Frequently Asked Questions Vital-Zymes™ Are animal enzymes effective for human use? Animal enzymes, which are included in many formulations, are less effective and have a possible adverse side effect. Supplying animal enzymes could reduce the body's ability to create its own enzymes, whereas pure plant enzymes do not interfere with the natural functioning of the body.
