18 Nov 2021 --- Abbott is launching its Similac 360 Total Care infant formula with five human milk oligosaccharides (HMOs) identical to those found in human breast milk. “Similac 360 Total Care is the first infant formula in the US to offer a blend of five of the most abundant HMOs across the three categories of HMOs present in breast milk,” Rachael Buck, PhD senior research fellow at Abbott, tells NutritionInsight.
