The differences are as follows:

1. Whey protein has many advantages such as high purity, high absorption rate, and the most reasonable amino acid composition, and is regarded as the "King of Proteins". It has the characteristics of high nutritional value, easy digestion and absorption, and contains a variety of active ingredients. It is recognized as one of the high-quality protein supplements for the human body.

2. A large, hard, dense curd that is extremely difficult to digest and decompose. Characteristics of casein: difficult to absorb.

Extended information:

1. Whey protein is a precious protein separated and extracted from milk using advanced technology. It is known for its high purity, high absorption rate, and the most reasonable amino acid composition. The advantage is promoted as the "King of Protein". ?

2. Whey protein is not only easy to digest, but also has high biological value, high digestibility, high protein efficacy ratio and high utilization rate. It is the best among proteins and is recognized as a high-quality protein for the human body. One of the supplements.

3. The composition of milk is 87% water and 13% milk solids. In milk solids, 27% is milk protein, only 20% of milk protein is whey protein, and the remaining 80% is casein, so the content of whey protein in milk is only 0.7%.

4. Casein is the main protein in mammals including cow, sheep and human milk. The protein of milk is mainly casein, while that of human milk is mainly albumin. Casein is a type of large, hard, dense curds that are extremely difficult to digest and break down.
