The A2 milk source of Guanzhen Lake in Jinling comes from Yili's exclusive pasture at 45 degrees north latitude in China. It uses organic A2 milk source, and the β -casein in the milk produced is A2 type.

A2-β casein is the same as breast milk. Compared with A 1 protein used in other milk powders on the market, A2-β casein is more beneficial to the baby's absorption.

The selling point of A2-β casein, although many milk powders are imitating each other, has not been recognized by relevant EU institutions at present, so milk powder express always feels that it belongs to IQ tax.

Raw materials include raw milk, desalted whey powder and whey protein powder, which have good freshness, but it should be noted that each stage contains anhydrous cream.

Anhydrous cream is extracted from milk, which enriches the types of fatty acids and can reduce the probability of constipation if it is added enough, but for newborn babies, milk fat is not so well absorbed.
