When you eat or drink collagen (from meat or in supplements) it is digested and broken
down into the individual amino acids it is made up of, just as it would be with any animal
protein you eat. But regardless of the source the collagen would not be distributed directly
to the collagen in your skin. It’s just not possible, any more than the chocolate in the cow
analogy. Still, eating foods containing collagen does seem to be able to help the entire body’s
formation of collagen, and that’s good news
