Kirkland Signature ProCare Infant Formula
Costco's house-brand formula delivers name-brand-style nutrition at a warehouse price that makes your budget exhale.
The verdict
Kirkland Signature ProCare is the open secret of formula-feeding parents: it's a milk-based, iron-fortified formula with DHA and added prebiotics that meets the exact same FDA standards as the big brands, at a dramatically lower per-ounce cost. If your baby tolerates a standard milk-based formula, this is often the smartest financial move you can make, full stop. The catch is access: you need a Costco membership and it comes in large tubs, so it's less convenient for a quick grab and it can occasionally sell out. Skip it if your baby needs a specialty formula (sensitive, hypoallergenic, organic) or you don't have Costco access.
