We derive a few of the enzymes in VeganZyme from Aspergillus niger, but that's not to say that it's part of the final product. We use Aspergillus niger as part of the sourcing process, and then we isolate these enzymes to create our vegan-friendly formula. Overall, individuals with yeast and fungal overgrowth issues can still benefit from VeganZyme and consume it safely. We hope this helps, and if you choose to purchase our product, please know that we offer a [one-year money-back guarantee](https://globalhealing.com/help/guarantee) for your convenience and free shipping anywhere in the US and Canada.
