It is interesting to note that currently the cheapest source of material from which food grade L-cysteine may be purified in high yield by hydrolysis from is human hair. Other sources include feathers and pig bristles. The companies producing cysteine by hydrolysis are located mainly in China.The post really isn't meant to be alarmist or meant to inspire outrage, certainly no more than all those bug, vermin and processing contaiminants we hear about should. Err, well, unless you're trying to eat vegan/vegetarian, kosher, or halal, I guess.
