Our Verdict
Our top pick. New Zealand sourcing is the gold standard for colostrum: rBST and antibiotics are illegal there by law, cows graze year-round, and the Ministry for Primary Industries enforces strict export standards. Antler Farms is one of the few US-available brands sourcing 100% from NZ with verifiable supply chain. Discloses IgG content and uses low-temperature processing. Not Sport-certified (no major colostrum brand is), but the structural quality advantages of NZ sourcing make this the cleanest option.
