Our verdict
Enfamil's flagship, and the longest ingredient list in mainstream US retail: lactoferrin, MFGM, and a dual HMO blend of 2'-FL and LNnT. At $2.29/oz it is also the priciest everyday formula we track, the fat blend still leads with palm olein, and parents report clumping. Skip it if the extras matter less than the bill, because Kendamil Classic gets you whole-milk MFGM for about half.

What's in it
| Protein | Nonfat milk and whey protein concentrate; the whey protein concentrate is what supplies the MFGM components Enfamil markets |
| Carbs | Lactose |
| Fats | Vegetable oil blend of palm olein, coconut, soy, and high oleic sunflower oils, plus DHA from Schizochytrium sp. and ARA from Mortierella alpina (includes palm oil) |
| Key features | Lactoferrin, a protein found in colostrum and breast milk, added as part of what Enfamil calls its premium immune blend · Dual HMO blend of 2'-FL and LNnT · Naturally occurring MFGM from the whey protein concentrate · Non-GMO, with no artificial colors, flavors, or growth hormones · Sold as a 20.5 oz powder tub, a 30 oz powder refill box, and 32 fl oz ready-to-feed bottles · Renamed from Enfamil Enspire Optimum; same recipe, new packaging |
| Stage | 0-12 months |
| Forms | powder, ready-to-feed |
| Where to find it | Walmart, Target, Kroger and its banners (Fred Meyer, Harris Teeter, QFC, Smith's, Fry's), H-E-B, Amazon, Instacart, and enfamil.com. Powder tub, powder refill box, and ready-to-feed bottles. |
Note: Price basis: Walmart's listed $46.96 for the 20.5 oz tub, which is $2.29/oz. No ASIN is recorded: the only amazon.com/dp URL confirmed during research (B085GV73MC) is a four-pack of 30 oz refill boxes, not the 20.5 oz tub this listing is priced on, so it would misdirect the buy button. The product was renamed from Enfamil Enspire Optimum to Enfamil Optimum with no recipe change; both names appear on shelves and in retailer listings. Ingredient list per retailer labeling: nonfat milk, lactose, vegetable oil (palm olein, coconut, soy, high oleic sunflower), whey protein concentrate, then under 2% including 2'-FL, LNnT, and lactoferrin. Claims about lactoferrin and closeness to breast milk are Mead Johnson's marketing, recorded here as theirs.

Common questions
What is the difference between Enfamil Optimum and Enfamil Enspire?
They are the same product. Enfamil Enspire Optimum was renamed Enfamil Optimum, with new packaging and the same nutrition. Older tubs on shelves may still carry the Enspire name.
Is Enfamil Optimum worth the price?
It costs about $2.29/oz against $1.73/oz for Enfamil NeuroPro Infant, so roughly $0.56 more per ounce for lactoferrin, a second HMO, and MFGM. If MFGM is the draw, Kendamil Classic has it from whole milk at $1.21/oz. If the lactoferrin is what you want, nothing else in mainstream US retail carries it.
What is lactoferrin in baby formula?
It is a protein found in colostrum and breast milk. Enfamil adds it to Optimum and markets it as part of a premium immune blend. Formula lactoferrin is typically sourced from cow's milk. Ask your pediatrician if you want to weigh the evidence behind it.

Similar formulas
Good Start GentlePro
The quiet overachiever of the mainstream aisle: partially broken-down whey protein, both a prebiotic and a probiotic, and a friendlier price than Similac or Enfamil.
NeuroPro Infant
Enfamil's flagship is the easiest premium formula to actually prepare: it dissolves smoothly where Similac foams.
360 Total Care
The most complete prebiotic package in a mainstream US formula, with no palm oil and hospital-brand familiarity.
