Long before a calf takes its first wobbly steps, a mother cow gives it colostrum — the dense, antibody-rich first milk produced in the hours after calving, nature's own head start. MDR Colostrum Immune Factors captures that same first milk in a single 500 mg capsule, complete with the naturally-occurring immunoglobulins, lactoferrin, and growth factors it's prized for. We didn't chase the cheapest supply: ours is sourced solely from United States dairies and certified free of artificial hormones, antibiotics, pesticides, GMOs, and BSE — because with colostrum, the source is the proof.

This isn't a megadose blend hiding a round number in a proprietary mix. One named active stands alone on the Supplement Facts panel, so you see exactly what you take. It's built for adults who want a quiet, year-round contribution to the immune and gut-lining defenses the body works on every day — travel weeks, busy seasons, training blocks, the long stretches when sleep and good food slip. Colostrum Immune Factors pairs with a normal diet rather than replacing one, and is made to live in a daily routine for the long run.
