Government Initiatives

Country	Key Government Initiatives
India	This is one of the most direct pushes for bio-based cysteine. It establishes Biomanufacturing Hubs to help factories switch from boiling animal feathers to using high-tech microbial fermentation. The goal is to turn India into a global smart protein hub by 2030.
Europe	The EU has set strict Regulation (EU) No 231/2012, which defines exactly what can be called food-grade L-cysteine (E 920). Crucially, the EU prohibits human hair as a source, which has forced many global suppliers to reformulate their products specifically for the European market
US	In a landmark move, the FDA issued a final guidance allowing N-acetyl-L-cysteine (NAC)-a major cysteine derivative-to be sold as a dietary supplement. Before this, it was technically banned because it was first used as a drug in the 1960s. This green light has reopened the massive U.S. supplement market for cysteine producers.
