Cellulase, Aspergillopepsin, and other fungal enzymes

Research-supported

What it is

Industrial digestive enzymes used in supplements and some food products are commonly produced via fermentation by Aspergillus niger — a mold/fungus species. The fact that an ingredient is plant-based or grain-free doesn't mean it's fungus-free.

Relevant concerns

  • AIP (Autoimmune Protocol)

    Autoimmune Protocol elimination phase excludes fungal sources; fungal-derived enzymes can sustain immune reactivity.

  • Histamine

    Fungal fermentation processes can elevate histamine levels.
