Enzymes are tiny stain-eating machines. Protease goes after protein stains like grass and egg. Amylase handles starch, like gravy and oatmeal. They're why some detergents work so well in cold water.

Quick answer: most detergent enzymes today are made by fermentation using microbes, not taken from animals. But it's still worth asking, because growth materials can vary.

Where enzymes come from

Long ago, some enzymes came from animal sources. Today, detergent enzymes are typically grown by microbes in big fermentation tanks, a bit like brewing.^†

So yes, your stain remover may have the same origin story as your kombucha.

What makes an enzyme vegan

• The source: microbial, not animal.
• The growth materials: what the microbes are fed.
• The testing: no animal testing on the finished product.

What to ask

If you want to be sure, ask a brand three things: how their enzymes are made, what the microbes are fed, and whether anything was tested on animals.
