Quite disgusting!!!

L-cysteine.  Ever seen this on an ingredient list?  Don’t have a clue what it is?  Well let me tell you. L-cysteine is an amino acid that is sourced from duck feathers, human hair or hog hair!  I’m sure now you understand the title for this post.

For more information on L-cysteine, check out The Vegetarian Resource Group Blog.
