Our Verdict
Best value from a reputable brand. Sports Research has built credibility across collagen, protein, and other categories with consistent third-party testing, and the colostrum line follows the same playbook. The trade-off is US sourcing rather than NZ — meaning rBST and antibiotic residues are theoretically possible (though tested for). At ~$0.83/serving, it's the cheapest legitimate option from a brand you've heard of.
