Fat blend composition
Palm oil supplies palmitic acid (~25% of breast-milk fatty acids). Whole-milk fat preserves natural sn-2 palmitate and MFGM; sn-2 palmitate (structured palm) addresses the position issue; standard palm + supplementary oils is the conventional EU-organic approach. See the palm oil explainer for the hierarchy.
