Try this site https://www.youtube.com/watch?v=yt_pSMru47U for more information on collagen versus gelatin. Gelatin is very rich in proteins. It contains 98 to 99 percent of its total protein content but it is not as nutritious as other protein sources. It is rich in the naturally-occurring amino acids glycine and proline but low in tryptophan (it does not make you sleep), isoleucine, threonine and methionine. Therefore it is important that you opt for the best source to learn about collagen versus gelatin to improve your skin. Follow us http://collagenforwrinkles.tumblr.com/collagenversusgelatin
