Protein is formed by dehydration and condensation of amino acids, that is to say, it is composed of amino acids one after another. In fact, there are only 20 kinds of amino acids, but due to the different spatial structure of amino acids in each protein, all protein will be decomposed into amino acids after entering the stomach, and then reassembled into the protein needed by adults. Therefore, the process of collagen is

Collagen-decomposed into amino acids-recombined-protein needed by human body.

There are 20 kinds of meat products in protein, so eating collagen is equivalent to eating amino acids and meat. In short, the human body needs amino acids to synthesize protein, but collagen will not enter your body without decomposition.

But amino acid synthesis. Protein, which the human body needs, enters the human body and becomes the new protein, so it is useless.

As for the side effects, if it is pure collagen, there should be no.

Depending on whether the manufacturer has added other chemicals.

You are satisfied with my answer.
