I think it would really amaze people if they actually read the labels of foods they ate and googled the ingredients. Collagen may not sound so gross to them then
Processed, reprocessed, canned, preserved, vacuum packed, bagged, sealed for your protection - its all got nasty stuff in it. Collagen doesn't gross me out - its not a top knotch protein but the content certainly doesn't gross me out. I eat plenty of Jello - so do most others. Its really not that different.
