine. 🧵 Here is the science they aren’t telling you. Real colostrum is a complex living matrix. It relies on the Milk Fat Globule Membrane (MFGM). This is the lipid shield that protects the bioactive components — growth factors (IGF-1, TGF-β) and immunoglobulins — from oxidation and rancidity. (PMID: 33477653, 39064802) When you de-fat colostrum, you destroy the MFGM. Without this lipid layer, the delicate bioactives are left exposed. They are far more likely to be degraded by your own stomach acid before they ever reach your bloodstream to do their job. (PMID: 33477653, 8096559) It gets worse. Removing the fat and casein also strips away Proline-Rich Polypeptides (PRPs). These are critical signaling peptides that bidirectionally regulate your immune system (calming inflammation or boosting defense). No fat and casein = far less PRPs!
