The content of collagen in pig's trotters is not as much as expected. It only exists in the epidermis of pig's trotters, and there is a lot of fat under the epidermis. It is not known whether a little collagen can be absorbed and utilized, but it is true that a lot of fat will make you fat first.

Protein obtained by eating pig's trotters can be decomposed into several amino acids and stored in the body, protein obtained by eating tofu can also be decomposed into these amino acids and stored in the body, and protein obtained by eating fish and shrimp can also be decomposed into these amino acids and stored in the body. Therefore, the amino acids that ultimately synthesize our human "collagen" may not necessarily come from "pig's trotters".
