Collagen peptide and whey protein peptide are large protein hydrolysis or enzymatic products, but the two in the protein source, the amino acid species contained in the larger differences.
1. Different sources of protein: collagen peptide is the product of collagen, which is mainly from the animal body rich in collagen, such as fish skin, pig’s feet, chicken claws, etc., and whey protein peptide is the product of whey protein, which is mainly from the milk food.
2. Different kinds of amino acids: collagen peptide source of collagen is an incomplete protein (poor quality protein), which contains less types of essential amino acids, and incomplete; and whey protein peptide source of whey protein is a complete protein (high-quality protein), which contains all kinds of essential amino acids, more than the collagen peptide.
