Delta milk refers to "low-lactose milk" that effectively solves the problem of "lactose intolerance" or lactase deficiency, and the hydrolysis rate can be as high as 90% or more of the high hydrolysis rate of low-lactose milk.

Different lactose intolerant and lactase deficient people have different levels of lactose tolerance. Some people can tolerate higher doses of lactose, others very low doses. One of the major obstacles to the growth of the dairy market is the large number of "lactose intolerant" or lactase deficient people in China. Symptoms of lactase deficiency include diarrhea, abdominal discomfort, bloating and abdominal pain.

Ordinary milk may cause some people to experience bloating, abdominal pain, diarrhea, and other lactose intolerance reactions, and Schwarzenegger's milk can be a good solution to this problem. This is the biggest difference between the two.
