A co-worker told me today that he read that L-Lysine ( amnio acid ) is used for bakery products. It helps in the dough rising and adds amino acid to bread for example. What is the cheapest source many companies use for L-Lysine????? This is disgusting because it is the cheapest source in China!!!! They get L-Lysine by using human hair and usually from cadavers!!!! YUCKO!!!!
