Computed from named public guides — NOT independently scholar-ratified. For doubtful items, consult a scholar you trust. Halalyzer never invents a ruling and never uses AI for the verdict.

Origin class: microbial (stated); supplement function: active. status_condition: HALAL only when explicitly synthetic or microbial-fermentation; human-hair or feather (poultry-keratin) derived l-cysteine is HARAM/MUSHBOOH; generic unstated l-cysteine (E920) stays mushbooh. Aggregation methodology, not scholar-ratified.
